HDSL 3192 HTU-C Installation and Maintenance Practice
Cable Gauge
Recommended maximum local loop loss information for PIC cable at 70°F, 135 Ω, resistive
termination is provided in
An approximation for the maximum amount of wideband noise on an HDSL local loop as
measured by a 50 kbps filter is ≤ 31 dBrn.
An approximation for the maximum level of impulse noise as measured using a 50 kbps filter
on an HDSL loop is ≤ 50 dBrn.
These approximations are to be used as guidelines only and may
vary slightly on different loops. Adhering to the guidelines should
produce performance in excess of 10
