Prestige 964 Cable Router with 802.11g Access Point Getting to Know Your P964 APR 1-1 Chapter 1 Getting to Know Your P964 APR This chapter provides functional overviews, key features, applications and product specifications of your P964 APR 1.1 Overview of the P964 APR The P964 APR is a high bandwidth Internet access Cable Modem with integrated router device that connects your home/office LAN to the Internet using the hybrid fiber coaxial (HFC) cable; the same cable that brings television into a cable television (CATV) subscriber’s home. Through 4 Ethernet and 1 USB ports of the P964 APR , up to 5 computers and can be directly connected to the HFC cable network for high-speed access to the Internet without an external Ethernet hub. Ideally, It allows 253 computer users using the same cable to access the internet. P964 APR provides model for supporting the Multimedia Cable Network System (MCNS) Data Over Cable Service Interface Specification (DOCSIS) specifications in 1.0/1.1/2.0 version. MCNS is a consortium of cable television companies whose goal is to create standards for interoperable data-over-cable systems. The P964 APR is powered by one external 9V DC-input power supply. 1.2 Hardware Interfaces P964 APR has integrated 4-port Ethernet switch and one USB 1.1 interfaces concurrently. The 4-port switch provides auto crossover MDI/MDI-x function and is 10/100M bps Ethernet auto-negotiating. The physical user interfaces of P964 APR provide you with the capability of wired connecting up to 5 stations without the need of external Ethernet hub/switch. If you have more than 5 wired computers, to choose a hub/switch can easily expand the number of LAN users. P964 APR is designed for wired and wireless computer users. The P964 APR is also equipped with a reset button which is used for user to reset the device to factory default user name and password of each user interfaces. Hold on the Reset button for 10 seconds, the user name and password will return to the factory default and the P964 APR will automatically reboot. Press the reset button will also make system reboot while P964 APR is not working properly. 1.3 Firmware Operation Mode According to DOCSIS specification, a cable modem is basically a bridge device. It can be configured to serve specific CPEs by provisioning their MAC addresses. Only traffic to/from these CPEs will be forwarded. The others will be filtered. It can also be configured to serve specific numbers of CPEs. However, these services are provided by your cable operator. They have to setup one account for each CPE. For most Internet users, they have only one access account. If they have two computers' at home and want to share this account for two or more users, they have to add another Internet sharing device, like a router. The P964 APR is equivalent to a cable modem plus a router with the capability of wireless data access. This is very suitable for SOHO and SME for Internet sharing.
Prestige 964 Cable Router with wireless Access Point 1-2 Getting to Know Your P964 APR P964 APR has three major operation modes as shown in Figure 1-1. Figure 1-1 Prestige 964 Operation Mode 1.3.1 Bridge Mode In Bridge mode, P964 APR operates just like a normal cable modem/router. All operation is compliant to DOCSIS specifications. 1.3.2 IP Sharing Mode In IP Sharing mode, the P964 APR operates as a NAT router. It requires one public IP address from MSO’s DHCP pool and provides private IP address space for LAN users. The public IP can be static assigned or dynamically assigned through DHCP. 1.3.3 Static IP Mode In Static IP mode, P964 APR provide a routed subnet on its Ethernet interface. A public IP subnet can be assigned at the Ethernet interface such that the end user can have a static assigned subnet. At the same time, the LAN users can also use private IP addresses to get on Internet.

