Has anyone out their had any experience with 10mb twisted pair ethernet (ie;Synoptics, Cabletron, HP, UB, AT&T etc) co-existing with voice (ie: PBX and/or Centrex) in the same wire bundle (ie; voice/data in the same 4 pair PDS wiring or 25 pair). I'm most interested in experience with Synoptics, I've been led to believe that, because their signalling is only 1v pp that the Ring Indicator on the voice circuit would drive it crazy. Please e-mail to: uunet!john_robert_breeden@cup.portal.com

We have a 60+ node LAN running completely on SynOptics 10MB twisted pair. The data runs over two pairs of a 4-pair D-station wire. The other two pairs are used for either voice, or some other data (occasional VT-220 terminal). We don't have any problems with voice on the same wiring. Our phone system in an NEC 2400 PBX, and some of the phones are even digital, and THEY don't even seem to bother the LAN. ------------------ Jeff Autor jsa00564@uxa.cso.uiuc.edu Student at the University of Illinois Also affiliated with Valmont Electric Opinions expressed are my own.
