2.11.4 Interface Cable
The interface cables that the SIC-1ADSL uses are regular telephone cables.
Note:
The standard equipping package of the SIC-1ADSL includes the regular telephone
cable(s). You can separately order an external splitter as needed.
2.11.5 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.
