ZyXEL modems support the extended AT command set and are compatible with
most communication software packages. However, there are some unique features in
the ZyXEL modem and there are a few unique commands to control them.
Some communication packages need a file with information about the commands
and features the modem supports. Basic information on how to set up communica-
tion software can be found in chapter 20 (THE FIRST CONNECTION). Informa-
tion and sample data files for popular communication software packages are
available in the Application Driver Area of the ZyXEL BBS (+886-35-787045).
Connecting To Your Phone
If you would like to use a single phone line for voice and modem connections, re-
move your phone cable from the RJ11 junction box and plug one end of the RJ11
cable (supplied with the modem) into the phone junction box on the wall, then plug
the other end of the cable into the rear panel of the modem labeled
DIAL-UP LINE
or WALL . Finish by plugging your phone cable into the rear panel of the modem la-
beled PHONE . Please refer to the illustrations in chapter 3 (MODEM INSTALLA-
TION).
Dial-Up Or Leased Line
The 2864 and Omni 288 models may connect to 2-wire dial-up or leased lines only.
The 2864L offers you a choice of connecting to 2-wire dial-up lines (more common-
ly known as public lines) and 2/4-wire leased lines. To use the 2864L on a leased line,
you must order and install a USOC JM8 jack. You must also specify 4-wire opera-
tion without TEK leads for the wiring option. When setting up a pair of modems
for leased line point-to-point operation, one modem must be configured for origi-
nate mode and the other for answer mode. Both RJ11C and JM8 cables are supplied
for your convenience.
