The Teradata PT operator interface is a bidirectional call-level interface that provides the intercommunication between the Teradata PT processor and the operators.

All functional communication within the Teradata PT infrastructure is through the Teradata PT operator interface—there is no direct communication between operators, or between operators and the Teradata PT processor.

The interface is defined by the following user-provided and service functions.
