Which of the following subsystems are involved in building cabling?

• A. Horizontal subsystem
• B. Access subsystem
• C. Backbone subsystem
• D. Vertical subsystem

Answer: (A)

The horizontal subsystem is primarily responsible for the cabling used in telecommunications within a building. It connects the telecommunications rooms or equipment rooms to the work area outlets, facilitating communication and data transfer between devices within the immediate vicinity. This subsystem typically consists of the cabling itself, such as twisted pair, fiber optic cables, and the necessary connectivity hardware, such as patch panels and outlets. It is designed to handle the distribution of voice, data, and video signals across a local area, ensuring that the various devices in different rooms or areas can communicate effectively. The other subsystems, while essential for a complete cabling infrastructure, serve different purposes. The access subsystem primarily focuses on connecting end-user devices to the network, the backbone subsystem handles the horizontal distribution of signals across larger areas or between buildings, and the vertical subsystem refers to the cabling systems that provide interconnection between different floors of a building.
