This paper presents an approach for a generic fault isolation (FI) concept for telecommunication systems in the access network area. Based on a distributed processor architecture, a universal software structure for a FI unit is proposed. It is able to isolate faults, field replaceable units and is easily portable to different hardware platforms. The reusability of the FI unit is achieved by separating the software into generic control functionality and fully hardware‐dependent software parts, i.e. user configurable tables and hardware‐dependent control routines. The implementation of the concept is discussed in a ‘fiber to the building’‐system which has already entered into mass‐production. © 1997 John Wiley & Sons, Ltd.
