Operating Procedure
To answer a Manual INTERCOM call:
1.
The MICM key will flash, indicating an incoming INTERCOM call. The called station may also
hear one second of ringing from the calling INTERCOM station.
2.
If the called station in the INTERCOM group is already engaged in a conversation with a non-
INTERCOM call, the station may press the MICM key after pressing the HLD key.
To bridge into a Manual INTERCOM call:
1.
When two stations are engaged in an INTERCOM call, a third station, belonging to the same
INTERCOM group, will press the MICM key and go off-hook.
2.
A three-party conference is established. The called stations may hear a Warning Tone when the
station bridges into the call. This Warning Tone is preassigned in System Data.
Use of the SIG key:
1.
The Manual INTERCOM Signal (SIG) key is operational at all times. An INTERCOM call is not
required. If the signaled station is ringing from another call, the Manual INTERCOM signal will
interrupt that ringing.
PRIME LINE PICK UP - D
•
term
The D
may be programmed to seize the incoming call on the AUTOMATIC, MANUAL, or DIAL
INTERCOM [D-87] lines before the Prime Line. If two incoming calls terminate simultaneously to the
Prime Line and the MICM line, when the station user goes off-hook, PRIME LINE PICK UP-D
will seize the MICM line before the Prime Line. If only the Prime Line is ringing when the station user goes
off-hook, PRIME LINE PICK UP-D
