The mistake is assuming there is only one "Book." Even telephone companies make this mistake. There Book isn't always the best way to do some things. There is/was the Book according to Ma Bell (now telcordia). There is/was the Book according to IBM. There is/was the Book according to DoD. There is/was the Book according to USDA (yes, the US Department of Agriculture has a book on how to build a Central Office). There are the (many, many) Books according to ITU/ISO/ANSI/T1. The interesting thing is none of them completely agree with any of the others. You need a good understanding of the assumptions which went into the book. If you plan to put data processing equipment into a facility, Bellcore/Telcordia may not be the best template. If you plan to put a 5ESS into a facility IBM may not be the best template. If you plan to put both into the same facility, things get a bit more interesting. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
Now that is a great analogy, I love it, right to the point. Henry Sean Donelan wrote:

No fight there! I was referring specifically [but did not say so..] to battery plants. No machines I have seen run on -48v as a CO does, so Ma's rules can not be an EXACT fit. But they at least HAD a Book. It is the cases where I see battery plant intermixed with ci$co routers and CAT-5 & such cable draped here there and everywhere, with loose ends flying around... that scare me shitless. Would YOU work in an enviroment where there was open 13.2KV with bare terminals under a collection of loose wires? Yet the battery plant on a big UPS will make just as big a boom. USDA on CO's? Is that like their book on stumps that HillCritters cite as an "Internet Bomb-making Source"...?? -- A host is a host from coast to coast.................wb8foz@nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
