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
Resistance unbalance in a pair (in limits with (+PoE) and
others)
Resistance unbalance between pairs (in limits with (+PoE) and
others)
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
TCL (transverse conversion loss, in limits with (+All))
CDNEXT (common-mode to differential-mode near-end
crosstalk, in limits with (+All))
CMRL (common-mode return loss, in limits with (+All))
ELTCTL (equal level transverse conversion transfer loss, in
limits with (+All))
HDTDR and HDTDX analyzers (optional tests, not required by
any test limit. See Chapter 6.)
