VC Matrix Optimization


Use the VC Matrix Optimization page to provision the virtual container (VC) circuit options. The following table describes the VC Matrix Optimization page fields and buttons.

Description

Create VC LO tunnel on transit nodes

This option is available if the VC3 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 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 or VC12 circuit to an STM-N port for handoff to non-ONS 15454 SDH networks or equipment, such as an inter-office facility (IOF), switch, or digital access cross-connect system (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], VC12 grooming node is [destination node]

Creates the LAP on the VC12 circuit source node. This option is available only if the VC12 circuit originates on an STM-N card.

VC4 grooming node is [destination node], VC12 grooming node is [source node]

Creates the LAP on the VC12 circuit destination node. This option is available only if the VC12 circuit terminates on an STM-N card.

None

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.
