“Think for yourself, decide for yourself …”
Until now, we have considered solutions that save money when organizing the LAN of a small office due to some compromises with standards. There is another way of organizing the office cable system, not designed to save money by the methods discussed above, but rather, assuming some of their redundancy at the initial stage, but giving savings later.
This method of construction is used for dynamically growing firms and is gaining more and more approval among managers who are able to look at least a step ahead and know how to count money. With this construction, we do not violate any canons for SCS, do not get rid of “unnecessary” equipment and do not save on cable. On the contrary, all of these elements are abundant in our system. The idea is very simple: at each workplace, according to all installation rules, two RJ-45 information sockets (or a dual socket) are installed, to which standard horizontal cables of category 5 are connected, terminating on the patch panel in the cabinet. Having such redundancy, we can, at our discretion, based on current needs, connect to these outlets: two workstations, a workstation and a telephone from the PBX or two phones. All switching takes place in one place on the patch panel of the cabinet. The input city lines should also be displayed on the patch panel. This is useful in the event of a technical failure of the PBX. In this case, using standard telephone cords, input telephone lines are directly issued to the most critical workplaces. Any engineer can do this without resorting to the help of telephone services. It will take up to 5 minutes to switch. And when will the telephone operators arrive? Office without communication – money down the drain. There is no secret here. The standard (TIA 568 A (B)) cable layout in the eight-pin RJ-45 jack is compatible with telephony requirements, and the standard six-pin telephone plug is compatible with the eight-pin modular jack. When adding new employees, there are also no special problems, and there is no need to call installers to lay new lines.
For these purposes, in most cases, you can use the second socket of the workplace of the nearest employee who does not have a phone. Provided that in the project we have laid some redundancy of outlets, then such a technical solution to the cable system seems to us the most correct and not contrary to standards
