RoHS and WEEE Compliance The Aprisa XE is fully compliant with the European Commission’s RoHS (Restriction of Certain Hazardous Substances in Electrical and Electronic Equipment) and WEEE (Waste Electrical and Electronic Equipment) environmental directives.  Restriction of hazardous substances (RoHS) The  RoHS Directive  prohibits  the  sale  in  the  European  Union  of  electronic  equipment  containing  these hazardous substances: lead*, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs). 4RF Limited has worked with its component suppliers to ensure compliance with the RoHS Directive which came into effect on the 1st July 2006.  *The European Commission Technical Adaptation Committee (TAC) has exempted lead in solder for high-reliability applications for which viable lead-free alternatives have not yet been identified. The exemption covers  communications  network  infrastructure  equipment,  which  includes  4RF  Limited  Aprisa  XE microwave radios.  End-of-life recycling programme (WEEE) The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment. Under the Directive, used equipment must be marked, collected separately, and disposed of properly. 4RF  Limited  has  instigated  a  programme  to  manage  the  reuse,  recycling,  and  recovery  of  waste  in  an environmentally safe manner using processes that comply with the WEEE Directive (EU Waste Electrical and Electronic Equipment 2002/96/EC). 4RF  Limited  invites  questions  from  customers  and  partners  on  its  environmental  programmes  and compliance with the European Commission’s Directives (sales@4RF.com).
2  |     Aprisa XE User Manual  Compliance General The Aprisa XE digital radio predominantly operates within frequency bands that require a site license be issued  by  the  radio  regulatory  authority  with  jurisdiction  over  the  territory  in  which  the  equipment  is being operated. It  is the responsibility of the user, before operating the equipment, to  ensure that where required the appropriate license has been granted and all conditions attendant to that license have been met. Changes  or  modifications  not  approved  by  the  party  responsible  for  compliance  could  void  the  user’s authority to operate the equipment. Equipment  authorizations  sought  by  4RF  Limited  are  based  on  the  Aprisa  XE  radio  equipment  being installed at a fixed location and operated in a continuous point-to-point mode within the environmental profile  defined  by  EN 300 019,  Class 3.2.  Operation  outside  these  criteria  may  invalidate  the authorizations and / or license conditions. The term ‘Terminal’ with reference to the Aprisa XE User Manual, is a generic term for one end of a fixed point-to-point Aprisa XE link and does not confer any rights to connect to any public network or to operate the equipment within any territory. Compliance ETSI The  Aprisa  XE  radio  terminal  is  designed  to  comply  with  the  European  Telecommunications  Standards Institute (ETSI) specifications as follows:  Radio performance EN 302 217 Parts 1, 2.1, and 2.2 EMC EN 301 489 Parts 1 & 4 Environmental EN 300 019, Class 3.2 Safety EN 60950   An Aprisa XE radio terminal operating in the following frequency bands / channel sizes has been tested and is compliant to the ETSI  radio specifications and suitably displays the CE logo.

 Preparation  |  23  Aprisa XE User Manual  3. Preparation Path Planning Proper path planning is essential.  When considering the components of your radio system, think about:  antenna selection and siting  coaxial cable selection  link budget You can also use Surveyor to help you with path feasibility planning. Surveyor is a path propagation calculator developed by 4RF to assist path planners quickly and efficiently verify the viability of point-to-point transmission links deploying the Aprisa microwave radio systems. The software program calculates the anticipated link performance for the transmission system elements you have selected. However, it is not a substitute for in-depth path planning. You will find Surveyor a valuable addition to your planning toolbox. A copy of Surveyor is provided on the Aprisa CD supplied with this manual. You can download updates from www.4rf.com.  Antenna Selection and Siting Selecting and siting antennas are important considerations in your system design. There are three main types of directional antenna that are commonly used with the radios parabolic grid, Yagi and corner reflector antennas. The antenna that should be used for a  particular situation is determined  primarily by the frequency of operation and the gain required to establish a reliable link. Parabolic Grid Antennas   Factor Explanation Frequency Often used in 1350-2700 MHz bands Gain Varies with size (17 dBi to 30 dBi typical) Wind loading Can be significant Tower aperture required Can be significant Size Range from 0.6 m to 3 m diameter Front to back ratio Good Cost High
24  |  Preparation   Aprisa XE User Manual  Yagi Antennas   Factor Explanation Frequency Often used in 330-960 MHz bands Gain Varies with size (typically 11 dBi to 16 dBi) Stackable gain increase 2 Yagi antennas (+ 2.8 dB) 4 Yagi antennas (+ 5.6 dB) Wind loading Less than a parabolic grid antenna Tower aperture required Unstacked: Less than a parabolic grid antenna Stacked: about the same as a parabolic grid antenna Size Range from 0.6 m to 3 m in length Front to back ratio Low Cost Low  It is possible to increase the gain of a Yagi antenna installation by placing two or more of them in a stack. The relative position of the antennas is critical.   Example of stacked antennas
 Preparation  |  25  Aprisa XE User Manual  Corner Reflector Antennas    Factor Explanation Frequency Often used in 330-960 MHz bands Gain Typically 10 dBd Wind loading Less than a parabolic grid antenna Tower aperture required About the same as a parabolic grid antenna Size Range from 0.36 m to 0.75 m in length Front to back ratio High (typically 30 dB) Beamwidth Broad (up to 60°) Cost Medium  Antenna Siting When siting antennas, consider the following points:  A site with a clear line of sight to the remote terminal is needed. Pay particular attention to trees, buildings, and other obstructions close to the antenna site.  Example of a clear line-of-sight path  Any  large  flat  areas  that  reflect  RF  energy  along  the  link  path,  for  instance,  water,  could  cause multipath fading. If the link  path crosses a feature that  is likely to cause RF reflections, shield the antenna  from  the  reflected  signals  by  positioning  it  on  the  far  side  of  the  roof  of  the  equipment shelter or other structure.  Example of a mid-path reflection path  The antenna site should be as far as possible from other potential sources of RF interference such as electrical equipment, power lines and roads.  The antenna site should be as close as possible to the equipment shelter.  Note:  Wide  angle  and  zoom  photographs  taken  at  the  proposed  antenna  location  (looking  down  the proposed path), can be useful when considering the best mounting positions.
26  |  Preparation   Aprisa XE User Manual  Coaxial Feeder Cables To ensure maximum performance, it is recommended that you use good quality low-loss coaxial cable for all feeder runs. For installations requiring long antenna cable runs, use Andrew Heliax™ or equivalent. When  using  large  diameter  feeders,  use  a  short  flexible  jumper  cable  between  the  feeder  and  the terminal to reduce stress on the antenna port connector. All coaxial cable has loss, that is, the RF energy traveling through it is attenuated. Generally speaking, the larger the diameter of the cable, the less the loss. When selecting a coaxial cable consider the following:  Factor Effect Attenuation Short cables and larger diameter cables have less attenuation Cost Smaller diameter cables are cheaper Ease of installation Easier with smaller diameter cables or short cables  When running cables:  Run coaxial cable from the installation to the antenna, ensuring you leave enough extra cable at each end to allow drip loops to be formed.  For 19-inch rack mount installations, cables may be run from the front of the rack directly onto the antenna port. They may also be run through the back of the rack to the front.  Terminate and earth or ground the cables in accordance with the manufacturers'  instructions. Bond the outer conductor of the coaxial feeder cables to the base of the tower mast.  Link Budget All of the above factors (and many others not mentioned) combine in any proposed installation to create a link budget. The link budget predicts how well the radio link will perform after it is installed. Use  the outputs of  the  link  budget  during  commissioning testing  to confirm  the  link has  been installed correctly, and that it will provide reliable service.
 Preparation  |  27  Aprisa XE User Manual  Site Requirements Power Supply Ensure that the correct power supply is available for powering the terminal. The nominal input voltage for a terminal is 12, 24 or 48 volts DC or 115 / 230 volts AC rms. The DC supply voltage is factory preset at time of order and cannot be adjusted in the field. The terminal voltage is indicated on the chassis label by the DC input connector and on the specification label fitted to the terminal.   WARNING: Before connecting power, ground the chassis using the safety earth terminal on the front panel.   Equipment Cooling Mount  the  terminal  so  that  air  can  flow  through  it.  Do  not  obstruct  the  free  flow  of  air  around  the terminal. The two internal, speed-controlled fans fitted into the chassis provide sufficient cooling. The operation of the fans is monitored and an alarm is raised under failure conditions. The environmental operating conditions are as follows:  Operating temperature -10°C to +50°C Storage temperature -20°C to +70°C Humidity Maximum 95% non-condensing

 Mounting and Installing the Terminal  |  35  Aprisa XE User Manual  External Alarms Two external alarm inputs and four external alarm outputs are provided on the RJ-45 ALARM connector on the front panel. These enable an internal alarm to provide an external alarm to the network operator's existing  network  management  system  via  contact  closure  or  opening,  or  for  an  external  alarm  to  be transported via the radio link. The latency for an alarm presented on an external alarm input to the alarm being output on an external alarm output is < 2 seconds. Alarm  outputs  are  isolated  semiconductor  relay  type  contacts  rated  0  to  60  VDC  or  AC  rms  with  a maximum current of 100 mA. Alarm inputs are  isolated current  detectors  with  an operating voltage  range of  9  to  60 VDC or  AC  rms (effective current threshold of 5.0 to 6.5 mA constant current). The  common  reference  potential  for  the  two  external  alarm  inputs  must  be  applied  to  pin  3  and  the common reference potential for the four external alarm outputs must be applied to pin 4.  Alarm Circuit Setup A typical alarm circuit setup is:  An  external  battery  applied  to  the  ‘common  alarm  inputs  reference’  and  a  normally  open  relay contact  connected  to  the  alarm  input.  Closing  the  contact  applies  the  source  to  the  alarm  input detector  which  turns  the  alarm  on  (setup  for  ‘alarm  on  when  source  on’).  See  ‘Configuring  the External Alarm Inputs’ on page 81 for the setup options.   An  external  earth  applied to the ‘common alarm outputs reference’ and a  ground contact detector connected to the alarm output. When the alarm is on (active), the external alarm output relay contact closes (setup for ‘relay closed when alarm on’). See ‘Configuring the External Alarm Outputs’ on page 83 for the setup options.    The terminal front panel RJ-45 ALARM connections are:  RJ-45 pin Connection description TIA-568A wire colour 1 External alarm input 1 green / white 2 External alarm input 2 green 3 Common reference for alarm inputs 1 to 2 orange / white 4 Common reference for alarm outputs 1 to 4 blue 5 External alarm output 1 blue / white 6 External alarm output 2 orange 7 External alarm output 3 brown / white 8 External alarm output 4 brown

