Which telecommunication space generally houses equipment serving an entire building or campus?

The equipment room (ER) is designated as a central location within a building or campus where critical telecommunications equipment is housed. This space typically contains large-scale equipment such as servers, routers, and switches necessary for the operation of the entire telecommunications system within the facility.

Unlike telecommunications rooms, which may serve specific floors or smaller areas within a building, the equipment room serves a more comprehensive role by facilitating connections for multiple systems and often contains the main distribution frame (MDF). This central hub is crucial for managing and directing telecommunications cabling and services throughout the building or campus effectively.

The equipment room is also equipped to handle larger power and cooling requirements due to the density of the equipment housed within it. This makes it distinctively suited for serving an entire building or campus, making it the correct choice for this question.
