Note:

The standard equipping package of the Router 2-Port ADSL Over POTS MIM includes the regular telephone cable(s). You can separately order an external splitter as needed.

3.12.5 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.

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.
