THEORY OF OPERATION
4.1 Monitor and Control
A sophisticated microcontroller performs the monitor and control functions of the
switch. The module, called the “Monitor and Control” (M&C), plugs into slot 5 of the
switch chassis (refer to Figure 4-1 for a drawing of the M&C, and Figure 1-3 for the
location in the chassis).
The M&C gathers status and provides extensive fault monitoring. The M&C monitors
the switch configuration and updates other modules within the switch, as required.
Switch configuration parameters are stored in battery-backed RAM to provide total
recovery after a power-down.
A local front panel interface and a remote communications interface provide user access
to all switch functions.
