ABSTRACT:
A multimodule time division switching system is disclosed in which intermodule calls are served by transmitting call information words over a bus system interconnecting all modules. Each transmitted word contains information specifying the receiving module identification number, the time slot in which the call is to be served in the receiving module, as well as the message or intelligence representing the subject matter of the call. A FIFO memory in each module is used as an input buffer to temporarily store each received word and thereby reduce the need for short term time slot synchronization between modules.
