DESCRIPTION

log(dB)

This is a format for providing channel characteristics. It provides magnitude

 

values in a logarithmic scale. This can be used in analyzing the physical

 

condition of the DSL line.

 

 

QLN(dBm)

The Quiet Line Noise for a DMT sub-carrier is the rms (root mean square) level

 

of the noise present on the line, when no DSL signals are present. It is

 

measured in dBm/Hz. The QLN can be used in analyzing crosstalk.

 

 

SNR(dB)

This is the upstream and downstream Signal-to-Noise Ratio (in dB). A DMT

 

sub-carrier’s SNR is the ratio between the received signal power and the

 

received noise power. The SNR can be used in analyzing time dependent

 

changes in crosstalk levels and line attenuation (such as those caused by

 

temperature variations and moisture).

 

 

52.3 Alarm Profile Commands

Configure alarm profiles to set alarm settings and thresholds for the DSL ports.

52.3.1 Alarm Profile Show Command

Syntax:

ras> adsl alarmprofile show [profile]

where

[profile]

= The name of an alarm profile.

Displays the settings of the specified alarm profile (or all of them if you do not specify one). The following example displays the default alarm profile (DEFVAL).
