1.7 Theory of Operation
The reciter receives RF signals from its RF input and sends RF from its RF
output 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 1.4).
A system control bus interconnects the modules and carries alarm and
control signaling between the reciter and the other modules.
The Ethernet interface carries voice over IP and also allows maintainer
access via a web browser.
