SOME DEFINITIONS

Before you start . . .

there are a few terms that you need to understand so that you know

what the system is doing and what the displays mean.

Access Code

This is a number dialed from the console dial pad or from an extension

to activate a particular system feature. For example, you dial an access

code to call a Hunt group.

Extension, or Internal Line

Each telephone in the system is called an extension and is given an

extension number. These appear on the display as “EXT-123” and so

on. Extensions can be either standard rotary dial or push-button

phones, or special SUPERSET@ feature phones.

Trunk

Trunk is the general name for both Outside Lines and Tie Trunks. It is

any line that connects your system to a local exchange or another

private system.

Outside, or External Line

This is a line that connects your system to the local telephone

exchange, and therefore to the public telephone network.

Tie Trunk

This type of line directly connects your system to another telephone

system owned by your company or organization. You do not have to

use the public telephone network to dial this location, and the general

public usually do not have access to the line.

incoming Trunk Calls

Depending on what type of call it is, an incoming call is put into one of

three possible listed directory numbers (LDN’s) which appear at the

console display as LDN 1, 2, or 3. One of your LDN’s could consist of

numbers used by the general public, another for trunks connecting

your telephone system to several other PABX’s owned by your

company. You may have instructions on the specific manner in which

to answer calls depending on the LDN on which they appear.

Trunk Eg.Gpment Number

Every trunk is given a unique number within your system so that it can

be identified from other trunks that may all share the same outside

telephone number. The trunk number appears in the display as, for

example, “TRK-10”.
