ABSTRACT:
The invention provides switching arrangments for use in digital telecommunications exchange systems for local subscriber access and comprises a selector means (PUBS) which is arranged to interface between a plurality of time division multiplex highway groups (G0 to G3) and a plurality of channel digital traffic paths (C0 to C5). The selector means (PUBS) is microprocessor controlled (MCI) to effect a plurality of different switching connectivity modes enabling bothway communication between various combinations of the time division multiplex highway groups and the channel traffic paths when the input and output data rates (1 Mbit/sec, 64 Mbit/sec or 32 Mbit/sec) of the particular connectivity mode is either compatible or incompatible.
