It seems -- in our haste to include USB handsets under the Directive -- we
have ignored computer microphones. Yet the microphone -- if the handset is
subject -- SHOULD be subject to it. It is no less likely to be used for
communications than a handset connected to the computer, once we are doing
Voice over Internet. But the computer microphones are NOT evaluated under
the R&TTE Directive, even when used for VoIp.
The logical conclusion from this is, that the interposition of the computer
and its modem between the public switched network and the audio device is
enough to remove it from consideration as a terminal device. At least, that
seems to be the practice! Anyone here up to getting R&TTE certification for
EU 0.5 microphones? What about amplified speakers used to receive the
telephone conversation? The sound card? A USB mouse?
A fiction: I once listened to a recorded radio play, with a telephone call
in it. A wizened, malevolent elf sprang out from behind a curtain,
confiscated my non-R&TTE-compliant tape player (it had played a dial-tone!)
and disappeared. Not indirect enough! Poof!
Cheers, all!

Dear all,
The R&TTE is meant for terminals. If my message was not clear enough I
repeat here once again the R&TTE scope (see below). I disagree with Gary
regarding his statement that an USB telephone, computers and other
indirectly connected stuff are not falling under the R&TTE scope
(connected directly or indirectly by any means whatsoever whatsoever to
interfaces of public telecommunications networks).
Just read for yourselves what is stated in the R&TTE and conclude for
yourselves.
>"telecommunications terminal equipment" means a product enabling
>communication or a relevant component thereof which is intended to be
>connected directly or indirectly by any means whatsoever to interfaces of
>public telecommunications networks (that is to say, telecommunications
>networks used wholly or partly for the provision of publicly available
>telecommunications services);
Perhaps you were confused by the former TTE directive. Indirectly
connected
equipment was excluded under that directive, but that's history now.
Best regards
