Some electrical/building codes are very strict with such things as wiring and the drilling of holes. Care should be taken with structural members of the building and compromising the weather, vapor, and other such barriers. Sealing of vapor barriers in the house is important and with the possibility of insulation within walls care should be noted here as well.

Plan your new wiring to use as many inside walls as possible is sound advise. All walls can be wired but by far and wide the inside walls are the easiest. Follow the rules of category 5 or better routing and affixing the wire to the building. If I may state the Canadian Electrical code states the wire of a class 2 nature must be firmly attached to the building structure and allowing reasonable access. In other words do not run it across the attic access so to not allow reentry to the attic. Use wire that has a suitable or better fire rating for your local code (FT4) and keep it away from any moving parts (doors, windows, fans, blowers, etcetera).
Common sense should prevail and if you can conceal the wire all the better. When drilling into a wall to route it through, carefully consider if there is any pipe or power wire in this area. More later on page 3.

I will talk about jacks and such later but first the placement of the wire and the type of wire is your primary consideration. Some if not most recently built houses have a 4 wire jacketed type of cable likely for cost reasons alone. This would be fine but only for short runs and may prove perhaps useful but it could be better. Consider the following, for each AppleTalk location you need 2 wires, for each phone you need 2 wires (city located, not rural party lines), and for each channel of the stereo you need 2 wires. If the need in a particular room would be only a phone and AppleTalk then the 4 wire cable would be fine. Or if just AppleTalk and nothing else then say no more.

So for lets say the den or what ever part of the house you call the place where the Mac / server will be, you need for the best situation 8 wires. The most common wire sold today is just what you need. A spool of 4 pair BDN is my favorite which in english is a category 4 type of inside wire that is way over rated for this type of job and the price is better than cat 5. It has 8 wires arranged in twisted pairs each with unique markings. The markings are thus:

Of course all the wires above have names other than the colors but lets leave that for another day. For our purposes lets call the colors "bw" for the blue/white and "wb" for the white/blue and so on. This way we won't get mixed up and everything is clear. I should mention the polarity is very important with some phones but the AppleTalk does not seem to be bothered by reversals. It just good workmanship to keep everything in order and it will make it easier to understand at a later date after you have long forgotten all about this and with it comes certain bragging rights with a job well done.

NOTE: As above I mentioned the twisted pair idea and the possible need for this. Long runs of wire and different signals on the conductors can leave small trace signals to adjacent conductors. With this in mind and keeping up to date the old 4 wire (green, red, black, yellow) cable is not up to snuff. If this piece of cable is used for the AppleTalk exclusively then fine, but if you want the phone on this cable as well then be prepared for perhaps a bit of crosstalk. This is a telephone term meaning if a cable has a slight signal heard from a close or adjacent signal there is crosstalk or induction if you wish. AppleTalk signals are heard as high pitched squealing noises and if this is heard over your phone conversation it could be grating on the nerves.

Look to the trouble shooting page (7) where this will be discussed.
