Step 6 If you connected the transmitter to Port 10, connect the client or test set receiver to Port 5 on the Y-cable
module. If not, connect the client or test set receiver to Port 11 of the Y-cable module.
At the far-end site for the circuit under test, physically loop the Y-cable module as follows:

This procedure tests the optical path, client transponders, and Y-cable
protection groups in your system for proper operation. The test signals can be
generated by either the actual client device or a test set, whichever is available.
Cisco recommends that you repeat this test at each node in the network where
protection group traffic is dropped.
A list of protection groups. This information is provided in the
Cisco MetroPlanner Traffic Matrix.
A test set or actual client device that provides the required payload for the
circuits that are provisioned.
As needed
Onsite; personnel are required to be on site at each end of the circuit under
test.

In node view, click the Provisioning > Protection tabs.
In the Protect and Working areas, confirm the correct transponders are in the Y-cable protection
group by viewing the slot number and card type.
If the required protection group is not provisioned, stop and perform

If this is the first client on the Y-cable module, loop Port 10 to Port 5 on the far-end Y-cable module.
If this is the second client on the Y-cable module, loop Ports 11 and 12 on the far-end Y-cable
module.
