Stack Dynamics SS7 Stack - Specification SCCP The primary function of SCCP (Signalling Connection Control Part) is to provide a means for the transfer of messages between any two signalling points in the same or different (but interconnected) SS7 networks. SCCP provides the following extra facilities over MTP: An address may be specified as a global title, which may consist of a national or international telephone number, or a number from any other specified scheme. An address may be specified as a destination point code (DPC) plus subsystem number where subsystem number is an 8-bit number. (MTP can only address a DPC plus a 4-bit user number). SCCP may segment/recombine messages which would be otherwise not possible to transfer in one MTP message. Stack Dynamics SCCP will implement a subset of the full SCCP. In particular only the connectionless services will be implemented. Stack Dynamics SCCP Features Q.711-Q714 National and international networks Class 0 (basic connectionless) Class 1 (sequenced connectionless) Global title translation Remote subsystem status management Message segmentation Availability Not yet available - in development.   For further information on this product please contact: Colin Chambers colinchambers@stackdynamics.com +44 (28) 9752 8617
