Abstract

1417036 Automatic exchange systems TELEFONAKTIEBOLAGET L M ERICSSON 8 Feb 1973 [8 Feb 1972 (5)] 6349/73 Heading H4K In a TDM exchange incorporating a timespace-time network through which PCM channels are switched preferably in a parallel format, the space switch consists of a matrix each of whose inlets has an associated register/decoder for storing, during the first half of each time slot, the address to which a PCM word occurring in the second half of each slot must be directed, so as to actuate the relevant cross-point gate during the time slot. The particular description is identical to that of Specifications 1,417,033, 1,417,034, 1,417,035 and 1,417,037.
