A typical packet holds 512 bytes of information, so it takes many packets to transfer a large file over a network. As packets traverse a network, the addressing information contained in them is used by bridges and routers to direct packets to their destination, or keep them off of networks where they don't belong.
  • Page 97 Appendix C - Network Overview IP Addressing Every node on an IP network requires a 4-byte numeric address that identifies both a network and a local host or node on the network. This address is written as four numbers separated by dots, for example, 148.1.9.1.

    MultiFRAD User Guide Appendix D - Disabling the Internal DSU Perform the following procedure if your WAN network has been upgraded to T1/E1 and you now want to disable the MultiFRAD’s internal DSU and use the back panel Trunk connection to obtain data rates of up to 2.048 Mbps.

  • Page 100 MultiFRAD User Guide Access: The T1 line element made up of two pairs of wire that the telephone company brings to the customer premises. The Access portion ends with a connection at the local telco (LEC or RBOC). Accunet Spectrum of Digital Services (ASDS): The AT&T 56K bps leased (private) line service. Similar to services of MCI and Sprint.
  • Page 101 Glossary Basic Rate Interface (BRI): An ISDN access interface type comprised of two B-channels each at 64K bps and one D-channel at 64K bps (2B+D). Bell Operating Companies (BOC): The family of corporations created during the divestiture of AT&T. BOCs are independent compa- nies which service a specific region of the US.
  • Page 102 MultiFRAD User Guide Channel bank: A device that acts as a converter, taking the digital signal from the T1 line into a phone system and converting it to the analog signals used by the phone system. A channel bank acts as a multiplexer, placing many slow-speed voice or data transactions on a single high-speed link.
  • Page 103 Glossary Device driver: Software that controls how a computer communicates with a device, such as a printer or mouse. Digital Cross-connect System (DCS): The CO device which splits and redistributes the T1 bandwidth. The DCS takes time slots from various T1 lines and alters them to provide the needed connectivity. DCS connections are made with software at an administrator's workstation.
  • Page 104 MultiFRAD User Guide Exchange Termination (ET): The carrier's local exchange switch. Contrast with "Loop Termination - LT". Explicit Congestion Management: The method used in frame relay to notify the terminal equipment that the network is overly busy. The use of FECN and BECN is called explicit congestion management. Some end-to-end protocols use FECN or BECN, but usually not both options together.
  • Page 105 Graphical User Interface (GUI): A type of computer interface consisting of a visual metaphor of a real-world scene, often of a desktop. Within that scene are icons, representing actual objects, that the user can access and manipulate with a pointing device. Handshaking: A process that two modems go through at the time of call setup to establish synchronization over the data communica- tions link.
  • Page 106 MultiFRAD User Guide LAPB: Link Access Procedure Balanced; based on the X.25 Layer 2 specification. A full-duplex point-to-point bit-synchronous protocol commonly used as a data link control protocol to interface X.25 DTEs. LAPB is the link initialization procedure that establishes and maintains communications between the DTE and the DCE.
  • Page 107 Glossary Multiprotocol: A device that can interoperate with devices utilizing different network protocols. Multithreading: The ability of a software system to be able to handle more than one transaction concurrently. This is contrasted to the case where a single transaction is accepted and completely processed before the next transaction processing is started. Nailed Connection: A permanent or dedicated circuit of a previously switched circuit or circuits.
  • Page 108 MultiFRAD User Guide Point of Presence (POP): The central office's end points of the long distance carriers. Point to Point Protocol (PPP): A protocol that lets a PC user access TCP/IP (Internet member) using an ISDN terminal adapter or a high-speed modem over a standard telephone line.
  • Page 109 Glossary Robbed Bit Signaling: The popular T1 signaling mechanism where the A and B bits are sent by each side of the T1 termination and are "buried" in the voice data of each voice channel in the T1 circuit. Since the bits are "robbed" infrequently, voice quality is remains relatively uncompromised.
  • Page 110 MultiFRAD User Guide Synchronous Transmission: The transmission of data which involves sending a group of characters in a packet. This is a common method of transmission between computers on a network or between modems. One or more synchronous characters are transmitted to confirm clocking before each packet of data is transmitted.
  • Page 111 Glossary Transport Layer: Layer 4 of the Open Systems Interconnection (OSI) model; provides reliable, end-to-end delivery of data, and detects transmission sequential errors. Transport Protocol Data Unit (TPDU): A transport header, which is added to every message, contains destination and source addressing information that enables the end-to-end routing of messages in multi-layer NAC networks of high complexity.
