Abstract

1417034 Automatic exchange systems TELEFONAKTIEBOLAGET L M ERICSSON 8 Feb 1973 [8 Feb 1972 (5)] 6347/73 Heading H4K In a TDM exchange incorporating a timespace-time network through which PCM channels are switched preferably in a parallel format, the addresses of an incoming channel, of an outgoing channel, of the links carrying these channels and of a connection time slot allocated for use by the two channels are initially registered in a buffer store. Thereafter they are inserted into control memories in each of the time switches after passage via the space switch during respective time slots reserved for writing control information into these memories. The particular description is identical to that of Specification 1,417,033.