DC Power Supply There are four DC power supply options for the terminal; 12 VDC, 12 VDC Low Power, 24 VDC and 48 VDC. The DC inputs are polarity critical so the DC voltage must be applied with the correct polarity.  Nominal voltage Input voltage range Maximum Power input Maximum input current Recommended DC breaker rating +12 VDC LP 10.5 to 18 VDC 53 W 5 A 8 A ±12 VDC 10.5 to 18 VDC 180 W 18 A 25 A ±24 VDC 20.5 to 30 VDC 180 W 8 A 10 A ±48 VDC 40 to 60 VDC 180 W 4 A 5 A  CAUTION: An all-pole switch or DC circuit breaker of the rating shown in the table above must be fitted between the terminal DC input and the DC power source. Each terminal or MHSB terminal should have its own separate fuse or DC circuit breaker.  12 VDC / 24 VDC / 48 VDC Power Supply The power supply DC input is isolated from ground, so the DC power input can be either positive grounded or negative grounded. The positive or negative terminal should be connected to ground.  12 VDC LP Power Supply The 12 VDC Low Power is a high efficiency power supply for low power consumption applications up to a maximum of 53 watts input power (see ‘Power Consumption’ on page 312).  The DC input on this power supply is not isolated from ground as the negative input is internally connected to  ground via the Aprisa XE chassis.  The DC power input  for this power supply  must be a  positive  12 V supply with the negative grounded.
38  |  Mounting and Installing the Terminal   Aprisa XE User Manual  DC Power Input Cabling The  DC  power  input  is  terminated  on  the  front  panel  of  the  terminal  with  two  high-current  M3  screw clamps for the positive and negative DC input and a M5 stud for the earth connection. The DC power cables have pre-terminated lugs to fit into the power input M3 screw clamps on one end and bare wire at the other end. The appropriate power cable for the power supply ordered is included in the accessory kit.   12 VDC LP / 24 VDC / 48 VDC Cable The  12  VDC  LP,  24  VDC  and  48  VDC  power  supplies  are  supplied  with  a  3  metre  red  /  black  cable  of 2.0 mm2 (23 strands of 0.32 mm2).

 Mounting and Installing the Terminal  |  43  Aprisa XE User Manual  Bench Setup Before installing the link in the field, it is recommended that you bench-test the link. A suggested setup for basic bench testing is shown below:        When setting up the equipment for bench testing, note the following:  Earthing—the terminal should be earthed at all times. The terminal earth stud must be connected to a protection earth.   Attenuators— In a bench setup, there must be 60 - 80 dB at up to 3 GHz of 50 ohm coaxial attenuation (capable  of  handling  the  transmit  power  of  +35dBm)  between  the  terminals’  N  type  antenna connectors. This can be achieved with two fixed attenuators fitted to the antennas 'N' connectors and a variable attenuator  with  a  ≥  60 dB  range.  You  can  use  other  attenuator  values  as  long  as  you  consider  the transmit power output level (max +33 dBm) and the receiver signal input (max -20 dBm).    Cables—use double-screened coaxial cable that is suitable for use up to 3 GHz at ≈ 1 metre.  CAUTION: Do not apply signals greater than -20 dBm to the antenna connection as they can damage the receiver.

48  |  Connecting to the Terminal   Aprisa XE User Manual  Connecting to the Terminal's Ethernet Interface  The  main  access  to  a  terminal  for  management  is  with  the  ethernet  interface  using  standard  IP networking. There should be only one ethernet connection from the terminal to the management network.  The  terminals  are  pre-configured  to  use  IP  addressing  in  one  of  the  common  'non-routable'  IP  address ranges.  This  means  the  terminals  are  usually  recognized  by  your  operating  system  without  any reconfiguration. However,  you should change these default  addresses  (see  ‘Changing the Terminal’s IP  Address’ on page 64) to comply with your IP addressing scheme.  In the example below, the active management PC must only have one connection to the link as shown by path . There should not be any alternate path that the active management PC can use via an alternate router or alternate LAN that would allow the management traffic to be looped as shown by path .

 Connecting to the Terminal  |  53  Aprisa XE User Manual  IP Addressing of Terminals When logging into a link, it is important to understand the relationship between the Local / Remote and the Near end / Far end terminals. The Near end terminal is the terminal that has its ethernet port physically connected to your IP network. The Far end terminal is the terminal that is at the other end of the link from the Near end terminal and communicates through the management connection over the radio link to the Near end terminal. The Local terminal is the terminal that SuperVisor is logged into and is displayed on the left hand side of the SuperVisor screen. The Local terminal can be the Near end or Far end terminal. The Remote terminal is the terminal that is at the other end of the link from the Local terminal and is displayed on the right hand side of the SuperVisor screen. To prevent confusion when operating SuperVisor, determine the IP address of the Near end terminal and log into that terminal. This is now the Local terminal. The distinction is important as:  Some functions can only be carried out on the Local terminal.  Having  different  configurations  at  each  end  of  the  link  will  disrupt  communications  between  the terminals. In these circumstances it is important to make changes to the Far end terminal of the link first.  The  link  is  then  lost  only  until  the  near  end  configuration  is  completed  and  communication restored.  If the Near end terminal is modified first, the link is lost for much longer as staff will have to either physically visit the Far end terminal to restore the link, or restore the near end to match the far end, re-establish the link, then start the process again, this time with the Far end terminal first.

 Configuring the Terminal  |  69  Aprisa XE User Manual  8. Configuring the Terminal Configuring the RF Settings The RF settings are factory-configured before dispatch to the customer requirements. However, you can change the RF settings, if required.  If  two fundamental radio parameters  (RX and TX frequency or modulation)  are changed on the  remote terminal  in  the  same  apply  action  (simultaneously),  the  first  parameter  change  could  break  the communications link to the remote terminal and prevent the other commands from being actioned. There is a two second delay between receiving the command and actioning it to allow for subsequent commands to be received before the communications link is lost.  To configure RF settings: Select Link or Local or Remote > Terminal > Basic:    Note:  Transmit  frequency,  transmit  power,  channel  size,  modulation  and  antenna  polarization  would normally be defined by a local regulatory body and licensed to a particular user. Refer to your site license details when setting these fields.
70  |  Configuring the Terminal   Aprisa XE User Manual  RX and TX Frequency The local terminal transmit frequency must match the receive frequency of the remote terminal and the remote terminal transmit frequency must match the receive frequency of the local terminal. When setting the RX and TX frequency with SuperVisor, the frequency entered is automatically resolved to the synthesizer step size for the terminal frequency band e.g. an ETSI 1400 MHz band frequency entry of 1474,010,000 Hz will  be changed to 1474,012,500 Hz (see synthesizer step size  in the table  ‘Frequency Bands’ on page 287).  The RX and TX frequency entered must be:  Within  the  frequency  band  limits  of  the  chosen  RF frequency  band of  the  terminal  as  specified  in ‘Frequency  Bands’  on  page  287. e.g. for an ETSI frequency  band of  1400 MHz, the frequency band limits are 1350 to 1550 MHz.  Within  the  TX  /  RX  passband  of  the  duplexer  fitted  in  the  terminal  e.g.  for  a  frequency  band  of 1400 MHz, the standard duplexer passband is 7 MHz and the TX / RX split is   48 MHz (see Duplexer (bandpass) ‘Duplexers’ on page 301). The duplexer passband and center frequencies are written on the duplexer label.  The TX and RX frequencies are validated against the duplexer parameters entered on SuperVisor  Link or Local or Remote > Terminal > Duplexer (see ‘Setting the Duplexer Parameters’ on page 79). If the TX or RX frequency entered is not valid i.e. outside the operating range of the duplexer, a warning message will popup. OK accepts the frequency entered and cancel rejects the frequency entered.  Important: Changing the remote terminal RX or TX frequency will disable all management communication to the remote terminal but by changing the local terminal to match the remote terminal, the radio link will be restored as will the management communication BUT  if  the  remote  terminal  RX  or  TX  frequency  is  changed  to  be  outside  the  operating  range  of  the terminal, changing the local terminal to match the remote terminal will not restore the radio link and all management communication will be lost.  The remote terminal TX and RX frequencies cannot be changed simultaneously i.e. change one direction and ‘Apply’ the change and then change the other direction and ‘Apply’ the change. To change both TX and RX frequencies: 1. Change the remote terminal RX frequency and ‘Apply’ the change. The radio link will fail. 2. Change the local terminal TX frequency to that of the remote RX frequency and ‘Apply’ the change. The radio link will restore. 3. Change the remote terminal TX frequency and ‘Apply’ the change. The radio link will fail. 4. Change the local terminal RX frequency to that of the remote TX frequency and ‘Apply’ the change. The radio link will restore.  Transmit power The transmitter power is the power measured at the duplexer output port. The transmitter power adjustment range varies depending on the Modulation type and frequency band of the terminal. For ETSI transmitter power range see ‘Transmitter Power ETSI’ on page 290.
 Configuring the Terminal  |  71  Aprisa XE User Manual  Channel size The RF channel size is a factory-configured setting determined by the Aprisa XE hardware option.  Modulation Both terminals must be set to the same modulation type.

Modem Interleaver Mode The  Modem  Interleaver  improves  modem  bit  error rate  but  increases the end  to  end link  delay  so  the Modem Interleaver should be enabled where a low bit error rate is required and disabled where a low end to end link delay is required. The ‘Default’ Modem Interleaver Mode setting is on for channel sizes of 250 kHz and greater and off for channel sizes of 200 kHz and less. The specification of end to end link delay for both interleaver on and off is given in the relevant RF Specification section. For ETSI Link Delays, see ‘Link Delays ETSI’ on page 292. When you change the Modem Interleaver Mode in an operational terminal, traffic across the link will be interrupted. Both terminals must be set to the same Modem Interleaver Mode.
 Configuring the Terminal  |  73  Aprisa XE User Manual  Modem Mute Mode The Aprisa XE radio always mutes its interface ports when the modem loses lock. The  Modem  Mute  feature  mutes  its  interface  ports  when  the  modem  Reed  Solomon  forward  error correction capability can no longer correct errors.    This can occur when the signal strength of the  RF link  reduces to within about 2  dB of the theoretical sensitivity  of the  radio  or  when the radio is  operating  well above  the  sensitivity threshold  but  is in  an environment subject to impulse noise interference on the RF path. When the mute activates;  On  the  analog  cards,  Q4EM, DFXS and  DFXO, the audio  path  mutes and the signalling states go idle.  On the digital cards, QV24  and HSS, it causes  an all ones data pattern to be driven on the RXD output line and handshake lines such as RTS / CTS to their off states while on the QJET card it forces the ports to an AIS state.  The Modem Mute feature effectively reduces the radio receiver sensitivity by 2 to 3 dB from its published values but will prevent errors from corrupting the tributary audio circuits.  Modem Mute Time The  Modem Mute  Time determines the time the mute  will persist  after  the  last  uncorrectable block  is received. This can be set from 0 to 10 seconds in 0.1 second steps.  Note: The Modem Mute feature is only available if the radio modem is Rev D or later. If the radio has a Rev A, Rev B or Rev C modem, the modem mute functionality is not displayed in SuperVisor.