Prestige 964 Cable Router with 802.11g Access Point Getting to Know Your P964 APR 1-3 1.4 Key Features of the P964 APR The following are the key features of the P964 APR: DOCSIS 1.0/1.1/2.0 Compliant cable modem Provides interoperability with other DOCSIS compliant cable modems and cable headend equipment. Peak downstream signaling rates of 38Mbps and upstream signaling rates of 30 Mbps Access the Internet with high performance network capability. DOCSIS cable systems are capable of providing signaling rate of up to 43/55 Mbps and 30 Mbps for downstream and upstream respectively. This bandwidth however, is shared by several subscribers because there are very few computers today that can connect to a network at such high speeds. Hence, typical connection speeds are 5 Mbps downstream and 1 Mbps upstream. IP routing, TCP, ICMP, ARP, TFTP, RIP1, RIP2 with MD5 Improves network performance through containment of broadcast messages and improves security support for unicast, broadcast and multicast IP packets. The RIP supports key-string encrypted with MD5 for authentication with the CMTS. 4-port Auto-negotiating and Auto MDI/MDI-X 10/100 Mbps Ethernet Switch The 4-port LAN interface automatically detects if it is on a 10 Mbps or a 100 Mbps Ethernet. 56-bit DES Baseline Privacy Software Remotely Upgradeable The software and configuration information is downloadable from the cable headend to the Prestige. This eliminates the need for a cable technician's visit to install software upgrades. Upgrade P964 APR Firmware via LAN The firmware of the P964 APR can be upgraded via the LAN. Built-in Diagnostic Features P964 APR support remote troubleshooting via CMTS-initiated diagnostics, eliminating visit by a technician. The front panel status indicator LEDs and web based status monitoring are also incorporated to easy diagnostics from LAN interfaces. SNMP SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information between network devices. SNMP is a member of TCP/IP protocol suite. Your P964 APR supports SNMP agent functionality, which allows a manager station to manage and monitor the P964 APR through the network. The P964 APR supports SNMP version one, two and three.(SNMP v1, v2 and v3). Network Address Translation (NAT) NAT (Network Address Translation - NAT, RFC 1631) allows the translation of an Internet Protocol address used within one network to a different IP address known within another network. DHCP (Dynamic Host Configuration Protocol) DHCP (Dynamic Host Configuration Protocol) allows the individual client computers to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server capability,
Prestige 964 Cable Router with wireless Access Point 1-4 Getting to Know Your P964 APR enabled by default, which means it can assign IP addresses, an IP default gateway and DNS servers to all systems that support the DHCP client.

Step 2. Connecting the P964 APR to the Cable System Connect the P964 APR to the cable port using an F-type connector. (If the quality or general condition of the coaxial cable at the installation site is in question, we recommended that you replace the coaxial cable). The cable port on the P964 APR is labeled "CABLE”. Step 3. Connecting Ethernet Cable(s) or USB cable to the P964 APR If you do not have an Ethernet interface card (NIC) in your computer, please install one or use the USB connectivity. The Ethernet interface of your P964 APR support 10/100M auto-negotiating and auto MDI/MDI-X function. You can use any type of Ethernet cable to connect it to your computer directly or through an external switch/hub. Step 4. Connecting the Power Adapter to your P964 APR Connect the power adapter to the port labeled POWER on the rear panel of your P964 APR. Step 5. P964 APR Initialization The P964 APR is powered on whenever you connect the power adapter to the power outlet. It will initialize the system and start to connect with headend CMTS. When the CABLE LED shines steadily, the P964 APR is ready to handle data traffic. The first initialization process might take several minutes because it will scan for the proper downstream and upstream channels. When the P964 APR is ready, it will memorize the channel attributes. If you power cycle the P964 APR, the next connection process will be faster. 2.5 Network Configuration of Your Computer You must have a network interface card installed on your computer and configure the TCP/IP protocol stack properly. For Windows® 95/98/NT/2000, please configure your computer as a DHCP client. The IP address identifies the computer on the network and enables the headend CMTS to route data to and from your computer. For Windows® 95/98, you can use the following command to verify the TCP/IP configuration. Winipcfg For Windows® NT/XP/2000, you can use the following command to verify the TCP/IP configuration. Ipconfig
