Abstract
PURPOSE:To output AIS signals as plural low-order PCM signals to be used as high-order PCM signals at the time of asynchronizing by using most of an AIS signal generating circuits for high-order PCM signal to AIS signal generating circuits for low-order PCM signal in common to generate different AIS signals for plural low-order PCM signals being high-order PCM signals. CONSTITUTION:A high-order PCM multiplex signal (y) and a high-order PCMCLK y' are supplied to demultiplex circuit 14, where the signals are demultiplexed into 4-system of low-order PCM signals (a), (b), (c), (d), they are synchronized with a synchronizing circuit 15 so as to output switching signals SEL1e, SEL2f, SEL3g, SEL4h in synchronizing/asynchronizing state. Switching circuits 10, 11, 12, 13 receive lowporder PCM signals (a), (b), (c), (d) and main signal AIS(alarm information signal) signals (q), (r), (s), (t), use the switching signals SEL (e), (f), (g), (l) to select the low-order PCM signals (a), (b), (c), (d) in the synchronizing state and the main signal AIS signals (q), (r), (s), (t) in the asynchronizing state, and the result is outputted as transmission signals (u), (v), (w), (x).
