•Tone – Disables downstream or upstream VDSL signals at frequencies
less than or equal to 640KHz, 1.1 MHz or 2.2 MH z. (Default: Disable
tones at 640 KHz and below)
This parameter specifies a frequency beneath which VDSL signals are
not allowed. For example, the default lower frequency bound for DS1
defined in Annex C of G.993.2 is 640 KHz. The low-end frequencies
filtered out by this parameter are used for common POTS or ISDN
services.
The frequency bound specified by this parameter takes precedence over
that defined in the selected band plan.
•Data Rate – Specifies the minimum and maximum data rate for
downstream and upstream fast or slow (interleaved) channels.
(Default:64 kb ps minimum, 200,000 kbps maximum)
The parameter sets the minimum and maximum data rates supported by
each upstream and downstream band. Bounding data rates should be set
for both fast and slow channels if operation may sometimes disable or
enable interleaving. These bounds are applied to the specified interface
when rate adaption is enabled.
•Max Power – Sets the maximum aggregate downstream or upstream
power. (Range: 0-255, in units of 0.25 dBm; Default:255,which is
equivalent to 63.75 dBm)
•Min Protection – Configures the minimum level of impulse noise
protection for all bearer channels. This is expressed in 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: 0)
