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 ports
as source and destination choices.

portions of the complete circuit path are nodally diverse.

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 VC low-order path circuit source and destination ports are in an
unlocked-disabled,automaticInService; locked-enabled,maintenance; or unlocked-enabled
service state, VC low-order path circuits in unlocked-disabled,automaticInService change to
unlocked-enabled even if a physical signal is not present.
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.
