Abstract:
1. A multiplexing and transmission apparatus which receives low-speed frame signals from a plurality of channels in parallel and outputs a high-speed serial signal, said multiplexing and transmission apparatus comprising: a control pulses generating circuit which generates control pulses each of which corresponds to one of said channels, wherein said control pulses have different timing for each channel; channel-frame generating circuits, connected to said control pulses generating circuit, each of which receives said low-speed frame signal and outputs said low-speed frame signal in synchronization with said control pulse so that an output timing of said low-speed frame signal is shifted with respect to an output timing of other low-speed frame signals so that a receiving side apparatus can recognize a channel number of said low-speed frame signal; and a multiplexing circuit, connected to said channel-frame generating circuits, which multiplexes said low-speed frame signals into said high-speed serial signal and outputs said high-speed serial signal.
