I wasn't able to see the formatted original message, but by looking over shoulders in others' replies I could read it. Another advantage of Classic Compuserve; I can only get ASCII text. Of course this eliminates most viruses. (grin)
The Telcordia document called Network Equipment Building Standards is SR-3580. This lists what requirements are associated with each level of NEBS compliance. These requirements are found in GR-63, GR-78 and GR-1089. However, SR-3580, in setting different levels of compliance, seems to allow omitting some NEBS requirements, and that, customers might not accept. For example, some RBOC's may not only refuse to accept this approach, but also supplement existing requirements with ones of their own. They do this because they've found NEBS compliance to be a _minimum_ requirement. Yes, NEBS testing is exhaustive. It is expensive. You will destroy equipment doing it, both as part of the testing (burn testing, second level lightning and power-cross) and when it fails (ejected cards and bent card cages from shaking, charred backplanes, etc). But this is merely the cost of doing business. And not every lab does it, so you must deal with those who do. Likewise, if you are thinking of setting up a lab, don't think it merely mirrors IEC and FCC tests. Far from it! So, you need to contact Telcordia and buy copies of the standards involved. If you are making telecomm equipment, NEBS is not the only hoop you will jump. But if you are looking at NEBS, you can START with SR-3580. That will let you know what to buy _next_. (IMO, GR-1089) And it doesn't end there! I am no longer in a position to answer specific questions about NEBS. But if you are serious about business, the cost of buying the standards is WELL justified.
