1.
Plug the phone cable from the wall jack into the modem's Line Jack.
2.
Plug the phone cable from the fax machine into the modem's Phone Jack.
3.
Power on the DTE terminal and set S38 bit 4 of the modem to 1 by sending the
command "ATS38.4=1" to the modem. This will disable the modem from receiving a fax.
4.
Set the modem autoanswer ring number to be the same as your fax machine. For
example, if you have set your fax machine to answer an incoming call after 2 rings, then you
need to set the modem with the same ring number by sending the command "ATS0=2" to the
modem.
Now when a call comes in, both the modem and fax machine will go off-hook after the same
number of rings but the line is initially connected to the modem and cut-off from the fax machine.
The modem will try to handshake on the incoming call. If it is a data call, the handshake will be
successful and a connection is made. The fax machine being cut off from the line will fail the
handshake and go on-hook after a time-out. If the modem finds that it is a fax call during
handshake, it will disconnect since S38 bit 4 is set and the fax machine will get the line. The fax
machine will handshake successfully in this case.
RECEIVE FAX IN THE BBS SYSTEM
The ZyXEL modem has the unique feature of automatic detection of data and fax calls, and can
make the BBS receive a fax on the same phone line. To make your BBS receive the incoming
FAX, you need to do the following setup change in your BBS:
1.
Add the string "#B1+FCLASS=6" to the init string. Be sure the "+FCLASS=6" command
is the last command.
2.
Change one of the connect messages in the list to "CONNECT FAX".
3.
Set the external mail string to "ZyXEL" and give it an error level.
4.
In your BBS batch file, if the error level matches the external mail, execute "rcvfax 2
/p:comport /w:workpath".
This setting will enable the BBS to receive a fax and store it automatically.
The following is a sample setting for the FrontDoor system:
Add to the init string : X7#B1+FCLASS=6
Change connect message as:
((MODE-32))
Set external mail as:
((MODE-38))
The following is a sample setting in the "binkley.cfg" file for a Binkley system.
Init AT&FX7S0=1#B1+FCLASS=6
