Formal title: MDD Error - MTC LLFC SSC Combinations Screen
The drop-down list within the Maintain Valid MTC LLFC SSC Combinations screen produces a display of valid LLFC/SSC Combinations for selection and standard operational procedures involve the system operator selecting a valid combination using this drop down list. Under test conditions it has been demonstrated that it is possible to input an invalid LLFC/SSC combination by circumventing the standard operational procedures. It is possible to enter an MS Specific LLFC of ‘A’ where the SSC Type is ‘E’ and an MS Specific LLFC of ‘C’ where the SSC Type is ‘I’, both of which are invalid combinations.
