Chapter 5 Create Circuits and VT Tunnels
Note
Create cross-connects only (TL1-like)—Check this check box if you want to create one or more
•
cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you
cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are
unavailable.
Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter
•
the service level agreement number. Otherwise, leave the field set to zero.
Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is,
•
to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays
only protected cards as source and destination choices.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR
switches.
If you selected Fully Protected Path, choose one of the following:
Step 11
• 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 ring interconnect
Step 12
(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 green arrows pointing from the selected node to other network nodes indicate spans that are
available for routing the circuit.
