TIME DIVIDED SWITCHING AND CONCENTRATION APPARATUS

摘要

Switching apparatus is disclosed having a time divided switching network for use in switching time division multiplexed channels employing PCM code? The network employs two data memories for selectively storing received PCM codes in locations associated with specific transmission channels. These memories are addressed alternately by sequential addressing apparatus and additional memory apparatus which store selected addressing codes. These addressing codes are determined by a control unit to effect shifts in the channel assignments of respective codes by selectively tranferring such codes between the data memories, thereby effecting the necessary time divided connections.
