THE WAN INTERFACE CONFIGURATION SCREEN

PT#

Displays the application ports (bridge ports) available from the host platform to the WAN. If the active protocol is PPP, Local Management assigns only one application port per interface number (IF#). If the activ e protocol is Frame Relay, Local Management assigns the available WAN bridge ports from the host platform, one per DLCI.

The quantity of application ports for a Frame Relay network is determined by the quantity of DLCIs (Data Link Connection Identiﬁers) assigned to that Interface. This is determined either manually or by the Local Management Interface.

IF#

Displays the Interface that is associated with the application port.

LID

Displays the Link Identiﬁer. If the active protocol is Frame Relay, the Data Link Connection Identiﬁer is displayed. If the active protocol for this interface is PPP, then PPP appears in this ﬁeld.

APPENDIX B: WAN TERMS AND ACRONYMS

DCE Data Communications Equipment, a device such as a modem

that connects the communications circuit with the end device (see DTE).

Data (D) Channel

A 16 Kbps channel used with BRI and PRI services for signaling and control.

D4 D4 Framing, a popular framing format in T-1. Uses 12 T-1

Frames to identify both the channel and the signaling bit.

DLCI Data Link Connection Identiﬁer, a unique virtual circuit identi-

ﬁer used in Frame Relay. Identiﬁes a given frame as being from a particular logical link. The DLCI has only local signiﬁcance.

DSU Digital Service Unit, converts RS-232 or other terminal

interfaces to DSX-1 (T-1) interface.

DS-0 Digital Signal, level 0, a standard 64,000 bit/second channel.

Synonymous with “Timeslot.”

DTE Data Terminal Equipment, equipment that originates and

terminates data transmission such as a computer or printer (see DCE).

E-1 European digital signal level 1. Similar to T-1 but provides 32

channels (2.048 Mbps) instead of 24 channels (1.544 Mbps).

ESF Extended Super Frame. A new T-1 framing standard (see D4

framing) that uses 24 T-1 frames, thus allowing individual identiﬁcation of the channel and signaling bits.

Fractional T -1 Use of a portion (less than the full 24 channels) of a T-1 line. Frame Relay A network protocol that allows for many point-to-point virtual

connections over a single access channel.

HDB3 High Density Bipolar 3, used with E-1, a bipolar coding

method that does not allow more than 3 consecutive zeros.

HDLC High-Level Data Link Control, layer 2 (link layer) full-duplex

protocol derived from SDLC.

INV. HDLC A form of zero suppression in which all zeros in the HDLC

packet are changed to ones and all ones are changed to zeros.

APPENDIX B: WAN TERMS AND ACRONYMS

ISDN Integrated Services Digital Network. Allows point-to-point

connections at 64 Kbps or 128 Kbps when necessary and disconnects the line when not in use. With this service the user only pays for the time connected.

JBZS Jam Bit-Zero Suppression, a form of zero suppression that

places a one in the seventh bit of a timeslot. Reduces the effective throughput to 56 Kbps.

LEX LAN Extender, a Cisco Systems protocol used to internetwork

a host-based router with a remote switch.

LMP Link Management Protocol, used in Frame Relay. Allows the

device to gather information about the DLCIs (Data Link Connection Identiﬁers) See T1.617-D, Q.933-A.

Local Timing Timing for digital transmission circuit is internally generated

by a source within the equipment. Usually used for short haul private lines. In this case one CSU must be set for Local (internal) timing and the CSU at the other end of the line must be set for Loop (recovered) timing to create a master-slave situation.

Loop Timing Timing for digital transmission circuit is recovered from the

received data, not generated internally by a source within the equipment. This is the typical situation when using public lines.

MIM Media Interface Module, Cabletron Systems products designed

to ﬁt in a Multi Media Access Center (MMAC) hub.

MUX Multiplexer, an electronic device that allows two or more sig-

nals to pass over one communications circuit.

PPP Point-to-Point Protocol, provides a method for transmitting

datagrams over serial point-to-point links.

PRI Primary Rate Interface, an ISDN service providing 23 “B”

(Bearer) channels of 64 Kbps and one 64 Kbps “D” (Data) channel for signaling and control.

PVC Permanent Virtual Circuit, a virtual circuit that provides the

equivalent of a dedicated private line service.

tion used in Frame Relay.
