How does BICSI define OSP?

• A. External to buildings and typically routed into an entrance facility
• B. Inside the building and routed through the customer premises
• C. A wireless link between buildings
• D. A service offered by the franchise

Answer: (A)

Outside Plant (OSP) refers to the portion of the telecommunications infrastructure that exists outdoors, from the service provider’s network up to the building’s entrance facility. This includes cables, conduits, and hardware located outside the building and at the point where the network enters the building. Therefore, it is external to buildings and typically routed into an entrance facility, which is where the transition from the outside plant to the inside plant occurs. The other descriptions describe wiring inside the building, a wireless link, or a service offering, which don’t match the defined scope of OSP.
