Description
Contact your Scientific Atlanta.
If the QAM Encoding Type parameter is missing from the
configuration file then this alarm is raised. A Scientific Atlanta
representative should be contacted.
Description
There is a frequency range in which the Continuum DVP Dense QAM
Array 24 device works. This alarm is raised and the RF Output of the
QAM card in question is switched off if the frequency is outside of
that range. The frequency should be set to be inside the support range.
<X> represents the QAM card number and <Y> the RF output
number.
The output level has been set out of range. The output level is set to
the minimum or maximum value. Set the output level between 45.0
and 55.0 to clear this alarm.
<X> represents the QAM card number.
The symbol rate has been set out of range. During this alarm the RF
output of the QAM card in question is switched off. Set the symbol
rate between 5.0 and 5.5 (ITU-B and ITU-C) or 5.0 and 7.0 (ITU-A) to
clear this alarm.
<X> represents the QAM card number.
The channel spacing has been set out of range. Set the channel spacing
to 6 (ITU-B and ITU-C) or 7 or 8 (ITU-A) to clear this alarm.
<X> represents the QAM card number and <Y> the RF output
number.
This is a warning to show that the bandwidth exceeds the channel
spacing. Decrease the symbol rate to clear this alarm.
<X> represents the QAM card number.
