DSX-PCxx Patch Cord Adapters
Users Manual
6 Mark the reference patch cord ends with "main" and "remote" as it was
connected for the test. Keep the reference patch cord to use later for
performance tests on the adapters.
For consistent return loss measurements from the reference
patch cord, do not put mechanical stress on the cord during
tests or storage. Patch cord performance can change when
you bend or twist the cord.
When you do a test on the reference patch cord later, you
will use the same main and remote DSX testers you used for
the initial test. The test results include the serial numbers of
the testers.
How to Verify the Adapters' Performance
Use this procedure to compare results from the initial characterization test with
current results to see if the adapters are operating correctly.
1 Use LinkWare to open the results from the initial test on the reference patch
cord.
2 Get the same main and remote DSX testers you used for the initial test.The
serial numbers are in the test results.
3 Attach the patch cord adapters to the testers.
4 Connect the reference patch cord between the main and remote DSX testers.
Make sure to connect the ends of the patch cord to the correct testers.
5 On the DSX tester, select the same patch cord test limit you used for the initial
test.
6 Do an Autotest, then save the results.
7 Use the plots on the DSX and in LinkWare to compare the NEXT and RL
margins in the areas nearest the limit line. For a good adapter and jack, the
old and new NEXT and RL margins should be very similar.
