For a DTX-PCxxS/SR remote adapter with a Category 5e jack, the value should be
better than 53 dB.

be better than 62.5 dB at 100 MHz.
The 10 dB difference between the main and remote

How to Test the Performance of the Adapters Later
To test the same adapters later, repeat the characterization tests above for the main
and remote adapters using the same DTX-AXTERM plug and DTX CableAnalyzer main
unit. If the old and new results are more than 0.5 dB apart at 100 MHz, the RJ45 jacks
may need replacing. See "Replacing the Adapter's Jacks" on page 8 for details.
