2.4.9 Path Protection to Four-Fiber BLSR Connection Example (ONS 15454)

2.4.9 Path Protection to Four-Fiber BLSR Connection Example (ONS 15454)
Ring 1 = Path Protection
Ring 2 = Four-fiber BLSR
This example uses the west span of the four-fiber BLSR (Ring 2) for the active path of the circuit. The
example also assumes that the four-fiber BLSR travels over OC-192 spans, as shown in
Figure 2-43

Use the command ENT-CRS-STS1:CISCO:STS-1-1&STS-2-1&STS-5-190:CTAG6::2WAY;
to create a selector between 1/1/1 and 2/1/1 to Ring 2 (5/1/190), as shown in
Figure 2-44
1/1/1
5/1/190
The command also creates a bridge from 5/1/190 to Ring 1 (1/1/1 and 2/1/1), as shown in
