Well, first, you'll have to point me exactly where in Part 15 telephone equipment is exempted. It's debatable that the telephone 'company' is exempt from OSHA since public mains power comes into the COs for other types of equipment, to include some telephonic equipment that uses 120vac. I was specifically referring to only tleco equipment that used the 48vdc rails. On the emc side, yes, there is a wider range of testing *available* (important word here). That does not in any way mean that *all* of GR-1089 or 63 are to be used. These standards are customer driven and to the letter of the Bellcore standards, they may (and believe me they do) modify them at their discretion. A classic example is claiming a product to be NEBS compliant. The equipment would have to go through ALL testing in '63 to be NEBS compliant. At a previous company I routinely advised marketing to be very careful how the contracts were written. Bellcore specifically states a disclaimer in the beginning of all their standards. I also told them to advise the customers that unless specifically told otherswise, emissions testing and safety testing were to follow ONLY FCC part 15 for emissions, and UL-1950 for safety with Part 68 assumed would over-ride 1089. The only thing the customers wanted beyond that was shake, flame spread, needle flame, and temp/humidity from '63 and ESD from '1089. ************************************************************ ------------------------------------------------------------ The comments and opinions stated herein are mine alone, and do not reflect those of my employer. ------------------------------------------------------------ ************************************************************
