Title: Signalling supervision unit in automatic telecommunication exchange
IPC: H04J3/12
Filed: 1970-02-11
Abstract: 1,269,888. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRICCORP. 11 Feb., 1970 [19 Feb., 1969], No. 6627/70. Heading H4K. In a programme controlled PCM, TDM exchange of the general type described in Specification 1,261,599 signalling data in respect of a channel is incorporated in a selected digit position of certain words on each channel and each junction has an associated last-look memory for assessing the data. In practice, the signalling bits i.e. successive Is, successive 0s or alternate 1, 0s occupy the first bit of the channel words in alternate time frames, the signalling data indieating free, busy or called party reply. Each channel of the junction has a half row in the junction's last look memory which forms part of a cyclically addressed memory associated with a group of junctions. Each half row contains seven digits of which the first four record the last state and a state change indication while the last three denote the nature e.g. incoming or outgoing, of the junction and also whether or not the received signalling data should be sent on to the next exchange. Changes of state, which are assessed for accuracy over 16 successive data signalling frames i.e. 32 successive message frames, are passed to the common marker for action. The marker may modify the contents of the last look memory. The operation of the system is described in logic terms with reference to Figs. 5-8 (not shown). Fig. 4 is a simplified version of the system described in the earlier  specification. In essence, the 24, serial 8-bit PCM channels on eight 4-wire junctions (G1) are converted into 192 8-bit parallel channels whose contents are stored in a memory MDG1. This memory is read cyclically and synchronously with a similar memory in a junctor MDJ, with simultaneous operation of crosspoints in the two stage space network SW, whereby a two way transmission between the junction group G1 and the junctor occurs (the return data from MDJ passing to demultiplexer DXG1). Thereafter during a time slot associated with the channel on the called junction e.g. one junction in group G2, a similar exchange of data occurs between MDG2 and MDJ and between MDJ and a demultiplexer DXG2, i.e. a parallel/serial converter, associated with MDJ. The crosspoints are controlled by memories MSA (called) and MSS (calling side). The signalling bits are additionally stored in a further memory (not shown) associated with G1 for subsequent processing as outlined above.
