Abstract

1417035 Automatic exchange systems TELEFONAKTIEBOLAGET L M ERICSSON 8 Feb 1973 [8 Feb 1972 (5)] 6348/73 Heading H4K In a TDM exchange incorporating a timespace-time network through which PCM channels are switched, preferably in a paralle format, incoming and outgoing PCM speech words are respectively cyclically written-in and read-from respective word memories during the first half of a time slot and are respectively acyclicly read-out and written-in the respective word memories during the second half of a time slot. The address, of an outgoing link to which a word must be directed through the space switch, precedes the word during the first half of each connection time slot. The particular description is identical with that of Specification 1,417,033.
