Abstract

PURPOSE:To minimize the scale for both the device and the circuit and thus to simplify the device constitution by carrying out the reception action for both each slave station and the master station with the synchronism which is completely subject to the frame and the transmission clock of the master station. CONSTITUTION:The PCM multiplied digital call signal is transmitted via non- directional antenna 28 to plural number of slave stations containing PCM end office device 35, transmitter/receiver 30 plus control unit 38 from the master station including PCM end office device 21, transmitter/receiver 24 plus control unit 68 each. Thus the digital call signal is received at unit 38 to detect the clock and frame synchronous signals. Then based on the clock and synchronous signals allotted to the self-office, the designation channel is fitted to the transmission channel of the self-office. And the burst selection gate is transmitted to the master station. At the master station the burst selection gate is detected through unit 68 for each slave station, and both the frame synchronous signal and the clock signal are formed according to the time slot of the slave station to be applied to the carrier synchronism demodulator circuit installed for the slave station. Thus the demodulation is started from the first bit of each burst.
