Backbone Cabling: Backbone cabling $($vertical cabling$)$ connects telecommunication rooms, centralized equipment rooms, and entrance facilities. It facilitates communication between different parts of the building or even separate buildings within the campus. Backbone cabling should be robust and capable of handling high$-$speed data transfer. Entrance Facility: The entrance facility is where the service provider$$s external cabling meets the private network cabling system. It serves as the consolidation point for data and communication services. Components include cable routing, network demarcation points, and surge protection devices. Telecommunications Rooms: These rooms house equipment $($such as switches, routers, and patch panels$)$ that manage the structured cabling system. The telecommunications room acts as the central hub for network connections within the building. Demarcation Point $($Demarc$)$: The Demarc is the physical dividing line separating the service provider$$s equipment from the customer$$s wiring. It establishes the network boundary between the external infrastructure $($owned by the provider$)$ and the internal infrastructure $($owned by Richfield$).$ Ideally, structured cabling should extend from the Demarc to the telecommunications rooms on each floor, ensuring efficient connectivity.
