David, I am quite certain that a 'telecommunications center' is a central office. But, before just assuming that Class A is ok for telecom centers, I'd check with the telecom company to be sure that they don't have a requirement for Class B (I have this gut feel that I've run into that but I can't remember any specifics). Best Regards -Dave

EMC radio equipment standard EN 301 489-1 calls out EN 55022 Class B limits in general, and Class A limits for "...equipment intended for use in telecommunication centres only,..." What is considered a "telecommunication centre?" Unfortunately I can not find any definition for this term in the standard, or in any other standards I have consulted. Is a point-of-sale terminal system with a rooftop antenna considered a "telecommunication centre?" My understanding is that EN 55022 Class B limits apply to residential environments, and Class A applies to commercial and industrial environments. I would hope in our situation that Class A will suffice. If not I am up the proverbial creek without a paddle... Thanks in advance, David. David Gelfand, P.E.