 Configuring the Terminal  |  85  Aprisa XE User Manual  Configuring SNMP Settings In addition to web-based management (SuperVisor), the terminal can also be managed using the Simple Network Management Protocol (SNMP). MIB files are supplied, and these can be used by a dedicated SNMP Manager, such as Castle Rock's SNMPc (www.castlerock.com), to access most of the terminal's configurable parameters.  However,  it  is  recommended  that  SNMP  is  only  used  for  status  and  alarm  monitoring  of  your  entire network. SuperVisor is the best means to configure individual terminals. For communication between the SNMP manager and the terminal, Access Controls, Trap Destinations, and Community strings must be set up as described in the following sections.  A SNMP Access  Control is the IP address  of the  terminal used  by an SNMP manager or any other SNMP device to access the terminal. Entering an IP address of ‘Any’ (not case sensitive) or * will allow any IP address access to the terminal. A community string is sent with the IP address for security.  Commands  are  sent  from  the  SNMP  manager  to  the  terminal  to  read  or  configure  parameters  of  the terminal e.g. setting of interface parameters.  A SNMP Trap Destination is the IP address of a station running an SNMP manager. A community string is sent with the IP address for security. Events are sent from the terminal to the SNMP manager e.g. alarm events.  A  SNMP  Community  String  is  used  to  protect  against  unauthorized access (similar to  a  password).  The SNMP  agent  (terminal  or  SNMP  manager)  will  check  the  community  string  before  performing  the  task requested in the  SNMP message . Trap Destinations and Access Controls both use  community strings for protection.  To configure Trap Destinations and Access Controls: Select Local > Maintenance > SNMP > SNMP Settings    Note: SNMP Settings can only be setup on the local terminal.

 Configuring the Traffic Interfaces  |  91  Aprisa XE User Manual  9. Configuring the Traffic Interfaces  Important:  When configuring a link, it is important that you configure the remote terminal first as the new configuration may break the management connection to the remote terminal. Once  the  remote  terminal  has  been  configured,  the  local  terminal  should  be  configured  to  match  the remote terminal.  Viewing a Summary of the Interfaces To view a summary of the interfaces fitted: Select Link or Local or Remote > Interface > Interface Summary.    The Interface Summary page shows:  The interface type for each slot that has been configured with the capacity used by each port.  Total Capacity. The total capacity of the radio link.  Ethernet Capacity. The capacity allocated to the Ethernet traffic over the radio link. This includes the user and management capacity assigned.  Management Capacity. The capacity allocated to the management conduit over ethernet.  Radio Capacity. The percentage of the total capacity of the radio link that has been allocated to traffic interfaces.  Drop and insert capacity. The percentage of the total drop and insert capacity used for local drop and insert cross connections. The total drop and insert capacity is 65536 kbit/s minus the assigned radio link capacity. Some interfaces also require extra bandwidth to be allocated to transport signalling, such as CTS / DTR handshaking  or  E&M  signals.  The  cross  connections  application  automatically  allocates  capacity  for signalling when it is needed.
92  |  Configuring the Traffic Interfaces   Aprisa XE User Manual  Configuring the Traffic Interfaces  Important: Before you can configure the traffic interfaces, the interface cards must be already installed (see ‘Installing Interface Cards’ on page 235).  Configuring each traffic interface involves the following steps (specific instructions for each interface card follow this page). First, specify the port settings for the Remote terminal: 1. Select  Remote  >  Interface  >  Interface  Summary,  select  the  interface  card  and  click  Configure Interface. 2. Select the port you want to configure and modify the settings, as necessary. 3. Click Apply to save the changes you have made.  Now specify the port settings for the Local terminal: 1. Select Local > Interface > Interface Summary, select the interface card and click Configure Interface. 2. Select the port you want to configure and modify the settings, as necessary. 3. Click Apply to save the changes you have made.  Once you have done this, you will need to configure the traffic cross-connects (see ‘Configuring the traffic cross connections’ on page 145) for each interface card.
 Configuring the Traffic Interfaces  |  93  Aprisa XE User Manual  Ethernet Switch In  the  default  mode,  the  Ethernet  switch  passes  IP  packets  (up  to  1522  bytes)  as  it  receives  them. However, using SuperVisor you can configure VLAN, QoS and port speed settings to improve how IP traffic is managed.  This  is  useful for operators  who  use  virtual  networks  to  segment  different  groups  of  users  or  different types of traffic in their network. These groups can be maintained across the radio link thus ensuring users in one virtual network cannot access data in other virtual networks.  The switch also has a high-speed address lookup engine, supporting up to 2048 preferential MAC addresses as well as automatic learning and aging. Traffic is filtered through this table and only traffic destined for the remote end is sent across the link improving bandwidth efficiency.  Note: You need ‘modify’ or ‘admin’ privileges to configure the Ethernet for VLAN and Quality of Service (QoS).  VLAN tagging By default, all user and management traffic is allocated the same VLAN across the link.  Alternatively, you can assign each of the four Ethernet ports to a VLAN. Each VLAN can be configured to carry  user  traffic,  or  user  traffic  and  radio  management  traffic.    The  VLAN  tagging  conforms  to  IEEE 802.1Q standard.
94  |  Configuring the Traffic Interfaces   Aprisa XE User Manual  Configuring the Ethernet switch for VLAN tagging 1. Select Link or Local or Remote > Interface > Ethernet Settings. Note: Always configure the remote terminal before the local terminal 2. In the Quick Links box at the bottom of the page, click Ethernet General Settings.  3. From  Ethernet  Grouping  drop-down  list  select  'Enabled'  ('Disabled'  is  the  default  setting;  Ethernet traffic is not segregated). Important: Changing this setting will disrupt Ethernet traffic.     4. Click Apply to apply changes or Reset to restore the previous configuration.  You now need to select the VLAN groups for each of the four Ethernet ports.
 Configuring the Traffic Interfaces  |  95  Aprisa XE User Manual  Specifying the VLAN ID for the Ethernet Ports Each Ethernet port can be configured with one of five VLAN IDs. You can configure each of the physical ports, numbered 1 to 4 with a VLAN ID (numbered User1 to User4 and User+Mgmt).  These VLAN IDs are applied at the ingress port and only used internally across the link. The VLAN ID is removed when traffic exits the switch at the egress port. Data entering the Ethernet switch on ports 1 to 4 or the internal management port can only exit on ports that are associated with the same VLAN ID as the ingress port.  For example, the physical RJ-45 port 1 may be on VLAN 3 at the local end, but at the remote end, the physical RJ-45 port 4 may be associated with VLAN 3. Traffic entering the local end on port 1 will exit the remote end on port 4. To allow the radio link to transport  traffic  using  existing VLAN ID information, the radio adds an  extra VLAN ID over the top of an existing VLAN ID (double-tagging). This extra VLAN ID is added at the ingress port  and  removed  at  the  egress  port.  This  adds  4  bytes  to  the  packet  and  the  maximum  packet  size supported by the radio is 1526 bytes. Note 1: Tagged flows can only have one port per VLAN ID on each terminal. Note 2: The ethernet switch only supports packets up to 1522 bytes in size at the ingress port.  1. Select Link or Local or Remote > Interface > Ethernet Settings. Note: Always configure the remote terminal before the local terminal 2. In the Quick Links box at the bottom of the page, select the port you want to configure:  3. The Ethernet Port Settings page appears for the port you selected:    4. From the Ethernet Group drop-down list, select the VLAN group to which you want this port to belong. Important: To access radio management traffic, you need to allocate one of the VLANs to ‘User and Management’. It is strongly recommended that you indicate which port or group of ports is associated to the management traffic first. 5. Click Apply. 6. Repeat steps 1-4 for the Ethernet switch in the other terminal in the link.
96  |  Configuring the Traffic Interfaces   Aprisa XE User Manual  Quality of Service Quality of Service (QoS) enables network operators to classify traffic passing through the Ethernet switch into prioritized flows. Each  port can have  a  priority  tag  set  at the ingress port, or  it can  be  read  directly from  the Ethernet traffic.  When  read  directly  from  the  Ethernet  traffic,  the  following  fields  are  used  to  determine  the traffic’s QoS priority.   The IEEE 802.1p Priority information in the IEEE 802.3ac Tag.  The IPv4 Type of Service field.  The IPv6 Traffic Class field.  You can select one of two queuing methods:  IEEE 802.1p standard method  Cisco-proprietary method The queuing method determines how the traffic is prioritized. Each port has four egress queues (queues 0-3) of differing priorities. Queue 0 is the lowest priority and Queue 3 is the highest priority.  Configuring the Ethernet Switch for QoS 1.

 Configuring the Traffic Interfaces  |  97  Aprisa XE User Manual  4. Select the Priority Queue Scheduling.  There are two methods for transmitting the Ethernet traffic queues across the link:  Strict: the queue is transmitted based on the priority. The first queue transmitted is the highest priority queue and the terminal will not transmit any other traffic from any other queue until the highest priority queue is empty. Then the next highest priority queue is transmitted, and so on.  Weighted (default): each of the queues will transmit a number of packets based on a weighting. The following table shows how the weighting is applied to each queue.  Queue Priority Number of packets transmitted Queue 3 Highest Priority 8 packets Queue 2  4 packets Queue 1  2 packets Queue 0 Lowest Priority 1 packets  5. Select the IEEE 802.1 Priority Queue Mapping.  This  determines  the  standard  (or  scheme)  used  for  prioritizing  traffic  into  one  of  four  queues numbered 0 to 3 (3 being the highest priority queue). There are  two  possible  methods  for  queuing  the  ethernet traffic.  One  is  based on  the IEEE 802.1D standard (which is the default setting), and the other is based on the Cisco-proprietary method.  The following table shows how traffic is queued using the two methods:    Output Queue Priority Traffic Type Cisco Priority Queuing IEEE 802.1D Priority Queuing 0 (default) Best Effort 0 1 1 Background 0 0 2 Spare 1 0 3 Excellent Effort 1 1 4 Controlled Load 2 2 5 ‘Video’ < 100ms latency and jitter 2 2 6 ‘Video’ < 10ms latency and jitter 3 3 7 Network Control 3 3

The priority specifies where the priority control information is sourced from. From Frames Traffic is prioritized into one of the following traffic types (numbered 0 to 7) by the originating device or application. Generally, the higher the priority, the higher the priority rating. However, in the IEEE standard queuing scheme, the ordering of the priority is 1, 2, 0, 3, 4, 5, 6, 7. In this case 0 has a higher priority than 1 and 2.  If priority control information is present in the Ethernet header, this information is used to priorities the traffic but if there is no priority control information in the Ethernet header, the IP header is used to priorities the traffic.  Low, Medium, High, Very High The  priority  rating  you  select  is  applied  to  all  traffic  on  the  port  and  is  applied  to  all  traffic irrespective of traffic type and the priority control information in the traffic.  5.

