Types and features of subscriber lines
(category class and thickness)
Features of subscriber lines determine the amount of signal loss and
interference between subscriber lines. CAT3/4/5 twisted pair cable is
generally recommended for lossless data communication.
However, untwisted cable(e.g., TIV and SH cable) which may result
excessive interference are not recommended. Also bridged tabs especially
with open end point may result severe signal loss.
