MSC1000G/1024G/1224G Series User's Guide
DESCRIPTION
Select a type of line information to display
linedata: Displays an ADSL port's line bit allocation.
linegain: Displays the line gain of the active ADSL line. Line gain represents
the signal input required to compensate for losses in signal strength at
different frequencies.
linehlog: This command displays the loop response using a logarithmic scale.
These values can then be used to estimate line characteristics such as the line
make-up and length.
lineqln: 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.
linetssi: Displays the TSSI (Transmitter Spectrum Shape Index) of
transmission on the specified DSL line. This tests the variation of the actual
PSD (Power Spectrum Density) from the specified PSD.
Select Near to display results for the upstream traffic (coming from the
subscriber to the line card).
Select Far to display results for the downstream traffic (going from the line
card to the subscriber).
Click this to display the line information as a line graph.
