Description
Status of the cable as a whole. The status of a cable is in
a sense, a summation of the status of its pairs. If all of the
pairs are normal, then the cable is normal.
If the cable consists of zero or more normal pairs and one or
more open pairs, then the cable is considered open. If the
cable consists of shorted pairs and normal pair, then the
cable is considered shorted. Any combination of open and
shorted pairs is considered FAILED.
Indicates status of the twisted pair. Where n is a number
that specifies the different cable pairs.
The length of twisted pair number, as measured by Time
Domain Reflectometry (TDR).
Where n is a number that specifies the different cable pairs.
This measurement can only be done if the pair is open or
shorted. Therefore, this is an "Error" length. If the pair
is good and properly terminated there is no reflection to
measure.
