The interface cables that the ROUTER 1/2-PORT ADSL FIC uses are regular
telephone cables.

a telephone cable, and simply connect the phone-set in parallel with the router at the
cable distribution box.
Full rate mode requires a splitter. 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.
