After the Demarc, which location houses the customer premises equipment connected to the WAN?

After the Demarc, the customer premises equipment that connects to the WAN is housed in the IDF, the floor-level distribution area that ties the building’s internal wiring to the end-user devices. The Demarc marks the boundary between the carrier’s network and the customer’s equipment, while the MDF serves as the building’s central backbone closet. The IDF sits closer to where end-user devices are grouped and is where the WAN-facing CPE (like routers and related gear) is placed. CSU/DSU is a device used to terminate the digital line, not a location, so it’s typically located with the CPE in the IDF.
