The system structure is shown in the figure below.
Material Selection
Based on the user's needs, choose the company's wiring product as the main material for our system. The Panel adopts the 86-type panel exclusive to Lucent, which meets the requirements of the 86-level baseline box of the national standard. It is the same as the base box and Panel of the strong electrical system, and looks neat and beautiful.
5 categories of products are used for standard cabling. Each working space is a dual-hole outlet: A computer outlet and a telephone outlet (dual-voice plug-in for some workstations ).. The Cabinet end adopts the 48-port modular distribution frame of Lucent. Telephone and computer can be exchanged at will.
Recommended Route laying for pipe trough Design of cabling system:
· Because the unshielded twisted pair wires are installed and do not have high requirements on grounding, it is recommended that the cables be grounded at the Main Trough connected to the Cabinet.
· The specification of the cable slot is determined as follows: the cross-sectional area of the cable slot is 40% surplus for expansion, and the cross-sectional area of over 5 twisted wires is 0.3 cm².
· Note the isolation from strong electrical channels during installation. The cabling system should avoid having to walk more than 3 meters without shielding and distance less than 20cm from strong electrical lines. If it cannot be avoided, block isolation measures should be taken for the cable slot.
· The cable cables entering the furniture are routed from the nearest ceiling trough along the partition wall to the ground, and buried pipes are routed from the ground boring trough to the furniture partition.
· Pipe slot transition, interface should not have burrs, and Line Slot transition should be smooth.
· When there are more than two elbows in the pipe line, the split box must be left.
· The installation of the wall-mounted bottom box should be more than 30 cm away from the ground and be highly parallel to other bottom boxes.
· The Pipe series adopts galvanized Thin-Walled Steel Pipe or PVC pipe.
Detailed Design of subsystems
Workspace Subsystem
According to the design scheme: a total of 120 computer phone calls. A total of two ports and 60 panels are required, and there are 120 modules in the cat5e information module. Each computer point is equipped with a 3-meter jumper that can also be determined by the customer's requirements. The jumper must meet the M data transmission standard, and each thread must undergo five tests.
The work zone subsystem consists of jumpers and information sockets connecting terminal devices to the Information sockets. A computer or other terminal can be connected through the sockets. One end of the horizontal twisted pair is connected here. Each panel has over 5 types of sockets, And the sockets are mounted on the panel. Install it in each work location. 8-core RJ45 socket type. Jumper is used to connect a socket to a PC. The two ends of the Jumper have RJ45 plug. A dual-hole socket is required. Computers and telephones can be switched randomly according to users' needs. The sockets use the standard white square panel unique to longxun and have a special label card slot on the top of the port. These sockets have high performance, small Size, beautiful appearance, easy to install and other features; for the work area RJ45 socket, panel front view (diagram)

The V-A-B-C is the voice point number, A is the distribution frame number, B is the distribution frame port number, C is the total voice point number.
The D-A-B-C is the voice point number, A is the distribution frame number, B is the distribution frame port number, C is the total voice point number.
The serial number is also marked at the end of the Category 5 cables connected to the socket for future maintenance.
Level Subsystem
The horizontal subsystem is used to extend the main subsystem line to the user workspace subsystem. The level subsystem's data, graphics, and other electronic information exchange services will use four pairs of cat-5e unshielded twisted pair wires Cat. 5 UTP) cabling. Category 5 unshielded twisted pair wires are currently the best cost-Performance high quality transmission medium, its performance indicators fully comply with ANSI/EIA/TIA-568 standards, it can ensure that the transmission rate reaches and exceeds 100 MBps in the range of 100 meters. According to the design, the maximum distance of over 5 types of UTP for 100 Mbps transmission is meters, and the port from the distribution frame to the remote work zone is designed) is less than 90 meters.
Similar to computer cabling, telephone cabling allows the owner to conveniently manage and flexibly choose the jumper mode by setting a computer port and a telephone port at the same office location. At the same time, telephone and computer wiring are over five lines to ensure interchangeable.
The horizontal subsystem consists of 8-core unshielded twisted pair wires. Common twisted pair wires include three types of wires and five types of wires. Three types of lines can be used for telephone and 16 Mbps data transmission; over five types of lines can transmit data at a speed of up to 100 Mbps. To meet future expansion requirements and maximize investment protection, this solution adopts a category-5 line model.
The cables are connected to the Information sockets in each work zone from the Main Wiring room, that is, the data center. The information points of each region are extracted according to the specific layout. The principle is that each workstation is less than m away from the active network device. each cable is located near one end of the connection socket and has the same number as that of the socket for later maintenance.
In this solution, 8-core UTP cables are required for horizontal cat5e systems, and over 5 UTP: 16 boxes are required.
Trunk Subsystem
The vertical trunk subsystem connects data terminal devices, program-controlled switches, and management subsystems. In this project, all users are on two layers, so there is a vertical subsystem.
Management Subsystem
The distribution frame management module is used to connect with horizontal twisted pair wires. The advanced and common 19 "standard modular distribution frame is used.
The computer wiring uses a single hop mode, and the Jumper jumps between the hub and the distribution frame. Jumper adopts over 5 types of UTP and RJ45 connectors. We provide a unique HUB jumper with a yellow patch cord. Considering the fixed length after adjustment, each patch cord has undergone multi-index testing by five types of testers, it fully meets all patch cord indicators specified by the standard and supports data transmission rates exceeding MB. The patch cord is added at both ends of the patch cord to correspond to the number, which avoids inconvenience in future management and facilitates management.
To ensure the appearance and convenience of management, the standard 19 cabinets, wiring equipment and network equipment are fixed on the cabinets.
The distribution frame management uses a table to record the cabling routes based on information such as seats and Department units. It is identified to facilitate maintenance personnel identification and management. Various corresponding information tables are provided in the document.
Distribution Frame System: it adopts a cat5e, 24-port, or 48-port modular distribution frame.
Distribution frames are required for a single HOP: 24 ports and 6 ports.
Additionally, several jumpers are required to connect the distribution frame and data equipment.
19 "the upper part of the Cabinet is used to install the distribution frame, and the lower part is the space of network equipment used to install the HUB or switch.
Rack-based installation can facilitate the installation of network equipment, facilitate the management of a large number of jumpers, and have far-reaching significance for future equipment maintenance and management, and the use and expansion of network equipment.
