12. AUTO NOISE LEVEL FUNCTIONALITY
Auto Noise Level Adjustment is a very useful feature in HomePNA Switch
when installing under noisy line conditions, or with old wiring. The unit can
automatically compensate for noise within the line by analyzing the signal of
each port and adjust its noise floor accordingly.
You can turn on/off the Auto Noise Level feature through the ICD
command interface via Console or Telnet. The commands to activate and
deactivate this feature within the ICD command interface are “AO” and “AF”
respectively.
You can also turn on/off Auto Noise Level to individual port using ICD
commands. Please contact your vendor for more information on turning
on/off to individual port.
Occasionally you will find that the Auto Noise Level feature unable to
compensate for the noise in certain lines. This is uncommon, usually caused
by noisy lines and surroundings or bad wiring (high impedance). Signs of
trouble with the noise floor would be indicated by excessive collisions on the
affected port, or loss of link status with a sudden gain in status.
If you believe your switch needs adjustment, please contact your vendor.
