Figure1-2 Optically-fiber protected channels in an ONS 15200 system

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 connectio ns exist b etw een tw o client-layer interfaces. One of

the connections is standby and is used only when the ac tiv e co nne ct ion f ail s.

•Layer 3 load sharing—Two routes transport traffic from one client to a dual hom e no de (s ee

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 rout e s f ails, the traffic shifts to the

other route.

1.2.3 Software Configurable Protection

In Release 1.1, the 2R/3R (unclocked/clocked) Client Layer Int erfa ce Port (CLIP) m odule is use r

configurable for unprotected or fiber protected operation.
