Describe the SONET signal method.

What will be an ideal response?


SONET uses the Synchronous Transport Signal (STS) signal method. The STS consists of two parts: the STS payload (which carries data) and the STS overhead (which carries the signaling and protocol information). When folks talk about STS, they add a number to the end of "STS" to designate the speed of the signal. For example, STS-1 runs a 51.85-Mbps signal on an OC-1 line. STS-3 runs at 155.52 Mbps on OC-3 lines, and so on.
