IPC: H04J3/14
Filed: 1990-02-14
Abstract: PURPOSE:To improve the reliability of monitoring by setting a delay bit stage number stored in a memory to a variable delay circuit when phase synchronization is taken only once in all delay bit stage number and collating the bit correspondence between the input data of a monitored circuit and the output data of a reference circuit. CONSTITUTION:When phase synchronization is taken form the plural number of times as to all delay bit stage number of a variable delay circuit 4, since pseudo synchronized pull-in state takes place, the phase synchronized pulling-in is decided to be disabled and the bit collation to monitor a circuit 1 to be monitored is not transited. Moreover, when the phase synchronization is taken only once as to the delay bit stage number of the variable delay circuit 4, it is decided to be correct phase synchronized pull-in state and the bit collation to monitor the circuit 1 to be monitored is transited. Thus, the pseudo synchronized pulling-in by the data of a short pattern period is avoided and the reliability of monitoring due to bit collation is improved.

The clock signal is extracted out of the signal train demodulated by the modulator 5 through a clock signal extracting device 8 and supplied to the demodulators 5 and 6. The signal train demodulated by the demodulator 5 is decoded to voices by a decoder 9 and sent to a telephone receiver 23. Furthermore, the signal train is compared with the signal train given from the demodulator 6 at a code comparator 10. No alarm is generated from an error pulse detector 11 if the demodulators 5 and 6 perform demodulation with no code error.
