Step 9
In the Circuit Destination section of the Circuit Creation wizard, choose the destination node, slot, port,
STS, VT, or DS1 for the monitored circuit.
Note
In the
example, the monitor circuit destination is Port 2 on the EC1-12 card.

Step 11
In the Circuit Routing Preferences area, review the monitor circuit information. If you want the monitor
circuit routed on a BLSR protection channel, click

shows a sample monitor circuit setup. VT1.5 traffic is received by Port 1 of the EC1-12 card
at Node 1. To monitor the VT1.5 traffic, test equipment is plugged into Port 2 of the EC1-12 card and a
monitor circuit to Port 2 is provisioned in CTC. (Circuit monitors are one-way.) This example assumes
circuits have been created.
