First of all, you should understand the definition of integrated wiring: integrated wiring is a modular and flexible information transmission channel within or between buildings. Through it, voice equipment, data equipment, switching equipment and various control equipment can be connected with the information management system, and at the same time, these equipment can be connected with external communication networks. It also includes all cables and related connecting parts between the connection point of the external network or telecommunication line of the building and the application system equipment. Integrated wiring consists of different series and specifications of components, including transmission media, related connection hardware (such as distribution frame, connector, socket, plug, adapter) and electrical protection equipment. These components can be used to build various subsystems, and they all have their own specific purposes, which are not only easy to implement, but also can be upgraded smoothly with the change of requirements. Nowadays, many companies only regard network and voice (that is, telephone) wiring as integrated wiring.
Do you think telecom is capable of doing many things? As far as I know, there are hardly any!
Large units generally choose their own professional weak current companies to do it. But now telecom and other units will give owners free network and voice wiring, and then recover the cost through telephone charges. This is why many so-called integrated wiring now! But many telecom networks are far from meeting the needs of owners! So the owner does it himself! Of course: if it is a school, some enterprises and other units that don't have high network requirements, it can also be recommended to telecom, which can save costs, but the consequence is that the property right belongs to telecom, and you can't change operators:) Of course, in order to receive more business, telecom may threaten the cooperation and connection problems of the owners, which is actually nonsense. . . .
Just say so much hope to help you!
