# EXTERNAL TAM OPERATION UNIT OPERATION
1 When the bell signal rings as many times as the number
memorized into the connected answering machine (TAM),
the answering machine is connected to the line and the
answering message is sent out to the line. (OGM out for 8
~ 16 sec.) The length of the answering message should be 8~16
seconds.
While the message is being played, the unit starts to
detect the CNG signal.(A)
If the unit detects the CNG signal, it will switch to FAX
receiving and disconnect the external TAM automatically.
2 After sending the OGM, the answering machine starts to
record the message of the other party (ICM recording). After the OGM of the external TAM is finished, the unit
starts to detect approximately 5 seconds of no sound
detection. (B)
If no sound is detected, the unit will switch to FAX
receiving and disconnect the external TAM automatically.
If the unit cannot detect the CNG signal or no sound for
about 30 seconds, the unit will disconnect the line. (C)
Attention 1:
No sound detection lasts 20 seconds after the telephone call is received at the answering machine. If there is no sound for more
than 5 seconds (#701 in the service mode), it switches to the facsimile.
Attention 2:
When the answering machine cannot answer the telephone call because of disconnection or the recording tape is full, the unit
picks up the call after 5 rings (#702 in the service mode). Then it switches to the facsimile.