P964 APR Cable Router with 802.11g Access Point Hardware Installation 2-7 2.6 Router Configuration You do not need to ask your cable company for a special configuration. The P964 APR can act as a DHCP client to acquire an IP address from the headend. Besides, it can act as a DHCP server at the LAN port and assign an IP address to your computers on the LAN subnet. What you have to do is to configure the LAN port with the proper IP address and netmask. If you already have a DHCP server on your LAN subnet, you can disable the DHCP server in the P964 APR but you have to assign an IP address/netmask for the LAN port. 2.7 Power On Your P964 APR You should connect at least one of the LAN,USB port to your computer. Connect the cable port and the power port to the appropriate devices . Plug the power adapter into a wall outlet When connected, it is powered on, the P964 APR executes an automatic installation procedure: 1. Scans and locks on to the service provider’s downstream frequency. 2. Obtains timing, signal, power level, authentication, addressing, and other operational parameters from the headend CMTS. 3. Downloads its configuration file and is then operational. During the initialization, the LEDs on the P964 APR turns on: 1. The Power LED should be ON. 2. The CABLE LED will flash with a 2 seconds duration while scanning the downstream channel. When it has locked on to a downstream channel and is communicating with the headend CMTS, the CABLE LED will flash with a 1 second duration. Once the cable connection is completed, it will remain “ON”. It may need 40 seconds from step 1 to step 2.. 3. The DATA LED flashes when the P964 APR is receiving or transmitting data through the coaxial cable. It is OFF when no data is transferred. 4. Depending on which port is connected successfully, the LAN (1~4) LED , WLAN, or the USB LED will be “ON” and flashing while sending/receiving data to/from your computer/laptop. After the initial setup and P964 APR is powered on, you can modify the configuration remotely through telnet connections.

Cryptoanalysis The act of analyzing (or breaking into) secure documents or systems that are protected with encryption. CSU/DSU Channel Service Unit/Data Service Unit. CSUs (channel service units) and DSUs (data service units) are actually two separate devices, but they are used in conjunction and often combined into the same box. The devices are part of the hardware you need to connect computer equipment to digital transmission lines. The Channel Service Unit device connects with the digital communication line and provides a termination for the digital signal. The Data Service Unit device, sometimes called a digital service unit, is the hardware component you need to transmit digital data over the hardware channel. The device converts signals from bridges, routers, and multiplexors into the bipolar digital signals used by the digital lines. Multiplexors mix voice signals and data on the same line. DCE Data Communications Equipment is typically a modem or other type of communication device. The DCE sits between the DTE (data terminal equipment) and a transmission circuit such as a phone line. Decryption The act of restoring an encrypted file to its original state. Denial of Service Act of preventing customers, users, clients or other machines from accessing data on a computer. This is usually accomplished by interrupting or overwhelming the computer with bad or excessive information requests. DHCP Dynamic Host Configuration Protocolautomatically assigns IP addresses to clients when they
P964 APR Cable Router with 802.11g Access Point Glossary G log on. DHCP centralizes IP address management on central computers that run the DHCP server program. DHCP leases addresses for a period of time which means that addresses are made available to assign to other systems. Digital Signature Digital code that authenticates whomever signed the document or software. Software, messages, Email, and other electronic documents can be signed electronically so that they cannot be altered by anyone else. If someone alters a signed document, the signature is no longer valid. Digital signatures are created when someone generates a hash from a message, then encrypts and sends both the hash and the message to the intended recipient. The recipient decrypts the hash and original message, makes a new hash on the message itself, and compares the new hash with the old one. If the hashes are the same, the recipient knows that the message has not been changed. Also see Public-key encryption. DNS Domain Name System. A database of domain names