Signaling Connection Control Part (SCCP)

The main function of the signaling connection control part (SCCP) of the Signaling System Number 7 (Q.700 88) is the catering for both connectionless as well as connection-oriented network services to transfer circuit related and non-circuit related signaling information and other types of information between exchanges and specialized centers (particularly for management and maintenance purposes) in the telecommunication networks via a Signaling System No. 7 (SS7) network. One of its overall objectives is to provide the means for establishing the logical signaling connections within the SS7 network and for transferring the signaling data units with the use of the logical signaling connections.
