1. Work area subsystem WORK AREA SUBSYSTEM
Workspace subsystem information from the terminal equipment connected to the outlet connection (or cords) composition, which includes assembling the wiring, connectors and extension cords needed to connect, and terminal equipment and I / O bridge between. Information output standards-compliant ISDN RJ45 8-core socket, according to the user’s use of the environment selected embedded, desktop, carpet-type or universal-type socket, according to network terminal equipment interfaces use the appropriate adapter.
2. HORIZONTAL SUBSYSTEM subsystem level
Sub-line stand by the district (IDF) to all the area information output connections. Horizontal cabling subsystem is a part of the entire cabling system that will extend the trunk line subsystem to the user workspace. Route cabling subsystem and subsystem level difference is: in a horizontal cabling subsystem is always on the floor, and termination in the information outlet. SYSTIMAX SCS using 24AWG twisted pair (UTP) for the transmission medium for data and image transmission, using CAT5 twisted pair (1061) or CAT5 + (1071) over five twisted pair, part of the transmission bandwidth and high-speed data have higher expectations of information transfer point,
Can use fiber to the desktop (FTTD) mode settings. Voice and control signals for transmission, using CAT3 twisted pair (1010).
Cable length estimation formula:
LT = [(Lmax + Lmin) / 2 + H] * 1.15 * N
Lmax terminal equipment to the floor farthest distance between the floor device
Lmin terminal equipment to the floor recently the distance between the floor device
H: The floors tall, the height of the program involved to 4 meters.
1.15: cable cut margins and line redundancy for the long length of 15%
N: number of information points in this floor (voice-point number and the number of data points and).
