Double Call Feature
If the AX1 system is connected to the same phone line with a fax machine, an issue of who will be
picking-up the line first wills occure. This is due to the fax machine also has its own preprogrammed
ringing count to be operated. If the RING NUM in AX1 system is lower than Fax machine, fax
machine has no chance to receive any fax and vice versa.
So, to use the double call feature Fax Machine Ring number must be less than AX1 Ring Number (but
minimum 3 ring number).
With the Double Call feature, user has option to enable the Double Call feature which enables the
AX1 system to recognize the symptom of incoming call before answer the phone. The term "double
call"is refer to the action of calling the number twice with certain condition which the AX1 system
will detect it as an instruction to pick-up the call. With this mechanism, the fax machine could be
installed to the same phone line as the AX1 system. So, if the first call‟s ring counts exceed the fax
machine‟s preprogrammed ringing count, the call will be answer by the fax machine; and if a double
call condition is detected, only then the AX1 system will answer the call.
If Double Call feature is set to DISABLE (default), system will answer the incoming call once ringing
count had been detected as per the preprogrammed number in RING NUM.
If Double Call feature is set to ENABLE, the mechanism of incoming call detection will be as show
in Flow Chart 4.3.2. The first call must be at least 2 ringing tone and shall not exceed the
preprogrammed RING NUM setting of the fax machine; and then user shall call into the system for
nd st st
the 2 time within 20s after the 1 call ended. System will answer the incoming call at the 1 ringing
tone if requirement above is fulfilled.
Perform system control through
phone.
