A subset of this revolution is the transition from analog/waveformbased communications to digital/packetized transmissions. ” George B. Dyson, in his book, Darwin Among the Machines, elegantly states the impact of this transition: A circuit-switched communications network, in which real wires are switched to connect a flow of information between A and B, would be swamped by the intractable combinatorics of millions of computers demanding random access to their collective address space at once. All the switches in the world could never keep up.
This saves the user the effort of continually trying to reach a busy extension. A code assigned to each extension that specifies the PBX functions allowed. For example, lobby telephones may be assigned class of service 5, which allows local calls only. Each organization can define class of service to meet its needs.
