Intercom Keys - Nortel ICS Install Manual

Remember that if you set prime line to I/C (intercom), you may
wish to assign loop start lines to the first line pools. When the
system searches for an outgoing line, it begins at line pool A
and chooses the first available line.
By assigning a line pool as a prime line, a telephone can be
made to search automatically for an idle line in a pool. This is
described in the section on programming Line type (Trk/Line
Data).

Intercom keys

This setting assigns the number of intercom buttons to a
telephone. Intercom buttons provide a telephone with access to
internal lines and line pools.
Press CHANGE to select the setting: 0, 1, 2, 3, 4, 5, 6, 7, or 8.
Tips -
programming automatically appears on the telephone. The
buttons start with the lower right-hand button, or one button
above, if the handsfree/mute feature is assigned to the
telephone.
A telephone needs two intercom buttons to be able to establish
a conference call with two other Norstar telephones.
Only one intercom button may be required if the button will
only be used to make and receive internal calls, and to access
line pools.
Two intercom buttons are required if a telephone has several
lines assigned to ring only.
The model 7000 and 7100 digital phones and the Digital
Mobility phones default to two intercom positions. This allows
the user to have two active calls at once, with one of them on
Hold.These intercom assignments do not appear on buttons on
the telephone.
