Pulse code modulation (PCM) is the worldwide process for transmission
of digital signals.PCM is used to transmit both signaling data and payload.
PCM is categorized into hierarchies, depending on the transmission rate.
Consider a 2Mbps PCM link be partitioned in 32 independent channels of 64kbps each
One 64-Kbps time slot out of a 2-Mbps PCM link typically is used for signaling data
A call setup consumes about 1 to 2 Kbps.
