Client-layer protection schemes for the ONS 15200 are:

•SONET/SDH ADM rings—Traffic travels in two directions between any two nodes. If one route fails, the alternate route continues to transport the traffic.

•Client-layer 1+1 APS—Two separate connections exist between two client-layer interfaces. One of the connections is standby and is used only when the active connection fails.

•Layer 3 load sharing—Two routes transport traffic from one client to a dual home node (see Chapter 2, “Product Configurations” for a description of the dual home node configuration). The routes are used below their maximum capacity. If one of the two routes fails, the traffic shifts to the other route.

1.2.3Software Configurable Protection

In Release 1.1, the 2R/3R (unclocked/clocked) Client Layer Interface Port (CLIP) module is user configurable for unprotected or fiber protected operation.
