EN 41003 deals specifically with the safety of telecom equipment, and is similar to UL 1459. Both these standards came into existance because hazardous voltage is consider anything over 42.4 volts, and generally, the ring voltage on the PSTN is 48 volts. Telecom and basic telephony was different enough from other equipment to warrant a separate standard, rather than lump it in with general hazardous voltage safety. Currently though, EN 41003 is included in EN 60950 as Clause 6 just as I believe UL 1459 is included in UL 1950. roger [email protected] "The earth, that's nature's mother, is her tomb; What is her burying grave, that is her womb:" - Friar Lawrence, 'Romeo and Juliet', William Shakespeare
