Line Access Keys

The flexible line keys on a Proprietary Telephone may be set to any of the following three
functions:.

Trunk Group (G-CO) Key

Receiving or making outside calls is on an trunk group basis. The trunk group is assigned in
program [404]. Any incoming call from any exchange line in the trunk group arrives at the G-
CO key. To make an outside call,the user can access an idle exchange line in the group by
simply pressing the assigned G-CO key.

Single Exchange Line (S-CO) Key

Receiving or making outside calls is done using a specific exchange line. An incoming call
from the specific exchange line arrives at the S-CO key. To make an outside call,the user can
access the specific exchange line by simply pressing the assigned S-CO key.

Other Exchange Line (O-CO) Key

Exchange lines,which are not assigned to an S-CO or G-CO key,can be assigned to a flexible
line key as the O-CO key. An incoming call on an exchange lines arrives at the O-CO. To
make an outside call,the user simply presses the assigned O-CO key.

Log-In/Log-Out

Allows an extension user to Log-In (join) or Log-Out (leave) a hunting, DISA ring or UCD
group temporarily. Extensions in the log-out mode will not receive calls by Extension
Hunting, DISA or UCD but will receive other calls, not like the Do Not Disturb (DND)
feature. The Log-In/Log-Out button can be assigned to a flexible button in the Proprietary
Telephone Settings. The lighting patterns of the Log-In/Log-Out button on a proprietary
telephone and status are as follows.
Off: Log-In mode
Red: Log-Out mode

Message Waiting

Allows an extension user to notify an extension of a message waiting when the extension is
busy or does not answer the call. Only a proprietary telephone user with a MESSAGE button
can receive a message. If the LED on the MESSAGE button lights red there is a message
waiting. Pressing the lit MESSAGE button will reply to the message by calling the extension
which left the message. The messages which are stored in the mailbox of the Voice
Processing System can also be heard by following the Voice Mail prompts after pressing the
lit MESSAGE button.

Music on Hold / Background Music (BGM)

An external music source may be connected to the system to provide music to callers
on hold and background music through the speakers of proprietary telephones.
