The equipment interprets a CNG as an effective signal if it detects a CNG signal by the number of
cycles specified by these selectors when the line is connected via the facsimile equipment or
external telephone except in the external TAD mode.
Selectors 6 and 7: Number of DTMF tone signals for inhibiting the detection of CNG during external
l
If the equipment receives this specified number of DTMF tone signals during external TAD
operation, it will not detect CNG afterwards.
If these selectors are set to "1, 1," the CNG detection will not be inhibited.
Selector 8: CNG detection when the external telephone is connected with a line in TAD
l
If this selector is set to "0," the equipment will detect a CNG signal only when it detects itself being
called. If the external telephone is connected with a line before the equipment detects itself being
called, the equipment will not longer detect a CNG signal.
If this selector is set to "1," the equipment will detect a CNG signal every time the external
telephone is connected with a line, even without detecting itself being called.
