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.
