Chapter 6 Create Circuits and VT Tunnels
NTP-A314 Create a Unidirectional OC-N Circuit with Multiple Drops
Step 17 Complete the “DLP-A369 Provision an OC-N Circuit Route” task on page 20-53.
Step 18 Click Finish. After completing the circuit, 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. The Edit Circuit window appears with the General tab selected. All nodes in the DCC
network appear on the network map. Circuit source and destination information appears under the source
and destination nodes. To see a detailed view of the circuit, click Show Detailed Map. You can rearrange
the node icons by pressing Ctrl while you 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, define the new drop:
a. Node—Choose the target node for the circuit drop.
b. Slot—Choose the target card and slot.
c. Port, STS—Choose the port and/or STS from the Port and STS drop-down lists. The choice in these
menus depends on the card selected in Step b. See Table 6-2 on page 6-3 for a list of options.
d. The routing preferences for the new drop match those of the original circuit. However, if the
following options are available, you can modify them:
• If the original circuit was routed on a protected path protection path, you can change the nodal
diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only.
See Step 13 for option 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 PCA option.
e. If you want to change the circuit state, choose the circuit state from the Target Circuit Admin State
drop-down list. The state chosen applies to the entire circuit.
f. Check Apply to drop ports if you want to apply the state chosen in the Target Circuit Admin State
to the circuit source and destination drops. For the requirements necessary to apply a service state
to drop ports, refer to the Cisco ONS 15454 Reference Manual.
g. Click Finish. The new drop appears in the Drops list.
Step 24 If you need to create additional drops on the circuit, repeat Steps 21 through 23.
Step 25 Click Close. The Circuits window appears.
Step 26 Verify that the new drops appear in the Destination column for the circuit you edited. If they do not
appear, repeat Steps 22 through 25, making sure all options are provisioned correctly.
Step 27 Complete the “NTP-A62 Test OC-N Circuits” procedure on page 6-51.
Stop. You have completed this procedure.