Note:  The  Ethernet ports on  the  terminal are set to  auto-configure  the  speed and  duplex for the best performance.  Resetting the Ethernet Settings You can easily reset the VLAN and QoS settings to the default values, if required. This is useful if you want the  Ethernet  switch  to  operate  in  the  default  mode,  that  is,  IP  packets  are  passed  across  the  link  as received. Note: You can also do this using the Setup menu (see page 57.).  1. Select Link or Local or Remote > Interface > Default Ethernet Settings.    Set Ethernet Groupings To Default Values.  This  resets  the  Ethernet  Grouping  setting  to  'Disabled',  which  means  that  the  Ethernet  switch  no longer  operates  as  a  VLAN.  In  addition,  all  the  Ethernet  ports  will  default  to  the  'User  and Management' Ethernet Group.  Set Ethernet QoS To Default Values.  This  resets  the  ingress  rate  for  all  the  ports  to  'Unlimited'  and  the  priority  to  'From  Frames'.  In addition,  the  Ethernet  QoS  settings are  reset  to  the  defaults:  Priority  Queue Scheduling reverts  to 'Weighted' and IEEE 802.1 Priority Queue Mapping reverts to 'IEEE Standard'.  2.

This is  done  by  adjusting the circuit  levels  relative  to the 0  dBm (± 118 peak code) for example:  If a nominal input level of -6.0 dBm is applied to the Q4EM interface input port, the Q4EM Input Level must be set to -6.0 dBr. This will effectively amplify the sent signal by 6.0 dB to produce a digital signal with a ± 118 peak code (0 dBm).  If a nominal output level of -6.0 dBm is required from the Q4EM interface output port, the Q4EM Output Level must be set to -6.0 dBr. This will effectively attenuate the received decoded signal by 6 dB.  4. Set the Q4EM E wire interface to either Normal or Inverted.

 Configuring the Traffic Interfaces  |  107  Aprisa XE User Manual  Loop Interface Circuits  DFXO / DFXS Loop Interface Circuits Function The function of DFXO / DFXS 2 wire loop interface circuits is to transparently extend the 2 wire interface from the exchange line card to the telephone / PBX, ideally without loss or distortion. The DFXO interface simulates the function of a telephone and a DFXS interface simulates the function of an exchange line card. These circuits are known as ‘ring out, dial in’ 2 wire loop interface circuits. Network Performance The overall Network Performance is dependant on the number of D-A and A-D conversions and 2 wire to 4 wire / 4 wire to 2 wire conversions in the end to end circuit (telephone to telephone). To achieve the best overall Network Performance, the number of D-A and A-D conversions and 2 wire to 4 wire / 4 wire to 2 wire conversions should be minimized. Circuit Performance The  circuit  quality  achieved  with  a  2  wire  voice  circuit  is  very  dependant  on  the  external  interface parameters and the interconnecting copper line. Short interconnecting  copper  lines  (<  100  meters),  have  little effect on  the circuit  performance  so  the interface parameters have the dominant affect on circuit performance. As  the  length  of  the  interconnecting  copper  line  is  increased,  the  attenuation  of  the  analogue  signal degrades circuit performance but also the impedance of the copper line also has a greater effect on the circuit performance. For this reason, complex line impedance networks (e.g. TBR21, TN12) were created which model the average impedance of the copper network. The factors that affect the quality of the circuit achieved are; DFXO interface  The  degree  of  match  between  the  DFXO  line  termination  impedance,  the  impedance  of  the interconnecting copper line and the exchange line card line termination impedance. This affects the return loss.  The  degree  of  match  between  the  DFXO  line  termination  impedance,  the  impedance  of  the interconnecting copper  line and the exchange  line  card  hybrid  balance  impedance.  This  affects the exchange line card transhybrid balance.  The  degree  of  match  between  the  DFXO  hybrid  balance  impedance,  the  impedance  of  the interconnecting copper line and the exchange line card line termination impedance. This affects the DFXO transhybrid balance.  The circuit levels of both the DFXO and the exchange line card.

108  |  Configuring the Traffic Interfaces   Aprisa XE User Manual  Line Termination Impedance The line termination impedance (Zt) is the impedance seen looking into the DFXO or DFXS interface. The line termination impedance is not the same as the hybrid balance impedance network (Zb) but can be set to the same value. Changing  the  DFXO  /  DFXS  impedance  setting  on  the  Aprisa  XE  changes  both  the  line  termination impedance and the hybrid balance impedance to the same value.  Hybrid Balance Impedance The hybrid balance impedance (Zb) is the impedance network on the opposite side of the hybrid from the DFXO  /  DFXS  line  interface.  The  purpose  of  this  network  is  to  balance  the  hybrid  to  the  impedance presented to the DFXO / DFXS line interface. Changing  the  DFXO  /  DFXS  impedance  setting  on  the  Aprisa  XE  changes  both  the  line  termination impedance and the hybrid balance impedance to the same value.  Transhybrid loss Transhybrid loss is a measure of how much analogue signal received from the remote terminal is passed across the hybrid and sent to the remote terminal. The transhybrid loss is maximized when the hybrid balance impedance matches the impedance presented to the DFXO / DFXS line interface. An optimized hybrid minimizes circuit echo.

No signal is represented by the code step 0. A nominal level of 0 dBm generates a peak code of ± 118 which allows up to + 3.14 dBm0 of headroom before  the  maximum  step  of  127  is  obtained.  Any  level  greater  than  + 3.14  dBm0  will  be  distorted (clipped) which will cause severe problems with analogue data transmission. It  is  therefore  important  that  analogue  signals  presented  from  the  DFXO  /  DFXS  line  interface  be normalized to fit within the ± 127 quantizing steps of the encoder. This is done by adjusting the circuit levels relative to the 0 dBm (± 118 peak code) for example:  If a nominal input level of +1 dBm is applied to the DFXS line interface, the DFXS Input Level must be  set  to  +1.0  dBr.  This  will  effectively  attenuate  the  sent  signal  by  1  dB to  produce  a  digital signal with a 118 peak code (0 dBm).  If a nominal output level of -6 dBm is required from the DFXS line interface, the DFXS Output Level must be set to -6.0 dBr. This will effectively attenuate the received signal by 6 dB.  The circuit levels and the transhybrid loss of both ends of the circuit, also determine the stability of the circuit. If the circuit levels are too high and the transhybrid loss figures achieved are too low, the circuit can have a positive loop gain and can recirculate (sometimes called singing). Typically,  an  end  to  end  2  wire  voice circuit  is engineered  to  have  a  2-3  dB loss  in  both  directions of transmission.  2WS2WR 2WS input2WR output0 dBr -6.0 dBr+1.0 dBr-8.0 dBm+1.0 dBm-2.0 dBm0 dBr0.0 dBm-4.0 dBr-1.0 dBr-6.0 dBmDFXSInterfaceDFXOInterface2WS2WR-6.0 dBr+1.0 dBr-1.0 dBm0 dBr0.0 dBm0 dBr-2.0 dBmExchangeLine CardAprisa XEOverall Loss = 3.0 dBOverall Loss = 8.0 dBDerived System Level PlanNote 1: The derived system loss is 2 dB in both directions due to the deliberate 2 dB level mismatch betweenthe exchange line card and the DFXO interface unitZBZBZBTransmissionReference Point4WR4WS4WR4WS4WR4WS

 Configuring the Traffic Interfaces  |  139  Aprisa XE User Manual  HSS Clocking Types HSS internal clocking Internal clocking relies on the (highly accurate) terminal system clock, that is, it does not allow for any independent clocks coming in from client equipment. For this mode, all incoming clocks must be slaved to a clock emanating from the HSS card.  HSS pass-through clocking The HSS card is capable in hardware of passing two clocks from one side of a link to the other. Passing a clock means that the difference between the client clock(s) and the terminal clock is transferred across the link continuously. Passing a single clock in each direction requires 40 kbit/s additional link overhead, passing  two  clocks  from  DTE  to  DCE  requires  56  kbit/s  overhead,  whereas  relying  on  internal  clocking requires no overhead. Network  topology  determines  if  passing  a  clock  makes  sense.  Passing  a  clock  is  used  where  a  client's incoming clock must be kept independent of the clock sourced by the HSS card. The only time it makes sense to pass two clocks is when a client DCE in one of the HSS modes provides two independent clocks, that is, the HSS is set to Clock Mode 2. Pass-through  clocking  does not  require using the  HSS  incoming clock as  a  Primary or  Secondary master clock for the link, but does not preclude it either.  HSS primary / secondary master clocking When  implementing  an  external clock  master,  all  other  interfaces in  the  terminal  and  internal  system timings are slaved to this external clock. The  remote terminal is also slaved to  this master clock. This master clock must be within 100 ppm of the accuracy of the terminal system clock, otherwise the terminal will revert to using its internal clock. Ideally, the external clock should be much better than 100 ppm. Mode 6 is offered for those network topologies that require RxC and TxC to be locked. For example, this is useful when interworking with an Aprisa SE HSS interface.

This is the preferred dual external clock system. Both clocks travel in the same direction from DTE to DCE. This mode is used when it is important that the externally supplied RxC and TxC are maintained independently. This is almost only required in cascaded (that is, multi-link) networks. This mode cannot be used in conjunction with any interface conversion to / from X.21.

 Cross Connections  |  145   10. Cross Connections Embedded Cross Connect Switch The embedded cross-connect switch distributes capacity to each of the interfaces. Traffic can  be  distributed  to  any of  the  possible  32  interface  ports  as  well as  the  integrated Ethernet interface. This  provides the flexibility to reconfigure traffic as the network demand changes, or groom user traffic onto E1 / T1 bearers between equipment. The  maximum  number  of  simultaneous  cross  connections  per  terminal  is  256.  During  cross  connection activation, a progress bar shows the number of ports that have activated.  Link Capacity Utilization Cross connections are able to utilize all of the available capacity of the link on lower capacity radio links (<  2048  kbit/s  gross  capacity,  i.e.  up  to  500  kHz,  16  QAM).    However,  as  higher  capacity  radio  links allocate  bandwidth  for  E1  /  T1  timeslot  connections  on  64  kbit/s  boundaries,  some  capacity  may  be unusable (< 64 kbit/s).  The Cross Connections Application The Cross Connections application is a software application that is used to:  manage the cross connections switches within the terminals  create cross connections between the traffic interface ports within one terminal or between the near end and far end terminals via the radio bearer  create  cross  connections  between  symmetrical  traffic  interface  ports  with  the  symmetrical connection wizard  get the current cross connection configuration from the terminal  send and activate the cross connection configuration  save and load configuration files  The Cross Connections System Requirements The Cross Connections application requires the following minimum PC requirements:  1024 x 768 screen resolution  Ethernet interface  Java Virtual Machine
146  |  Cross Connections   Aprisa XE User Manual  Installing the Cross Connections Application The  Cross  Connections  application  is  usually  started  directly  from  SuperVisor  without  the  need  for installation. However,  if  you  want  to  use  the  Cross  Connections  application  offline  (without  any  connection  to  the terminals), you can install it on your PC. Working offline enables you to simulate new cards or terminal capacities.  The  cross  connections  can  then  be  configured  and  the resulting  configuration file  saved for later deployment. To install the Cross Connections application on your PC, navigate to the Cross Connect  directory on the supplied CD and copy the application (ccapp_exe_x_x_x.jar where x is the version) to a suitable place on your PC hard disk. Your PC 'File Types' must associate a *.jar file with the Executable Jar File so that when the *.jar file is clicked on (or double clicked on), it will be executed with Javaw.exe. If clicking on (or double clicking on) the jar file does not bring up the Cross Connections application, the 'File Types' needs to be setup in your PC.   Go to 'My Computer / Tools / Folder Options / File Types’ and click 'New'.  Type 'Jar' in the 'File Extension' box and click OK.  Click 'Change' and 'Select a program from a list'  Select 'Javaw.exe' and click OK.   Opening the Cross Connections Application To open the Cross Connections application from within SuperVisor: Select Link > Interface > Cross Connections  To open the Cross Connections application without SuperVisor: Navigate to the installed cross connections application file C-capp_exe_8_6_7.jar and double click on it.  Note: This  assumes that you have copied the cross connections application to your PC so you can work offline (without any connection to the terminals).

