Filed: 1987-01-28
Abstract: An improved switching apparatus, having group couplers (30) and a loop arrangement (6) including a plurality of single loop lines, for communication of digital signals, particularly PCM signals, each comprising several bits at a fixed transmission rate to or from connection circuits (35, 36) connected to a plurality of group buses (31, 32) on each of which digital signals can be transmitted in parallel in a predetermined number of time compartments in cyclic repetition in pulse frames. The group buses (31, 32) are connectable by way of a respective one of the group couplers (30) to the line segments (25, 26) of a respective main bus associated with one of the main couplers (13, 14) connected to segments (7, 87) of the central loop arrangement (6). The two line segments (25, 26) of each main bus serve to transmit digital signals in different directions. This improved apparatus considerably expands the connection facilities for the several connection circuits over earlier switching apparatus employing group couplers and a loop arrangement.
