Overview
This section lists the SCCP primitives supported by the SCCP/TCAP feature. Primitives are sent to and received from the CSP in the PPL Event Request and PPL Event Indication messages in the ICB:
• SS7 SCCP Parameters (0x20).
Important! SCCP/TCAP primitives should not be confused with Dialogic PPL primitives. SCCP Components should not be confused with Dialogic PPL components. See the PPL Information for PPL event values and the API Reference ICB formats.
The required ICBs with mandatory (M) and optional (O) parameters are shown with each primitive. See SCCP/TCAP Parameter Information for the data required for each parameter.
The SCCP User Interface is responsible for message validation and format conversion. The following events are used to send and receive primitives for the PPL component, SCCP SUSI (0x67).
