33.3.35 show vdsl linehlog Command

Syntax:
show vdsl linehlog <slot-port>
This command displays the loop response using a logarithmic scale. These values can then be
used to estimate line characteristics such as line make-up and length.
The following example shows hlog values on the VDSL line connected to port 22 on the line
card inserted in slot 2.

Syntax:
show vdsl lineqln <slot-port>
This command displays the Quiet Line Noise level on a line. This is the rms (root mean
square) level of the noise present on the line for a DMT tone when no ADSL or VDSL signals
are present. It is measured in dBm/Hz. The QLN can be used in analyzing crosstalk.
