- You cannot legally attach *anything* that isn't FC approved to the
- phone lines. The only way around this is to by an FCC approved
- device designed for "isolating" non-approved gear from the phone
- line. But this is apt to cost more than a cheap modem!
-
- The rules are intended to protect the phone switches and the personnel
- working on phone lines. And to protect the poor fool who thinks he
- can hook some homebrew gizmo up without knowing a *lot* about the
- phone system. (like the fact that voltages of up to 200v AC *or*
- DC may be legitimately present at times...)
