6.4 Creating Monitor Circuits

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 a DS-1 card. To monitor
the VT1.5 traffic, test equipment is plugged into Port 2 of the DS-1 card and a monitor circuit to Port 2
is provisioned in CTC. Circuit monitors are one-way. The monitor circuit in
monitor VT1.5 traffic received by Port 1 of the DS-1 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
