 Selectors 1 through 3: Dial tone/busy tone detection level during recording of ICM
If the machine (called station) detects dial tone (400 Hz continuously) or busy tone (400 Hz
intermittently) exceeding the detection level specified by these selectors for the period specified by
selectors 1 through 4 of WSW35, then it interprets the calling station as being disconnected. The
machine stops TAD recording and disconnects the line.
