SPLIT PAIRS:
If a cable is wired correctly, pin-to-pin, but there is a split pair,
Wiremap displays Split Pairs and highlights the pins in error.
In our example, one wire from the 4-5 pair is
twisted with one wire in the 7-8 pair. The Split
Pair will be highlighted with reversed numbers.
The message SPLIT PAIRS will be displayed below
the Wiremap.
Press ESC to exit the WIREMAP screen.
TDNXT
NEXT faults are diagnosed by using the TDNXT (Time Domain NEXT)
function. OMNIS
CANNER
uses TDNXT to determine the amount of NEXT
as a function of distance. TDNXT with new S-Band™ technology
(Standard Connector Band technology) can help you distinguish
between connection and cable faults. It assists you with diagnosis and
troubleshooting of NEXT failures and the verification of test cables,
connectors and plugs.
While the NEXT graph shows the link test limits and the frequency at
which a failure occurred, the TDNXT graph displays NEXT vs. distance.
S-Bands™ provide a time domain limit to verify that the connections
are within the desired category of performance. In a typical link,
failures are a result of either a non-compliant connection or a faulty
cable. The ability to determine if a connection meets the expected
performance requirement significantly simplifies the diagnosis of a
failure.
To diagnose a failure, select TDNXT in the DIAG-
NOSTICS screen and press ENTER. The TDNXT
function is also available from the NEXT Graph
screen.
The SELECT PAIRS screen opens.
Use the (Pair) function key to select the
pairs you want to analyze.
