Keywords: Ethernet, twisted pair, cost-benefit Message-ID: <1989Nov28.013425.16052@agate.berkeley.edu> Date: 28 Nov 89 01:34:25 GMT References: <4645@blake.acs.washington.edu> Sender: usenet@agate.berkeley.edu (USENET Administrator;;;;ZU44) Organization: University of California, Berkeley Lines: 30 I think the biggest loss with pulling thinnet to offices is when you think of the future. What happens when people change offices and someone moves in where you put thinnet. Well, if the new occupant(s) happen to want thinnet then you're fine. If they want something else you're going to have to pull something else. The labor costs quickly dwarf any material costs. Today there isn't much you can't do with twisted pair, including thick ethernet transceiver cable, MacIntoshes and PCs, IBM 3270 type terminals, etc. (I used to assume that FDDI would mean pulling fiber through the walls, but I've heard a rumor that at least one company is planning to try to design gear that uses twisted pair to the workstation for FDDI. If this can be done it'll be worth a bundle, you'd only have to pull the fiber into your phone closets.) In your case, since you're working from a very small perspective, then you may not care about the costs of pulling wires again and again.
