NOTE: Selectors 1 through 5 are applicable to those models equipped with a built-in TAD.
Selectors 1 through 3: Erasing time length of ICM tone recorded preceding the tone detection
l
If the equipment has disconnected the line after detection of disconnection tone in ICM recording,
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
l
The equipment interprets a CNG as an effective signal if it detects a CNG signal by the number 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
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.
