●
Selectors 1 through 3: Erasing time length of ICM tone recorded preceding the tone detection
starting point in the case of automatic line disconnection due to no
voice signal received
If the equipment has disconnected the line after detection of disconnection tone in ICM re-
cording, it erases tone recorded preceding the tone detection starting point for the time
length set by these selectors.
●
Selectors 4 and 5: No. of CNG cycles to be detected (For those models equipped with a built-
in TAD)
The equipment interprets a CNG as an effective signal if it detects a CNG signal by the num-
ber of cycles specified by these selectors in any of the following cases:
• when the line is connected via the external telephone in the external TAD mode.
• when the line is connected via the facsimile equipment in F/T or 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, 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.
