Answer Signaling on FXS Port
What’s this?
• As general application, telecom equipment like PCO machine is
connected to the FXS port of the system. Now whenever the called
party (remote party) answers i.e. goes off-hook it is required to
inform the FXS port so that the PCO machine can consider the call
as matured and start billing. In absence of this signal, the call is
never considered as matured and hence no billing will be
generated.
• To avoid such problems the system supports ‘Answer Signaling’. It
is a signal which will be generated on FXS port, which indicates
that the called party has answered and the call is matured. This
helps in accurate billing, avoids billing of unanswered and
unsuccessful call attempts.
• It is generated in the form of:
• None
• Polarity (Battery) Reversal
How it works?
• Answer Signaling is applicable for OG call made from FXS.
• When call is made from FXS port to any other port, system will wait
for the call to get matured.
• When the call gets matured, the system will check the Answer
Signal programmed for the FXS. The options are as explained
below:
•
None:
This option is used when no answer signaling is to be
generated on the FXS port.
•
Polarity Reversal:
This option is used when answer signaling is
to be generated in the form of Polarity Reversal on the FXS
port. The Battery polarity of the FXS port will get reversed. For
example, if the battery polarity of the FXS port is +ve for TIP and -
ve for RING in speech condition then after call maturity, TIP will
become -ve and Ring will ve.
