Note:
Selectors 1 through 5 are applicable to models equipped with
-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 machine 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 (when the line is connected via the external telephone in the external TAD mode or via the machine in F/T mode)
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 external telephone in the external TAD mode or via the machine in F/T mode.
-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.
