Question: 
What is the purpose of the Test Protection setting on the MTS/TBERD 5800?
Answer: 
Test Protection prevents a remotely initiated test in progress from being interrupted or having its results impacted by another remote unit or port. This applies specifically to Ethernet testing where test protection is a setting that can be explicitly enabled or disabled via a user setting. Test Protection can be enabled in any Ethernet test application from the Setup>Interface>Test Control tab. Units with software earlier than release 27.1 do not support test protection, which is equivalent to having Test Protection disabled. A unit with Test Protection enabled will enter the Test Protected state (highlighted in yellow on the UI action tab in the results panel) when it is connected to another unit and a remote test is active. Active remote tests include Loop Up/Down, Enhanced RFC 2544, Y.1564 SAMComplete, RFC 6349 TrueSpeed, and QuickCheck. A remote test can be either a test running against a far-end logical loop back or unit user uni or bi-directional tests. Test Protection can be used either in workflow applications (i.e., Enhanced RFC 2544, Y.1564 SAMComplete, RFC 6349 TrueSpeed, Quick- Check) or with the regular base user interface (i.e., manual mode). Test applications must all have the same Test Protection setting in order to interoperate for remote tests. As a result, while a unit has test protection enabled, active tests can be run only against other units that also have test protection enabled. Similarly, units with test protection disabled can interoperate only against other units with test protection disabled; however, a unit setting up a test against another unit already performing a test against a third unit can impact results in an unpredictable manner
