Abstract

PURPOSE:To give the flexibility of device operation and reduce the communication quantity between modules, by providing a number translation table memory, where data of subscribers are stored, in a distributed control module and by transmitting a selection signal received from a subscriber to another module. CONSTITUTION:Distributed control modules MOD-1- are connected mutually by highways JWH12-, and signal lines DL1- are connected as a common bus. The module MOD-1 is provided with a subscriber's number translation table memory 4 and a signal transmitting and receiving device 5 where a selection signal received from a subscriber is stored, and the selection number is transmitted to the signal line DL1. The selection number inputted from a shift register 6-1 and a signal line DL2-n is compared with the output of the memory 4 by comparators 7-1-7-n, and a control processing device 2 instructs a channel system 1 to select highways JHW12- through an FF group 8. Consequently, the call processing is possible for increment of the number of subscribers only by adding the memory 4, and a terminating module is discriminates.
