DLP-D357 Verify Pass-Through Circuits
Step 1 In the CTC Circuits window, choose a circuit that passes through the node that will be removed and click
Edit.
Step 2 In the Edit Circuits window, check Show Detailed Map.
Step 3 Verify that the circuits have the same east and west port VC4, VC3, VC11, and VC12 mapping. For
example, if the circuit west port mapping is s5/p1/V1 (Slot 5, Port 1, VC4 1), verify that the east port is
also VC4 1. If the circuit has different east/west VC4s and/or VC3, VC11, or VC12s, record the name
of the circuit. Figure 20-13 shows a circuit passing through a node (doc-124) on the same VC4 (VC4 2).

Step 4
Repeat Steps 1 to 3 for each circuit that appears in the Circuits tab.
Step 5 Delete and recreate each circuit recorded in Step 3. To delete the circuit, see the “DLP-D27 Delete
Circuits” procedure on page 17-21. To create the circuit, see Chapter 6, “Create Circuits and Low-Order
Tunnels.”
Step 6 Return to your originating procedure (NTP).
Purpose This task verifies that circuits passing through a node that will be removed
enter and exit the node on the same VC4 and/or VC3, VC11, or VC12.
