Fax Message Waiting Receiver and Threshold
4-4 Telephone Features
If the telephone has a personal line assigned, you can specify that incoming
calls on that trunk also can be forwarded to an outside number by assigning the
telephone as the principal user of the personal line.
Notes:
When a principal user is assigned, calls received on the personal line are
also sent to individual or group coverage receivers unless the personal line
button is set for no ring.
Remote Call Forward cannot be assigned to queued call consoles.
Planning Form Instructions
Under the "Remote Call Forward" heading on Forms 4a through 5c:
1. Check "Not allowed" to keep the factory setting.
2. Check "Allowed" to provide Remote Call Forward.
Under the "Principal User of Personal Line" heading:
3. Write the trunk number and telephone number in the spaces provided if
you want the person to forward calls on the personal line to a remote
number. (Refer to PBX Xyxtem Form 2c, System Numbering - Trunk

Use these instructions only if the system has fax machines connected
directly to the control unit via a 008 OPT or 012 module or connected to an
MLX telephone using a Multi-Function Module (MFM). These instructions are
not applicable to fax machines connected to an analog multiline telephone using
a General Purpose Adaptor (GPA).
Fax Message Waiting Receiver allows you to designate
telephones to receive message-waiting indications when a fax is received on a
specific fax machine. Fax machines can only send message-waiting indications;
they cannot receive message-waiting indications from other fax machines.
You can specify the Fax Message Threshold, which is the length of time
(0-30 seconds) before the system assumes a fax has arrived and sends the
message-waiting indication. The" factory setting is 10 seconds.
