alternate paths), and the path diversity options apply only to path protection segments, if any exist.
To create an unprotected circuit, uncheck Fully Protected Path and continue with

check Protection Channel Access, click Yes on the Warning dialog box, and then continue with
Step
Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR
switches.
Step 11 If you selected Fully Protected Path, choose one of the following:
• Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection
portions of the complete circuit path are nodally diverse.
• Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not
possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
• Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path
protection portions of the complete circuit path are needed. The paths may be node-diverse, but CTC
does not check for node diversity.
If you selected Fully Protected Path and the circuit will be routed on a path protection dual ring
Step 12
interconnect (DRI), check the Dual Ring Interconnect check box.
Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit manually.
Step 13
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.
Complete the

are creating.
Click Finish. After completing the circuit, CTC displays the Circuits window.
Step 15
On the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and
Step 16
Search radio buttons become active.
Click Edit. The Edit Circuit window appears with the General tab selected. All nodes in the DCC
Step 17
network appear on the network map. Circuit source and destination information appears under the source
and destination nodes. To display a detailed view of the circuit, click Show Detailed Map. You can
rearrange the node icons by selecting the node with the left mouse button while simultaneously pressing
Ctrl, then dragging the icon to the new location.
Step 18 On the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.
Click Create.
Step 19
On the Define New Drop dialog box, define the new drop:
Step 20
Node—Choose the target node for the circuit drop.

Slot—Choose the target card and slot
b.
Port, STS—Choose the port and/or STS from the Port and STS drop-down menus. The card selected
c.
in Step b determines whether port, STS, or both display. See
options.
