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.

ABUS-VC2 Volume Control Power Module for the A-Bus System (CAT-5 Punchdown Connection)


ABUS-VC2 Volume Control Power Module for the A-Bus System (CAT-5 Punchdown Connection)

Atlas ABUS-VC2 Volume Control Power Module for the A-Bus System

ABUS is a revolutionary new technology created to simply and affordability distribute music in commercial and home applications. ABUS works with inexpensive 8-conductor (CAT 5) wire to distribute audio, infrared, status and system power to the ABUS in-wall controller/amplifier.

The MTX A-BUS VC2 volume control power module incorporates stereo amplifiers with individual level adjustments (left and right) that can power a pair of 4 or 8 Ohm speakers in each zone.

Only one category 5 (CAT-5) cable is needed to connect the hub and the power module making install quick and easy. Speaker cable is then run from the power module to the speakers.

The MTX VC2 IR-equipped modules relay 38kHz and 56kHz codes to the source components for input track/channel selection, etc. It also includes infrared talk-back and status indication. An LED indicator signifies when the A-BUS system is on (see Power/Status below) and it flashes to signify an infrared command has been received.

The volume level on the MTX VC2 A-BUS module can also be operated by the supplied remote control handset. Three colors of Decora style wall-plates, inserts, and buttons are also included (white, ivory, and bone).

  • Left And Right Gain Controls