 Cross Connections  |  161   E1 Framed Modes  Framed Mode Description E1 – PCM 30 Provides 30 timeslots to transport traffic. Timeslot 16 carries channel associated signalling data (CAS). E1 – PCM 31 Provides 31 timeslots to transport traffic. Timeslot 16 can be used for common channel signalling or to transport traffic. E1 – PCM 30C Same as E1 – PCM 30 mode but supports CRC-4. E1 – PCM 31C Same as E1 – PCM 31 mode but supports CRC-4.  E1 CRC-4 (cyclic redundancy check) is used to ensure correct frame alignment and also used to gather E1 performance statistics e.g. Errored Seconds (ES), Severely Errored Seconds (SES).  The first three bits of timeslot 0 NFAS (bits 0,1 & 2) and all of timeslot 0 FAS are not transported  across the link, but rather terminated and regenerated at each terminal.  The  last  five  bits  of  timeslot  0  NFAS  (bits  3  –  7)  are  the  National  Use  Bits  (NUBs)  which  can  be  cross connected locally or over the link.  E1 - PCM 30 mode E1 - PCM 30 modes are used when access to the signalling bits (ABCD) is required, for example:  Splitting a PCM 30 E1 into two separate PCM 30 E1s  Cross connecting signalling from DFXS, DFXO or Q4EM interfaces into an PCM 30 E1  Drop and Insert connections between PCM 30 E1s  In PCM 30 / PCM 30C mode, the timeslot table left column is used to map timeslot bits and the timeslot table right column is used to map CAS bits (ABCD) for signalling. Timeslot 16 is reserved to transport the CAS multi frame. One use of this mode is to connect the 4 wire E&M interfaces to third-party multiplexer equipment over the E1 interface using CAS in TS16 to transport the E&M signalling. To configure this mode correctly, you must have a detailed knowledge of the CAS signalling modes for the third-party equipment to ensure the signalling bits are compatible and configured to interoperate.   E1 - PCM 31 mode E1 - PCM 31 modes are used to cross connect timeslots bits without the signalling bits (ABCD). TS16  can  be  cross  connected  between  E1  ports  (to  transport  the  entire  CAS  multi  frame)  or  used  for common channel signalling or to transport traffic. The timeslot table left column is used to map timeslot bits but the timeslot table right column for CAS bits (ABCD) is not used.

There is no CRC capability with the SF. T1 SF - DMS Provides 24 timeslots to transport traffic using the G.704 12 frame Super Frame with DeMultiplexed Signalling  (CAS AB bits). There is no CRC capability with the SF. T1 ESF - PTS Provides 24 timeslots to transport traffic using the G.704 24 frame Extended Super Frame with Pass Thru Signalling (PTS) and CRC. T1 ESF - DMS Provides 24 timeslots to transport traffic using the G.704 24 frame Extended Super Frame with DeMultiplexed Signalling  (CAS ABCD bits) and CRC.  T1 SF - PTS mode T1 SF - PTS mode provides 24 timeslots to transport traffic using the G.704 12 frame Super Frame without demultiplexing the signalling. Pass  Thru  Signalling  provides  cross  connection  of  the  entire  framed  T1  timeslot  between  T1  ports (including the inherent robbed bit signalling). This is the most efficient method of transporting a framed T1 over the radio link as no additional radio link capacity is required to transport the signalling because the CAS is not demultiplexed.  To  maintain  multi  frame  alignment  between  two  framed  T1  ports,  a  FPS  (Frame  Pattern  Sync)  bit  is required  to  be  cross  connected  between  the  two  framed  T1  ports.  This  FPS  bit  requires  an  additional 8 kbit/s of radio link capacity.  The timeslot table left column is used to map timeslot bits but the timeslot table right column for CAS bits (ABCD) is not used.  T1 SF - PTS mode is used when access to the signalling bits is not required but are transported between T1s, for example:  Drop and Insert connections between Super Frame T1s or data interfaces  T1 SF – DMS mode T1 SF – DMS mode provides 24 timeslots to transport traffic using the G.704 12 frame Super Frame with four state demultiplexed signalling using the AB bits each with a bit rate of 333 bit/s. DeMultiplexed Signalling allows the cross connection of framed T1 ports to other interface ports e.g. to a Q4EM or HSS. An additional 8 kbit/s of radio link capacity is required to transport each CAS bit over the radio link.  The mapping left column is used to map timeslot bits and the timeslot table right column is used to map the CAS A&B bits for signalling (C&D bits are not used).  T1 SF – DMS mode is used when access to the signalling bits is required, for example:  Cross connecting signalling from a Q4EM interfaces into a 12 frame Super Framed T1.

 Protected Terminals  |  181  Aprisa XE User Manual  11. Protected Terminals Monitored Hot Stand By (MHSB) This section describes configuring the protected terminal in MHSB mode. A protected terminal in MHSB mode comprises two radios interconnected using a MHSB switch. This MHSB switch comprises one RF switch and up to four tributary switches depending on the number of tributaries requiring switching:      The  MHSB  switch  protect  terminals  against  any  single  failure  in  one  radio.  It  also  monitors  the  alarm output of each radio and switches between radios if major radio link alarms occur. The MHSB switch will not allow a switch to a faulty radio. The MHSB switch uses a CPU to monitor the alarm status received from both the connected radios' alarm ports.  When  a  relevant  major  radio  link  alarm  is  detected  on  the  active  radio  (that  is,  transmitter, receiver, power supply or modem), the CPU switches a bank of relays that switches all the interfaces and the transmit port from the main  radio to a functioning stand-by radio. The stand-by radio now becomes the active radio. The MHSB switch has a hysteresis of 30 seconds to prevent switching on short alarm transients. The tributary switch and the RF switch are both a 19-inch rack-mount 1U high chassis. The MHSB switch option is available for all Aprisa XE frequency bands.

186  |  Protected Terminals   Aprisa XE User Manual  Configuring the Radios for Protected Mode  The  MHSB  switch  does  not  require  any  special  software.  However,  the  radios  connected  to  the  MHSB switch  must  be  configured  to  work  with  the  MHSB  switch.  This  sets  the  alarm  outputs  and  inputs  to function in MHSB mode. You must configure  the interfaces of both radios connected to the MHSB switch identically. To perform this, you can either connect directly to the radio or use the test mode of the MHSB switch.  MHSB Terminal IP Addresses Before configuring the link, you must ensure that the two independent links have correctly configured IP address details. All four radios in the protected link must be on the same subnet.    Example of MHSB IP addressing

In  general,  mount  radio  A  above  the  MHSB  switch  and  radio  B  below  the  MHSB switch:  There is an Ethernet connection between any of the four Ethernet ports on each radio and the Ethernet port  on  the  Tributary  switch.  There  is  also  a  connection  between  radio  A  and  radio  B,  which  ensures Ethernet traffic is maintained if a radio loses power. The  Ethernet  port  on  the  protection  switch  can  be  connected  to  an  Ethernet  hub  or  switch  to  allow multiple connections. Important: The management Ethernet capacity on each of the four radios in the protected terminal must be  identical  for  remote  communications  to  work  and  there  should  only  be  one  IP  connection  to  the management network (via the tributary switch Ethernet port).
188  |  Protected Terminals   Aprisa XE User Manual  Configuring the Terminals for MHSB It is recommended that you configure the local and remote A side first, then the local and remote B side. Both the local A and B radios must be configured identically, and both the remote A and B radios must be configured identically. Tip: As illustrated below, you  may find it helpful to have two browser sessions  running simultaneously. You can then easily see both the A and B sides of the protected link. To configure MHSB operation: 1. Select Link > Maintenance > MHSB.    2. Enable MHSB mode. 3. Select whether the radio is A or B. Ensure  that the  radio  connected  to  the  A  side  of  the  protection  switch  (normally  above  the  MHSB switch) is  set to  Radio A and the  radio connected to  the  B  side of  the  protection  switch (normally below the MHSB switch) is set to Radio B. In the event of a power outage, the radios will switch over to the A side of the protection switch when the power is restored. The A side is also the default active side.  4. When  you  have  made  your  changes,  click  Apply to  apply  changes  or  Reset  to  restore  the  previous configuration. 5. Repeat steps 2 to 4 for the other side of the protected link.
 Protected Terminals  |  189  Aprisa XE User Manual  Clearing MHSB Alarms If a switchover event occurs, the OK LED on the front panel and on the Terminal status and menu bar in SuperVisor changes to amber. 1. Select Clear Switched Alarm from the MHSB Command drop-down list.    2. Click Apply to apply changes or Reset to reset the page.  Note:  When  MHSB  mode  is  enabled,  external  alarm  input  2  is  used  by  the  protection  system  to  carry alarms from the protection switch to the radio. In MHSB mode, therefore, only external alarm input 1 is available for user alarms.
190  |  Protected Terminals   Aprisa XE User Manual  Hitless Space Diversity (HSD)  HSD provides hitless RF receive path protection and hot standby transmitter redundancy.  It is typically deployed for paths where high path availability is required.  An Aprisa XE hitless space diversity terminal comprises two radio terminals, radio A and radio B. Radio A is the primary radio which is fitted with the interface cards and connects to antenna A. Antenna A always carries the transmitted signal and the received signal for Radio A. Radio B is the secondary radio the receiver of which connects to antenna B. The transmitter in this radio is the standby transmitter. In the event of a radio A active transmitter failure, radio B transmitter becomes active. Antenna B only carries the received signal for Radio B. This antenna is physically separated on the tower by a pre-determined distance from Antenna A. As both radios have a receive path, traffic from the path with the best received bit error rate is routed to the customer interfaces in radio A. In an HSD terminal,  a HSD  Protection Switch Card (PSC) is always fitted in slot H in Radio A and a HSD Protection Interface Card (PIC) is always fitted in slot H in Radio B. The PSC card has a card front switch which controls the hardware setting of the HSD system Active Radio (Auto Select, Radio A or Radio B). Customer  interfaces  are  provided  on  radio  A  only  in  interface  slots  A  to  G.  Interface  connections  to Ethernet and the external alarm inputs and outputs are also provided on radio A only.
 Protected Terminals  |  191  Aprisa XE User Manual  HSD Terminal Cabling The two HSD radios are interconnected as follows:    Cables Supplied with HSD Terminal  The following cables are supplied with a HSD terminal:  RF cable A 110 mm QMA female to QMA female low loss RF cable is required to interconnect between the TX ports of both radio A and radio B. This cable carries the radio B transmitter output to the radio A  transmitter switch.  Ethernet Cable A  200  mm  RJ45  to  RJ45  Ethernet  cable  between  the Ethernet  ports  of  radio A  and radio  B.  This cable carries management IP traffic between radio A and radio B.  Traffic Cable A  200  mm  RJ45  to  RJ45  Ethernet  cable  between  the  PSC  and  PIC.  This  cable  carries  all  user  traffic between Radio A and Radio B.
192  |  Protected Terminals   Aprisa XE User Manual  HSD Terminal IP Addresses Each radio in the HSD link is assigned a unique IP address. All four radios in the HSD link must be on the same subnet. The IP address of the four terminals can only be changed by logging into the relevant radio A or radio B. When the IP addresses have been setup, an ethernet connection to any of the four radios can access all four radios in the HSD link. The usual ethernet connection is to the near end Radio A (see ‘IP Addressing of Terminals’ on page 53).    Example of IP addressing
 Protected Terminals  |  193  Aprisa XE User Manual  Configuring HSD Terminals To  simplify  the  management  and configuration of  the HSD terminals,  SuperVisor  provides  four  windows which display the parameters for all four radios, the local and remote, radios A and B. The HSD System menu item displays the four windows. When a parameter is changed in the four window mode, the relevant parameter is automatically changed to the same setting on the corresponding radio e.g. if a radio A modulation type is changed, the radio B modulation type is also changed to the same setting. The Local and Remote menus continue to display the parameters for the local and remote radios for the near end terminal logged into.    The majority of SuperVisor HSD System pages contain the same parameters and controls as the standard 1+0 XE terminal. The main exceptions are the HSD Control page and the HSD Performance Summary page.
194  |  Protected Terminals   Aprisa XE User Manual  HSD Active Radio Control The HSD system ‘Active Radio’  control determines if the selection of Radio A or Radio B is automatic or manual. This controls both the radio transmitters and receivers. The  Active  Radio  can  be  set  with  the  hardware  switch  on  the  PSC  card  front  or  with  the  SuperVisor software control. The last change of hardware / software control determines the state of the HSD system.  The SuperVisor software control will always reflect the state of the HSD system. After terminal  startup or reboot, the  state of the PSC mode switch determines the setting used by  the system and the SuperVisor software control is set to reflect the state of the HSD system.  The PSC card has two card front LEDs which indicate the status of the HSD system:  PSC Mode Switch Hardware Control Change Software Control Change LED A LED B LED A LED B Radio A Solid Amber Off Flashing Amber Off Auto Select Solid Green Solid Green Flashing Amber Flashing Amber Radio B Off Solid Amber Off Flashing Amber  To set the HSD controls: 1.

