Tone Settings
The frequency band of ADSL is split up into 256 separate tones,
each spaced 4.3125 kHz apart. With each tone carrying separate
data, the technique operates as if 256 separate modems were
running in parallel. The tone range is from 0 to 31 for upstream
and from 32 to 255 for downstream. Do not change these settings
unless so directed by your ISP.
