Chapter 6 Create Circuits and Low-Order Tunnels
NTP- D336 Create a Unidirectional Low-Order VC11 Circuit with Multiple Drops
–
VC4 grooming node is destination-node, VC11 grooming node is source-node—Creates the
LAP on the VC11 circuit destination node. This option is available only if the VC11 circuit
terminates on an STM-N card.
• None—Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only
available option if CTC cannot create a low-order tunnel or LAP.
Step 16 Click Next. In the Route Review and Edit area, node icons appear so you can route the circuit manually.
The circuit source node is selected. Green arrows pointing from the source node to other network nodes
indicate spans that are available for routing the circuit.
Step 17 Complete the “DLP-D187 Provision a Low-Order VC11 Circuit Route” task on page 18-74 for the VC11
circuit you are creating.
Step 18 Click Finish. CTC completes the circuit and the Circuits window appears.
Step 19 In the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and
Search buttons become active.
Step 20 Click Edit (or double-click the circuit row). The Edit Circuit window appears with the General tab
selected.
All nodes in the DCC network appear on the network. Circuit source and destination information appears
under the source and destination nodes. To see a detailed view of the circuit, click Show Detailed Map.
To rearrange a node icon, select the node, press Ctrl, then drag and drop the icon to the new location.
Step 21 In the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.
Step 22 Click Create.
Step 23 In the Define New Drop dialog box, create the new drop:
a. Node—Choose the target node for the circuit drop.
b. Slot—Choose the target card and slot.
c. Port, VC4, VC3/TUG3, TUG2, VC11—Choose the Port, VC4, VC3/TUG3, TUG2, or VC11 from
the Port, VC4, VC3/TUG3, TUG2, or VC11 drop-down lists. The card selected in Step b determines
the fields that appear. See Table 6-3 on page 6-4 for a list of options.
d. The routing preferences for the new drop match those of the original circuit. However, you can
modify the following:
• If the original circuit was routed on a protected SNCP path, you can change the nodal diversity
options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See
Step 13 for descriptions.
• If the original circuit was not routed on a protected path, the Protection Channel Access option
is available. See Step 12 for a description of the Protection Channel Access option.
e. Click OK. The new drop appears in the Drops list.
Step 24 If you need to create additional drops for the circuit, repeat Steps 22 and 23 to create the additional drops.
Step 25 Click Close. The Circuits window appears.
Step 26 Verify that the new drops appear in the Destination column for the circuit that you edited. If they do not
appear, repeat Steps 5 through 25, making sure that all options are provisioned correctly.
Step 27 Complete the “NTP-D135 Test Low-Order Circuits” procedure on page 6-53. Skip this step if you built
a test circuit.
Stop. You have completed this procedure.