 In-Service Commissioning  |  197  Aprisa XE User Manual  12. In-Service Commissioning Before You Start When you have finished installing the hardware, RF and the traffic interface cabling, the system is ready to be commissioned. Commissioning the terminal is a simple process and consists of: 1. Powering up the terminals 2. Configuring both the local and remote terminals using SuperVisor 3. Aligning the antennas 4. Synchronizing the terminals 5. Testing the link is operating correctly. As a minimum, conduct the suggested tests to ensure correct operation.  More  extensive  testing  may  be  required  to  satisfy  the  end  client  or  regulatory  body requirements. 6. Connecting up the client or user interfaces  What You Will Need  Appropriately qualified commissioning staff at both ends of the link.  Safety equipment appropriate for the antenna location at both ends of the link.  Communication equipment, that is, mobile phones or two-way radios.  SuperVisor  software  running on  an  appropriate laptop,  computer, or  workstation  at  one end of  the link.  Tools to facilitate loosening and re-tightening the antenna pan and tilt adjusters.  Predicted  receiver  input  levels  and  fade  margin  figures  from  the  radio  link  budget  (You  can  use Surveyor (see ‘Path planning’ on page 23) to calculate the RSSI, fade margin, and availability).
198  |  In-Service Commissioning   Aprisa XE User Manual  Applying Power to the Terminals   WARNING: Before  applying  power  to  a  terminal,  ensure  you  have  connected  the  safety earth and antenna cable.  Apply power to the terminals at each end of the link.  When power is first applied, all the front panel LEDs will illuminate red for several seconds as the system initializes. After the system is initialized, the OK LED on the front panel should illuminate green and if the terminals are correctly configured, the TX and RX LED should also be illuminated green.  If the RX LED is:  Red the antennas are may be significantly mis-aligned with no signal being received Amber the antennas may be roughly aligned with some signal being received Green the antennas are well-aligned and adequate signal is being received to create a reliable path  If the TX LED is:  Red the transmitter is faulty Amber there is a fault in the antenna connection or feeder cable Green the transmitter is working normally  Review the Link Configurations Using SuperVisor 1. Connect a PC, with SuperVisor installed, to both terminals in the link. 2. Log into the link. 3. Select Link > Summary and confirm the following basic information:  Terminal IP address(es)  Terminal TX and RX frequencies  RSSI (dBm)  TX power (dBm)  SNR (dBm)  Note: If the terminals have not already been configured, refer to ‘Configuring the terminal’ on page 69, ‘Configuring the  traffic  interfaces’  on page  91,  and ‘Configuring the traffic cross connections’  on  page 145.
 In-Service Commissioning  |  199  Aprisa XE User Manual  Antenna Alignment For any point-to-point link, it is important to correctly align the antennas to maximize the signal strength at  both  ends of  the link. Each  antenna must be  pointing  directly  at  the  corresponding  antenna  at the remote site, and they must both be on the same polarization. The antennas are aligned visually, and then small adjustments are made while the link is operating to maximize the received signal. Directional antennas have a radiation pattern that is most sensitive in front of the antenna, in line with the main lobe of the radiation pattern. There are several other lobes (side lobes) that are not as sensitive as the main lobe in front of the antenna.    For the link to operate reliably, it is important that the main lobes of both antennas are aligned. If any of the side lobes are aligned to the opposite antenna, the received signal strength of both terminals will be lower, which  could  result  in  fading.  If  in  doubt,  check  the  radiation  patterns  of  the antennas  you  are using.  Checking the Antenna Polarization Check that the polarization of the antennas at each end of the link is the same. Antenna  polarization  of  grid  antennas are  normally indicated  by  an  arrow  or  with  ‘H’ and  ‘V’  markers (indicating horizontal and vertical). On Yagi antennas, ensure the orientation of the elements are the same at each end of the link.  Transmit frequency and power, and antenna polarization would normally be defined by a regulatory body, and  typically  licensed  to  a  particular  user.  Refer  to  your  license  details  when  setting  the  antenna polarization.
200  |  In-Service Commissioning   Aprisa XE User Manual  Visually Aligning Antennas 1. Stand behind the antenna, and move it from side to side until it is pointing directly at the antenna at the remote site. The remote antenna may be made more visible  by using a mirror, strobe light, or flag.  If  the  remote  end  of  the  link  is  not  visible  (due  to  smoke,  haze,  or  local  clutter,  etc),  align  the antenna by using a magnetic compass. Calculate the bearing using a scale map of the link path.   When setting the antenna on the desired bearing ensure that you use the appropriate true-north to magnetic-north offset. Also ensure that the compass reading is not affected by standing too close to metallic objects.    2. Once the antenna is pointing at the remote antenna, tighten the nuts on the U-bolt or antenna clamp just enough to hold it in position. Leave the nuts loose enough so that small adjustments can still be made. Check that the antenna is still pointing in the correct direction. 3. Move the antenna up or down until it is pointing directly at the remote site. 4. Tighten the elevation and azimuth adjustment clamps. 5. Mark the position of the antenna clamps so that the antenna can be returned to this rough aim point easily when accurately aligning the antennas. 6. Repeat steps 1-5 at the opposite site.  Note: Low gain antennas need less adjustment in elevation as they are simply aimed at the horizon. They should always be panned horizontally to find the peak signal.
 In-Service Commissioning  |  201  Aprisa XE User Manual  Accurately Aligning the Antennas Once  the  antennas  are  visually  aligned,  accurately  align  both  antennas  by  carefully  making  small adjustments while monitoring the RSSI. This will give the best possible link performance.  Note: Remember that it is important to align the main radiation lobes of the two antennas to each other, not any side lobes. It may be easier to perform this procedure if you can communicate with someone at the remote site by telephone, mobile, or two-way radio.  1. Connect a laptop PC running SuperVisor software and power up the terminals at both ends of the link. Select Link > Performance > Summary so that you can see the RSSI indication for the local terminal. Alternatively, use the RSSI test point on the front panel together with a multimeter (see ‘Measuring the RSSI’ on page 202). 2. Move the antenna through a complete sweep horizontally (known as a 'pan') either side of the point established in the visual alignment process above. Note down the RSSI reading for all the peaks in RSSI that you discover in the pan. 3. Move the antenna to the position corresponding to the maximum RSSI value obtained during the pan. Move the antenna horizontally slightly to each side of this maximum to find the two points where the RSSI drops slightly. 4. Move the antenna halfway between these two points and tighten the clamp. 5. If the antenna has an elevation adjustment, move the antenna through a complete sweep (known as a 'tilt') vertically either side of the point established in the visual alignment process above. Note down the RSSI reading for all the peaks in RSSI that you discover in the tilt. 6. Move the antenna to the position corresponding to the maximum RSSI value obtained during the tilt. Move the antenna slightly up and then down from the maximum to find the two points where the RSSI drops slightly. 7. Move the antenna halfway between these two points and tighten the clamp. 8. Recheck the pan (steps 2-4) and tighten all the clamps firmly.    9. Perform steps 1-8 at the remote site.
202  |  In-Service Commissioning   Aprisa XE User Manual  Measuring the RSSI Measure the RSSI value with a multimeter connected to the RSSI test port on the front of the terminal (see ‘Front panel connections and indicators’ on page 31). 1. Insert the positive probe of the multimeter into the RSSI test port, and clip the negative probe to the chassis of the terminal (earth). 2. Pan and tilt the antenna until you get the highest VDC reading. The values shown in the table below relate  the  measured  VDC  to  the  actual  received  signal  level  in  dBm  regardless  of  bandwidth  and frequency.

