Hi, we have two buildings at about half a mile away each other. We would like to connect the two ethernets, using two kinetics and phonenet between them. In this way we could reach 230kbps between the two ethernets. The configuration should be: | | | +--------+ +--------+ | |--|Kinetics|----PhoneNet Cabling----|Kinetics|--| | +--------+ +--------+ | | | Building 1 Building 2 Ethernet Ethernet Is this reasonable ? What should be the configuration of the two Kinetics ? I know that it is possible to route IP packets. Is it also possible to get DECNET packets through in some way ? Thanks, Vincenzo. --------- capuano@sun.cnuce.cnr.it

The problem that you will run into is there is an absolute length of the PhoneNet cabling. You would need to talk to Farallon about this though.

Why not run ethernet thru the phone cable. You can do that as far as I know. Ethernet is faster than appletalk. Evelyn

However, without knowing more information about your network the best suggestion that I can make is that you look at the line of Shiva products. I have used the Shiva TeleBridge (two actually) to connect networks between two cities (only one FastPath, however). The distance between telebridges counts as virtually nothing when going through a high speed data line (ex. T1) and it probably will be the same effect with modems over normal data line (in lieu of a T1). Shiva will be able to answer that one for sure. -- ############################################### # Jeffrey H. West # # email: jeffw@ddsw1.MCS.COM # ###############################################

You would need to talk to Farallon about this though. PhoneNet quotes 4000' max. Should be fine. It would be worth getting someone to put a CRO (scope) on to the line to check out what the signal looks like. Can the FP route live IP packets (not just IP-in-AppleTalk) through LocalTalk, like from a Unix machine on one Ethernet to a Unix machine on the other? What is the set-up that allows this? ======================== Tom Evans tom@wcc.oz.au Webster Computer Corp P/L, 1270 Ferntree Gully Rd Scoresby, Melbourne 3179 Victoria, Australia 61-3-764-1100 FAX ...764-1179

On the other hand, AppleTalk PhoneNet is rated at 3000 feet (~1000 meters) and can actually go to 4000 feet without problems, especially if you use 22 gauge wire. 110 meters < .5 miles. 3000 feet > .5 miles. (BTW, I never really had enough appreciation for PhoneNet until I started doing UTP EtherNet. 10BaseT is wonderful, but the flexibility of PhoneNet after you've been dealing with UTP for a week is just amazing.) --- Alexis Rosen {cmcl2,apple}!panix!alexis alexis@panix.uucp
