ABSTRACT:
A system for diagnosing and controlling operation of a plurality of modems, some located at a central site and others at various remote sites. A processor located at the central site selectively addresses microprocessor test and control units at each modem over a secondary channel. 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.
