3.1.6 Monitor & Control (M&C) Subsystem
Also contained on the BB Card is the M&C Subsystem. The M&C contains a high-performance
microprocessor and is responsible for overall command and control of modem functions. The
M&C is constantly monitoring all subsystems of the modem by performing a periodic poll routine
and configures the modem by responding to commands input to the system. During each poll
cycle, the status of each of the subsystems is collected and reported to each of the external ports
and Front Panel. Performance statistics such as Eb/No, buffer fill %, etc. are compiled. If faults
are detected, the M&C will take appropriate actions to minimize the effect of such faults on the
system (refer to the Fault Matrices in Section 6).
The M&C subsystem contains the following features:

3.1.6.1 Terminal

This port is dedicated to the Terminal Program. With this program, all features of the modem
may be controlled and monitored by any common terminal connected to the Terminal Port.