and their IP addresses. DNS is the primary naming system for many distributed networks, including the Internet. DOCSIS Data over Cable Service Interface Specification. It is the dominating cable modem standard, which defines technical specifications for both cable modem and CMTS. Domain Name The unique name that identifies an Internet site. Domain Names always have 2 or more parts, separated by dots. The part on the left is the most specific, and the part on the right is the most general. Downstream The data flowing from the CMTS to the cable modem. Downstream Frequency The frequency used for transmitting data from the CMTS to the cable modem. Normally in the 42/65-850 MHz range depending on the actual cable plant capabilities. DRAM Dynamic RAM that stores information in capacitors that must be refreshed periodically. DTE Originally, the DTE (data terminal equipment) meant a dumb terminal or printer, but today it is a computer, or a bridge or router that interconnects local area networks. EMI ElectroMagnetic Interference. The interference by electromagnetic signals that can cause reduced data integrity and increased error rates on transmission channels. Encryption The act of substituting numbers and characters in a file so that the file is unreadable until it is decrypted. Encryption is usually done using a mathematical formula that determines how the file is decrypted. Ethernet A very common method of networking computers in a LAN. There are a number of adaptations to the IEEE 802.3 Ethernet standard, including adaptations with data rates of 10 Mbits/sec and 100 Mbits/sec over coaxial cable, twisted-pair cable, and fiber-optic cable. The latest version of Ethernet, Gigabit Ethernet, has a data rate of 1 Gbit/sec. Events These are network activities. Some activities are direct attacks on your system, while others might be depending on the circumstances. Therefore, any activity, regardless of severity is called an event. An event may or may not be a direct attack on your system. FAQ (Frequently Asked Questions) -- FAQs are documents that list and answer the most common questions on a particular subject. FCC The FCC (Federal Communications Commission) is in charge of allocating the electromagnetic spectrum and thus the bandwidth of various communication systems. Firewall A hardware or software "wall" that restricts access in and out of a network. Firewalls are most often used to separate an internal LAN or WAN from the Internet.
P964 APR Cable Sharing Gateway with 4-port Switch H Glossary Flash memory The nonvolatile storage that can be electrically erased and reprogrammed so that data can be stored, booted, and rewritten as necessary. FTP File Transfer Protocol is an Internet file transfer service that operates on the Internet and over TCP/IP networks. FTP is basically a client/server protocol in which a system running the FTP server accepts commands from a system running an FTP client. The service allows users to send commands to the server for uploading and downloading files. FTP is popular on the Internet because it allows for speedy transfer of large files between two systems. Gateway A gateway is a computer system or other device that acts as a translator between two systems that do not use the same communication protocols, data formatting structures, languages, and/or architecture. Hacker Generally, a hacker is anyone who enjoys experimenting with technology including computers and networks. Not all hackers are criminals breaking into systems. Some are legitimate users and hobbyists. Nevertheless, some are dedicated criminals or vandals. HDLC HDLC (High-level Data Link Control) is a bit-oriented (the data is monitored bit by bit), link layer protocol for the transmission of data over synchronous networks. Headend Central distribution point for a CATV system. Video signals are received here from satellites and maybe other sources, frequency converted to the appropriate channels combined with locally originated signals and rebroadcast onto the HFC plant. The headend is where the CMTS is normally located. HFC HFC (hybrid fiber coaxial cable) is a telecommunication technology in which fiber optic cable and coaxial cable are used in different portions of a network to carry broadband content (such as video, data and voice). Typically, a local cable TV company might use fiber optic cable from the cable headend (distribution center) to serving nodes located close to business and residential users and from these nodes use coaxial cable to individual businesses and homes. An advantage of HFC is that some of the characteristics of fiber optic cable (high bandwidth and low noise and interference susceptibility) can be brought close to the user