Chapter 5 Create Circuits and VC Low-order Path Tunnels
Before You Begin
–
unlocked —Puts the circuit cross-connects in the unlocked-enabled service state.
– locked, disabled —Puts the circuit cross-connects in the locked-enabled,disabled service state.
Traffic is not passed on the circuit.
–
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 17-15 .
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 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.
•
Protected Drops—Check this check box if you want the circuit routed to protected drops only, that
is, to ports that are in 1+1 protection. If you check this check box, CTC displays only protected cards
as source and destination choices.
Step 8
If the circuit will be routed on a path protection configuration, complete the “DLP-H57 Provision Path
Protection Selectors During Circuit Creation” task on page 16-75 .
Step 9 Click Next .
Step 10
Complete the “DLP-H63 Provision an STM-M Circuit Source and Destination” task on page 16-81 for
the optical circuit that you are creating.
Step 11 In the Circuit Routing Preferences area, choose Route Automatically . Two options are available; choose
either, both, or none based on your preferences.
•
Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or
exclude in the CTC-generated circuit route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path
of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans
are not in the working or protect path of the circuit.
•
Review Route Before Creation—Check this check box to review and edit the circuit route before the
circuit is created.
Step 12 To set the circuit path protection, complete one of the following:
