Stop. You have completed this procedure.
NTP-D139 Create a Half Circuit on an MS-SPRing or 1+1 Node
Step 1 Complete the “DLP-D60 Log into CTC” task on page 17-49 at the ONS 15454 SDH where you will
create the half circuit. If you are already logged in, continue with Step 2 .
Step 2
If you want to assign a name to the circuit source and destination ports before you create the circuit,
complete the
“DLP-D314 Assign a Name to a Port” task on page 20-7 . If you want CTC to assign a name
automatically based on circuit type, node name, and sequence number, continue with Step 3 .
Step 3 From the View menu, choose Go to Network View .
Step 4
Click the Circuits tab, then click Create .
Step 5
In the Circuit Creation dialog box, complete the following fields:
•
Circuit Type—For low-order circuits, choose VC_LO_PATH_CIRCUIT . For high-order circuits,
choose VC_HO_PATH_CIRCUIT . VC4 cross-connects carry the circuit across the
ONS 15454 SDH network.
• Number of Circuits—Enter the number of circuits that you want to create. The default is 1.
•
Auto-ranged—This check box is automatically selected if you enter more than 1 in the Number of
Circuits field. Uncheck the box.
Step 6 Click Next .
Step 7
Define the circuit attributes:
•
Name—Assign a name to the circuit. 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 circuit.
•
Size—For high-order circuits, choose VC4 . For low-order circuits, choose VC11 , VC12 , or VC3 .
•
Bidirectional—Leave checked for this circuit (default).
•
Create cross-connects only (TL1-like)—Check this check box if you want to create one or more
cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order
tunnels and Ethergroup sources and destinations are unavailable.
• 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.
Purpose This procedure creates a low-order or high-order circuit from a drop card
to an STM-N trunk (span) card on the same node in an MS-SPRing or 1+1
topology.
