A reduction in multiplex signal lines is obtained if all the channel units in subscriber line units (7b-11b) and all the line interface units (12b-14b) are no longer connected to each multiplex line but if groups of subscriber line units (7b-8b; 9b-10b; 11b) and all the line interface units (14b-16b) are in each case connected via an "incoming" (36a, 36b) and an "outgoing" (35a, 35b) voice/data multiplex signal line to a voice/data switching network (29) and via an "incoming" (38a, 38b) and an "outgoing" (37a, 37b) signal multiplex signal line to a signal switching network (30). …<??>A flexible multiplexer provides the possibility for connections between subscriber line units, grouping and separating of multiplex signals between subscriber line units and line interface units and channel distribution between line interface units. …<IMAGE>… |
