3) When the measured plug NEXT loss is greater than 70 dB, the phase limit does not apply 4) When a low limit NEXT loss calculation results in a value greater than 70 dB, there shall be no low limit for NEXT loss

5) When a high limit NEXT loss calculation results in a value greater than 70 dB, the high limit NEXT loss shall revert to a limit of 70 dB

6) When the NEXT loss magnitude exceeds 70 – 20 log (f/100), the phase requirement does not apply

7) The requirements for 1-2,4-5 and 4,5-7,8 do not exclude plugs that meet cases 9 and 11, respectively, shown in table H.2, because such plugs are acceptable for field tester adapters
