You can set up secondary circuits to monitor traffic on primary bidirectional circuits.
an example of a monitor circuit. At Node 1, a VT1.5 is dropped from Port 1 of an EC1-12 card. 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. The monitor circuit in
to monitor VT1.5 traffic received by Port 1 of the EC1-12 card.
Monitor circuits cannot be used with EtherSwitch circuits.
Note
For unidirectional circuits, create a drop to the port where the test equipment is attached.

Procedure: Create a Monitor Circuit

Log into CTC.
Step 1
In node view, select the Circuits tab.
Step 2
Select the bidirectional circuit that you want to monitor. Click Edit.
Step 3
On the Edit Circuit dialog box, click the Monitors tab.
Step 4
The Monitors tab displays ports that you can use to monitor the circuit selected in Step 3.
Step 5
On the Monitors tab, select a port. The monitor circuit displays traffic coming into the node at the
Step 6
card/port you select. In
entering Node 2 on the DS1-14) or the OC-N card at Node 1 (to test circuit traffic entering Node 1 on
the OC-N card).
Step 7 Click Create Monitor Circuit.
On the Circuit Creation dialog box, select the destination node, slot, port, and STS for the monitored

circuit. In the
Step 9 On the Circuit Creation dialog box confirmation, review the monitor circuit information. Click Finish.
Step 10 On the Edit Circuit dialog box, click Close. The new monitor circuit displays on the Circuits tab.
