33.3.1.4 show adsl lineqln Command
Syntax:
show adsl 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 DSL signals
are present. It is measured in dBm/Hz. The QLN can be used in analyzing crosstalk.
The following example shows the Quiet Noise Level on port 1 of the line ADSL line card in
slot 3.

DESCRIPTION
This shows the location of the line test. "near end" refers to upstream traffic, or
traffic from the CPE device. "far end" refers to downstream traffic, or traffic from
the CO device.
This shows the frequency in increments of 4.3125 KHz. Single digit units on the
top row are added to the units in tens on the left hand column to find the
corresponding value in the table. For example, to find the Hlog value for tone band
43, locate 40 in the left hand column and 3 in the top row. The intersection of the
column 3 and row 40 gives a Hlog value of 5.
