9.1.9. Check TAM Operation
A) How to change the Auto Disconnect activation (time)
Some Telephone Company lines (fiber or cable) ON Hook and OFF Hook voltages are lower than conventional lines, which may
cause a malfunction of Auto Disconnect detection. To solve this problem, try changing the Auto Disconnect activation through
the procedures below.
Note:
*1 Auto Disconnect doesn't detect for the first 2 seconds.
*2 If the “Disable” is selected, even if the parallel-connected telephone is OFF HOOK, the line isn’t disconnected.
B) How to change the VOX level
It makes easier to detect a small voice (caller) by raising the sensitivity of VOX level. Therefore, the recording of TAM is not
turned off during a detection.
