Note
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 on protected drops only, that
•
is, to ports that are in 1+1 protection. If you check this check box, CTC displays only protected cards
and ports as source and destination choices.

If the circuit will be routed on a path protection configuration, complete the

step.
Step 9 Click Next.
Step 10 Complete the
Step 11 In the Circuit Routing Preferences area, click Route Automatically. Two options are available; choose
either, both, or none based on your preferences.
• Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to
include or exclude in the CTC-generated circuit route.

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.
