Which MSSR terminal is used for maintenance?

• A. Control and Monitoring System (CMS)
• B. Plot Processor
• C. Transmitter Interface
• D. Receiver Interface

Answer: (A)

The maintenance tasks are handled by the Control and Monitoring System. This terminal is the technician’s hub for MSSR, providing system-wide health status, alarms, diagnostics, calibration tools, software updates, and configuration control. It’s designed for monitoring, troubleshooting, and keeping the radar system running, not for real-time signal processing.

The other components serve operational roles in the signal path: the Plot Processor is for displaying tracked data and radar plots, while the Transmitter Interface and Receiver Interface manage the RF hardware interfaces. These aren’t intended as maintenance consoles, so the Control and Monitoring System is the correct maintenance terminal.
