Chapter 6 Create Circuits and VT Tunnels
NTP-A167 Create an STS Test Circuit around the Ring
Step 14 When routing a test circuit with source and destination ports on the same node, the Fully Protected Path
check box is automatically disabled. Choose one of the following options:
• To leave the test circuit unprotected, continue with Step 15.
• To route the test circuit on a BLSR protection channel, check Protection Channel Access, click Ye s
in the Warning dialog box, then continue with Step 15.
Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR
switches.
Step 15 Click Next.
Step 16 In the Route Review/Edit area, node icons appear for you to route the circuit manually:
a. In the Route Review/Edit area, click the source node icon if it is not already selected.
b. 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.
c. The arrow turns white. In the Selected Span area, the From and To fields provide span information.
The source STS appears. If you want to change the source STS, adjust the Source STS field;
otherwise, continue with Step d.
d. Click Add Span. The span is added to the Included Spans list and the span arrow turns blue.
e. Repeat Steps b through d until the circuit is provisioned from the source to the destination node
through all intermediary nodes.
Step 17 Click Finish. If the path does not meet the specified path diversity requirement, CTC displays an error
message and allows you to change the circuit path. If you entered more than 1 in the Number of Circuits
field, the Circuit Creation dialog box appears after the circuit is created so you can create the remaining
circuits. Repeat Steps 7 through 16 for each additional circuit.
Step 18 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created
appear in the window.
Stop. You have completed this procedure.
