b. Definitions. The circuit conditioner must use terms specific to his
task. For convenience these terms are grouped into applications before and
after equalization.
In all applications, absolute delay is the measured
time delay indicated by the DELAY meter on the TS-2669/GCM. When the end-
to-end with reference return is used, total delay is the sum of delay in the
line under test plus auxiliary line delay.
In this method the auxiliary
line delay is the delay in the line used to return the reference signal to
the transmitting test set.
The calculated delay of the line is the
difference between the total delay and auxiliary line delay.
(1) Before equalization.
(a) Initial line delay is the absolute (measured) delay in the
line under test.
(b) Average delay is the average of maximum and minimum initial
line delays; that is, the sum of the two delays divided by 2.
(c) Primary delay is the difference between maximum and minimum
initial line delays.
