CHAPTER 5: Interpreting Cable Test Results

5. 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 3-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 (see Figure 5-1) will also be
on with a flashing UPLINK icon if a
network cable has the 1–2 and 3–6 pairs
transposed. This indicates a properly wired
uplink (crossover) cable. In telephone
mode, the REV icon will flash if all
connected pins are in reverse order.
The PASS icon will also be on if all 6
