Log into one of the nodes that you want to convert from a point-to-point or ADM to a BLSR. See the
Step 1
"DLP-B60 Log into CTC" task on page 2-23
Check for alarms and conditions. See the
Step 2
task on page 12-3
Right-click a span adjacent to the node you are logged into.
Step 3
From the popup window, click Circuits. The Circuits on Span window appears.
Step 4
Verify that the total number of active STS circuits does not exceed 50 percent of the span bandwidth. In
Step 5
the Circuits column there is a block titled "Unused." This number should exceed 50 percent of the span
bandwidth.
Note
Warning If the first half of the capacity is exceeded, this procedure cannot be completed. Bandwidth must be
50 percent unassigned to convert to BLSR. Refer to local procedures for relocating circuits if these
requirements are not met.
