Abstract

A digital telecommunications switching system includes a main normal rate switch having multiple, bi-directional ports for selectively switching timeslot associated with normal rate channels multiplexed on incoming and outgoing digital links. Each timeslot in the frame includes a predetermined number of bits. The normal rate switch switches times-lots received from any one of the switch ports to any one of the other switch ports at the normal rate. An "add-on" subrate switch is modularly connected to the normal rate switch and selectively switches one or more bits corresponding to one or more subrate channels within a timeslot at a data transmission rate which is less than the normal rate.
