# 6 SCCP/TCAP

Purpose

The Signaling Connection Control Part (SCCP) and Transaction Capabilities Application Part (TCAP) are parts of the SS7 signaling protocol.

This chapter describes the implementation of the SCCP/TCAP feature in the CSP software.

Information is also provided about configuring SCCP/TCAP options for customization, parameters, segmentation, services, and applications supported.

For information about implementing a TCAP direct host connection on the CSP, see SCCP/TCAP in the CSP Architecture .

SCCP. The signaling connection and control part of the SS7 signaling protocol. For example, performs Global Title Translations (GTT), Subsystem Management.
TCAP. The transaction capabilities application part of the SS7 protocol. It is the top layer of the SS7 stack, equivalent to Layer 7 of the OSI model.
