In most offices this is sufficient to create a local network. But if your use of the building of several floors or branches of your organization are distributed over a large area, there is a need to create multiple switching centers (the length of the horizontal segment of the SCS should not exceed 90 m). Combining switching centers in a single structure is just the backbone subsystem RAS. Creating a local network in the office on the basis of the horizontal link. You have entered into a new office or you're tired of tripping over cables scattered on the floor and decided to make repair. It is best to mount the SCS is at the moment of repair, where no walls or ceilings have not sewn, and it greatly simplifies the task of laying the cable runs. The first step is to determine the number of jobs and their location, because this will largely determine the method of laying cables.

Keep in mind that every computer, fax, printer, MFP, or any other office equipment is required not only to plug a computer network, but also conventional electrical outlet, and the same, so all the jobs must be equipped with at least a 2-port computer connection and no less than by 2 electric. Ideally, a standard electrical outlets should be divided into those that will be used only for computer equipment and outlets for household appliances, to your "employee", having decided to make coffee, do not accidentally arranged a short circuit that would lead to loss of data on all working computers. If you are not one hundred percent sure of the location of jobs, the best way is to install the cables of cable channels along the walls, with the possibility of moving the set of sockets the entire length of the cable channel. But there is a possibility and a hidden cable routing. Having determined the location of jobs and the way they are installed, all the cable lines are drawn for the ceiling and laid on hidden opportunities to the nearest telecommunications center. The method of laying tracks can be a double or a corrugated tube or by using the main tray. All the tracks have to be consolidated into a single telecommunication center.

In the simplest case, the telecommunications closet (TS). The cabinet can be wall or floor, depending on the installed equipment in it. If you want to place in the TS than patch panels and switches in the network and server hardware PBX, it is best to use the floor TSH in a special room for it. To Noise active equipment is not diverted from of employees in your organization. In TS all cable runs that came from jobs, reduce the so-called patch panels. Your system administrator, using ropes, bridged output switches to the inputs patch panels of the jobs, thereby closing the loop network. If the room is your office PBX, it makes sense to install it next to TSH or to himself. Then the internal telephone lines, which gives the PBX you can easily "embroider" in the same patch panels and then using conventional patch cords, you can apply the internal phone numbers to the right jobs. And finally want to say a few words about the power supply of telecommunication center. It is desirable, and if the server must be powered with UPS TS. Do not leave the performance of work on installation of SCS lovers. Remember Russian proverb: "Miserly pay twice?" Trust only the professionals.
