Some information on BPL from Wednesday's Federal Register:

The United Telecom Council (UTC) will maintain a public
database on USA Access BPL systems effective 19 November 2005.
That is persuant to FCC Regulations Part 15.615 (a) through (e).

The database access is open, requires no log-in information.

Exactly what will be IN that database was not made clear in
the Federal Register. For history on that, see ET Docket
numbers 04-37 and 03-104. There are 35 companies in the UTC.
