Step 10
In the Circuit Destination area, choose the node where the VT circuits aggregated by the VAP will

terminate from the Node drop-down list.
Click Next.
Step 12
In the Circuit Routing Preferences area, choose Route Automatically. Complete the following, as
Step 13
necessary:
Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or
•
exclude in the CTC-generated tunnel route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path
of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans
are not in the working or protect path of the circuit.
Review Route Before Creation—Check this check box to review and edit the VT tunnel route before
•
the circuit is created.
VT-DS3 Mapped Conversion—Check this check box to route the VT tunnel over a portless
•
transmultiplexing interface. This check box will be unavailable if you chose a DS3, DS3E,
DS3i-N-12, DS3XM-6, or DS3XM-12 card as the VAP source in

Click Next.
a.
In the Circuit Route Constraints area, click a span on the VAP map.
b.
c. Click Include to include the node or span in the VAP. Click Exclude to exclude the node or span
from the VAP. The sequence in which you choose the nodes and spans sets the VAP sequence. Click
spans twice to change the circuit direction.
Repeat Steps b and c for each node or span you wish to include or exclude.
d.
Review the VAP route. To change the tunnel routing order, choose a node in the Required
e.
Nodes/Lines or Excluded Nodes Links lists, then click the Up or Down buttons to change the tunnel
routing order. Click Remove to remove a node or span.

a.
b. Review the tunnel route. To add or delete a tunnel span, choose a node on the tunnel route. Blue
arrows show the tunnel route. Green arrows indicate spans that you can add. Click a span arrowhead,
then click Include to include the span or Remove to remove the span.
If the provisioned tunnel does not reflect the routing and configuration you want, click Back to
c.
verify and change tunnel information.
Click Finish. The Circuits window appears.

Step 15:
Node—Choose a node with a DS3XM-12 card installed.
Slot—Choose the slot where a DS3XM-12 card is installed.
DS3 Mapped STS—If applicable, choose Circuit Dest to indicate that the STS is the circuit
destination, or Circuit Source to indicate that the STS is the circuit source.
