Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
In the Circuit Creation dialog box, choose VC low-order path Aggregation Point from the Circuit Type

list.
Step 6 Click Next.
Step 7 Define the circuit attributes:
Name—Assign a name to the VC low-order path aggregation point. 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
VAP.
Size—(Display only) Displays VC4.
•
Bidirectional—(Display only) The check box is checked.
•
State—Choose the administrative state to apply to all of the cross-connects in a circuit:

For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter
in the Cisco ONS 15310-MA SDH Reference Manual.

Step 8
In the Circuit Source area, choose the source node, slot, port, and VC high-order path for the VAP. The
Step 9
VAP source is where the E1 (VC-12) circuits will be aggregated into a single VC high-order path. The
VAP destination is where the E1 circuits originate.
From the Node drop-down list, choose the node where the VAP will originate.

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