Abstract

PURPOSE:To constitute economically a relatively-small-scale time-division switchboard for a time-division switching system, by combinationally using parts. CONSTITUTION:The time-division switchboard is so constituted that information on digital common bus 19 coded and time-division-multiplied by A/D converter 13 including local decoder 14 is decoded by local decoder 14 controlled at the timing when local decoder 14 of A/D converter 13 is not used for coding and a PAM signal obtained by the decoding is outputted by being selected by the PAM selector circuit. As a result, local decoder 14 can be used both for coding and decoding, and its decoding operation timing is controlled independently of coding operation timing, so that the switch function can be shared partially.
