This month, he discusses how to transmit the signals on a baseband optical network. He also delves into signalling and powering issues. It is becoming increasingly common to transport multiplexed telephone conversations or other data using optical transmission rather than electronic transport between switches.
Data rates are slightly higher.
Everywhere else, the equivalent interface is known as the V5.2 interface. Unfortunately, V5.2 and TR-303 are incompatible. Interfacing with the Telephone On the other side of the telephone network from the switches is the home telephone interface. Cable television engineers operating a cable telephony system must understand the basics of how signals are sent to and from the telephone instrument in the home. This month, we describe signalling between the NID and the telephone.
