摘要： A method for reducing the occurrence of false ground fault detections in a central office terminal is provided. The method includes generating a no-fault signal when no ground current is detected, delaying generation of a fault signal when ground current is detected at least for the duration of an expected pulse in AC induced signal, and when the ground current persists for a sufficient period, generating a signal indicating a fault condition.

摘要： In one embodiment, a power supply comprises a flyback transformer comprising a primary winding and at least two secondary windings. An output voltage is developed across a first one of the secondary windings. The power supply comprises a transistor coupled to the first one of the secondary windings.

摘要： A bit error rate or other performance characteristic of a communication link is monitored using a state machine. The state machine includes at least three states — for example, a NO ALARM state, an ALARM DETECTION state, and an ALARM state. A sliding window is used to determine when to transition from the ALARM DETECTION state to the NO ALARM state or the ALARM state. A sliding window is also used to determine when to transition from an ALARM state to a NO ALARM state. A respective sum is calculated as a function of the sliding window for use in making such determinations.
