The microprocessor test and control units respond to commands to configure and perform various modem tests, operate autonomously to monitor various alarm conditions, and format status reports and alarm maydays for transmission back to the central processor. The system is capable of performing a wide variety of testing, monitoring and network control functions for a very large network of modems.
