Theo I thought I should post the consensus of our discussion on the applicability of the R&TTE Directive for the avoidance of doubt by other readers of this newsgroup.
The R&TTE applies to TERMINAL equipment - that is equipment connected on the subscribers side of the NTTP (Network Test and Terminal Point). Therefore a modem in a users home is covered by the R&TTE as would a modem used by a company that does not have a telecommunications operators licence. It does not apply to NETWORK equipment - that is equipment on the network side of the NTTP which is owned by the PTO (licensed Public Telecommunications Operator). Therefore an ISP's (Internet Service Provider's) modem, typically rack mounted and sited in the local exchange, is Network equipment and is not within the scope of the R&TTE. This difference may seem academic as there are no Telecommunications Terminal Equipment specifications designated under the R&TTE Directive and safety to EN 60 950 applies on both sides of the NTTP but the EMC specifications are slightly different. EN 300 386-2 "Electromagnetic compatibility and Radio spectrum Matters (ERM); Telecommunication network equipment; Electro-Magnetic Compatibility (EMC) requirements; Part 2: Product family standard" applies to Network equipment but not to Terminal equipment. Hope this helps Allan __________________ In article <EDFA411E5E4AD2118D6F00A0C99E4BAC01DF752E@FLBOCEXU02>, wo...@sensormatic.com writes > >Forwarding a reply > >---------- >From: H.T.
