BG> Well you're wrong then, Grant.  FCC compliance for class B computing
BG> devices (modems) has absolutely NOTHING to do with electrical safety.

BG> In fact, Part 15 of the FCC regulations state that:

BG> 1.  The device may not cause harmful interference.
BG> 2.  The device must accept any interference received including
BG>     interference that may cause undesired operations.

BG> The FCC rules are specifically designed to provide
BG> reasonable protection against RFI (Radio Frequency
BG> Interference) in residential installations.

RS> Thats a different thing to FCC approval of modems tho.

BG> Nope, modems are classified as Class B computing devices in the US.

You've mangled that too. Yes, all normal electronics devices do have to
comply on that emission stuff, *BUT* thats a completely separate issue
to the FCC testing of modems on stuff like the voltage isolation test etc.

RS> What you quoted is FCC approval of say a
RS> computer, quite a separate approval process.

BG> Excuse me?

Nope, sorry, quite inexcusable |-)

BG> The above is a direct transcription from my MODEM manual, and relates
BG> directly to my USR, and presumably other US-made modems as well.

Yes, but you have confused that testing stuff on emissions, which
all normal electronics devices have to comply with, including modems
and computers, with the quite separate testing for the stuff like
modems on their effects on the phone lines and voltage isolation etc.

You can order both documents if you want to.
