Chapter 5 Create Circuits and VT Tunnels
Auto-ranged—Unavailable for VT tunnels.
•
State—Choose a service state to apply to the VT tunnel:

Click Next.
Step 6
In the Circuit Source area, choose the node where the VT tunnel will originate from the Node drop-down
Step 7
menu.
Click Next.
Step 8
In the Circuit Destination area, choose the node where the VT tunnel will terminate from the Node
Step 9
drop-down menu.
Click Next.
Step 10
In the Circuit Routing Preferences area, uncheck Route Automatically.
Step 11
Step 12 Click Next. In the Route Review and Edit area, node icons appear to route the tunnel. The circuit source
node is selected. Green arrows pointing from the source node to other network nodes indicate spans that
are available for routing the tunnel.
Complete the
Step 13
creating. The Circuits window displays.
Verify that the tunnel you just created appears in the circuits list. VT tunnels are identified by VTT in
Step 14
the Type column.
Stop. You have completed this procedure.

IS—The VT tunnel is in service.
OOS—The VT tunnel is out of service. Traffic is not passed on the circuit.
OOS-AINS—The VT tunnel is in service when it receives a valid signal; until then, the circuit
is out of service.
OOS-MT—The VT tunnel is in a maintenance state. The maintenance state does not interrupt
traffic flow; it suppresses alarms and conditions and permits loopbacks. Use OOS-MT for
testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS
when testing is complete. See the
Inter-domain (UCP) SLA—If the tunnel will travel on a unified control plane (UCP) channel,
enter the service level agreement number. Otherwise, leave the field set to zero.
