DEVICE AND METHOD FOR 4 CHANNEL QUADRUPLE CHANNEL SETTING IN PERSONAL COMMUNICATION SYSTEM EXCHANGE

摘要

Purpose a: device and a kind of method, for establish-four times of four-way of a PCS (PCS Personal Communications System) exchanges be arranged in conjunction with the channel of an operation processing device and a channel one not-operation processing device, it simultaneously include first is that process plate duplex and duplex channel in the U-link structure of the communication channel between master processor block, to extend a channel selection range. Construction: in a transmitting device, first and second demultiplexer (22,23) transmission signal is received, the transmission signal output multi-channel decomposed signal being received according to input to the selection signal DeMux of selection signal input terminal (S1, S2) is to first to fourth channel terminal (CH1-CH4). Third and fourth signal separator (24,25) first and second demultiplexer (22 is received, 23) output signal of output end, first and second demultiplexer (22 of DeMux, 23) the output signal being received is according to selection signal, it is inputted to selection signal input terminal (S1, S2), for exporting. In a receiving portion, first and second multiplexer (27,28) signal is received by first to fourth channel terminal (CH1-CH4), the optical signals of reception signal are selected according to selection signal, it is inputted to selection signal input terminal (S1, S2), then double selected reception signal for exporting. Third and the 4th multiplexer (29,30) channel hybridization signal is received and to the first of first to fourth channel terminal (CH1-CH4) to third loopback signal, selection is according to selection signal input to one of the signal of first to fourth channel terminal (CH1-CH4), it is inputted to selection signal input terminal (S1, S2). The signal and signal output, the reception signal last as one that third and the 4th multiplexer (29,30) selectively double selected from first and second multiplexer (27,28) export multiplexed signals.
