Here at Apple Computer we run six RJ-45's to each and every cube. We don't run eight wires to every jack though, only four. It covers our AppleTalk, twisted-pair Ethernet, proprietary PBX phones, analog phone lines, and ISDN lines. Be advised that most twisted-pair Ethernet and all ISDN basic rate interface lines I know of require an RJ-45 jack even though they don't use all eight wires. Our configuration is what I would call a minimum for any company that had voice and data needs. I also agree with Julian's motto of at least six pair and I also sometimes regret not pulling 25 pair. In short, don't take no for an answer from those who don't understand the real requirements. Wayne Correia (N6RSC) N&C Engineer Developer Technical Support Apple Computer, Inc.
