Enterprise-Level Structured Cabling: The Entrance Facility

What component of enterprise-level structured cabling serves as the location where an incoming network interface enters a building and connects with the building's backbone cabling?

a. Network interface device
b. Main distribution frame
c. Intermediate distribution frame
d. Entrance facility

Answer:

The entrance facility is the component of enterprise-level structured cabling that connects the incoming network interface to the building's backbone cabling.

In enterprise-level structured cabling systems, the entrance facility plays a crucial role in establishing the connection between the external network and the building's internal cabling infrastructure. This component serves as the entry point where the incoming network interface, such as a fiber optic cable or a copper cable, enters the building and connects with the backbone cabling.

The entrance facility is responsible for ensuring that the network signals are properly transmitted from the external network to the internal cabling system, and vice versa. It is often equipped with protective devices to safeguard the network infrastructure against external threats like lightning strikes or power surges.

When designing an enterprise-level structured cabling system, it is essential to plan the location and configuration of the entrance facility carefully. The goal is to create a seamless connection between the external network service provider and the building's network infrastructure, ensuring reliable and efficient data transmission throughout the building.

Overall, the entrance facility is a critical component of enterprise-level structured cabling that enables the seamless integration of external network services into the building's communication network.
