Hi, I'm collecting information on any experiences running Banyan Vines or Novell (or any net os) on twisted pair wire. My problem is that I know there is 4 pair wire in the walls but the type and quality is unknown (I know its not IBM type 3). Some of the solutions I've read about include: Pronet 4 on type 3 cable 3com's pair tamer Starlan (not really in the running) Any info on the above or others would be greatly appreciated, I'll summerize and post to this news group (I know others are interested). Thanks in advance, roy rutgers!pyrnj!roytar!syntrex

Normal proteon wire is two twisted pairs with grounds. The stuff proteon supplies in the 75meter lengths is pretty flimsy stuff, so you might be able to get away with it. One pair is a differential of data going to the interface, the other from. Power is provided to wire centers via DC bias between ground and one pair, and the join ring signal is DC bias between ground and the other pair. -Ron

> Starlan (not really in the running)
HP is selling some "Starlan-10" equipment, which is 10Mbit Starlan.
In particular, there is a Starlan-10 to Ethernet bridge (HP 28647A).
I expect that the engineers looked at the RFI aspects, since HP seems
to be pretty careful about standards. Other equipment from that
division (Roseville Networks) has been very reliable, so I expect the
bridge to be solid. We do use the 28645A ThinLAN Hub (a five-way
repeater with one thick tap and four BNC's) all over the place.
I expect that you can get proper information about these from an HP
sales office.

Yes, I know there is a four-pair connector on the AT&T Starlan board, but it only uses two pair. You can run Novell Netware on it, or the AT&T Starlan software (which they bought from 3com). -- Dave Levenson Westmark, Inc. A node for news.

The good news is that 10M StarLAN (or UTP Enet, Unshielded Twisted Pair Ethernet) has an excellent chance of becoming an 802 standard. This technology is really StarLAN speeded up and refined. You have a transceiver with an AUI interface to your host (or the xcvr is mounted internally) and a RJ interface to your wall. In your wiring closet is a "concentrator" (really a UTP multiport repeater). In many respects this technology, if successful, could become a replacement for the thin coax architecture. The wonderful thing about this technology is that in many cases the wire is already there and it's the same wire you already use for async terminals and telephones. We have a hundred years experience with this stuff. But standards are important. You want to be able to buy workstations from your favorite vendor and plug them into anybody's concentrator and make them work. I wouldn't buy anybody's product now if they couldn't tell me they would make it conform to the standard (if it doesn't already). H-P, Ungermann-Bass, Synoptics, Wang, Micom-Interlan and possibly others are already in the standards process with 802. It's anybody's guess how long it will take to have a standard, but it seems that some of these vendors are confident they know what the technical specs will be. I am looking forward to getting this stuff and running all my Ethernet workstations on it (when the price is right). -- ------------------------------------------------------------------- Kent W.
