In the described network, the IDF houses the customer premise equipment. Where is the IDF located relative to the Demarc?

The boundary point (demarc) marks where the provider’s network ends and the customer’s begins. The MDF serves as the central distribution point inside the building and connects the Demarc to the IDF on each floor. The IDF houses the customer premises equipment and is located on the customer side of that boundary, typically in a data or telecom closet, with cables run back to the Demarc through the MDF. So, relative to the Demarc, the IDF is inside the building on the customer side. The CSU/DSU is used to connect to the WAN, not to determine where the IDF sits.
