Inventor: SAGA RIYOUKICHI
IPC: H04J3/14
Filed: 1983-09-03
Abstract: PURPOSE:To always supervise a circuit, by transmitting a pattern for supervision by inputting the pattern into a compressing buffer which converts the pattern into a burst signal and separating the pattern for supervision by expanding the burst signal to a received signal at a receiving side, and then, finding the error ratio. CONSTITUTION:A pattern for supervision is generated 13 and written in compressing buffer circuits 1-1-1-n, and then, the pattern is combined 2 with data D1-Dn under a burst-like condition and scrambled 3. At a combining circuit 4 the scrambled one is combined with a synchronizing unique word (SUW) generated from an SUW generating circuit 5 and transmitted after modulation 6. At a receiving side, the transmitted signal is demodulated 7 and distributed 8 and a part of the signal is sent to an SUW detecting circuit 9 where SUWs of its own station and a base station are detected and synchronism of time division multiple access communication is taken. The other part is descrambled 10, distributed 11, and inputted into expanding buffer circuits 12-1-12-n. Data signals and the pattern for supervision are separated from each other from the output of the expanding buffer circuits and the separated pattern is detected 14, and then, the pattern is compared with the supervising pattern 13 of an input side. Therefore, the whole system can be supervised easily.
