Premise Wiring is the cabling, connectors, and accessories that are used to connect LAN (Local Area Network) and phone equipment within a commercial building. Premise Wiring is standardized, this means that a governing body (in this case ANSI and TIA/EIA) set requirements regarding the minimum performance levels for products used as well as offer design and layout criteria that must be followed. The end result of a standard is that all the manufacturers are "on the same page" with regards to how they make their premise wiring products. Also, all cable installers should follow the same rules making it easier to troubleshoot and expand the wiring in the future.
To explain all of the details that pertain to premise wiring in one page is nothing short of impossible. Nonetheless, this page can be used as a primer for those who wish to understand things a little further. The first place to start is with common terms.
