3.1 Monitor and Control
The modem uses a sophisticated microcontroller module to perform the M&C functions
of the modem (refer to Figure 3-1).
The M&C monitors the modem, and provides configuration updates to other modules
within the modem when necessary.
Modem configuration parameters are maintained in battery-backed RAM, which provides
for total recovery after a power-down situation.
Extensive fault monitoring and status gathering are provided.
All modem functions are accessible through a local front panel interface and a remote
communications interface.
