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
Protection Group” procedure on page 5-10
. Otherwise continue with
.
Step 4
Repeat
for each Y-cable protection group at this node. When all protection groups are verified,
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
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 (
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
