When detailed information is displayed, status for a twisted pair:
Failed —TDR test failed on the cable pair.
—Impedance on the twisted pair is not correct.
Impedance Mismatch
Possible reasons for an impedance mismatch include:
The twisted pair is not connected properly.
The twisted pair is damaged.
The connector is faulty.
—No cable fault detected for the twisted pair.
Normal
—Lack of continuity between the pins at each end of the
Open
twisted-pair.
—A short-circuit was detected on the twisted pair.
Short on Pair-n
When summary information for all interfaces is displayed, status for
the cable as a whole:
—A fault was detected on one or more of the twisted-pairs.
Fault
OK —No fault was detected on any of the twisted pairs.
Distance to the fault in whole meters. If there is no fault, this value is
0.
When summary information for all interfaces is displayed, this value
is the distance to the most distant fault if there is more than one
twisted pair with a fault.
