VT Matrix Optimization
(ONS 15454 only) Use the VT Matrix Optimization page to provision the VT circuit options. The following table describes the VT Matrix Optimization page fields and buttons.

Description
Create VT tunnel on transit nodes
This option is available if a DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels enable VT circuits to pass through ONS nodes without consuming cross-connect card resources. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. For more information, refer to the applicable ONS product procedure guide.
Create VT aggregation point
The VAP option is available if the DS-1 circuit source or destination is on an OC-N, EC1, and DS3 port. The ONS 15454 also supports DS3E, DS3i-N-12, DS3XM-6, or DS3XM-12 ports. VAPs aggregate DS-1s on to an STS to hand off to the non ONS 15454 networks or equipment, such as an IOF, switch, or DACS. The VAP enables VT circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix.
STS grooming node is source node, VT grooming node is destination node
Creates the VAP on the DS-1 circuit source node. This option is available if the DS-1 circuit source is on an OC-N, EC1, or DS3 port. The ONS 15454 also supports DS3E, DS3i-N-12, DS3XM-6, and DS3XM-12 ports.
STS grooming node is destination node, VT grooming node is source node
Creates the VAP on the DS-1 circuit destination node. This option is available if the DS-1 circuit destination is on an OC-N, EC1, or DS3 port. The ONS 15454 also supports DS3E, DS3i-N-12, DS3XM-6, and DS3XM-12 ports.
None
Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.
