The fax switch
External line 1 of your telephone system can be operated with fax switch function
to separate voice calls and fax messages in order to forward them to the desired
target.
Operation principle
To determine whether a message is a fax or a voice message the fax signal (CNG)
sent by a fax machine will be analysed. In order to be able to do this with every call
on external line 1 the call will be taken and the system will then wait up to 5
seconds for the CNG signal. If such a signal is detected the call will be forwarded
to your fax machine. As soon as the fax machine answers the connection will be
made and the fax transfer will start.
