Two versions in the g.711 codec are employed from the traditional digital telephone networks that happen to be based largely on 64Kbps digital telephone channels. The digital telephone channels are multiplexed together employing a method referred to as Time Division Multiplexing to create either T1 or E1 lines. A T1 line is made to carry 24 digital calls, whereas an E1 line is built to carry 30 digital phone calls. These multiplexed trunk lines are widely-used to interconnect exchanges and also connect a normal PBX (Private Branch Exchange) to your Telephone Operator's exchange.

Years ago, this became difficult, in fact, a hand-held device could pick-up telephone conversations.
