The standard equipping package of the SIC-1ADSL includes the regular telephone
cable(s). You can separately order an external splitter as needed.
Connecting the Interface
Cable
In G. Lite mode, no splitter is needed. You can directly connect the router to the
PSTN using a telephone cable, and simply connect the phone-set in parallel with
the router at the cable distribution box.
In full rate mode, a splitter is required. Follow these steps to connect the cables:
Step 1: Plug one end of a telephone cable into the ADSL port on the router, and
the other end into the internal ADSL port on the splitter.
Step 2: Connect the telephone to the phone port on the splitter with another
telephone cable.
Step 3: Connect the external ADSL port on the splitter to the PSTN with a third
telephone cable.

SIC-1ADSL-I
Introduction SIC-1ADSL-I, the 1-port ADSL over ISDN interface card, uses the RJ-11 connector
for the WAN interface. It allows a LAN subscriber to connect to the DSLAM at the
central office over a regular analog subscriber line or telephone line. Thus, the
subscriber can access the ATM/IP backbone or the Internet to enjoy services such
as high-speed data communication and video on demand (VoD).
