The following table describes the components used for wiring distribution: Component Description Demarcation point (demarc) When you contract with a local exchange carrier (LEC) for data or telephone services, they install a physical cable and a termination jack onto your premises. The demarcation point is the line that marks the boundary between the telco equipment and the private network or telephone system. Normally, the LEC is responsible for all equipment on one side of the demarc, and the customer is responsible for all equipment on the other side of the demarc. The demarc is also called the minimum point of entry (MPOE) or the end user point of termination (EU-POT). The demarc is typically located on the bottom floor of a building, just inside the building. For residential service, the demarc is often a small box on the outside of the house. For business installations, the demarc is often identified by an orange plastic cover on the wiring component. Main Distribution Frame (MDF) The main distribution frame is the main wiring point for a building. It is usually located on the bottom floor or basement. The LEC typically installs the demarc to the MDF. Intermediate Distribution Frame (IDF) An intermediate distribution frame is a smaller wiring distribution point within a building. IDFs are typically located on each floor directly above the MDF, although additional IDFs can be added on each floor as necessary.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
