The phones are those new fancy electronic merlin-type phones (excuse me, voice terminals) which use 3 pairs. This leaves the 4th pair free for me to run appletalk over, which is great, almost. The problem is that the wiring runs terminate in 8-pin modular jacks and PhoneNet is designed to pick up the outside (B/Y) pair of a normal 4-pin jack. I had thought of just mounting RJ-11s next to the 8-pin blocks and jumpering over with a short run of station wire, but they have insulation displacement connectors; no reasonable place to get at the conductors to run a jumper. So, what I need is the following adaptor. At one end, an 8-pin modular plug. At the other end, an 8-pin modular jack, with the first 3 pairs fed straight through from the plug. On the other other end, a modular jack with the 2nd pair patched through to the 4th pair of the modular plug. You plug this into the wall-mounted jack, plug your electro-phone into the feed-through jack and your Macintosh into the 4-to-2 patched jack, and you're all set. As far as I know, no such beast exists, nor is there anything like a RJ-patch-it-yourself kit (these sorts of things are popular with the RS-232 crowd).
