Protocol NO LMI, Q.933-A or T1.617-D. The default setting is TL617-D.
If NO LMI is selected, the following fields are displayed:
DLCI Address
: This field can be set to values from 0–1023. The values 0–15 and 1008–1022 are reserved DLCI
(Data Link Connection Identifiers) addresses.
The values 16–991 are typically used for virtual circuits.
Circuit State
: Toggles between Active, Inactive and Invalid.
2-6 WPIM-DDS Local Management Guide
WPIM-DDS Configuration
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 active 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 assigned to that Interface. This is determined either manually or by the Link Management Protocol.
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.
STATE
Displays the status of the application port. If the active protocol is Frame
Relay, this field displays the status as Active, Inactive, or Invalid
(no LMI). If the active protocol is PPP, this field displays UP (active) or
DOWN (inactive).

If you selected PPP, use the arrow keys to highlight PPP Type.
Press the SPACE bar to select BNCP or LEX, then press ENTER.
Go to Step 4.
b. If you selected FR, use the arrow keys to highlight FR LMP. Press the SPACE bar to select T1.617-D, Q.933-A, or NO LMI, then press ENTER.
If you selected NO LMI, complete the following:
• Use the arrow keys to highlight DLCI Address. This field can be set to values from 0-1023. The values 16-991 are typically used for virtual circuits.

Data Communications Equipment. A device such as a modem that connects the communications circuit with the end device
(see DTE).
Data (D)
Channel
DDS
A 16 Kbps channel used with BRI and PRI services for signaling and control.
Digital Data System. A private line digital data service with a typical data rate of 56 Kbps.
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 identifier 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. A device which converts RS232 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.

Wan Terms And Acronyms
HDLC
INV-HDLC
High-Level Data Link Control. A layer 2 (link layer) full-duplex protocol derived from SDLC.
A form of zero suppression in which all zeros in the HDLC packet are changed to ones and all ones are changed to zeros.
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. A 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 signals 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.

Time Division Multiplexing. A technique in which separate data or voice signals are transmitted simultaneously over a single communications medium based on time interleaving.
A standard 64,000 bit/second channel. Synonymous with DS-0
(Digital Signal, level 0).
Wide Area Network. A network spanning a large geographic area.
WAN Physical Interface Module, Cabletron Systems modules that provide connectivity/functionality for WAN modules such as the BRIM-W6.
