Descriptions

SCCP (Signaling Connection Control Point) provides additional routing capabilities via Sub-System Numbers (SSNs). It also offers the capability of routing based on dialed digits or global title translation. UltraWAVE SCCP module supports ITU-T, ETSI, ANSI, Chinese variants of the protocol, enabling applications to be widely deployed.

The UltraWAVE SCCP module provides the means to:

•Route TCAP messages from end-to-end

•Translate from Global Title numbers to point code and subsystem numbers

•Establish and release connections

SCCP provides routing services for TCAP on an end-to-end basis, which supplements the point-to-point routing of MTP. In addition, SCCP translates Global Titles to point codes and subsystem numbers, simplifying routing table maintenance within a network.

| Local Node

Local Node provides subsystem numbers to allow messages to be addressed to specific applications.

| GTT

Global Title Translation is the SS7 equivalent to IP routing. Translation examines the destination address (e.g. the number being called) and deciding how to identify it over the telephone network. This process can include global title analysis, which is the act of looking up the number and finding a result address, and global title modification.

| Network Code

The Network Code table contains the information necessary to identify the intended endpoint for the telephone call.

•CC: The Country Code is a one, two, or three digits number used to identify the country's network.

•NDC: The National Destination Code defines the national calling area or national network to which the subscriber belongs.

•MCC: The Mobile Country Code is a three digit number uniquely identifying a given country. It is utilized within the IMSI (International Mobile Subscriber Identity) and LAI (Location Area Identity).

•MNC: The Mobile Network Code is either a two or three digit number used to uniquely identify a given network from within a specified country. The MNC is used as part of the IMSI and LAI.

•International Prefix: It is a digit or combination of digits used by a subscriber when making an international call. The international prefix is used to indicate that the following digits represent an international number and should be routed to an international gateway.

•National Prefix: It is a digit or combination of digits used by a subscriber when calling a national destination (within the country) other than that of the local area network.
