4.1 API Primitives
This chapter provides a detailed description of the primitives (requests and responses) that comprise the ISUP API and the events (indications and confirmations) received via the
ISUPRetrieveMessage
primitive. It also describes the parameters (information elements) supported for each request/event. Note that not all parameters are applicable to both ANSI and ITU-T (CCITT) networks.
