Twisted Pair Autotest Results

The tests listed below apply to twisted pair cabling.
The Autotest runs some or all of the tests listed
below, depending on the selected test limit.
•
Wire map
•
Resistance
•
Characteristic impedance
•
Length
•
Propagation delay
•
Delay skew
•
Insertion loss (attenuation)
•
NEXT (near-end crosstalk) and NEXT at the smart
remote
Note
