I'm a little bit dismayed that 50-pin connectors weren't included in the 10BaseT standards. Every set-up has its nuance, but, I've been in closets were 400+ workstations were connected. 400 cross connects are much nicer than a mass of RJ45 jumper cables. I'd bet there are more machines running with 50-pin connectors than the DB-9 connectors included in the standard (Maybe I'm missing a large market, like defense related industries?). I'll agree its always desirable to limit the number of connections in the chain. We use one cross connect, from "station" to "data" in the loop and it works quite well. -- jens@corp.mot.com Voice: (708) 576-3312 UUCP: uunet!motcid!jens
