5.2.1 Monitor and Control (M&C)
The Monitor & Control uses a microcontroller to control all operational parameters and
monitor system status. The system also reports modem configuration status and fault
status of the unit. A simple command set allows configuration, control, and retrieval of
status information.
A block diagram of the M&C is shown in Figure 5-1.
5.2.2 Theory of Operation
The M&C section is composed of the following subsections:
! Analog-to-Digital Converter (ADC)
