Selectors 4 and 5: No. of CNG cycles to be detected 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 in the F/T mode or via the external telephone in the external TAD mode. Selectors 6 and 7: Number of DTMF tone signals for inhibiting the detection of CNG during external TAD operation If the equipment receives this specified number of DTMF tone signals during external TAD operation, then 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 mode 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 no 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.
