the unit starts to detect CNG signal.
When CNG signal is received,
the unit switches to FAX receiving.
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,

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.
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.
