Example
The following sets the maximum downstream power on port 1 to 14.5
dBm.
lre min-protection
This command configures the minimum level of impulse noise protection
for all bearer channels. Use the no form to restore the default setting.
Syntax
lre min-protection {down | up} value
no lre max-power {down | up}
•down – Downstream bands.
•up – Upstream bands.
•value – The number of consecutive DMT symbols for which errors
can be completely corrected. (Range:0-255, in units of 0.5 DMT
symbols, or 125 microseconds)
Default Setting
0

Interface Configuration (VDSL Port)
Command Usage
• This minimum margin indicates the amount of increase in impulse
noise that the system can tolerate under operational conditions while
still ensuring required transmission quality.
• This command is used to set the time span of impulse noise
protection, as seen at the input to the de-interleaver, for which errors
can be completely corrected by the error correcting code, regardless of
the number of errors within the errored DMT symbols.
