3 Qu ck Installat on
This Quic Installation part describes how to connect the ZXDSL 831C device to your
computer, LAN and the Internet.
This Quic Installation assumes you have subscribed to an ISP for ADSL service and
only covers the basic configurations to be applied to residential or corporate networ s.
3.1 Hardware Connect on
Recommendation: It is recommended to follow the first example in actual connection!
Note: In the circumstance where the first connection examp e is not app icab e
and you choose to use the second examp e, you must insta a MicroFi ter on the
te ephone ine (a sp itter can never be used to rep ace the MicroFi ter).
Specia attention: Insta ing a te ephone direct y before the sp itter wi ead to a
fai ure to connect to the CO side device and the Internet or s ow connection speed.
If you need to connect a te ephone to the te ephone ine before the sp itter, a
MicroFi ter is required. (Genera y, you can connect on y one MicroFi ter before
the sp itter for reducing noise.)
1. Shown as the two examples below, use a Telephone line to connect the DSL port
of ZXDSL 831C to the MODEM port of the splitter, and connect the telephone
line to the PHONE port of the splitter. Then connect the wall phone jac with the
LINE port of the splitter.
The splitter comes with three connectors as below:
LINE: Connects to a wall phone jac (RJ-11 jac )
MODEM: Connects to the DSL jac of ZXDSL 831C
PHONE: Connects to a telephone set
2. Use an Ethernet cable (straight-through or cross-over) to connect the LAN port of
ZXDSL 831C to your LAN or a PC with networ card installed.
3. Connect the power cord to the PWR connector on ZXDSL 831C, then plug in the
AC power adapter to the AC power outlet, and then press the on-off button.
