(1.0.1 With the development of urban construction and information and communication undertakings, the information requirements of various civil and industrial buildings such as modern commercial and residential buildings, office buildings, complex buildings and parks have become the development trend of urban construction. In the past, when designing the voice and data service lines in the building, various transmission lines, distribution sockets and connecting devices were often used. For example, the user telephone exchange usually uses twisted pair telephone lines, while the local area network (LAN) may use twisted pair or coaxial cables. These different devices use different transmission lines to form their own networks; Plugs, sockets and patch panels are not compatible with each other and cannot be shared with each other. Now it is possible to combine the wiring network of all voice, data, image and multimedia service equipment on a set of standard wiring system, and insert various equipment terminal plugs into standard sockets. In the integrated wiring system, when the location of the terminal equipment needs to be changed, it is only necessary to do some simple jumpers, and the office can be realized without the need to lay out new cables and install new sockets. The integrated wiring system uses a wiring system composed of shared accessories, which integrates various equipment from different manufacturers and works at the same time, which are compatible.)
