Chapter 2 Procedures and Provisioning
Use the command ENT-CRS-STS1:CISCO:STS-5-1&STS-6-1,STS12-26:CTAG2::2WAY;
to create a selector between 5/1/1 and 6/1/1 which connects to 12/3/2 on Ring 2, as shown in
Figure 2-34

The command also creates a bridge from 12/3/2 to Ring 1 (5/1/1 and 6/1/1), as shown in
Figure 2-35

12/3/2
In this configuration a two-fiber BLSR switch can automatically reconnect the selector output to the
protection path on the east port (12/3/2 assuming OC-12) if necessary.

2.4.6 Two-Fiber BLSR to Path Protection Connection Example

Ring 1 = Two-fiber BLSR
Ring 2 = Path Protection
This example, illustrated in
BLSR and uses the east span of the two-fiber BLSR (Ring 1) for the active path of the circuit. For STS
addressing, the path protection is an OC-3 (for example, STS-13-8).
