in the Cisco ONS 15454 Reference Manual.
• Apply to drop ports—Unavailable for VT tunnels.

Step 8
In the Circuit Source area, choose the node where the VT tunnel will originate from the Node drop-down

list.
Click Next.
Step 10
Step 11 In the Circuit Destination area, choose the node where the VT tunnel will terminate from the Node
drop-down list.
Click Next.
Step 12
Step 13 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 tunnel 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 VT tunnel route before
•
the circuit is created.

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
A VT tunnel automatically transitions into the IS service state after a VT circuit is created.