without having to replace the existing coaxial cable that is installed all the way to the home and business. Host Any computer on a network that is a repository for services available to other computers on the network. It is quite common to have one host machine provide several services, such as WWW and USENET. HTTP Hyper Text Transfer Protocol. The most common protocol used on the Internet. HTTP is the primary protocol used for web sites and web browsers. It is also prone to certain kinds of attacks.IANA Internet Assigned Number Authority acts as the clearinghouse to assign and coordinate the use of numerous Internet protocol parameters such as Internet addresses, domain names, protocol numbers, and more. The IANA Web site is at http://www.isi.edu/iana. ICMP Internet Control Message Protocol is a message control and error-reporting protocol between a host server and a gateway to the Internet. ICMP uses Internet Protocol (IP) datagrams, but the messages are processed by the TCP/IP software and are not directly apparent to the application user. Integrity Proof that the data is the same as originally intended. Unauthorized software or people have not altered the original information. internet (Lower case i) Any time you connect 2 or more networks together, you have an internet. Internet (Upper case I) The vast collection of inter-connected networks that all use theTCP/IPprotocols
P964 APR Cable Router with 802.11g Access Point Glossary I and that evolved from the ARPANET of the late 60’s and early 70’s. The Internet now (July 1995) connects roughly 60,000 independent networks into a vast global internet Internet Worm See Worm. Intranet A private network inside a company or organization that uses the same kinds of software that you would find on the public Internet, but that is only for internal use. Intruder Person or software interested in breaking computer security to access, modify, or damage data. Also see Cracker. IP Internet Protocol, is the underlying protocol for routing packets on the Internet and other TCP/IP-based networks. IPCP (PPP) IP Control Protocol allows changes to IP parameters such as the IP address. IPX Internetwork Packet eXchange The native NetWare internetworking protocol is IPX (Internetwork Packet Exchange). Like IP (Internet Protocol), IPX is an internetworking protocol that provides datagram services. IRC Internet Relay Chat. IRC was developed in the late 1980s as a way for multiple users on a system to “chat” over the network. Today IRC is a very popular way to “talk” in real time with other people on the Internet. However, IRC is also one avenue hackers use to get information from you about your system and your company. Moreover, IRC sessions are prone to numerous attacks that while not dangerous can cause your system to crash. ISP Internet Service Providers provide connections into the Internet for home users and businesses. There are local, regional, national, and global ISPs. You can think of local ISPs as the gatekeepers into the Internet. LAN Local Area Network is a shared communication system to which many computers are attached. A LAN, as its name implies, is limited to a local area. This has to do more with the electrical characteristics of the medium than the fact that many early LANs were designed for departments, although the latter accurately describes a LAN as well. LANs have different topologies, the most common being the linear bus and the star configuration. Linux A version of the UNIX operating system designed to run on IBM Compatible computers. Logic Bomb A virus that only activates itself when certain conditions are met. Logic bombs usually damage files or cause other serious problems when they are activated. MAC On a local area network (LAN) or other network, the MAC (Media Access Control) address is your computer's unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.) The MAC layer frames data for transmission over the network, then passes the frame to the physical layer interface where it is transmitted as a stream of bits. MCNS Multimedia Cable Network System is the consortium behind the DOCSIS standard for cable modems. MSO Multiple Service Operators. A cable TV service provider that also provides other services such as data and/or voice telephony. Name Resolution The allocation of an IP address to a host name. See DNS NAT Network Address Translation is the translation of an Internet Protocol address used within one network to a different IP address known within another network - see also SUA. NDIS Network Driver Interface Specification is a Windows specification for how communication protocol programs (such as TCP/IP) and network device drivers should communicate with each other.
