Chapter 2 - Digital Station Features
CO Line - Loop Button
A station not having a direct appearance for a CO line receives incoming CO calls and
transferred CO calls under the LOOP button. Only one call at a time can be connected to a
keyset on the LOOP button.
If more than one LOOP button is on a key set, the LOOP buttons may be conferenced
together.
If all programmed LOOP buttons on a keyset are busy or have a CO call on hold, the party
attempting to transfer a CO line to that station receives busy tone and cannot transfer the
call to that station.
If a transfer is attempted, the CO line recalls the initiator immediately.
CO lines are also presented to a Loop when dialing out using LCR or when using speed dial to
dial out and the line chosen does not appear on the key station.

CO Line - Pool Button Operation
The Pool Group feature is used primarily to access CO lines that do not appear on a station, so
that outgoing calls may be made. Pooled group keys are associated to CO line groups and
may be programmed for use on any of the flexible buttons. CO lines are accessed in
descending order of priority starting with the highest numbered available (not busy) CO line
in a CO line group. Stations may have as many POOL buttons as there are CO line groups.
Multiple POOL buttons for the same group are also allowed.
CO Line - Queuing
When all the outside lines in a group are busy, stations can be placed in queue awaiting a line
in the same group to become available. If a station doesn't answer the queue signal within
15 seconds, that station is dropped from the queue.
