Hi there,
Just to add a note to the good tips from Alex (+5 )
Here is the related TAMB@ info for FXS disconnect;
Station Port Interfacing:
The TAMB2 answers the station port after it detects high
voltage (90V) ring on the line. The unit can be set to answer
the call immediately or after the end of the first ring burst. Once
answered, the unit provides an announcement tone and connects
the telephone line to the paging amplifier through an isolation
transformer. The announcement tone can be set to be
heard only at the paging phone or at both the phone and over
the paging system. The TAMB2 allows bi-directional audio,
both to and from the paging equipment (in the case of talkback
paging equipment). Since the TAMB2 cannot directly
determine the state of the calling partyʼs phone, it must use
indirect methods to determine when to disconnect. Disconnection
of the TAMB2 from the call is controlled through 3
methods. 1) A default timer will drop the call after a preset
amount of time has elapsed (1-200 seconds), 2) A VOX timer
will drop the call after it detects no audio for a preset amount
of time (1-11 seconds), 3) The unit will immediately drop the
line if it detects a CPC pulse (break in loop current) from the
PBX/CO port. Any of these disconnection methods can be inhibited,
however at least one must be enabled to ensure that
the TAMB2 will disconnect.
Cheers!
