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 and path 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 card.
VAPs allow multiple VT1.5 circuits to pass through cross-connect cards
without utilizing resources on the cross-connect card VT matrix.

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.
Type—Choose VT Aggregation Point. The Size, Bidirectional, Number of Circuits, and Create
cross-connects fields in the dialog box become unavailable.
Size—Unavailable for VAPs.
Bidirectional—Unavailable for VAPs.
Number of circuits—Unavailable for VAPs.
Auto-ranged—Unavailable for VAPs.
State—Choose a service state to apply to the VAP:
IS—The VAP is in service.
–
– OOS—The VAP is out of service. Traffic is not passed on the circuit.
– OOS-AINS—The VAP is in service when it receives a valid signal; until then, the tunnel is out
of service.
– OOS-MT—The VAP is in a maintenance state. The maintenance state does not interrupt traffic
flow; it suppresses alarms and conditions and permits loopbacks on the VAP. Use OOS-MT for
circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or
OOS-AINS when testing is complete. See the
page 8-8.
