COMSPHERE 3800Plus Modems

LCD

Liquid Crystal Display. A thin sandwich of two sealed glass plates containing liquid

 

crystal material. When voltage is applied, the amount of light able to pass through the

 

glass plates is altered so that messages may be ``writtenº on the display.

leased line

A private line connection exclusively for the user. No dialing is necessary.

LED

Light-Emitting Diode. A light or status indicator on the DCP that glows in response to

 

the presence of a certain condition (e.g., Alrm).

local analog loopback

The modem's transmit VF signal is looped to its receiver.

long space disconnect

A disconnect can occur if the modem receives an extended space from a remote modem;

 

for example, when a remote modem is commanded to disconnect, it transmits a

 

continuous space to the modem before disconnecting.

loopback test

Any test that verifies a device's integrity by connecting the device's output of one

 

direction to the device's input of the other direction, then checking the received signal for

 

errors.

LSD

Line Signal Detect. A signal between the DTE and modem indicating energy exists on

 

the transmission circuit.

menu tree

The structure containing the 3800Plus menu hierarchy starting at a Top-Level menu and

 

extending down to various modem functions.

MNP

This protocol (Microcom Networking Protocol) detects and corrects data errors caused

 

by telephone line noise and signal distortion. MNP5 includes data compression.

modem

(Modulator/DEModulator). A device that transforms signals from digital to analog form

 

and vice versa.

modulation

The process of varying some characteristics (usually amplitude, frequency, and/or phase)

 

of a carrier wave to form data transmissions.

network

A communications circuit.

network address

The customer-assigned diagnostic address of a tributary modem.

NIM

Network Interface Module. The interface provided, up to two per carrier, for the public

 

switched telephone network (PSTN) used by 3811Plus modems.

NMS

Network Management System. A set of diagnostic and configuration management tools

 

for a data communication network, consisting of software programs and dedicated

 

computer hardware.

off-hook

The condition of a telephone or modem that is being used to establish or maintain

 

communication.

offline

The condition of a modem that is not connected to another modem.

on-hook

The condition of a telephone or modem that is not being used.

online

The condition of a modem that is connected to and communicating with another modem.