P964 APR Cable Sharing Gateway with 4-port Switch J Glossary NetBIOS Network Basic Input / Output System. NetBIOS is an extension of the DOS BIOS that enables a PC to connect to and communicate with a LAN. Network Any time you connect 2 or more computers together so that they can share resources, you have a computer network. Connect 2 or more networks together and you have an internet. NIC Network Interface Card. A board that provides network communication capabilities to and from a computer system. Also called an adapter. Node Any single computer connected to a network One-way Cable Modem A one-way Cable Modem uses the TV cable for the downstream (receive) and a telephone modem for upstream (transmit). PAC The box that calls/answers the phone call and relays the PPP frames to the PNS. A PAC must have IP and dial-up capability. Packet Filter A filter that scans packets and decides whether to let them through. PAP Password Authentication Protocol PAP is a security protocol that requires users to enter a password before accessing a secure system. The user’s name and password are sent over the wire to a server, where they are compared with a database of user account names and passwords. This technique is vulnerable to wiretapping (eavesdropping) because the password can be captured and used by someone to log onto the system. Password Cracker A program that uses a dictionary of words, phrases, names, etc. to guess a password. Password encryption A system of encrypting electronic files using a single key or password. Anyone who knows the password can decrypt the file. Password Shadowing The encrypted password is no visible in the passwd file but stored in a shadow file that is only readable by root. This prevents brute force attacks on the encrypted field to guess the password. see e.g.: http://whatis.com/shadowpa.htm Penetration Gaining access to computers or networks by bypassing security programs and passwords. Phreaking Breaking into phone or other communication systems. Phreaking sites on the Internet are popular among crackers and other criminals Ping Attack An attack that slows down the network until it is unusable. The attacker sends a "ping" command to the network repeatedly to slow it down. See also Denial of Service. Pirate Someone who steals or distributes software without paying the legitimate owner for it. This category of computer criminal includes several different types of illegal activities Making copies of software for others to use. Distributing pirated software over the Internet or a Bulletin Board System. Receiving or downloading illegal copies of software in any form. Pirated Software Software that has been illegally copied, or that is being used in violation of the software's licensing agreement. Pirated software is often distributed through pirate bulletin boards or on the Internet. In the internet underground it is known as Warez. Plain Text The opposite of Cipher Text, Plain Text is readable by anyone. PNS PPTP Network Server. A PNS must have IP connectivity. POP Post Office Protocol. This is a common protocol used for sending, receiving, and delivering mail messages. Port An Internet port refers to a number that is part of a URL, appearing after a colon (:) right after the domain name. Every service on an Internet server listens on a particular port number on that server. Most services have standard port numbers, e.g. Web servers normally listen on port 80.
P964 APR Cable Router with 802.11g Access Point Glossary K Port (H/W) An interface on a computer for connecting peripherals or devices to the computer. A printer port, for example, is an interface that is designed to have a printer connected to it. Ports can be defined by specific hardware (such as a keyboard port) or through software. POTS Plain Old Telephone Service is the analog telephone service that runs over copper twisted-pair wires and is based on the original Bell telephone system. Twisted-pair wires connect homes and businesses to a neighborhood central office. This is called the local loop. The central office is connected to other central offices and long-distance facilities. PPP Point to Point Protocol. PPP encapsulates and transmits IP (Internet Protocol) datagrams over serial point-to-point links. PPP works with other protocols such as IPX (Internetwork Packet Exchange). The protocol is defined in IETF (Internet Engineering Task Force) RFC 1661 through 1663. PPP provides router-to-router, host-to-router, and host-to-host connections. PPTP Point-to-Point Tunneling Protocol. Promiscuous Packet Capture Actively capturing packet information from a network. Most computers only collect packets specifically addressed to them. Promiscuous packet capture acquires all network traffic it can regardless of where the packets are addressed. Protocol A “language” for communicating on a network. Protocols are sets of standards or rules used to define, format, and transmit data across a network. There are many different protocols used on networks. For example, most web pages are transmitted using the HTTP protocol. Proxy Server A server that performs network operations in lieu of other systems on the network. Proxy Servers are most often used as part of a firewall to mask the identity of users inside a corporate network yet still