The reciter receives RF signals from its RF input (antenna), and outputs this
to the PA, along with a PA key signal. The reciter also receives signals
from, and sends signals to, the system interface, the Ethernet interface, and
the front panel (see Figure
A system control bus interconnects the modules and carries alarm and
control signaling between the reciter and the other modules (refer to
"Intermodule Communications" on page 29
The Ethernet interface carries VoIP and also allows maintainer access via
a web browser.
