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