provide access to the Internet. When a user connects to a proxy server, via a web browser or other networked application, he submits commands to the proxy server. The server then submits those same commands to the Internet, yet without revealing any information about the system that originally requested the information. Proxy servers are an ideal way to also have all users on a corporate network channel through one point for all external communications. Proxy servers can be configured to block certain kinds of connections and stop some hacks. PSTN Public Switched Telephone Network was put into place many years ago as a voice telephone call-switching system. The system transmits voice calls as analog signals across copper twisted cables from homes and businesses to neighborhood COs (central offices); this is often called the local loop. The PSTN is a circuit-switched system, meaning that an end-to-end private circuit is established between caller and callee. Public Key Encryption System of encrypting electronic files using a key pair. The key pair contains a public key used during encryption, and a corresponding private key used during decryption. PVC Permanent Virtual Circuit. A PVC is a logical point-to-point circuit between customer sites. PVCs are low-delay circuits because routing decisions do not need to be made along the way. Permanent means that the circuit is preprogrammed by the carrier as a path through the network. It does not need to be set up or torn down for each session. Ranging The process of automatically adjusting transmission levels and time offsets of individual modems in order to make sure the bursts coming from different modems line up in the right timeslots and are received at the same power level at the CMTS. Reconnaissance The finding and observation of potential targets for a cracker to attack. RFC An RFC (Request for Comments) is an Internet formal document or standard that is the result of committee drafting and subsequent review by interested parties. Some RFCs are informational in nature. Of those that are intended to become Internet standards, the final version of the RFC
P964 APR Cable Sharing Gateway with 4-port Switch L Glossary becomes the standard and no further comments or changes are permitted. Change can occur, however, through subsequent RFCs. RIP Routing Information Protocol is an interior or intra-domain routing protocol that uses the distance-vector routing algorithms. RIP is used on the Internet and is common in the NetWare environment as a method for exchanging routing information between routers. Router A device that connects two networks together. Routers monitor, direct, and filter information that passes between these networks. Because of their location, routers are a good place to install traffic or mail filters. Routers are also prone to attacks because they contain a great deal of information about a network. SAP In NetWare, the SAP (Service Advertising Protocol) broadcasts information about available services on the network that other network devices can listen to. A server sends out SAP messages every 60 seconds. A server also sends out SAP messages to inform other devices that it is closing down. Workstations use SAP to find services they need on the network. SATAN A UNIX program that gathers information on networks and stores it in databases. It is helpful in finding security flaws such as incorrect settings, software bugs and poor policy decisions. It shows network services that are running, the different types of hardware and software on the network, and other information. It was written to help users find security flaws in their network systems. Server A computer, or a software package, that provides a specific kind of service to client software running on other computers. Set-Top Box A set-top box is a device that enables a television set to become a user interface to the Internet and also enables a television set to receive and decode digital television (DTV) broadcasts. Shoulder Surfing Looking over someone's shoulder to see the numbers they dial on a phone, or the information they enter into a computer. SID (Service ID) Used in the DOCSIS standard to define a particular mapping between a cable modem (CM) and the CMTS. The SID is used for the purpose of upstream bandwidth allocation and class-of-service management. SNMP System Network Management Protocol is a popular management protocol defined by the Internet community for TCP/IP networks. It is a communication protocol for collecting information from devices on the network. Snooping Passively watching a network for information that could be used to a hacker's advantage, such as passwords. Usually done while Camping Out. SOCKS A protocol that handles TCP traffic through proxy servers. SPAM Unwanted e-mail, usually in the form of advertisements. Splitter Passive devices that divide the traffic on trunk cables and send it down feeder cables. Spoofing To forge something, such as an IP address. IP Spoofing is a common way for hackers to hide their location and identity SSL (Secured Socket Layer) Technology that allows you to send information that only the server can read. SSL allows servers and browsers to encrypt data as they communicate with each other. This makes it very difficult for third parties to understand the communications. STP Twisted-pair cable consists of copper-core wires surrounded by an insulator. Two wires are twisted together to form a pair, and the pair form a balanced circuit. The twisting prevents interference problems. STP (shielded twisted-pair) provides protection against external crosstalk.Straight throughA cable that wires a pin to its equivalent pin. This cable connects two dissimilar devices, for
