Load Coils
Load Coils
The Load Coils test allows you to detect the presence of load coils, which
are detrimental to the use of DSL technologies on the line. If a load coil is
detected, use the TDR (time domain reflectometry) test to quickly locate
and remove it from the cable.
Detection
The
Detection
function specifies the presence or
absence of load coil in the cable section, and displays
the number of load coils in the line and measured
values in graphical form.
Current Group
is the current test group name, for
example

VOP
read-only entry is the velocity of propagation for the cable
defined as m/
μ
sec (meters per microsecond), a ratio, or
percentage of the speed of light. Setup is in the
Cable Book
.
Cable Temperature
