1.  Performance Criteria:
    The same procedures and criteria will be used for the ported deliverables
    as for other Intelecable supported platforms.  CableData uses performance
    benchmarks as capacity and reliability guidelines for system performance. 
    Capacity involves transaction rates, and reliability relates to the
    availability of the Intelecable software without interruption.  The
    guidelines are used as a guide for determining whether or not analysis and
    corrective action are indicated.

2.  Test Procedures:
    CableData's automated performance test lab will be used for all feature and
    performance regression testing.

3.  Error Definitions:
