PROGRAMMABLE MULTIPLEXING/DEMULTIPLEXING SYSTEM A programmable multiplexing/demultiplexing system used in a digital communication network, suitable for an ISDN to be developed. The system including a phase adjusting unit, a bit length varying unit, a start timing control unit, and a processor which variably controls the three units. The phase adjusting unit variably controls the phase of an internal clock in accordance with received data, and the thus-adjusted clock is used by the remaining two units. Whereby the bit length varying unit variably controls the bit length of the received data, and the start timing control variably controls the start timing of each transmission and reception processing carried out alternately by the processor. |
