Interface Cable The interface cables that the SIC-1ADSL uses are regular telephone cables.

n 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 In G. Lite mode, no splitter is needed. You can directly connect the router to the Cable 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).
