摘要: A time division multiplex transmission apparatus which transmits low-speed data and telegraph signals of a maximum n×m channels as high-speed in multiplexed manner based on system. The also separates received into signals. includes m input/output units each comprising: level converter circuit for converting the subscriber's line n to an internal logic level, first microprocessor regenerating start-stop function regenerate telex signals, programmable timer controlling interruption microprocessor, control determining priority order channel setting switch self-address transfer slot has been allotted, address decoder decoding from common bus, bus driver receiver transferring via bus; processing device second multiplexing separating m×n channels, generating detecting frame patterns keeping synchronization, adresses encoder encoding said devices bus.
