Twisted Pair Autotest Results
The tests listed below apply to twisted pair cabling.
Note
Some tests are not included in some test limits.
 Wire map
 Resistance
 Length
 Propagation delay
 Delay skew
 Insertion loss (attenuation)
 Impedance
 NEXT (near-end crosstalk)
 PS NEXT (power-sum near-end crosstalk)
 ACR-N (attenuation to crosstalk ratio at the near end)
 PS ACR-N (power-sum attenuation to crosstalk ratio, near
end)
 ACR-F (attenuation to crosstalk ratio at the far end)
 PS ACR-F (power-sum attenuation to crosstalk ratio, far end)
 Return loss
 HDTDR and HDTDX analyzers (optional tests, not required by
any test limit)
