Definition of Integrated Wiring

Premises Distributed System (PDS) is an integrated general-purpose transmission System that uses twisted pair wires or optical cables to transmit information within buildings and campuses, A structured information transmission system that connects devices such as telephones, computers, conference TVs, and surveillance TVs. Standard twisted pair wires and optical fiber cables are used to support high-speed data transmission. Using a physically Layered Star-type topology with modular design and unified standards, the service makes centralized system management possible, the failure, modification, or addition/deletion of each information point does not affect other information points, making installation, maintenance, upgrade, and expansion very convenient, and saving costs.

Currently, EIA/TIA-568, ISO/IEC 11801, EIA/TIA TSB-67 are widely followed in the field of integrated wiring. The Integrated Wiring System is divided into six subsystems:

1. Connecting subsystems of buildings and buildings;

2. sub-systems between devices;

3. trunk (vertical) subsystem;

4. Management Subsystem;

5. Level subsystem;

6. workspace subsystem.

The workspace subsystem provides a connection from the information outlet of the level subsystem to the user terminal device. It includes the expansion cables required for assembly, connectors, and connections, and overlaps between the terminal device and the input/output (I/O.

The level subsystem is composed of the wiring cables from the wiring room to the information outlet and the information outlet for the work area. Including twisted pair cables and information sockets.

The trunk (vertical) subsystem is composed of the interconnection cables between sub-systems, management sub-systems, and the Introduction ports of sub-systems. It is the trunk cable in a building and is collectively referred to as the vertical trunk cable between floors. The Inter-device subsystem is a place where cabling equipment and main distribution frames are installed in appropriate places in the building, and the cabling system is managed and maintained. The Inter-device subsystem shall consist of various devices such as voice, images, and data, as well as their distribution devices and main distribution frames.

A management subsystem consists of wiring hardware and input/output devices in a wiring room. Each wiring room and wiring room have a management subsystem.

The main subsystem of a complex is a complex integrated wiring system that connects the transmission medium between buildings and various supporting equipment through cables between buildings.

A standard distribution system integrates all the voice, data, images, monitoring, and other devices, and inserts the terminal plug of multiple devices into the standard information outlet. Any socket can be connected to different types of devices, which is flexible and practical. It adopts modular design, and the cabling system is inherent outside the horizontal cables in the building. All the other connectors are modular standard parts, which are easy to expand and reconfigure. When wiring needs to be added due to development, the entire wiring system will not be affected and the user's previous investment in wiring can be guaranteed. It provides a set of practical, flexible, scalable, and modular media channels for all speech, data, and Image devices. The interfaces used by the PDS System and the Integrated Service Digital Network (ISDN) interfaces are the same eight-pin module sockets and four-pair internal leads, and the data transmission rate supported by the PDS is higher than that of the ISDN base group. As a result, you can directly develop an ISDN instance using the PDS and the current telephone network without additional wiring.

Because the integrated wiring system replaces a single, expensive, and complex traditional wiring system, it is the requirement of the "Information Age" and the necessity of historical development.

In addition, the latest Integrated Wiring standard can take Gbit/s on Category 5 twisted pair wires, and the corresponding switching devices are gradually maturing. From a long-term perspective, the Integrated Wiring System can fully protect initial investment and meet the needs of system expansion.

Integrated Wiring Design Standard

The level-1 standard can meet the requirements of high-quality high-frequency broadband and integrated business digital communication.

(1) Each work area (5-10m2) has at least one dual-hole or porous 8-core information outlet.

The dual-media hybrid information Jack with multiple jacks can be used in special work areas.

(2) cross-connection hardware using a crimping jumper or a plug-in jumper.

(3) The distribution subsystem uses five unshielded twisted pair wires, five shielded twisted pair wires, over five twisted pair wires, optical fiber cables, or hybrid networks.

(4) trunk lines are connected by a combination of copper and optical cables, or all of them are connected by optical cables.

(5) the corresponding information Jack of each work area has an independent horizontal wiring cable leading to the floor distribution frame.

2) 2 pairs of 150 Ω shielded twisted pair wires (STP) Access shielded information Jacks;

3) standard interfaces for connecting 62.5/125 μm optical fiber cables to optical fiber cables;

4) The dual-media Hybrid Cable is connected to the dual-media hybrid information outlet.

The computer management system of the Integrated Wiring System should be able to record the working status information of various hardware facilities at any time.

Display: floor plan, all hardware, device location, distribution subsystem and trunk subsystem component location.

In the case of co-frequency interference, shield cabling systems should be used. Non-shielded wiring and the proximity of the TV cable may cause co-frequency interference.
