| description | PCT No. PCT/GB95/00271 Sec. 371 Date Oct. 10, 1996 Sec. 102(e) Date Oct. 10, 1996 PCT Filed Feb. 10, 1995 PCT Pub. No. WO95/22860 PCT Pub. Date Aug. 24, 1995An SDH (Synchronous Digital Hierarchy) telecommunications network has a plurality of interconnected nodes (1, 2, 3, 4). Working channels (7,6) are defined between respective pairs of nodes (1,2 and 3,4) with one common protection channel (5) serving a plurality of working channels (5,6) such that in the event of a fault on a working channel traffic signals passing from a first node (3) to a second node (4) along that working channel (6) are switched onto the protection channel (7). The first node (3) is then operative to transmit a channel trace signal along with the traffic signals which serves to identify the respective channel. The second node (4) is operative to monitor for the presence of a channel trace signal on the protection channel (7) for which it is the terminating node and upon detection thereof to switch traffic signals associated with that trace signal on the protection channel (7) into the second node (4) for connection to an onward destination. |
