Whether the project involves establishing a voice and data structure for a single location or a series of interconnected locations, it is important to begin with the basics. The process will begin with the wiring at each of the locations involved in the network. If your company is building the facility from the ground up, then you will want to prewire the office. When doing so, make sure that the structured cabling wiring will support typical voice communications like basic telephony. You also want to ensure that the low-voltage wiring can support advanced data communications that is capable of supplying bandwidth for everything from a robust Internet connection of some type to high speed transfer into, out of and within your network. Most structured cabling systems use category 5 cable for the entire system. These systems are often installed by the interconnect who provides the telephony system or a contractors who specialize only in structured cabling systems.
