____________________Reply Separator____________________ Subject: Compliance of a USB telephone Author: Ilan Cohen <ico...@itl.co.il> List-Post: emc-pstc@listserv.ieee.org Date: 11/2/00 12:48 PM 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. There is no other connection, just the USB. Clearly this unit must comply with EMC requirements. Safety requirements are not mandatory but clearly they are recommended to be performed for UL1950 for the US and EN60950 for Europe. Two questions: 1) What about Part 68 in the US? Since unit is not directly connected to the PSTN officially it is exempt from the standard. (Acoustics tests are covered under UL1950) 2) What about RTTE directive in Europe? There is no standard you can test for. All of TBR 21 tests are not applicable.
