DLP- F343 Provision an STM-N Circuit Route
DLP-F343 Provision an STM-N Circuit Route
Step1 In the Circuit Creation wizard in the Route Review/Edit area, click the source node icon if it is not
already selected.
Step2 Starting with a span on the source node, click the arrow of the span you want the circuit to travel. To
reverse the direction of the arrow, click the arrow twice.
The arrow turns white. In the Selected Span area, the From and To fields provide span information. The
source VC appears.
Step3 If you want to change the source VC, adjust the Source VC field; otherwise, continue with Step 4.
Step4 Click Add Span. The span is added to the Included Spans list and the span arrow turns blue.
Step5 Repeat Steps 2 through 4 until the circuit is provisioned from the source to the destination node through
all intermediary nodes. If Fully Protected Path is checked in the Circuit Routing Preferences area, you
must:
•Add two spans for all SNCP or unprotected portions of the circuit route from the source to the
destination.
•Add one span for all MS-SPRing or 1+1 portions of route from the source to the destination.
•Add primary spans for MS-SPRing-DRI from the source to the destination through the primary
nodes, and then add spans through the secondary nodes as an alternative route. The circuit map
shows all span types: unprotected, MS-SPRing, and PCA. PCA spans can only be chosen as part of
the secondary path.
Step6 Return to your originating procedure (NTP).
DLP-F344 Initiate an MS-SPRing Manual Ring Switch
Purpose This task provisions the circuit route for manually routed STM-N circuits.
Tools/Equipment None
Prerequisite Procedures DLP-F181 Log into CTC, page 16-34
The Circuit Creation Wizard must be open.
Required/As Needed As needed
Onsite/Remote Onsite or remote
Security Level Provisioning or higher
Purpose This task performs an MS-SPRing Manual ring switch. A Manual ring
switch will switch traffic off a span if there is no higher priority switch
(Force or lock out) and no signal degrade (SD) or signal failure (SF)
conditions.
