Chapter 6 Create Circuits and VT Tunnels
NTP-A140 Create a Half Circuit on a Path Protection Node
Step 9 Complete the “DLP-A311 Provision a Half Circuit Source and Destination on a BLSR or 1+1” task on
page 20-5.
Step 10 Click Finish. One of the following results occurs, depending on the circuit properties you chose in the
Circuit Creation dialog box:
• If you entered more than 1 in the number of Circuits field and selected Auto-ranged, CTC
automatically creates the number of circuits entered in Number of Circuits. If auto-ranging cannot
complete all the circuits, for example, because sequential ports are unavailable at the source or
destination, a dialog box appears. Set the new source or destination for the remaining circuits, then
click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.
• If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the
Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5
through 9 for each additional circuit. After completing the circuits, the Circuits window appears.
Step 11 In the Circuits window, verify that the new circuits appear in the circuits list.
Step 12 Complete the “NTP-A135 Test Electrical Circuits” procedure on page 6-36 or “NTP-A62 Test OC-N
Circuits” procedure on page 6-51, as applicable. Skip this step if you built a test circuit.
Stop. You have completed this procedure.
NTP-A140 Create a Half Circuit on a Path Protection Node
Step 1 Complete the “DLP-A60 Log into CTC” task on page 17-66 at the node where you will create the circuit.
If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit,
complete the “DLP-A314 Assign a Name to a Port” task on page 20-8. If not, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
Step 5 In the Circuit Creation dialog box, complete the following fields:
• Circuit Type—For DS-1 circuits, choose VT. VT cross-connects will carry the DS-1 circuit across
the ONS 15454 network. For DS-3 or OC-N circuits, choose STS. STS cross-connects will carry the
DS-3 circuit across the ONS 15454 network.
• Number of Circuits—Enter the number of circuits you want to create. The default is 1.
• Auto-ranged—Uncheck this check box; it is automatically selected if you enter more than 1 in the
Number of Circuits field.
Step 6 Click Next.
Purpose This procedure creates a DS-1, DS-3, or OC-N circuit from a drop to an
OC-N line card on the same path protection node.
