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
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).
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).
