Account Code
A code you dial to access certain system features; to apply your
Class of Service (COS) at a different extension; or to associate a
caller with an SMDR record for accounting purposes.
ARS - Automatic Route Selection
This is an application that handles long distance call routing
automatically.
Broadcast Group
When a line has an appearance on another telephone, it is said to
be in a broadcast group. This means that all extensions with that
line appearance have access to and may use that line.
Call Privacy (Data Line Security)
A COS feature which prevents an extension from receiving Camp-
on Tone -- which could interfere with data transmission.
Camp-on
A feature allowing the system to queue calls directed to a busy
extension, then automatically connects the waiting party to the
extension when it becomes free. The busy extension user hears
Camp-on Tone indicating a call is camped-on. The waiting caller
is put on hold and hears music or silence.
Class of Restriction (COR)
Control of a station or trunk’s access to trunk circuits. A station
may have up to three different CORs specified for Day, Night 1 or
Night 2 Service.
Class of Service (COS)
A level of service defined by a specific set of features that controls
an extension’s access to these features. A station may have up to
three different COSs specified for Day, Night 1 or Night 2 Service.
Consultation Hold
A temporary hold applied to a call while an extension or console
user activates a feature or makes a call.
Customer Data Entry (CDE)
The entry of programmed data, specific to the customer’s
requirements. Customer data includes such items as directory
information, COS and COR allocations, and trunk data.
Direct Inward Dialing (DID)
This feature allows outside trunks to reach pre-programmed
extensions directly, without going through the Attendant console.
Direct Inward System Access (DISA)
A feature which allows callers to dial directly into the telephone
system and activate features and facilities.
External Line Access Code
A code which precedes a dialed number to indicate to the
telephone system that the telephone number is outside the
system.
Firmkeys
Keys on the console keypad that can be programmed to access
console features and system services.
Hunt Group
Extensions linked together in a group with a common (pilot)
telephone number as well as their own personal extension
numbers. Two types of hunting are available with your telephone
system: Circular Hunting and Terminal Hunting.
Circular Hunting: A new call to the Hunt Group is directed to the
first idle extension found after the extension, which received the
last call. This provides equitable call distribution to all the
extensions.
Terminal Hunting: Hunting takes place in the order in which the
extensions were programmed into the hunt group. It always
starts with the first extension in the list and the hunting ends
with the first idle extension found.
