Sorry for my late reply. For applying the R&TTE directive, the intended use is the crux. I wander or it is possible nowadays - if computers are connected to the internet- , to deny that it is not intended for communication using the internet; for example using Voice over IP! I would say that every computer (and connected equipment), that can communicate to the internet is falling under the scope of the R&TTE. Consider for yourself what is stated in the R&TTE directive: "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); Only when it is IMPOSSIBLE to reach a public network, the R&TTE is not applicable. The consequence for the USB telephone is that there are no restrictions on the power voltage (as stated in the LVD), so the telephone must fully comply with all the requirements as mentioned in the safety directive(for example acoustical shock) Best regards, Theo Hildering KTL -----Original Message----- From: owner-emc-p...@ieee.org <mailto:owner-emc-p...@ieee.org> [mailto:owner-emc-p...@ieee.org] <mailto:[mailto:owner-emc-p...@ieee.org]> On Behalf Of wo...@sensormatic.com <mailto:wo...@sensormatic.com> Sent: 02 November 2000 19:29 To: ico...@itl.co.il; <mailto:ico...@itl.co.il;> emc-p...@ieee.org <mailto:emc-p...@ieee.org> Subject: RE: Compliance of a USB telephone Let me see if I understand this product. It is a telephone like device that is solely intended to be connected to the USB port of a PC and it is not intended to be connected to the telephone network. If this is true, then no telephone standards, regulations or directives apply. Only the EMC directive applies in the EU. The RTTE directive does not apply since the device is not intended to be connected to the telephone network. The LVD does not apply since the source voltage is too low. Compliance with safety requirements of EN60950 is sufficient to show due diligence for the Liability Directive and General Product Safety Directive. > Dear Group > > We are testing an PC telephone unit! > > It is a telephone terminal unit that connects to the USB port of the PC from > which it receives power.
