TIA568 Wiring Standards

How to decide which wiring pattern to use:

1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.

If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

Distribute Audio and Video signals anywhere in the home using Category 5 Cable and Leviton's Decora Media System (DMS). Send music, VCR, DVD, cable TV, satellite and security camera signals through up to 1,000 feet (300 meters) of cable with no audio or video distortion, and better performance than the more expensive, specialized "designer" cables.

DMS is comprised of: a Send Unit for transmitting audio/video signals, a Receive Unit for receiving signals, and a Media Hub for whole house distribution.

The DMS utilizes advanced active electronics to operate with several different topologies: a computer networking scheme, with peripheral components sending and receiving critical information via Send and Receive units and the centralized data-communications hub; a Hub-to-Receive model, where information is sent to the hub–and from the hub to remote Receive units; and a Point-to-Point model, where Send and Receive units are linked directly together.

All three units run on 12VDC and can be powered independently or through the Media Hub.

FEATURES

  • Panel can be attached vertically or horizontally in SMC Enclosures.
  • "Daisy-chain" hub units to distribute audio/video signals to over 20 locations
  • Send and Receive units are equipped with RJ-45 jacks and 110 punchdown blocks for maximum flexibility in installation.
  • RCA inputs for connectivity directly from A/V source
  • Use a simple, point-to-point configuration, or an advanced network hub-style configuration.
  • Units fit standard wall boxes and Decora wallplates.
  • Advanced circuitry with automatic equalization streams analog audio and video signals over long distances with less distortion.
  • Stereo audio input/output handles Dolby® ProLogic surround signals.
  • Send music, VCR, DVD, cable TV, satellite and security camera signals through Category 5 (or better) cable.
  • RJ-45 input from send unit or security camera
