Local Area Network (LAN) connects multiple computers, various peripherals (eg printers), and telephones. It is rather difficult to imagine a company that can completely abandon the local network, so as for a full exchange of information and correspondence and dialogue with the partners simply need telephone and computer networks. For the system to run smoothly, you need to take care of that construction of the building did not have any impact on signal quality. If the office grows, with it increasing, and the total load on the lan. Any company offering services of assembling networks lan is simply obliged to provide all these technical features. acs – a system of controlling access. The simplest example of such a system – a turnstile or door, which is mounted on a special reader. The main objective of the system access control – to allow any restrict employee access to any part of the industrial premises.
When the code is a plastic card meets the requirements of the reader, the door can be opened. Virtually all of the acs have certain crossing restrictions on the number of users. Therefore, the choice of devices is necessary to consider not only the current situation in the business center, but be prepared for possible changes in the short term. scs – Structured Cable Network, are combined into a single unit phone lines and LANs. It is worth emphasizing that, in most cases, the scs and lan – the concepts are interchangeable, because their main task – make the work of organizations in the business center effectively, providing absolutely every employee access to the Internet and the telephone line. Today there are two main approaches to the issue of construction and design of scs. The first approach meant by a current capacity, and the project is developed based on the current network load. The second approach is more costly, but in the future, it makes it possible without significant problems increase the burden on the entire network even in the event of a significant increase in staff of the company. Most of the firms that specialize in laying the scs, use just the same the second option. The same applies to access control installation – aiming for as low as possible cost process equipment must not forget about the possible admissible changes in the business center. Ensure efficient operation of companies in the business center – a task far from the most simple but nevertheless doable. Properly installed and designed systems and lan access control system will solve many current and more problems are expected with no loss of time and effort.
