Interface cable
The interface cables that the SIC-1ADSL uses regular telephone cables.
The standard equipment 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 connect the router to the PSTN by using a telephone
cable, and 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:
Step1 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.
Step2 Connect the telephone to the phone port on the splitter with another telephone cable.
Step3 Connect the external ADSL port on the splitter to the PSTN with a third telephone cable.