P964 APR Cable Router with 802.11g Access Point Glossary M Ethernet cable example, a data terminal equipment (DTE) device and a data communications equipment (DCE) device. A straight through Ethernet cable is the most common cable used. SUA Single User Account – The Prestige's SUA (Single User Account) feature allows multiple user Internet access for the cost of a single ISP account - see also NAT. Subscriber Unit (SU) An alternate term for cable modem. TCP Transmission Control Protocol handles flow control and packet recovery and IP providing basic addressing and packet-forwarding services. Telnet Telnet is the login and terminal emulation protocol common on the Internet and in UNIX environments. It operates over TCP/IP networks. Its primary function is to allow users to log into remote host systems. Tempest Illegal interception of data from computers and video signals. Terminal A device that allows you to send commands to a computer somewhere else. At a minimum, this usually means a keyboard and a display screen and some simple circuitry. Terminal Software Software that pretends to be (emulates) a physical terminal and allows you to type commands to a computer somewhere else. TFTP Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP (File Transfer Protocol), but it is scaled back in functionality so that it requires fewer resources to run. TFTP uses the UDP (User Datagram Protocol) rather than TCP (Transmission Control Protocol). Three-way Cable Modem A three-way cable modem is a hybrid that can uses either a telephone modem or the TV cable for the upstream traffic. Trojan or Trojan Horse Like the fabled gift to the residents of Troy, a Trojan Horse is an application designed to look innocuous. Yet, when you run the program it installs a virus or memory resident application that can steal passwords, corrupt data, or provide hackers a back door into your computer. Trojan applications are particularly dangerous since they can often run exactly as expected without showing any visible signs of intrusion. Two-way Cable Modem A two-way Cable Modem uses the TV cable for both downstream and upstream traffic. UDP UDP is a connectionless transport service that dispenses with the reliability services provided by TCP. UDP gives applications a direct interface with IP and the ability to address a particular application process running on a host via a port number without setting up a connection session. UNIX A widely used operating system in large networks. Upstream The data flowing from the CM to the CMTS. Upstream Frequency The frequency used to transmit data from the CM to the CMTS. Normally in the 5 to 42 MHz range for US systems and 5 to 65 MHz range for European systems. URL (Uniform Resource Locator) URL is an object on the Internet or an intranet that resides on a host system. Objects include directories and an assortment of file types, including text files, graphics, video, and audio. A URL is the address of an object that is normally typed in the Address field of a Web browser. The URL is basically a pointer to the location of an object. VPN Virtual Private Network. These networks use public connections (such as the Internet) to transfer information. That information is usually encrypted for security purposes. Vulnerability Point where a system can be attacked. WAN Wide Area Networks link geographically dispersed offices in other cities or around the globe.
P964 APR Cable Sharing Gateway with 4-port Switch N Glossary Just about any long-distance communication medium can serve as a WAN link, including switched and permanent telephone circuits, terrestrial radio systems, and satellite systems. War Dialer A program that automatically dials phone numbers looking for computers on the other end. They catalog numbers so that hackers can call back and try to break in. Warez A term that describes Pirated Software on the Internet. Warez include cracked games or other programs that software pirates distribute on the Internet Web Configurator This is a web-based router (not all) configurator that includes an Internet Access Wizard, Advanced. Wire Tapping Connecting to a network and monitoring all traffic. Most wire tapping features can only monitor the traffic on their subnet. Worm A program that seeks access into other computers. Once a worm penetrates another computer it continues seeking access to other areas. Worms are often equipped with dictionary-based password crackers and other cracker tools that enable them to penetrate more systems. Worms often steal or vandalize computer data. WWW (World Wide Web) -- Frequently used when referring to "The Internet", WWW has two major meanings - First, loosely used: the whole constellation of resources that can be accessed using Gopher, FTP, HTTP, telnet, USENET, WAIS and some other tools. Second, the universe of hypertext servers (HTTP servers).
