–
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—Check this 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 8
Complete the
“DLP-D218 Provision SNCP Ring Selectors During Circuit Creation” task on page 19-17
Step 9
Click
Next
.
Step 10
Complete the
“DLP-D312 Provision a Half Circuit Source and Destination on an SNCP Ring” task on
.
Step 11
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 the Number of Circuits field, 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 12
In the Circuits window, verify that the new circuits appear in the circuits list.
Step 13
Complete the
“NTP-D135 Test Low-Order Circuits” procedure on page 6-53
. Skip this step if you built
a test circuit.
Stop. You have completed this procedure.
