Interpreting Cable Test Results

The PASS icon will be on if the cable has all

pins properly connected per T568A/B. The

FAIL icon will be on if there is a short or split

pair. Neither icon will be on if there are opens

or miswires. The wiremap should be inspected

for these types of errors.

Definition of Errors – (See failure example

drawings) The three classes of faults discussed

below are in order of severity. The severity has

to do with the ability of a more severe error

to mask lower severity errors. For example,

if there is a short in the cable; miswires and

split pairs may not be detected for the pairs

involved in the short fault.

Short – The pair has a low resistance

connection from one wire of the pair to the

other wire of the pair, or to any other wire in

the cable or the shield. A short in the TEST

mode is indicated by the FAIL icon being on

and flashing X’s in the appropriate pin position

of the second line of pin numbers, plus one or

more error message lines listing all the pins

shorted together. In the PRE-TEST mode, the

error messages are displayed.
