ABSTRACT:
A digital switching network in an exchange having distributed control and a central switching network, the switching network comprising a plurality of independent planes, each of which is connected via inlet and outlet multiplex links to terminal units which include means for connecting terminals to said multiplex links, wherein each plane comprises synchronized switches (CX1) each equipped with a marker (MQ1) and constituting a single switching stage, the switches being connected in parallel to the inlet links (LE) of the plane, and each switch serving a respective group of the outlet links (LS), each multiplex link serving a group of terminal units (UT) in parallel, with each group of terminal units being connected to each plane of the switching network by at least one multiplex link, each switch being modular and including a control memory circuit driven by the associated marker (MQ), and a plurality of buffer memory circuits constituting square switching matrices, each of said square switching matrices being connected to a portion of the inlet links served by the switch and to all of the outlet links served thereby.
