Which space classification corresponds to CM?

Explanation:
CM stands for Communications Space, which is tied to the way cabling is distributed vertically in a building. Communication spaces are typically located in vertical pathways that run between floors—the risers. Riser spaces are designed to carry cabling between levels and require appropriate fire-stopping and cable ratings to prevent flames from moving upward. That’s why the space classification that corresponds to CM is riser. Plenum spaces are for air-handling areas (plenum-rated cables), general-use is for ordinary rooms, and outdoor is exterior locations.
