Abstract: A time division multiplex (TDM) switching network for a telecommunications system or the like is described. The network contains switching network units for causing time slots formed on connected TDM lines to be assigned on a space/time division basis. The TDM lines are formed into trunk groups, and the trunk groups, respectively, form the row and column lines of a matrix. The switching network units are arranged at the crosspoints of the trunk groups to form the crosspoint switching elements between the intersecting trunk groups or between lines of the same trunk group. Each switching network unit is constructed to have a capacity for completing a number of connections less than the number of connections the crosspoint with which it is associated is capable of carrying.

Abstract: A PCM TDM switching network has a time-space-time structure composed of switch-through units which, being interlaced and released on a time basis, each operate a plurality of TDM transmission lines and TDM intermediate lines which connect the switch-through units to one another. The units effect both the time-wise and spatial assignment of time channels seized on incoming TDM lines to time channels seized on outgoing TDM lines by means of time slot conversion. The TDM transmission and the TDM intermediate lines are, in each case, connected as groups, by way of separate concentrator and distributor circuits and super-multiplex lines connected thereto which carry the interlaced items of information to the transmission memory of the relevant switch-through unit. The concentrator and distributor circuits which are assigned to the TDM transmission lines comprise cyclically operated multiplexers and demultiplexers, whereas the concentrator and distributor circuits assigned to the TDM intermediate lines are operated acyclically and their interlacing and release arrangement is modified only in the event of changes to the switching network.

Abstract: A timing circuit for use in pulse code modulation, time division multiplex switching networks is described. The switching networks are a part of a time division multiplex telecommunication system wherein each call uses the same time slot on the incoming and outgoing lines. The timing circuit has a number of word-organized storage locations equal to the number of PCM words per pulse frame and an equal number of address memory locations individually assigned to the aforementioned storage locations. The word-organized storage locations are found by blocks of shift registers connected in series. Each block in the series is connected over the non-operating positions or rest positions of pairs of simultaneously actuated switches to the next succeeding block. In their operating positions the switches connect the shift registers to the conductors of a service trunk system. The address memory locations are formed from a second series-connected shift register group connected to form a ring. Bit comparators compare the contents of the second shift register stages to a timing circuit carrying the time position code identifying the time slot in question. When all the bits of the time position code are equal to corresponding bits of the time slot address, the control inputs of the pair of aforementioned switches located at the output of the allocated word-organized storage are actuated, changing these switches to their operating positions.
