Step 3 If you want to change the source VC-4, adjust the Source VC4 field; otherwise, continue with Step 4.
Step 4 Click Add Span. The span is added to the Included Spans list and the span arrow turns blue.
Step 5 Repeat Steps 2 through 4 until the circuit is provisioned from the source to the destination node through
all intermediary nodes. If Fully Protect Path is checked in the Circuit Routing Preferences area, you
must:
• Add two spans for each SNCP ring or unprotected portions of the circuit route from the source to
the destination.
• Add one span for each MS-SPRing or 1+1 portions of route from the source to the destination.
• Add primary spans for each MS-SPRing from the source to the destination through the primary
nodes, and then add spans through the secondary nodes as an alternative route. Protection channel
access (PCA) spans can only be chosen as part of the secondary path.
Step 6 Return to your originating procedure (NTP).
