Create Circuits and VC Low-order Path Tunnels
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter
in the Cisco ONS 15310-MA SDH Reference Manual.
Apply to drop ports—Check this check box to apply the administrative state chosen in the State field
to the circuit source and destination ports. CTC applies the administrative 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 is the first circuit to use the port. If not, a Warning dialog box shows the ports
where the administrative state could not be applied. If the check box is unchecked, CTC does not
change the service state of the source and destination ports.
Note
Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is,
to ports that are in 1+1 protection. If you check this check box, CTC displays only protected cards
as source and destination choices.
If the circuit will be routed on a path protection configuration, complete the

any exist.

If you selected Fully Protected Path in
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 might be node-diverse, but
CTC does not check for node diversity.

Automatic In Service—Puts the circuit cross-connects in the
unlocked-disabled,automaticInService service state and suppresses alarms and conditions.
When the connections receive a valid signal, the service state automatically changes to
unlocked-enabled.
locked, maintenance—Puts the circuit cross-connects in the locked-enabled,maintenance
service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and
conditions and allows loopbacks to be performed on the circuit. Use locked, maintenance for
circuit testing or to suppress circuit alarms temporarily. Change the administrative state to
unlocked; Automatic In Service; or locked, outOfGroup when testing is complete. See the
"DLP-H111 Change a Circuit Service State" task on page
If ports managed into the unlocked administrative state are not receiving signals, loss of
signal alarms are generated and the port service state transitions to unlocked-disabled,FLT.
