A method for making an apparatus for disambiguating telemetry sent by exception over a multi-path, multi-tier communications network having a plurality of telemetry source nodes producing telemetry data elements, a plurality of linked relay nodes, and one destination node, each telemetry source node connected to at least one relay node, wherein each node originates uniquely identifiable periodically changing counter data over said network, the method comprising the steps of obtaining a network diagram of said multi-path, multi-tier communications network, organizing data describing said network diagram, wherein said data describing said network diagram includes data relating to said counter data, and autocoding said data describing said network diagram to produce a telemetry disambiguating computer program. An apparatus and a program product are also provided.
