Chapter 5 Create Circuits and VT Tunnels
Apply to drop ports—Check this check box if you want to apply the state chosen in the State field
•
to the circuit source and destination ports. CTC will apply the circuit state to the ports only if the
circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the
circuit, the circuit must be the first circuit to use port. If not, a Warning dialog box displays the ports
where the circuit state could not be applied. If the check box is unchecked, CTC will not change the
state of the source and destination ports.
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 on protected 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 and ports as source and destination choices.

switches.
If you selected Fully Protected Path, choose a Node-Diverse Path option:
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.
Step 12 If you selected Fully Protected Path and the circuit will be routed on a path protection dual ring
interconnect (DRI), check the Dual Ring Interconnect check box.
