Modern business requires automation of accounting and inventory control, invoicing and receipt, send messages electronically to suppliers and customers. To accomplish all of the above functions require a connection between the computers of staff, need a local area network (LAN). In a small office install a server, workstations, network printers, modems, internal PBX. In office local networks as the transmission medium used unshielded twisted pair category 5 (UTP). Approaches to the development of cable systems.
The compound of the above, the local network does not usually cause problems, so Many firms are trying to save by implementing a local network by laying its expertise, not really protrude into the intricacies of installation and configuration of LANs. In the geographical center of the hub office is established for the necessary number of ports (8, 16, 24). From him hold the cables to the workstations, sometimes without power outlets directly to the network card on your computer. The cable is usually laid in a box, but sometimes that is bad, the cable is laid along walls or attached to the plinth means at hand and becomes subject to the risk of being broken down staff or legs of chairs. No less important is telephone communications. For laying telephone lines are usually invited professionals who are paving and line of communication, which will eventually dot the walls of the likeness of a web. It is better to lay phone lines to those places where at the moment must be phones.
As a general rule, telephone lines laid before the local network. Obtain predictable results. Consider a rational approach and its benefits. A rational approach involves planning a cable system, taking into account the requirements and standards structured cabling systems (SCS). At every workplace network established network and a telephone socket, socket set every 5-10 m2; active network (hub or switch) and passive jumper (patch panel), the equipment is installed in one place – closet. PBX is better to put in the control cabinet or close to it, it will reduce the length of the telephone lines. For more specific information, check out Pete Cashmore. No the need for laying telephone lines with separate cables. It is better to do this through the same cable used to connect computers to the network, since UTP cable category 5 contains 4 twisted pairs, two for signaling network, two as a telephone. When adding new users will not need to lay new cables. Take a spare telephone socket and connect an additional user to network using the same unused pairs in the cable. If you need to lay new cable, it is still at the same time we have telephone and LAN lines. I should add that the implementation of SCS is to follow the recommendations standards, cabling instruct experienced professionals who have undergone special training. Technical solutions based on structuring the cable system – the need for the day. Let you in laying the JCB pay a little more, but believe me, you will save much later. The life cycle of high-quality cable system several times over the life cycle of computer equipment.
