WSW34 (Function setting 12) Selector No. 1 | 3 4 5 Function Not used. No. of CNG cycles to be detected (when the line is connected via the machine or external telephone except in the external TAD mode) 6 Number of DTMF tone signals for inhibiting the detection of CNG 7 during external TAD operation CNG detection when the external 8 telephone is connected with a line in TAD mode Setting and Specifications No. 6 7 0 0 : 0.5 (A) 01 : 1 (B) 1 0 : 1.5 (C) 11 : 2 (D) No. 6 7 00: 01: 10: 11: 3 2 1 OFF 0: Only when the 1: Always equipment detects itself being called NOTE: Selectors 4 and 5 are not applicable to the American version. l Selectors 4 and 5: No. of CNG cycles to be detected The machine 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 machine or external telephone except in the external TAD mode. l Selectors 6 and 7: Number of DTMF tone signals for inhibiting the detection of CNG during external TAD operation If the machine 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. l 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.
