We really like the cheapernet because it is easy to work with and because making cables is REAL easy. You don't have to go out and buy transceiver cable. The problem though, is that most of the equipment that is on our net is 'old' style transceiver connector type which means that we (the Univ.) have to not only buy transceiver cables, but also a "thinwire-to-transceiver" converter (like DEC's DESTA). We do have some new SUN's that have the thin wire connector built in, along with the 'standard' transceiver connector. This is REAL nice because it gives us the option as to use either. More to the point of your question. I think that as more and more equipment starts to have the thin wire option (cheapernet), more and more people will be going to thin wire, namely because it is easier to work with. Some of the problems with thin wire that we (the Univ.) see are that the cost of a thin wire repeater (DEC's DEMPER) is around 10 times that of a thick wire version (DEC's DELNI). For example a DELNI is, and this is REAL rough, around $800 while a DEMPER is around $8000. I don't know if this helps or not but......... -- @__________@ W.

You may have been forced to buy a bridge to go with your DEMPR until recently since that was the only configuration that DEC could guarantee would work. Cabletron's DEMPR is $2795.00 list. I am sure DEC is in that range too. I hear that you can now order them w/o bridges.-- -------------------------------------------- | Kent W.

I am sure DEC is in that range too. I hear that A second point - DELNI's are not repeaters - they are fan-out boxes for transceivers. A DEMPR (or its equivalent) handles up to eight different segments of thinwire, each up to 185 meters, and repeats all of them onto the main cable. The boxes are not equivalent. -- Bill UUCP: {seismo|ihnp4}!harvard!cfa!wyatt Wyatt ARPA: wyatt@cfa.harvard.edu (or) wyatt%cfa@harvard.harvard.edu BITNET: wyatt@cfa2 SPAN: 17410::wyatt (this will change in June)

The DN3000 may be configured with an 802.3 controller which has a built in Thin-Net BNC and a connector for the transceiver cable on Thick-Net. Older installations seem to hook to the Thick-Net and newer installations go either way. Incidentally, Domain Data Services are now available on a Native Ethernet connection.
