Am looking for real-life experiences with implementing FDDI concentrators, specifically the ones from Network Systems Corp. Know of 7 other vendors (AT&T, DEC, Timeplex, Synernetics, Summit Microsystems Corp., Interphase Corp. and Network Peripherals, Inc.) Would be interested in hearing why someone chose one product over the other.....are people just choosing the least expensive, the one that's been on the market the longest(sense of reliability for new technology), the only dual-MAC implementation, etc.

Their concentrators have 3 MACs (dual-MACs plus an additional Roving MAC) and with a capacity of up to 60(?) Ports. Give them a call. In chosing a concentrator, you might want to seperate concentrators into two groups. One is small workgroup type of concentrators (8-16 Ports) and the other is the large backbone type of concentrators (40-80 Ports) for the whole building. In a workgroup concentrator, you might just want to pick the least expensive ones. But for the large ones, I think that you should pick one that can be expand easily and also has VERY high fault tolerance. Oh, live insertion of boards might be useful also. (Live insertion will not bring down the whole network if you need to exchange only one of the board.) -- Mike Yip my@berlioz.nsc.com

Cabletron is selling FDDI concentrators also. -- Mike Yip
