Level 1 vs. Level 2 accuracy

Q: How do we know if our current cable test equipment is Level 1 or Level 2? If it is indeed Level 1, will the manufacturers retrofit our current testers, or will we end up with a $4000 paperweight?

A: When the ink is finally dry on TSB-67, link performance transmission specifications for field testing of unshielded twisted-pair cabling systems, none of the analog testers currently in production will meet Level 2, and some may not meet Level 1.

Contact the manufacturer of your tester and request a list of the upgrade options being offered. The tester manufacturers I spoke with each indicated that they will have an upgrade plan, but details were sketchy.
