CO Line Pool 4-37
CO Line Pool
Description
The CO Line Pool assignment preserves feature buttons and reduces the number of
individual CO line appearances required at a key telephone. The CO Line Pool allows
random CO line outgoing access and becomes a virtual Answer button, with illumination,
for receiving incoming or transferred calls. A CO Line Pool button can be assigned to
access CO Line Group 1, CO Line Group 2, CO Line Group 3, CO Line Group 4, or All CO
Line Groups. Alternatively, CO Line Groups (1-4) can be assigned to separate distinct
feature buttons. Dialing code [9] is not allowed.
Operation
1. Press the feature button programmed for CO line group operation. An idle CO line in
the associated group will be accessed. (The last CO line in the group is always
accessed first. When the feature button is programmed for
All Group operation, the
last CO line in the highest group number is accessed first.) The group button LED is
green and blinking.
2. If CO Lines are camped-on by other key telephones or busy, busy tone will be heard
and the display will show the following.
Conditions
†
When all CO lines in a certain group are busy, any attempt to access an idle CO line by
pressing the CO line group button will receive busy tone, and the system will assign
any busy CO line for the station to establish Camp On Busy CO Line.
†
If a station has multiple CO line group buttons programmed without any individual
CO Line buttons, Incoming calls will be indicated on only one idle CO Line Group
button, to which the CO Line is assigned.
†
If a station has a group button and individual CO Line button, an incoming CO Line
call will be indicated only on an individual CO Line button.
†
When pressing an individual CO Line button, the LED indication on an assigned
group button will not be affected.

Any programmable feature button may be programmed as a CO line group
button. Even if a key telephone has no CO Line or CO line group buttons
assigned, an outside CO line call can be transferred to the station. There will
be no visible LED indication at the called station.
