Richard, Good point - the "directly or indirectly" part grabbed my attention but that seems too broad a description which could encompass quite a wide range of equipment. However, the point of discussion here is whether a product classified as SELV by IEC 60950, Type 2 by GR-1089, etc. and does not connect (interface) to the "Public" telecommunications network is included in the scope of the R&TTE Directive. This type of product resides in the network and does not connect to outside plant conductors - terminates to another piece of equipment with the proper isolation to outside plant conductors. My interpretation is that if there is no provision for physical connection to the PSTN, the R&TTE does not apply. Any takers??? I'll copy the TREG and NEBS gurus on this one as well.

Joe, The R&TTED applies to the following types of equipment: 1) Radio equipment 2) Terminal equipment. The Directive also contains the following definitions: '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). 'interface' means (i) a network termination point, which is a physical connection point at which a user is provided with access to public telecommunications network, and/or (ii) an air interface specifying the radio path between radio equipment and their technical specifications It will be seen from the above that the R&TTED is not limited to PSTN since it is quite possible that a network operator could provide a business with an E1 interface, for instance. Peter, It is for the manufacturer to decide to which market, e.g. terminal equipment or central office equipment only, they whish to sell their product into. EN 60950 has nothing to do with it since this standard can be used to evaluate either type of product - and other non-telecom ICT products as well of course. Simplistically, if the product does not have an input or output voltage in the range 50-1000Vac, 75-1500Vdc then the LVD does not apply {ref. Article 1 of LVD}. Clearly, if the LVD does apply then certain editions of EN 60950 do provide a presumption of conformity with the safety objectives of the LVD. If the LVD does not apply then that should not be taken as an excuse to not comply with EN 60950, but that's another debate entirely. If the R&TTED applies then the EMC is not applied as such, because the EMC requirements are then covered by the R&TTED. However, this is largely an administrative technicality because Article 3(1)(b) points to the EMC Directive for its essential requirements, just as Article 3(1)(a) points to the LVD for safety (minus any upper or lower voltage limit). Well, that's enough personal opinions expressed on this matter for me...

If under the RTTE Directive, what telecom standard applies to the E1 intrabuilding interface? This e-mail message may contain privileged or confidential information.
