We recently installed Cabletron's MMAC with their AUI interface (two pairs, unshielded). It's been great. We didn't face the situation that many do, though, since we already had both thick and TP installed -- it's just that *adding* to the thick had become quite a hassle... In article <1647@frame.UUCP> you write: >If you have it, what do you feel is best about it? Ease of installation, management, debugging, and extension. >What is worst about it? Somewhat locked in to a single vendor for parts -- but this isn't bad as long as the company is stable. We've been so impressed with Cabletron's gear and both their technical and sales responsiveness, that we've started getting all our ether stuff from them. >Does it make adding new nodes easier or harder? MUCH easier if, like lots of buildings, the twisted pair is already installed. Even if it's not, stringing TP wiring is typically easier (and cheaper) than typical thick or thin. >Do you see any performance bottlenecks with it? Nope. There really should never be a "bottleneck" to it, since with CSMA/CD ether, there is always only one "talker"; the MMAC just has to do the CD part, then relay bits from a host to the "backbone". ---- Mark Foster CSE Systems Support Oregon Graduate Center Beaverton, OR fosterm@cse.ogc.edu

We recently installed EtherPlex in our offices. Much easier to install after-the-fact, especially since everything in this new building has to be plenum-rated. We'd used Etherplex previously and not found any performance bottlenecks that I was aware of. Mike Knudsen Bell Labs(AT&T) att!ihlpl!knudsen
