The days of one phone line in your home seem a long distance away. To get yourself hooked up for some easy solutions for your home communication needs, consider this tip. Most telephone wiring can handle more than one phone line, because it contains multiple conductors. Typically up to four lines can be wired through a single cable. This can allow for faxes, modems and other needs. You can adapt these lines yourself, with a little guidance and the proper tools.
