<portlist> =
You can specify a single ADSL port <1>, all ADSL ports <*> or
a list of ADSL ports <1,3,5>. You can also include a range of
ports <1,5,6~10>.
<l0time> =
Set the minimum time in seconds (120~65535) that the ADSL
line must stay in L0 power mode before changing to the L2
power mode.
<l2time> =
Set minimum time in seconds (60~65535) that the ADSL line
must stay in the L2 power mode before reducing the power
again in the L2 power mode.
<l2atpr> =
Set the maximum Aggregate Transmit Power Reduction (ATPR)
in decibels (dB) that is permitted in a L2 power reduction. The
system can gradually decrease the ADSL line transmission
power while it is in the L2 power mode. This is the largest
individual power reduction allowed in the L2 power mode. The
range is 1~5(dB).
<l2atprt> =
Set the maximum Aggregate Transmit Power Reduction Total
(ATPRT) in decibels (dB) that is permitted in the L2 power
mode. This is the total transmit power decrease that is allowed
to occur in the L2 power mode. The range is 1~40(dB).
