Planning the Residential Telecommunications Cabling System

Planning the Residential Telecommunications Cabling System
Planning should be made before the rough-in installation phase of the electrical wiring. An example of the design procedure is provided below:

1) Obtain building plans.

2)Select and mark the outlet locations on the building plan. Determine location of internal video sources. When planning outlet locations, consider the potential positioning of furniture.

3)Based on the selected Grade of service, choose types and number of Outlet Cables and Outlets for each outlet location.

4)Locate NIDs for each service provider line and mark them on the building plan.

5)Locate physical obstacles and EMI sources and mark them on the building plan.

6)Select location and define space requirements for the Distribution Device (including future expansions and upgrades). Mark the DD location on the building plan.

7)Select routes and pathways for Outlet Cables & ADO cables avoiding known obstacles and EMI sources. Mark the routes and pathways on the building plans.

8)Develop a clear labeling plan for cables and hardware.

9)Check that maximum distance from the NID to the outlets does not exceed 150 m (492 ft.).

10)Check that maximum distance from the DD to the outlets does not exceed 90 m (295 ft.).

11)Check that all requirements from the National Electrical Code (NEC) and applicable local codes for cabling, pathways and grounding are strictly observed.
