Step 3
On the network map, right-click a span adjacent to the node you are logged into. A shortcut menu
Step 4
appears.
From the shortcut menu, click Circuits. The Circuits on Span window appears.
Step 5
Verify that the total number of active STS circuits does not exceed 50 percent of the span bandwidth. In
Step 6
the Circuits column there is a block titled "Unused." This number should exceed 50 percent of the span
bandwidth.
Note
Caution If the upper STSs are in use, this procedure cannot be completed. Bandwidth must be 50 percent
unassigned to convert to a BLSR. Refer to local procedures for relocating circuits if these requirements
are not met.
