                                2              partial record call reestablishment

Values 4, 5 and 20 are valid within a GPRS Call context only where the call did not terminate normally.  Where partial GPRS Calls are generated then only the last partial can contain a cause for termination where appropriate.

Values 3, 4 and 5 are valid within a MOC/MTC only where the call did not terminate normally.
