The other day, my roommates and I wired up our very own 3-mac network in our room using TOPS TeleConnectors (DIN-8). (ooh ahh 8-) Anyway, my mac, which the other two are daisy chained from, is also plugged into our phone jack. So in addition to having our macs networked, we have phonelines split off of the TOPS connectors. We figured while we weren"t playing netgames, might as well have phones in each room too. What we found out was, that the phones are active even if we have net-active programs sending stuff from mac to mac. Correct me if I'm wrong anywhere... phonenet cables only require 2 wires, while the normal phone cables use 4 wires, 2 of which are power. Since both phone and appletalk work simultaneously over the same cables is the signal being converted to analog form? so that in essence, the voice and appletalk data are sent via different bandwidths? or if not, what really goes on? Thanks for any answers. Curiously yours, Tony Chen, adchen@phoenix.princeton.edu

(ooh ahh 8-) Anyway, my [runs Appletalk on same wire to which the phones are attached] My understanding is that Phonenet uses two wires, and the phone use the other two, of the four conductors in RJ-11 cable. Since the phone normally uses two wires, this is how the phone company can hook up a second line for you without major renovations. I thought about doing what you did when I hooked up my network, but my concern was that the Appletalk stuff would modulate the phone company network, and I'd get billed for calls to bizzare places! Can anyone clear this up for sure? Richard C.

Normal phone cables require two wires, (Tip and Ring), the inside wires on RJ-11 and RJ-14 jacks. PhoneNet style connectors require two wires, normally the next set of wires on the RJ-11 and RJ-14 jacks. For instance, I have wired up a network using 6 conductor phone wire,2 for the voice phone line, 2 for the data phone line, and 2 for AppleTalk. (I'm using dual-RJ11 (the standard modular jacks)) -- Matthew T. Russotto russotto@eng.umd.edu russotto@wam.umd.edu .sig under construction, like the rest of this campus.
