Suitability of junction cables for PCM transmission with measurements on selected KP & T cables
Abstract
An investigation into the suitability of paired,
voice-frequency cables for PCM transmission and the
relevant constraints involved, are given in this
report. An outline of the basic concepts of a PCM
system is given in Chapter One followed by a survey
of the principal sources of interference in the
transmission of digital signals over paired cables.
It is found that near-end and far-end crosstalk and
office noise are the only forms of interference that ..
require specific engineering measures to combat.
Supplementary factors such as line coding, cable
characteristics and construction and operation of
regenerative repeaters, that affect the development
of line engineering methods are also discussed.
