, documentation. In the above links must establish a sound document, as part of the acceptance.(Excerpt from: David's wiring bulletin board)Common mistakes in line playingThe common error of the line is open, short circuit, reverse connection (two of a pair of lines crossed, such as 1 corresponding 2,2 corresponding 1). Another error is bridging, such as 1, 2 corresponds to 3, 6. The main causes of this error are two. One end of the cable uses the

Structured wiring is now widely used in communications, finance, real estate, education, shipping and hotels and other industries. With the continuous expansion of wiring infrastructure, the management is becoming more and more complicated. The most difficult problem for the network administrator is to update the document record. Traditionally, wiring documents h

I. Overview Integrated Wiring is a modular and highly flexible information transmission channel between buildings or buildings. It connects voice, data, Image devices, and exchange devices to other information management systems, as well as external devices. It also includes all cables and related connection components between the connection points of the external network or telecommunication lines of the building and the application system equipment.

The implementation design of network integrated wiring project plays a decisive role in the whole process of wiring, and the design organization should be cautious. Preparation of wiring before usually network engineering after investigation, determine the scheme, the next step is the implementation of the project, and the first step in the implementation of

Internet cafes currently provide services, such as Web browsing, network games, online movies, distance education and other basic services are related to the network, the quality of the network directly determines the viability of Internet cafes. Therefore, how to plan a high-quality network environment, is an Internet café operators must consider a key point, the integrated wiring of Internet cafes accounted for a large number of factors, mainly two

User subsystem: The user subsystem consists of the connection of the terminal device to the information outlet, which includes connectors and adapters.Horizontal subsystem: A connection between the information socket and the management subsystem (jumper racks), which is commonly used in five or five types of 8-core 4 pairs of twisted-pair wires to achieve this connection.Management subsystem: The management subsystem is made up of interconnected and interconnected

Integrated wiring system emerged Architectural pursuit of integration, intelligence, broadband, personalized information and communication network, integrated wiring System (PDS) emerged. With the rapid development of FTTB and FTTH technology, the indoor cable has been widely used in the building integrated wiring system (including horizontal and vertical

How can we understand the electrical wiring of so many cables ?, So many electrical wiring Whose lines are not messy? As long as you have mastered the wiring rules, you can understand the line. What is the wiring rule? Generally, construction from the end of the line to the end of the line is recommended. Specifically

twisted-pair wiring. Many users in the wiring often appear one is to use one by one of the corresponding error connection method, when the connection distance is short, the system does not appear connection fault. However, when the connection distance is long, the network is busy or high-speed running, it is easy ..., its core is to let 3 and 62 pins for the same pair (according to

test of the wiring diagram verifies the connection relationship between the two ends of the line and the core of the RJ45 plug. In terms of contact points, the two Connection Methods T568A and T568B are generally followed. There is no difference in performance between the two methods, but the same method must be used for construction in the project. Wiring Diagr

NYOJ wiring problems and nyoj wiring problemsWiring Problem time limit: 1000 MS | memory limit: 65535 KB difficulty: 4 Description Nanyang institute of technology needs to transform the power line. The principal now asks the designer to design a wiring method which must meet the following requirements: 1. Power up all the buildings. 2. Minimum Co

Optimal wiring and wiring[Problem description] the school has n computers. To facilitate data transmission, we need to connect them with data lines. Two computers are connected by data lines. Because the computer is located in different locations, the connection fees for different two computers are often different. Of course, if you connect any two computers with data lines, the cost will be quite large. To

Experience Sharing: key points, difficulties and solutions for Integrated Wiring construction, and experience sharing Integrated Wiring For cabling systems, the main difficulty of construction lies in how to solve the problem of information outlet installation and positioning. Generally, information outlet installation is divided into three types: 1. Wall embedding and Installation Wall embedding and i

For the first two kinds of errors, the general test equipment can be easily found, the test technology is also very simple, but it is difficult to find the string around. The error occ

Integrated wiring system in China has more than 10 years of history, wiring engineering after 10 years of development has become increasingly mature, the performance of transmission media has been increasing, wiring scale is also more and more large, but cabling system management is often overlooked. We know that the flexibility of the integrated

Application System A system that transmits information in a way that can operate normally on an integrated wiring. Cable Cable refers to the information technology equipment connected to cables, optical cables and a variety of soft cables. Integrated wiring Integrated wiring is a information transmission channel composed of cable and related hardware, it can supp
