to connect the Converter to the telephone network. A telephone cable
typically consists of three pairs of wires, one of which is used for
transmission. The connector at the end of the telephone cable is called an
RJ-11 connector and it consists of six pins. POTS (plain old telephone
services) use pins 3 and 4 for voice transmission. A telephone cable is
shown below.
