Note VT aggregation points can be created for circuits on BLSR, 1+1, or unprotected nodes. They cannot be
created for circuits on path protection nodes.
The maximum number of VAPs that you can create depends on the node protection topology and number

of VT1.5 circuits that terminate on the node. Assuming no other VT1.5 circuits terminate at the node,
the maximum number of VAPs that you can terminate at one node is 8 for 1+1 protection and 12 for
BLSR protection.

This procedure creates a VT aggregation point (VAP). VAPs allow multiple
DS-1 (VT1.5) circuits to be aggregated on a single STS on an OC-N, EC1,
DS3, DS3E, DS3i-N-12, DS3XM-6, or DS3XM-12 card. VAPs allow
multiple VT1.5 circuits to pass through cross-connect cards without
utilizing resources on the cross-connect card VT matrix. You also have the
option to route the circuit through a portless transmultiplexing interface.
For portless transmultiplexing configurations, a DS3XM-12 card must be
installed on a node in the network.

Name—Assign a name to the VT aggregation point. 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 VAP.
