Caution
This procedure is service affecting. All circuits in the ring are deleted and reprovisioned.
Caution
Read through this procedure completely before beginning the conversion.
Note
Prior to beginning this procedure, you should have a unique ring name to identify the new BLSR and a
unique node ID number for each node on the ring.
Note
Prior to beginning this procedure, optical transmit and receive levels should be in their acceptable range
as shown in
.
Step 1
Complete the
“DLP-A60 Log into CTC” task on page 17-66

Verify that the total number of active STS circuits does not exceed 50 percent of the span bandwidth. In
the Circuits column there is a block titled “Unused.” This number should exceed 50 percent of the span
bandwidth.
Note
If the span is an OC-48, no more than 24 STSs can be provisioned on the span. If the span is an
OC-192, no more than 96 STSs can be provisioned on the span. If the span is an OC-12, no more
than 6 STSs can be provisioned on the span.
Purpose
This procedure converts a path protection to a two-fiber BLSR manually,
