ABSTRACT:
In a transmission station, the information from each channel is sampled and encoded to a PCM form having a predetermined length of bits. The group of said bits together with line number bits is called a signal block. Only significant signal blocks from all the channels are transmitted to a receiving station through a buffer memory provided at a transmission station and a common transmission line. The receiving station receives the signal blocks through a buffer memory provided at the receiving station and inserts an idle signal to the portion where the transmission station removes a signal block due to an insignificant signal block. The received signal blocks are distributed to each receiving channel, thus, the original signal is reproduced at the receiving station.
