DLP- D312 Provision a Half Circuit Source and Destination on an SNCP Ring
Step 4 Complete one of the following:
• For low-order VC12 circuits, choose the VC4, TUG3, TUG2, and VC12.
• For low-order VC11 circuits, choose the VC4, TUG3, TUG2, and VC11.
• For low-order VC3 circuits, choose the VC4 and VC3.
• For high-order circuits, choose the VC4.
Step 5 Click Next.
Step 6 From the Node drop-down list, choose the node chosen in Step 1.
Step 7 From the Slot drop-down list, choose the STM-N card to map the low-order VC3, VC11, or VC12 circuit
for optical transport or to map the VC4 circuit to a synchronous transport module (STM).
Step 8 Choose the destination from the drop-down lists that appear.
Step 9 Return to your originating procedure (NTP).
DLP-D312 Provision a Half Circuit Source and Destination on an SNCP Ring
Step 1 From the Node drop-down list, choose the node that will contain the half circuit.
Step 2 From the Slot drop-down list, choose the slot containing the card where the circuit will originate.
Step 3 From the Port drop-down list, choose the port where the circuit will originate. This field might not be
available, depending on the card chosen in Step 2.
Step 4 Complete one of the following:
• For low-order VC12 circuits, choose the VC4, TUG3, TUG2, and VC12.
• For low-order VC11 circuits, choose the VC4, TUG3, TUG2, and VC11.
• For low-order VC3 circuits, choose the VC4 and VC3.
• For high-order circuits, choose the VC4.
Step 5 Click Next.
Step 6 From the Node drop-down list, choose the node chosen in Step 1.
Purpose This task provisions a half circuit source and destination on a subnetwork
connection protection (SNCP) ring. A half circuit allows you to provision
a partial path (one end of a circuit), for example, if you want to provision
a circuit with the intent that the path will be completed at a later time or at
a different location.
