This read-only object reports the minor version of an SCT file, which the MIB says is incremented by the manager whenever the contents of one of the SCT's tables change, since the number and structure of those tables depend on the service module card type. An administrator can use this version number to confirm which revision of a Service Class Template is currently loaded on a given card. For example, if two cards of the same type report different minor version numbers for their SCT, an administrator would know they are running different table content versions and may need to be synchronized.
