 Fax
guard-2000 is a system that can be installed at any facsimile machines on
the market with group 3 communication. The system guards that all in and
out going information follows the standard protocol for fax communication.
If any other unknown protocol or information transmits over the line to
the facsimile machine the system break the line to the fax and gives an
alarm to the user and lights up the ALARM diode.
When this alarm occurs the system will keep the line open until the operator
resets the system with the physical key on the front of the system. The
system erase automatically all customer specified codes in the NSF block
in the hand shake protocol.
If special codes need to be transmitted in the NSF block these can be installed
in the system and then it only will approve this specific NSF codes.
The system is installed between the line and the fax machine. The LINE input
shall be connected to the line and the FAX input shall be installed to the
fax machine.
To start the guard function turn the physical key so the POWER light diode
is light up and the system is ready to guard the fax communication.
