Abstract

PURPOSE:To eliminate a perfect synchronous process among slave stations, by transmitting the own information stored in a buffer memory plus the transfer information of other slave stations by each slave station based on the clock of own station. CONSTITUTION:At station A, the intraoffice information (a) supplied to an intraoffice interface part 26 is written into a buffer memory 21 according to a command of a microprocessor 24. In the same way, the intraoffice information (b) and (c) are written into buffer memories 22 and 23 at stations B and C respectively. Then the contents of buffer memories 21-23 are read successively by the command of the processor 24 based on the clock of own station for each station, and then transmitted to a line L via an output interface part 27 and a modulating circuit 28.
