Various configuration examples of combinations of SS7 features in Yate. ; type=ss7-m2ua-gateway

*Both protocols represent a SIGTRAN SS7 layer 2 protocol *They have the same functionality, to transport SS7 layer 3 messages over IP network.

These cards provide voice channels and also support for signaling SS7 MTP2 (or ISDN Q.921).<br>

SCCP represents a layer 4 protocol from SS7 signaling stack. It runs over a SS7 layer 3 protocol like MTP3 or M3UA.

...t it does not process messages, instead it transfers the messages to other SS7 nodes that need to do the processing.<br/> Given this fact, a STP needs to be connected to multiple SS7 nodes, usually other STPs and possible one or more SEPs.<br/>

Introductory information on SS7 is available for free on the Internet from various sources. * [http://en.wikipedia.org/wiki/Signaling_System_7 SS7 page on Wikipedia]

Bellow is a typical example of a SS7 network. The schema focuses on the SEP 1 node and presents the elements fro ::A single connection between two SS7 signaling points, it is defined by the Point Codes of the ends of the link

In Yate the following SS7 components are implemented: * '''M2PA''' (SIGTRAN) to connect over SCTP/IP to another SS7 node.

...DPC, SLS and CIC of the message cannot be changed as that will break basic SS7 and ISUP assumptions.

*Handle the SS7 protocol (management, maintenance, routing). ...ing SS7 packets and transmit them. Find a destination service for incoming SS7 packets.

To connect to another SS7 network you will need to configure some parameters so the two sides speak t ** Type of SS7 network at MTP level: ITU, ANSI, etc. (determines the Point Code type)
