Configuring line access
Assigning intercom (I/C) buttons (keys)
The Intercom keys attribute assigns the number of intercom buttons that display on a telephone.
Intercom buttons provide access to a maximum of eight internal and/or external lines and line
pools. The user presses the intercom key to answer internal calls, or to select a line or line pool to
make a call. Lines configured for ring-only also appear on intercom buttons.
• If you assign a prime line to an intercom key, when you press the button or pick up the handset
you are immediately connected to a line and a line indicator appears beside the intercom button.
• When you assign each intercom button during programming, it automatically appears on the
telephone. The intercom buttons appear starting at the lower-right button, or one button above it
if the handsfree feature appears on the telephone. They overwrite any feature or line
programming that existed on that button. They do not overwrite answer DNs. Instead, the
answer DNs are pushed up one button.
• A telephone requires two intercom button to establish a conference call with two other Business
Communications Manager telephones.
• You require only one intercom button if the button is used to make and receive internal calls,
and to access line pools. Doorphones only require one intercom key.
• You require two intercom buttons for a telephone with several lines assigned to Ring only.
• The 7000 and 7100 digital phones and analog telephones are automatically assigned two
intercom buttons. This allows users to toggle between two active calls using the Hold button.
