Audio Bridge Terminal
Multiplexed Audio Outputs
Multiplexed Audio Outputs
The multiplexed audio outputs are formatted to be compatible with the STDI audio input
connections on the KXI-16 series of cards.
The Serial Digital Transport Interface (SDTI) uses the Serial Digital Interface (SDI) developed
to transport digital video signals as a carrier for other data types. It requires that the
transmitter and receiver have the same codec.
Ethernet/Power
The power for the ABT arrives on an RJ-45 connector, and shares this connector with an
Ethernet interface. The ABT conforms to the IEEE 802.3af standard for powered devices
Two kinds of power sources are supported:
• midspan power source injector into an existing Ethernet network,
• power sourcing Ethernet switch.
Full redundancy is obtained with both supplies present at the same time.
Indicators
The ACTIVITY indicator is located on the right-hand side of the rear panel. This LED reports
the status of the Ethernet connection as follows:
Two LEDs are visible on the front panel, one for each power supply. When lit, they both
indicate the same status:
When the ABT is powered up, all three LEDs will be orange until the boot sequence is
terminated. This is a visual indicator that the LEDs are functioning properly.
