ABSTRACT:
An integrated telephone transmission and switching system operating in a multiframe format where each frame consists of a plurality of time slots and includes a base switch connected to a plurality of multitime slots data buses where the base switch operates to switch encoded data between any specified time slots on any of the buses. A subscriber switch is connected between a plurality of subscriber lines and to a pair of multitime-slot data buses and operates to connect and concentrate the local subscriber lines to the specified time slots on the pair of data buses, thereby enabling connections between a local subscriber line and any other subscriber line connected to the system.
