Before You Begin
if you are creating many VC low-order path circuits from the same source and destination. VC low path
Tunnel can carry 21 VC12 circuits. Refer to the "Circuits and Tunnels" chapter in the
Cisco ONS 15310-MA SDH Reference Manual for more information.
Step 1 Complete the

If you want to assign a name to the tunnel source and destination ports before you create the circuit,
Step 2

From the View menu, choose Go to Network View.
Step 3
Click the Circuits tab, then click Create.
Step 4
In the Circuit Creation dialog box, choose VC low-order path Tunnel from the Circuit Type list.
Step 5
Step 6 Click Next.
Step 7 Define the circuit attributes:
• Name—Assign a name to the VC low-order path tunnel. The name can be alphanumeric and up to
48 characters (including spaces). Circuit names should be 44 characters or less if you want the
ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the
tunnel.
Size—Unavailable for VC low-order path tunnels.
•
Bidirectional—Unavailable for VC low-order path tunnels.
•
State—Choose the administrative state to apply to all of the cross-connects in a circuit:
•

–
–

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
A VC low-order path tunnel automatically transitions into the unlocked service state after a
VC low-order path circuit is created.
