NTP-G142 Perform a Protection Switch Test
Step 1 Complete the “DLP-G46 Log into CTC” task on page 2-25 at an ONS 15454 on the network.
Step 2 Identify the Y-cable circuit to be tested by viewing the Traffic Matrix for your site. Locate the
transponders in the ONS 15454 node that will be used for the protection group.
Step 3 Verify that the Y-cable protection group is provisioned:
a. In node view, click the Provisioning > Protection tabs.
b. 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.
c. If the required protection group is not provisioned, stop and perform “NTP-G33 Create a Y-Cable
Protection Group” procedure on page 5-10. Otherwise continue with Step 4.
Step 4 Repeat Step 3 for each Y-cable protection group at this node. When all protection groups are verified,
proceed to Step 5.
Step 5 Physically connect the transmitter of the client or test set to either Port 10 or Port 12 of the Y-cable
module protecting the circuit under test. (See Table 3-4 on page 3-79 and Table 3-5 on page 3-80.)
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.
Step 7 At the far-end site for the circuit under test, physically loop the Y-cable module as follows:
a. If this is the first client on the Y-cable module, loop Port 10 to Port 5 on the far-end Y-cable module.
b. If this is the second client on the Y-cable module, loop Ports 11 and 12 on the far-end Y-cable
module.
Step 8 At the near-end site for the circuit under test, place the client device or test set into service and begin
transmitting the required payload.
Step 9 In CTC, display the near-end site in node view.
Step 10 Click the Maintenance > Protection tabs (Figure 6-1).
Purpose 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.
Tools/Equipment 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.
Prerequisite Procedures None
Required/As Needed As needed
Onsite/Remote Onsite; personnel are required to be on site at each end of the circuit under
test.
Security Level Provisioning or higher
