ABSTRACT:
Telecommunications equipment used in outdoor environments are subjected to harsh electrical conditions. Circuits which utilize sequential components, such as microprocessors, can therefore become confused due to extraneous power surges which may occur in the harsh conditions existing around the equipment. Furthermore, maintenance of the equipment has become much more automated, often leaving the equipment unattended for extended periods of time. In accordance with the invention, a circuit which automatically and reliably recognizes the failure conditions in the microprocessor, and automatically forces the microprocessor to recover is described.
