13.2 xTalk TDR
The
xTalk TDR
test transmits on one pair and receives
on pair two allowing you to detect and isolate split pairs
which may be causing service disruptions. The test
adds a hookup diagram in the form of a
Confirmation
window at start up, showing you how to connect your
cables for this test.
When FED is
Enabled
on the
FED Setup
page, both
the T-R/A-B and T1-R1/A1-B1 pairs will be terminated
at the FED. The hookup diagram uses graphic and
textual components.
Proceed
button closes the hookup diagram
prompt and starts the test.
Cancel
button closes the hookup diagram
prompt only.
The
Continuous
function displays the line trace and is
continuously on and ready to use. It displays and
updates results in real time, in either
Portrait
or
Landscape Mode
, until you stop the test. The last valid
results then remain displayed.

measured.
