Gives an overview and usage requirements for the Synchronous Optical Network (SONET) Transport Information Model listing object class definitions given by other Bellcore GRs and standards documents. Extra information is given to aid developers in understanding, implementing and using the information model. A companion paper GR 1042 IMD gives definition of object classes using GDMO templates and ASN.1 supporting products.
