NTP- D139 Create a Half Circuit on an MS-SPRing or 1+1 Node
–
Locked,disabled
—Puts the circuit cross-connects in the Locked-enabled,disabled service state.
Traffic is not passed on the circuit.
–
Unlocked,automaticInService
—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; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the
“DLP-D230 Change a Circuit State” task on page 19-26
For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter
in the
Cisco ONS 15454 SDH Reference Manual

•
Apply to drop ports—Select this check box if you want to apply the state chosen in the State field
to the circuit source and destination ports. CTC applies 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 the drop port. If not, a Warning dialog box shows the ports
where the circuit state could not be applied. If the box is unchecked, CTC does not change the state
of the source and destination ports.
Note
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,failed.
•
Protected Drops—Uncheck this check box if it is selected.

.
Step 9
Complete the
“DLP-D311 Provision a Half Circuit Source and Destination on an MS-SPRing or 1+1
Step 10
Click
Finish
. One of the following results occurs, depending on the circuit properties you chose in the
Circuit Creation dialog box:
•
If you entered more than 1 in Number of Circuits and selected Auto-ranged, CTC automatically
creates the number of circuits entered in Number of Circuits. If auto-ranging cannot complete all the
circuits, for example, because sequential ports are unavailable at the source or destination, a dialog
box appears. Set the new source or destination for the remaining circuits, then click
Finish
to
continue auto-ranging. After completing the circuits, the Circuits window appears.
•
If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the
Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps
through
for each additional circuit. After completing the circuits, the Circuits window appears.
Step 11
In the Circuits window, verify that the new circuits appear in the circuits list.
Stop. You have completed this procedure.
