What is the Integrated Wiring System and Its Features?

Introduction to Integrated Wiring System

The Integrated Wiring System (PPS), Premises Distribution System) is designed for computer and communication wiring systems. This shows that it can meet the requirements of various computers and communications. It includes:

1) analog and digital voice systems;

2) high-speed and low-speed data systems;

3) image data to be transmitted, such as fax machines, graphic terminals, and mappers

4) Video Signals of video conferences and security monitoring systems;

5) Transmit 28 high-frequency wideband video signals;

6) Integrated Wiring for building security alerts and sensor signals of Air Conditioning Control Systems.

It can meet all the computer, communication, and wiring requirements of building automation Integrated Wiring System equipment within and between buildings. Because the PPS is a comprehensive system, you can use the same cables and wiring terminal boards for integrated cabling, and the same plug and modular Jack for voice and data transmission, you do not have to worry about the compatibility of various devices.

Because of its modular design, the service is easy to expand and re-combine on the wiring. The use of star topology, and telecommunications and EIA/TIA-568 follow the same building wiring method. In the star structure, the workstation is added from the center node, and each line is independent of other lines. Therefore, only the route associated with the device is affected when the device is changed and reconfigured, but not all other lines. In addition, this structure makes fault analysis in the system very easy. Once the system fails, the fault point can be quickly found and eliminated.

Consists of six independent sub-systems. It adopts a star structure, which allows any sub-system to enter the PDS system independently.

The six subsystems are:

1) Workspace subsystem Work Location) It is composed of devices connecting terminal devices to information sockets, including information sockets, plug-in boxes or panels), soft wires, adapters, etc.

2) Horizontal subsystem Horizontal) its function is to extend the trunk subsystem line to the user's work zone. The horizontal system is arranged on the same floor. One end is connected to the information outlet, and the other end is connected to the hop frame of the layer-based fitting room. The level subsystem mainly uses four pairs of unshielded twisted pair wires, which can support most modern communication devices. In some scenarios that require broadband transmission, the "fiber-to-desktop" solution can be used. When the horizontal area is very large, there may be one or more satellite connection rooms in this range. In addition to connecting the horizontal line to the equipment, the horizontal line must also be connected to the satellite connection room, connect the terminal to the Information exit.

(3) trunk subsystem Backbone) usually consists of the master equipment room (such as the computer room and the Programmable switch room) to the management room at each layer. It uses a large number of cable feeders or optical cables, and the two ends are connected to the Jumper frames between devices and management rooms.

(4) The Inter-device subsystem (Equipment) is composed of cables, continuous jumpers, related supporting hardware, and lightning protection devices. The ideal setting is to design equipment rooms such as computer rooms and switch rooms on the same floor, which facilitates management and saves investment. Of course, you can also design multiple equipment rooms based on the specific circumstances of the building.

(5) Management Subsystem Administration) it serves as a bridge between the trunk subsystem and the horizontal subsystem, and can also provide conditions for the same-layer networking. These include the twisted pair wire jumper, patch cord, and simple patch cord ). In the cabling system that requires optical fiber cables, there should also be optical fiber jumper frames and optical fiber jumpers. When the location of the terminal device or the structure of the LAN changes, you only need to change the jumper mode to solve the problem without re-wiring.

6) consortium subsystem Campus is a cabling system that connects Data Communication Signals of multiple buildings. It uses copper cables and optical cables that can be installed on an overhead or along underground cable pipes or directly buried, as well as electrical protection devices that prevent the Surge Voltage of cables from entering the building.

Features of Integrated Wiring System

Compared with traditional cabling systems, integrated cabling systems have many advantages. They are mainly manifested in the following aspects:

1) compatibility the so-called compatibility means that its device or program can be used in a variety of systems. The Integrated Wiring System uniformly plans and designs the distribution of voice signals, data signals, and image signals of monitoring equipment, and uses the same transmission media, information sockets, communication equipment, and adapters, integrate these different signals into a standard cabling system. Compared with traditional cabling systems, this saves a lot of material, time, and space. In use, you do not need to define the specific application of the information outlet in a work zone. Instead, you only need to connect a certain terminal device to this information outlet, then, patch cord operations are performed on the device connecting the Management Room and the device. The device is connected to its own system.

2) the traditional open cabling method selects a certain device, and selects the appropriate cabling mode and transmission medium. If another device is replaced, all the original cabling systems will be replaced. This adds a lot of trouble and investment. Because the Integrated Wiring System adopts an open architecture and complies with a variety of internationally popular standards, it is open to almost all famous manufacturers, such as IBM, DEC, and SUN computer equipment, switch devices such as AT&T, NT, and NEC. And is also open to almost all communication protocols, such as EIA-232-D, RS-422, RS-423, ETHERNET, TOKENRING, FDDI, CDDE, ISDN, ATM and so on.

3) in flexible integrated cabling systems, all information channels are universal because all information systems use the same transmission medium and physical star topology. Each information channel supports telephone, fax, and multi-user terminals. The 10Base-T workstation and the licensing ring workstation adopt five connection schemes, which support 100Base-T and ATM. The activation and change of all devices do not need to change the system wiring, you only need to increase or decrease the corresponding network device and perform necessary jumper management. In addition, the system networking can be flexible and diverse. Even in the same room, there can be multiple user terminals. The 10Base-T workstation and the licensing ring workstation coexist, providing necessary conditions for users to organize information.

4) Reliability Integrated Wiring System uses high-quality materials and composite crimping to form a set of high-standard information channels. All devices are UL, CSA, and ISO Certified. Each information channel must adopt a physical star topology and point-to-point connection. Any line failure does not affect the operation of other lines, at the same time, it provides great convenience for line operation and maintenance and fault repair, thus ensuring the reliable operation of the system. Each system uses the same transmission medium, so they can be used as backups, improving Backup Redundancy.

5) Advanced Integrated cabling systems use fiber-optic and twisted pair cables to form a complete cabling system. All cabling adopts the world's latest communication standards, information channels are according to the B-ISDN design standards, according to the eight-core twisted pair configuration, through 5 category twisted pair, the maximum data rate can reach 155 Mbps, for special user requirements, optical Fiber can be deployed to the desktop Fiber -- to the Desk ). Trunk cable can be designed with a bandwidth of Mbps, providing sufficient margin for future development. Multi-channel real-time multimedia information can be transmitted through the main channel at the same time, and the physical star cabling method lays a solid foundation for the future development of the exchange network.
