When bell signal rings as many as the numbers
which installed in the connected answering machine,
the answering machine seizes the line,
then answering massage is out to the line.
The length of response messages
should be 8~16 seconds.
While response massage is being played,
the unit starts to detect CNG signal.
When CNG signal is received,
the unit switches to FAX receiving.
OPERATION EXPLANATION
When there is approximately 5 seconds’ no sound
situation for 20 seconds after being passed
10 seconds, the unit switches to FAX receiving.
During this period it detects CNG signal also.
When it cannot detect no-sound nor CNG,
it doesn’t switch to FAX receiving,
the unit doesn’t catch the line.
(The answering system hangs up the line.)
10 seconds after the answering machine gets
the telephone call, no-sound detection begins.
Attention 1: No sound detection lasts 20 seconds after the telephone call comming in to the answering machine. If there
is no sound situation for more than 5 seconds (#701 in the service mode) it is switched to the facsimile.
Attention 2: When answering machine can’t catch the telephone call because of the disconnection or no capacity in the
tape, the unit catches the call after 5 times’ bell ring (#702 in the service mode), then switches to facsimile.
When you install in Service, it is possible for the unit not to catch phone calls.
