Cable at 70 F, 135Ω, resistive termination is provided in
Figure F-2.
An approximation for the maximum amount of wide-band
noise on an HDSL local loop as measured by a 50 kbps filter
is:
An approximation for the maximum level of impulse noise as
measured using a 50 kbps filter on an HDSL loop is:
Frequency (Hz)
3000
10,000
50,000
100,000
150,00
200,000
[*] These approximations are to be used as guide-
lines only and may vary slightly on different loops.
Adhering to the guidelines should produce perfor-
mance in excess of 10
