IDF – DMarc – Head End
Intermediate Distribution Frame (IDF)
An Intermediate Distribution Frame for telephone exchange offices may also contain termination equipment for a variety of components. For LANs and WANs, IDFs may also contain: Components for backup systems such as hard drives, RAID arrays, CD-ROM drives, hubs, routers & switches for networking, and connections for fiber optic, coaxial and other cables.
An MDF may enter the first floor of a building from a phone company or other buildings then the IDF would run through the walls to each successive floor where connections for lines to individual workstations, personal computers, etc. are located.
Contractors are cautioned not to use the IDF rack for grounding other equipment, such as welding or test equipment. Possible voltage and current spikes may easily damage sensitive electronic equipment as the IDF may not have sufficient grounding to convey excess voltages to earth.
Demarcation Point (Dmarc)
Demarcation points differ depending on the building type and service level. They include a junction block where telephone extensions join to connect to networks. The junction block includes a lightning arrestor. Demarcation points have user-accessible RJ-11 jacks connected to the telephone network, and small loops of telephone cords connecting to jacks by modular connectors. In the United States, the demarcation point is a device defined by Federal Communications Commission rules designed to provide for the safe connection of third-party telephone customer premises equipment and wiring to public switched telephone networks.
