Appearances - Nortel ICS Install Manual

Appearances

This setting only applies for direct inward dial (DID) digits
mapped onto target lines.
The Norstar system can handle simultaneous calls to a
telephone with multiple target line appearances (157 to 284 for
MICS, 157 to 380 for XC). The number of target line
appearances depends on the line assignment setting, which
include: Appr&Ring, Ring only, and Appr only.
If Appr&Ring or Appr only is chosen, you can have as many
simultaneous DID calls as there are target line key
appearances. If Ring only is chosen, you can have as many
simultaneous DID calls as you have intercom keys.
When a trunk card is changed to PRI, all existing line
appearances for that card are automatically removed.
Telephones without line buttons, telephones connected
through an ATA2, portable telephones, and BRI ISDN
S-terminals cannot process more than two simultaneous calls.
There is a suggested limit of four line keys per telephone. You
can program more than four keys on a telephone by
programming less than four on other telephones. For instance,
you might program 20 keys on a receptionist telephone
equipped with a CAP and only three keys on the 20 telephones
connected to the CAP.

Users cannot access PRI lines directly
through line appearances or line pools. All
outgoing PRI calls are dialed through the
intercom button, using destination codes.
