Notes about assigning lines to telephones
Read these notes for more information about assigning lines to telephones.
• The Business Communications Manager Analog Terminal Adapter (ATA2), or a portable
telephone cannot process more than two simultaneous calls.
• Nortel Networks recommends a maximum of four line buttons per telephone. You can program
more than four line buttons on a telephone by programming less than four on other sets. For
example, you might program 20 line buttons on a receptionist telephone equipped as a CAP
station and only two lines on all other telephones.
• You can program a maximum of 93 telephones with a line appearance for a specific line,
including VoIP and target line s . Above this maximum, you can configure more than one
appearance per telephone of a target line.
• Do not assign auto-answer loop start trunks, auto-answer T1 E&M trunks and T1 DID trunks to
telephones. If assigned, use them to monitor incoming call usage, or make outgoing calls
(auto-answer loop start and T1 E&M trunks).
• You cannot assign a line that is configured to private to another telephone.
• Each line assigned to appear at a telephone must appear at a button with an indicator. The
maximum number of line buttons is eight for the 7208 digital phones, 10 for the 7310 and 7316
digital phones, 16 for the 7316E digital phones, and 24 for the legacy 7324 telephone.
However, you need to also consider other button requirements such as intercom button
s and
Vmsg set N or Y Select whether an indicator shows on the telephone for voice
message waiting to an external voice message system.
The line must appear on receiving telephone.
Note: the Message Waiting Indicator (MWI) is currently supported
exclusively by Meridian Mail and CallPilot.
MCDN note: If your system is part of an MCDN network connected
to a Meridian 1 system, and you are using the voice mail system off
the Meridian 1, you need to set this field to Y.
Analog lines connected to legacy analog ASM station modules,
and analog telephones attached to an ATA device, do not provide
visible message waiting indication. Analog telephones connected to
a GASM (Global Analog Station Module) support message
indicators, if the telephone is set up to receive them.
Note: Contact your voice message service provider to find out if your voice message
service works with Business Communications Manager, or if you have any problems
with your service.
Caution: PRI Lines
Users cannot access PRI lines directly through line appearances.
PRI lines must be part of a line pool.
If you change a digital trunk module (DTM) to PRI, the system automatically removes all
existing line appearances for that module.
