<p>There is provided a system and method for tracking utilization data for an electronic device, the electronic device having a non-volatile data storage component associated therewith for retaining the utilization data. In an embodiment, the method comprises the steps of: a) after passage of a utilization interval, reading a first utilization data value for the electronic device stored in the non-volatile data storage component; b) incrementing said read value; and c) storing said incremented value into the non-volatile data storage component. In an embodiment, the electronic device is a circuit card operating in a communication switch, and the utilization data value is a time value indicating cumulative time of operation of the circuit card in the communication switch. <IMAGE></p> |
