Note
These parameters control the busy tone
detection. They are used for call termination
and automatic dialling.
All continuous, busy and ringing tones are
detected. Dual tones are detected if one of
their components is between 400 and 500
Hz. If both components are in this range, set
a lower detection value. Set 0 for 400 Hz and
10 for 500 Hz.
This setting does not affect the single tone
detection, which always works between 300
and 550 Hz.
The longest ringing period pause must be in
the interval between parameters 952 and
953.
Warning! As these parameters also
detect incoming calls, an incorrect setting
may result in the intercom not answering the
call!
