Problems solved by technology

An operational defect may be a design defect in hardware circuit or software element implemented on the circuit board.
As the register is often associated with the station in a database maintained on a server or a computer, the tracking information associated with the card remains with the station, which causes potential loss of information if the register at the station is lost.
There is typically little cost benefit in retrofitting a board with a manufacturing cost red

Abstract

The invention provides a system and a method of electronically tracking a history of engineering change orders (ECOs) associated with a manufactured device. The device has at least one electronic component thereon. The method comprises, generally, storing in an electronic storage device associated with the device, the history of ECOs and updating the history of ECOs when a new ECO is associated with the device to indicate whether the new ECO was implemented on the device. The system utilizes the method and has an electronic storage device associated with the device and a data element stored therein. The contents thereof indicate the history of ECOs for the device and allow modification thereto to indicate whether a new ECO was implemented thereon. An ECO history enables a determination to be made of compatibilities between hardware and software elements and between hardware and firmware elements.

Description

[0001] The invention relates to a system and method for tracking of engineering change orders (ECOs) relating to repairable elements of an electronic device, in particular a system and method for tracking ECOs of field replaceable units (FRUs), such as circuit cards, of a communication device connected to a communication network.BACKGROUND OF INVENTION[0002] It is common for an electronic device (which includes most types of communication devices) to utilize a series of circuit cards to provide aspects of the functionality of the device. Generally, a feature of a circuit card is that it can be removed and replaced from the electronic device when the circuit card fails or needs to be upgraded. In many devices, the circuit card may be replaced in the field, in situ. Accordingly, the circuit card is often referred to as a field replaceable unit (FRU).[0003] Circuit cards typically have hardware, software and firmware elements used in hardware circuits to provide their functionality. Th...
