Interpreting Cable Test Results
The Pass icon will be on if the cable has
all pins properly connected per T568A/B
for network cables or per -pair USOC for
telephone cables. The Fail, Short, Open or
Split icon will be on if there is a wiring error.
The wire map will display the end-to-end
connections measured whenever possible.
The Pass icon will also be on with a flashing
Uplink icon if a network cable has the -
and the -6 pairs transposed to indicate a
properly wired uplink (crossover) cable. In
Telephone mode, the Rev icon will flash if all
connected pins are in reverse order and the
Pass icon will also be on if all 6 connections
are present. Telephone modular plug cables
used between the wall jack and a phone set

The severity has to do with the ability of
a more severe error to mask less severe

cable, miswires and split pairs may not be
detected for the pairs involved in the short
fault.
Short - The pair has a low resistance
