Create VC LO tunnel on transit nodes
|
This option is available if the VC3, VC11 (with XC-VXC-10G card only), or VC12 circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VC3, VC11 (with XC-VXC-10G card only), or VC12 circuits to pass through ONS 15454 SDHs without consuming low-order cross-connect card resources. Low-order tunnels are required if the circuit passes through a node with XC10G cross-connect cards. In general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the same source and destination. Refer to the ONS 15454 SDH Procedure Guide for more information.

Create VC LO aggregation point
|
This option is available if you are creating a VC3, VC11 (with XC-VXC-10G card only), or VC12 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an IOF, switch, or DACS. A low-order aggregation point (LAP) allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix.

VC4 grooming node is source node, VC LO grooming node is destination node
|
Creates the LAP on the VC11 (with XC-VXC-10G card only) or VC12 circuit source node. This option is available only if the VC11 or VC12 circuit originates on an STM-N or MRC-N card.
|
VC4 grooming node is destination node, VC LO grooming node is source node
|
Creates the LAP on the VC11 (with XC-VXC-10G card only) or VC12 circuit destination node. This option is available only if the VC11 or VC12 circuit terminates on an STM-N or MRC-N card.
|
|
Choose this option if you do not want to create a low-order tunnel or a LAP. This is the only available option if CTC cannot create a low-order tunnel or LAP.