 In-Service Commissioning  |  203  Aprisa XE User Manual  Checking Performance The  amount  of  testing  performed  on  the  completed  installation  will  depend  on  circumstances.  Some customers may need to prove to a local licensing regulatory body that the link complies with the license provisions.  This  may  require  special telecommunications  test  equipment  to  complete these  tests.  Most customers simply want to confirm that their data traffic is successfully passing over the link, or that the customer interfaces comply with known quality standard. However, the most important performance verification checks are:  Receive input level  Fade margin  Long-term BER  Checking the Receive Input Level The received signal strength at the local terminal is affected by many components in the system and has a direct relationship with the resulting performance of the link. A link operating with a lower than expected signal strength is more likely to suffer from degraded performance during fading conditions. The receive input level of a link is normally symmetrical (that is, similar at both ends). 1. Compare the final RSSI figure obtained after antenna alignment with that calculated for the link. 2. If the RSSI figure is in excess of 3 dB down on the predicted level, recheck and correct problems using the table below and then recheck the RSSI. Alternatively, recheck the link budget calculations.  Possible cause Terminal(s) Is the terminal operating on the correct frequency? Local & remote Is the remote terminal transmit power correct? Remote Are all the coaxial connectors tight? Local & remote Is the antenna the correct type, that is, gain and frequency of operation? Local & remote Is the antenna polarized? Local & remote Is the antenna aligned? Local & remote Is the path between the terminals obstructed?   Note:  If  following  the  above  steps  does  not  resolve  the  situation,  contact  Customer  Support  for assistance.  3. Record the RSSI figure on the commissioning form.  4. Repeat steps 1 to 2 for the other end of the link.
204  |  In-Service Commissioning   Aprisa XE User Manual  Checking the Fade Margin The  fade  margin  is  affected  by  many components in the  system  and  is  closely  related to  the  received signal  strength. A link  operating with  a  lower than  expected  fade margin  is  more  likely to suffer from degraded performance during fading conditions. A reduced fade margin can be due to operating the link too close to the noise floor, or the presence of external interference. The fade margin of a link can be asymmetrical (that is, different at each end). Possible causes of low fade margin are as follows:  Problem Terminal Low receive signal strength (see above table) Local and Remote Interfering signals on the same, or very close to, the frequency of the local terminal receiver. Local Intermodulation products that land on the same or very close to the frequency of the local terminal receiver. Local or Remote Operating near the local receiver noise floor Local  To check the fade margin: 1. Confirm (and correct if necessary) the receive input level (see the previous test). Note: If the receive input level is lower than expected, the fade margin may also be low.  2. Select Link > Performance > Summary and check the current BER of the link in its normal condition is better than 10-6 (If necessary, clear out any extraneous errors by clicking Reset Counters).  3. Check the signal to noise (S/N) indication on the Link > Performance > Summary page. This shows the quality of the signal as it is being processed in the modem. It should typically be better than 30 dB. If it is less than 25 dB, it means that either the RSSI is very low or in-band interference is degrading the S/N performance. 4. Temporarily reduce the remote site's transmit power using either an external attenuator or SuperVisor (Remote > Terminal > Basic). Note: Ideally, the transmit power of the remote site should  be reduced by  up to 20  dB, which  will require  the  use  of  an  external  50  ohm  coaxial  attenuator  capable  of  handling  the  transmit  power involved. In the absence of an attenuator, reduce the transmit power using SuperVisor.  5. Check and note the current BER of the link in its now faded condition (Again, if necessary, clear out any extraneous errors (introduced by the power reduction step above) by clicking Reset Counters). 6. Compare the unfaded and faded BER performance of the link (steps 2 and 4). Continue to reduce the remote transmit power until either the BER drops to 10-6 or the remote transmitter power has been reduced by 20 dB. Note:  The  fade  margin  of  the  link  is  expressed  as  a  number  (of  dB)  that  the  link  can  be  faded (transmitter power reduced) without reducing the BER below operating specifications (1 * 10-6 BER). A 20 dB fade margin is adequate for most links.
 In-Service Commissioning  |  205  Aprisa XE User Manual  7. Record the fade margin and SNR results on the commissioning form. Note: If the transmit power is reduced using SuperVisor rather than an external attenuator, the fade margin should be recorded as ‘Greater than x dB’ (where x = the power reduction).  8. Restore the remote terminal transmit power to normal. 9. Repeat steps 1 to 7 for the other end of the link. Note: If following all the guidelines above does not resolve the situation, contact Customer Support for assistance.  Checking the Long-Term BER The  BER  test  is  a  measure  of  the  stability  of  the  complete  link.  The  BER  results  of  a  link  can  be asymmetrical (that is, different at each end). 1. Select Link > Performance > Summary  and check the current BER and error counters of the  link. If necessary, clear out any extraneous errors by selecting Reset Counters.  2. Wait 15 minutes, and check the BER display and error counters again. If there are a small number of errors and the BER is still better than 1 x 10-9, continue the test for 24 hours. If there are a significant number of errors, rectify the cause before completing the 24 hour test. Note: It is normal to conduct the BER test in both directions at the same time, and it is important that no further work be carried out on the equipment (including the antenna) during this period.  3. The BER after the 24 hour test should typically be better than 1 x 10-8. 4. Record the BER results on the commissioning form.  Bit Error Rate Tests A Bit Error Rate (BER) test can be conducted on the bench, (see ‘Bench Setup’ on page 43). Attach the BER tester to the interface port(s) of one terminal, and either another BER tester or a loopback plug to the corresponding interface port of the other terminal.  This BER test can be carried out over the Ethernet, E1 / T1, V.24 or HSS interfaces. It will test the link quality with regard to user payload data. CAUTION: Do not apply signals greater than -20 dBm to the antenna as they can damage the receiver. In a bench setup, there must be 60 - 80 dB at up to 2 GHz of 50 ohm coaxial attenuation (capable of handling the transmit power) between the terminals’ antenna connectors.

 Maintenance  |  213  Aprisa XE User Manual  13. Maintenance There are no user-serviceable components within the terminal. All hardware maintenance must be completed by 4RF or an authorized service centre. Do not attempt to carry out repairs to any boards or parts. Return all faulty terminals to 4RF or an authorized service centre.  For more information on maintenance and training, please contact Customer Services.  CAUTION: Electro Static Discharge (ESD) can damage or destroy the sensitive electrical components in the terminal.  Routine Maintenance Every six or twelve months, for both ends of the link, you should record the RSSI and SNR levels as well as checking the following: Item What to check or look for Equipment shelter environment Water leaks Room temperature Excessive vibration Vermin damage Terminal mounting Firmly mounted Antenna cable connections Tight and dry Antenna cable and its supports Not loose or suffering from ultra-violet degradation Antenna and its mounting hardware Not loose, rusty or damaged Safety earth Connections tight Cabling intact DC system Connections tight Voltage in normal limits Batteries (if installed) Connections tight Electrolyte levels normal
214  |  Maintenance   Aprisa XE User Manual  Terminal Upgrades You  can  upgrade  all  software  for  both  terminals  remotely  (through  a  management  network),  which eliminates the need to physically visit either end of the link. A terminal is upgraded by accessing a running TFTP server (see ‘TFTP Upgrade Process’ on page 221). All the  required  files  are  uploaded  from the  TFTP server  into  the terminal and  then  activated  following a terminal reboot. System files can be manually uploaded (see ‘Uploading System Files’ on page 226‘). Inventory File Software release 8.2.10 and all future software releases, contains an inventory file (similar to a manifest file) which is used to validate the software files in the terminal. To view the Software Status of the terminal: Select Link, Local or Remote > Summary  Software status Function Standard Software Release The software status indicates ‘Standard Software Release’ if the following system software files have not been changed since the last TFTP Upgrade.  Kernel image file  Software image file  Firmware image files  Configuration files Modified Software Release The software status indicates ‘Modified Software Release’ if the system software files have been changed since the last TFTP Upgrade. This could be caused by:  an image file which has been uploaded to the terminal since the last TFTP upgrade which is not part of that upgrade.   an image file which was part of  the last TFTP upgrade but was subsequently deleted.  Upgrade Prerequisites To minimize disruption of link traffic and prevent your terminals from being rendered inoperative, please follow the  procedures described  in  this section together with any additional information or instructions supplied with the upgrade package. Before  upgrading  the  terminal,  ensure  that  you  have  saved  the  configuration  file  (see  ‘Saving  the terminal's  configuration’  on  page  89)  as  well  as  the  cross  connection  configuration  (see  ‘Saving  cross connection configurations’ on page 155). The  Remote  terminal  upgrade  process  will  be  faster  if  the  bandwidth  allocated  to  the  management ethernet capacity is maximized. The terminal software must be identical at both ends of the link. At the end of the terminal upgrade process, the versions of image files (kernel software, and firmware) that were in use before the upgrade are still in the terminal. You can restore them, if required, by editing the image tables and reactivating the old files (see ‘Changing the Status of an Image ’ on page 232).  IMPORTANT  NOTE:  Ensure  you  are  logged  into  the  Near  end  terminal  as  Admin  before  you  start  an upgrade.
 Maintenance  |  215  Aprisa XE User Manual  Software Upgrade Process  Unzip and save the following folders to your hard drive:  8.6.77 Software  tftpd32.exe The following steps are required for the software upgrade process: 1.

 Maintenance  |  217  Aprisa XE User Manual  Identifying the Correct TFTP Upgrade Type  The  correct  TFTP  upgrade  type  will  depend  on  both  the  Bootloader  Version  and  the  Software  Version Type. Aprisa XE terminals running the older bootloader software (bootloader version 0) have a limitation on the number of software images that can be loaded simultaneously into a terminal.  Identifying the Bootloader Version Determine  which  bootloader  version  your  terminal  is  running  by  using  the  SuperVisor  menu  item Maintenance > Support Summary and look for the ‘Bootloader Version’ number:  (1)  If your terminal is running bootloader version 1 or greater, use the TFTP full upgrade process. (2)  If your terminal is running bootloader version 0 and running a software version prior to 7.0.6, use the TFTP partial upgrade process. (3)  If your terminal is running bootloader version 0 and running a software version 7.0.6 or later, use the TFTP standard upgrade process. (4)  HSD terminals cannot run with bootloader version 0.
218  |  Maintenance   Aprisa XE User Manual  Identifying the Software Version Type  There are six different software version types; ETSI type 1, ETSI type 1 HSD, ETSI type 2, ETSI type 2 HSD, FCC Part 101 and FCC Part 90.

