  1. BASIC TELECOMMUNICATIONS Structured media enclosure (distribution device)

  2. BASIC TELECOMMUNICATIONS • A structured media center (distribution device) provides a central location for all home and MDUs (multi dwelling units) network cabling to interface with the public utility services to include voice, data, and videoand provides a central location to also incorporate security, CCTV, audio and home automation.

  3. BASIC TELECOMMUNICATIONS • The structured media panels are designed in various sizes to accommodate all or some of the many services a customer may want to incorporate into their home and it also provides the means to add a power outlet • These distribution devices are covered by the TIA/EIA 570 standard (light commercial and residential wiring)

  4. BASIC TELECOMMUNICATIONS • Structured media enclosures are designed for either surface mount or recessed mounting and provide multiple knock outs similar to an electrical panel box • As you can see here they fit perfectly into the studs

  5. BASIC TELECOMMUNICATIONS • The distribution devices can be purchased with a hinged door panel or completely removable panel and can also be configured with a lock set • The bottom of the panel has a specific rectangular knock out to accommodate a single gang electrical outlet Knock outs

  6. BASIC TELECOMMUNICATIONS • In most homes the distribution device will be located in the basement where the public utility services enter the home • In MDUs the enclosures are located in closets or laundry rooms

  7. BASIC TELECOMMUNICATIONS • All new condominiums and apartment buildings (MDU) are now using the structured media enclosure for all of the low voltage systems • Many of these enclosures also have empty conduits (micro duct) for future growth in anticipation of bringing fiber optics directly into the unit

  8. BASIC TELECOMMUNICATIONS • Structured media panels are designed to house network devices such as routers and/or switches, voice modules and CATV splitters • This allows direct patching from the communications infrastructure directly to POTS lines, internet access or CATV signals that can distributed throughout the premises

  9. BASIC TELECOMMUNICATIONS • When working in a residential environment the technician will have to bore holes in wooden studs to provide pathways to the distribution device • The International residential code (IRC) as well as NEC article 300.4A1 dictates how holes are to be bored in wood members, joist and rafters

  10. BASIC TELECOMMUNICATIONS • This will require the use of a right angle drill to properly bore straight holes that will conform to NEC and IRC statues

  11. BASIC TELECOMMUNICATIONS • So far we have learned that POTS is 4 conductor, category 1 cable which is still prevalent in many homes today What do you think is the minimum Category of UTP cabling allowed for installation in new residential dwellings?

  12. BASIC TELECOMMUNICATIONS • The FCC requires a minimum of CAT 3, 4 pair cable to be installed in all new residential dwellings • Most residential installs today consist of one CAT 5e and one RG-6 coax cable at each location and run directly to the distribution device (star network) • TIA/EIA 570 grade 1 cable calls for one CAT 5e and one RG-6 at each location with one outlet in each room

  13. BASIC TELECOMMUNICATIONS • TIA/EIA 570 grade 2 cabling calls for two CAT 5e and two RG-6 cables at each location and 1 outlet for every eight feet of wall space

  14. BASIC TELECOMMUNICATIONS Here is a home network design diagram with the distribution device interfaced to the D-marc
