US 7,248,831 B1 · Remote system status monitoring and software recovery on wireless bridges

Abstract

Disclosed are methods and apparatus for an inside bridge component to monitor the status of an outside unit (ODU) of a wireless bridge and to then handle a faulty ODU and/or faulty cable continuity with the ODU. A mechanism is provided for determining whether the inside component is coupled to a valid ODU prior to the inside component powering up the ODU. Mechanisms are also provided for the inside component to initiate a configuration or software recovery in the ODU. After a valid ODU is powered up, mechanisms are also provided for monitoring the cable continuity between the inside component and the ODU and removing the power from the ODU when the cable continuity is out of specification.