226  |  Maintenance   Aprisa XE User Manual  Uploading System Files  System files e.g. configuration files, kernel image files, software image files and firmware image files can be uploaded manually.  Note: You should only upgrade components that need changing. It is not always necessary, for instance, to replace kernel or software files when upgrading a single firmware file. If interdependency exists between file types, this will be made clear in the documentation that accompanied the update package.  Configuration Files Configuration files (.cfg) are compressed archives containing a script to instruct the terminal on how to handle the other files in the archive. Uploading  of  configuration  files  can  only  be  performed  to  the  Local  Terminal  (not  via  the  link  to  the Remote Terminal).  RF synthesizer configuration files The RF synthesizer configuration archive contains files that provide values for the transmitter and receiver synthesizers to operate across the supported frequency bands. Synthesizer configuration filenames have the following format:  XE_(frequency bands)_synth.cfg e.g. XE_300_400_synth.cfg  Modem configuration files The  Modem  configuration  archive  contains  files  that  provide  values  for  the  Modem  to  operate  at  the various supported channel sizes and modulation types. Modem configuration filenames have the following format:  modem_(version number).cfg e.g. modem_8_3_1.cfg (ETSI variants)  Cross-connect configuration files The Cross-connect configuration archive contains the Cross Connections application program that can be launched from within SuperVisor. Cross-connect configuration filenames have the following format:  C-crossconnect_(version number).cfg e.g. C-crossconnect_8_6_7.cfg

Browse to the location of the file required to be uploaded into the terminal *.cfg. 3. Click on Upload.    The normal response is Succeeded if the file has been loaded correctly. A response of ‘Failed’ could be caused by:  Not enough temporary space in the filesystem to uncompress the archive and execute the script  A file or directory expected by the script not being present on the filesystem  4. Reboot the terminal using a ‘Hard Reboot’ (see ‘Rebooting the Terminal’ on page 233).
228  |  Maintenance   Aprisa XE User Manual  Image Files  Image files (.img) are loaded into the terminal and either contains code that is executed by the system processor, or contain instructions to configure the various programmable logic elements. The image file types that can be uploaded are:  Kernel image files  Software image files  Firmware image files  Note: The  Bootloader image file C-CC-B-(version  number).srec and Flash File System image file C-CC-F-(version number).img can only be changed in the factory.  Uploading  of  image  files  can  only  be  performed  to  the  local  terminal  (not  via  the  link  to  the  remote terminal).  To upload and activate an image file: 1. Upload the required image file. If the Upload Status page show ‘executing’, then ‘writing to flash’, then ‘Succeeded’, then the file has been written into the image table correctly.    If the Upload Status is ‘Failed’, there may not be enough free space in the image table to write the file. Inactive images can be deleted (and the terminal rebooted) to free up space for the new image (see ‘Changing the Status of an Image File’ on page 232).  2. Set the status of the image to ‘activate’ (see ‘Changing the Status of an Image ’ on page 232). This actually sets the status to ‘Selected’ until after a terminal reboot. 3. Reboot the terminal using a ‘Hard Reboot’ (see ‘Rebooting the Terminal’ on page 233). This activates the selected image. The image table status will now show ‘Active’. The previous image file status will now show as ‘Inactive’.

 Troubleshooting  |  241  Aprisa XE User Manual  14. Troubleshooting Loopbacks Loopbacks are used as a tool for testing or as part of the commissioning process and will affect customer traffic across the link. The terminal supports three types of loopbacks:   RF radio loopback  Interface loopbacks, set at the interface ports  Timeslot loopbacks  RF Radio Loopback The RF radio loopback provides a loopback connection between the radio TX and radio RX. Each terminal is looped back independently.    All traffic entering the transmit stage of the transceiver is transmitted on the RF link but is also looped back to the receiver section of the transceiver. This loopback will affect all traffic through the terminal. When the RF loopback is activated, both the radio RX and TX LEDs will flash. An RF loopback will automatically deactivate after the period set (in seconds) in the RF Loopback Timeout field. The default entry is 3600 seconds (60 minutes). When an RF loopback is activated, the ethernet path is disabled to prevent ethernet loopbacks. An RF loopback is deactivated if the terminal is rebooted.  To activate or deactivate the RF loopback: Select Link or Local or Remote > Maintenance > Loopbacks.    To activate the RF loopback, tick the RF Loopback checkbox. Untick the checkbox to deactivate it. Click Apply to apply changes or Reset to restore the previous configuration.
242  |  Troubleshooting   Aprisa XE User Manual  Interface Loopbacks The interface loopback provides a loopback connection for the customer-connected equipment. These loopbacks are applied on a port-by-port basis and can only be enabled on active ports i.e. the port has to be activated by assigning traffic to it by the Cross Connections application. These are two types of interface loopbacks: Line Facing – port traffic from the customer is transmitted over the RF link but is also looped back to the customer    Radio Facing – traffic received from the RF link is passed to the customer port but is also looped back to be transmitted over the RF link.    Loopback type Description QJET (whole tributary) The QJET interface port has both Line Facing and Radio Facing loopbacks (see ‘QJET Port Settings’ on page 102). The interface card green LED flashes while the loopback is active. QJET (individual timeslot) The Cross Connections application can loopback framed E1 / T1 timeslots (see ‘Timeslot Loopbacks’ on page 243).  Q4EM port The Q4EM interface port has both Line Facing and Radio Facing loopbacks (see ‘Q4EM Port Settings’ on page 104). The interface card yellow LED flashes while the loopback is active. DFXO port The DFXO interface Line Facing loopback loops back the port data to the customer. This loopback is performed on the digital path of the codec. The interface card yellow LED flashes while the loopback is active. DFXS port The DFXS interface Line Facing loopback loops back the port data to the customer. This loopback is performed on the digital path of the codec. The interface card yellow LED flashes while the loopback is active. HSS port The HSS interface Line Facing loopback loops back the port data to the customer. The interface card top green LED flashes while the loopback is active. QV24 port The QV24 interface Line Facing loopback will loop back the port data to the customer. Ethernet No loopback possible.

Loss Of Frame alignment (LOF) A loss of frame alignment alarm occurs when the E1  / T1 interface RX input receives a valid G.703 signal (code and frequency) but does not receive a valid G.704 signal i.e. no frame alignment word, from the downstream system (in framed E1 / T1 modes only) (red alarm in framed T1 modes). This alarm masks the AIS received alarm.   Alarm Indication Signal (AIS) An AIS received alarm occurs when AIS is received from the downstream system. An E1 / T1 interface will output AIS to the downstream system if the normal upstream traffic signal is not  available  e.g.  loss  of  modem  synchronization,  loss  of  RF  signal  across  the  link  (blue  alarm  in framed T1 modes).    Remote Alarm Indicator (RAI) A remote alarm indicator occurs when RAI  is received  from the downstream system when it has an active LOS or LOF alarm (TS0 NFAS bit 3 in framed E1 modes and yellow alarm in framed T1 modes).   TS16 Loss of signal (TS16LOS) A TS16 loss of signal alarm occurs when there is no valid TS16 signal at the E1 interface RX input from the downstream system (in E1 PCM 30 modes only).   TS16 Remote Multi-frame Alarm Indicator (RMAI) A remote multiframe alarm indicator occurs when RMAI is received from the downstream system when it has an active TS16LOS alarm  (TS16 F0 bit 6 in E1 PCM 30 modes only).   TS16 Alarm Indication Signal (TS16AIS) A TS16 Alarm Indication Signal alarm occurs when AIS is received from the downstream system in TS16. An E1 interface will output the TS16 AIS signal to the downstream system if the normal TS16 multi-frame signal is not available  (in E1 PCM 30 modes only).  The QJET interface green LED indicates: The QJET interface green LED flashes when the E1 / T1 port loopback is active.
 Troubleshooting  |  253  Aprisa XE User Manual  System Log  SuperVisor automatically keeps a log, known as 'syslog', which captures all alarms, errors and events for each terminal.  You can specify that the ‘syslog’ is saved to a particular file (see ‘Setting up for Remote Logging’ on page 255). You can then email this file to  customer service, if requested, to enable them to fault-find more accurately. Checking the Syslog To view the Syslog: 1. Select Local > Performance > Logging > Syslog. This opens a new window:
254  |  Troubleshooting   Aprisa XE User Manual  2. The system log is quite hard to decipher in Internet Explorer. If you're using Internet Explorer, select View > Source, which opens the file  in  a more legible layout in  Notepad.  Save or print this file, as required.    3. If you want to save the system log, you can save it from within Notepad (or Internet Explorer). Select File > Save As. Navigate to where you want to save the file. Enter a meaningful filename and select 'Text File' from the Save As Type drop-down list. Click Save.  You can specify that this file is automatically saved to a computer (see ‘Setting up for Remote Logging’ on page 255).
 Troubleshooting  |  255  Aprisa XE User Manual  Setting up for Remote Logging Note: When setting up to save the system log to a specific computer, be aware that the file is constantly updated and may get quite large quite quickly.  To set up a terminal for remote logging: 1. Copy  the  TFTP  server  application  (tftpd32.exe,  which  is  located  in  the  TFTPD  directory)  from  the terminal product CD into a suitable directory on the PC (for example, C:\Program Files\TFTP Server). 2. Create another directory where you want the system logs to be saved for example; C:\Aprisa XE Syslog 3. Double-click tftpd32.exe.    4. Click Settings and make sure that both ‘Syslog Server’ and ‘Save syslog message’ boxes are ticked.    5. Click Browse and select a directory where you want the Syslog file to be saved (created in step 2).  6. Click OK to close the Settings dialog box.
256  |  Troubleshooting   Aprisa XE User Manual  7. In SuperVisor, select Link or Link or Local or Remote > Terminal > Advanced.    8. In  the  Remote  Syslog  Address  field,  enter  the  IP  address  of  the  PC  on  which  the  Syslog  server  is running.  9. In the Remote Syslog Port field, enter 514.  10. Reboot the terminal (Link or Local or Remote > Maintenance > Reboot).   11. Open the directory where the system logs are being saved to. You should see a file called syslog.txt.

 Product End Of Life  |  317  Aprisa XE User Manual  19. Product End Of Life End-of-Life Recycling Programme (WEEE) The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment. Under the Directive, used equipment must be marked, collected separately, and disposed of properly. 4RF Limited  has  implemented an  end-of-life  recycling  programme to  manage the  reuse,  recycling, and recovery of waste in an environmentally safe manner using processes that comply with the WEEE Directive (EU Waste Electrical and Electronic Equipment 2002/96/EC).  The WEEE Symbol Explained  This  symbol  appears  on  Electrical  and  Electronic  Equipment  (EEE)  as  part  of  the  WEEE  (Waste  EEE) directive. It  means that the EEE may contain hazardous  substances  and must  not be thrown away  with municipal or other waste.  WEEE Must Be Collected Separately You  must  not  dispose  of  electrical  and  electronic  waste  with  municipal  and  other  waste.  You  must separate it from other waste and recycling so that it can be easily collected by the proper regional WEEE collection system in your area.  YOUR ROLE in the Recovery of WEEE By separately collecting and properly disposing of WEEE, you are helping to reduce the amount of WEEE that enters the waste stream. One  of  the  aims  of  the  WEEE  directive  is  to  divert  EEE  away  from  landfill  and  encourage  recycling. Recycling EEE means that valuable resources such as metals and other materials (which require energy to source and manufacture) are not wasted. Also, the pollution associated with accessing new materials and manufacturing new products is reduced.  EEE Waste Impacts the Environment and Health Electrical and electronic equipment (EEE) contains hazardous substances which have potential effects on the  environment  and human health.  If you  want  environmental information  on the  Aprisa  XE  terminal, contact us (on page 19).
