In recent times voice coupled with data cabling considerations have combined. Presently, cabling infrastructures have been made to support voice, data and video together with other building communications services that include video conferencing, cable tv and security applications for instance CCTV. The preferred cabling media in the UK is either unshielded or shielded balanced twisted pair cables which have progressed to a stage in development where a bandwidth of over 200MHz is now available. Data cables have eight wires or four twisted pairs, generally from a communications cabinet to an outlet. The cabling infrastructure contained within a building is known as Structured Cabling. This infrastructure as a whole is made up of a range of smaller elements commonly called subsystems. These subsystems include (but are not limited to): * Backbone cabling that typically connects between any entrance facilities, equipment rooms and also telecommunications rooms. * Horizontal cables typically connects telecom rooms to desired outlets on any floor. * The backbone and horizontal cabling is usually presented in the Telecom room. There may be several of these on campus sites or large buildings. Any design and installation associated with structured cabling is actually governed by way of a set of standards intended for data or voice communications, by means of category 5e or category 6 cable along with telecom outlets. (Cables might also be referred to as Cat5e or Cat6) These standards define just how to lay the cabling in a "star formation". This will mean that each of the outlets are terminated within the central patch panel (most of the time 19 inch rack-mounted on the inside of the communications cabinet in the telecoms room - also possibly called a server room). From this patch panel it will be decided in what way these connections will be used. An individual outlet is able to be 'patched' straight in to a data network switch, and even into a voice patch panel' that typically forms a bridge into a private branch exchange (PBX) telephone system - this makes the particular connection a voice port and not a data port. Present-day data cabling standards stipulate that all eight connectors in Cat5, Cat5e and Cat6 cable are connected, this means that you cannot really 'double-up' or make use of one cable for both voice and data. Structured cabling schemes give you connections from individual points throughout a building to a central patching position inside a communications cabinet. Voice switch, LAN hub and telecoms services usually are presented at the patch panel and peripherals could be cross-connected in order to deliver the necessary service everywhere they may be needed around the building. Structured Cabling is the life blood of your network. It is normally not deemed as important, but as more and more devices are now running over the cabling (CCTV, TV, Video, Voice & Data), more consideration should be made when installing a new network. Your company's cabling infrastructure can easily be configured and adapted to meet new demands, and can allow for any sort of moves office workers want to make, either individually or collectively, on a temporary or fixed basis. Additions, moves and changes to your structured cabling can be made very easily.
