HDB3

WPIM-DI Local Management Guide

D-3

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.

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. Also may be referred to as clock slave 
timing.

MIM

Media Interface Module, Cabletron Systems products 
designed to fit in a Multi Media Access Center (MMAC) 
hub.
