A.2 Telephone wire
Standard telephone wire of any gauge or type-flat, twisted or quad is used to connect the Modem 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. ( Figure A-4 )
