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
directed by your ISP.
