This application relates to monitoring of electronic devices (100) and in particular to methods and apparatus for the detection and recording of an electrical overstress applied to a connector (101, 102) of the device. The apparatus describes an integrated circuit integrated circuit (103, 105, 106a) of the host device having a first set of one or more circuit contacts (201, 203, 204, 205) for connection to a connector (101) of a host electronic device. The circuit has an electrical overstress monitor (106, 106a) for detecting and recording an electrical overstress comprising a voltage exceeding a predetermined parameter applied to at least one of said first set of circuit contacts. The electrical overstress monitor (106) may have an overvoltage detector (205) and may have a memory (206) for recording the occurrence of an overvoltage and/or a communication module (207) for communicating with other components of the host device in the event of an electrical overstress.

A power distributor for a communications system for controlling delivery of electrical power drawn over a plurality of electrical communications connections allocated to respective customer premises equipment, to provide electrical power to network components within a network is arranged to control collection of electrical power to be drawn from each connection in accordance with power requirements of services operated by or for its respective customer premises equipment, independent of the identities of the electrical connections used to deliver those services. In particular when electrical connections are not being used by their respective customers they may instead be used by a beam-forming system to support improved service to a customer associated with a different connection, and the additional electrical power to power the beam-former is drawn from the connection associated with the customer receiving the enhanced service.
