RE: RTTE or LVD for Equipment with E1 SELV interfaceJoe,
If there is no physical connection to the PSTN, the R&TTE directive is not
applicable. CE Marking will cover all the necessary Safety and EMC
requirements for the EU. Hope this helps.

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.
Thx,
Joe

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...
Richard Hughes

Peter,
As this product does not connect to the PSTN and is destined for
the
Central Office only, I would say the R&TTE Directive does not apply as the
scope does not include Network Equipment.
Thx,
Joe

Dear All,
For an equipment where the E1 has been assessed for SELV under EN
60
950 (ie for intrabuilding use and not subject to overvoltages), does the
equipment fall under the RTTE Directive or can the manufacturer declare
compliance to the LVD and EMC Directives.
If under the RTTE Directive, what telecom standard applies to the
E1
intrabuilding interface?
