Diagnostic—Leave unchecked.
•
State—Choose the administrative state to apply to all of the cross-connects in a circuit:

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter
in the Cisco ONS 15454 Reference Manual.
• Apply to drop ports—Check this check box if you want 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 must be the first circuit to use the port. If not, a Warning dialog
box displays the ports where the administrative state could not be applied. If the check box is
unchecked, CTC does not apply the administrative state of the source and destination ports.
Note
Protected Drops—Check this box if you want the circuit routed to protect drops only, that is, to
•
ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC
displays only protected cards as source and destination choices.

IS—Puts the circuit cross-connects in the IS-NR service state.
OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is
not passed on the circuit.
IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses
alarms and conditions. When the connections receive a valid signal, the service state
automatically changes to IS-NR.
OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT 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 OOS,MT for circuit testing or to suppress circuit alarms
temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is
complete. See the "DLP-A230 Change a Circuit Service State" task on page
Loss of signal alarms are generated if ports in the IS-NR service state are not receiving
signals.
