24365d85ca Therefore, MS-SPRings are suited for distributed node-to-node traffic applications such as interoffice networks and access networks. SubNetwork Connection Protection is a per path protection. For example, make the east port the farthest slot to the right and the west port the farthest slot to the left. CTC determines that the shortest route between the two nodes passes through Node 8 and Node 7, shown by the dotted line, and automatically creates cross-connections at Nodes 3, 8, 7, and 9 to provide the primary circuit path. A single ONS15600SDH node might be a part of several ONS15454 SDH rings/networks. All rights reserved. Figure7-9 shows an ONS15600SDH with multiple subtending rings. 7.5Extended SNCP Mesh Networks In addition to single MS-SPRings, SNCPs, and ADMs, you can extend ONS15600SDH traffic protection by creating extended SNCP mesh networks. Single nodes are installed at geographic locations where several ONS15454 SDH topologies converge.
Figure7-5 MS-SPRing Bandwidth Reuse 7.2.2MS-SPRing Fiber Connections Plan your fiber connections and use the same plan for all MS-SPRing nodes. SNCP is a network protection mechanism for SDH networks providing path protection (end-to-end protection). 7.1Linear ADM Configurations You can configure ONS15600SDH nodes as a line of add/drop multiplexers (ADMs) by configuring one STM-N port as the working path and a second port as the protect path. At node A, signals from these two routes are continuously monitored for path layer defects and the better quality signal is selected. Assume a failure free state for a path from a node B to a node A. If notability cannot be established, the article is likely to be merged, redirected, or deleted. Two MS-SPRings, Ring 1 and Ring 2, are provisioned on Node4. Working traffic (VC4s 1 to travels in one direction on one fiber and in the opposite direction on the second fiber. The changeover criteria are specified individually when configuring a network element.
