I know all that. I didn't explain all my reasoning because I assumed that folks here would know it all already. This is an existing apartment, wired with (I presume, since all other apartments I've been in have been wired this way) quad wire from the network demark to each wall plate. Normally I'd have one line... quad to the wall plate ... for the data line and the other wires... again, quad to the wall plate ... for the voice lines. Each cable is now one wire on quad. Crosstalk should be minimal, unless they run the quads next to each other in the same conduit for any significant length. With this setup, all the quads have both lines next to each other and some crosstalk is to be expected. It's a small apartment, so it might not be so bad. Sigh. Next time I ask a question I'll be sure to include full background on everything, my life history, and the whole shmeer... `-_-' Peter da Silva. +1 713 274 5180.
