The primitives are described in Q. Both transport MTP3 messages. For more information, see M3UA service function summary. Defined by RFC It performs these primary tasks:.

Tech Stuff – SIGTRAN (SS7 over IP)

View the status of the SCTP association by which the remote peer signaling process is reachable. The transport addresses used by the endpoints in the association uniquely identify that association.

Each M3UA instance can support up to associations. One address is designated as the primary address to receive data.

Each IP node does not require a point code. If multiple protocol variants network definitions or m3uaa upper layers must be supported on the same M3UA instance same boardan NSAP is required for each SIO value and protocol variant. Cannot support ISUP services. For more information, see M3UA message handling. Allows for multiple virtual connections on the same physical line. In case of network failures, use of more than one address can allow re-routing of m3ux, and also provide an alternate path for retransmissions.


Dialogic NaturalAccess SIGTRAN Stack Developer’s Reference Manual (): M3UA layer

The IPSPs do not require point codes. Each user application might be assigned its own stream virtual connection. Peer servers can be local or remote. A standard IP layer.

For more information, see M3UA management function summary. Routes messages to their IP destinations. The whole IP network is represented by a single point code that addresses the MGC at the network edge. SCTP uses periodic heart-beat messages to confirm the status of each end point. A peer server PS is a logical entity on the IP network, such as a virtual switch or a database element, that is served by one or more peer signaling processes PSPs.

M3UA uses mu3a flexible configuration capable of supporting a wide variety of network routing and addressing requirements. A single IP port number is used across the entire address list at an endpoint for a specific session. Routing keys are defined using c ombinations of the following parameters: Messages are handled from point code to point code.

M3UA layer

SCTP’s multi-streaming allows data to be delivered in multiple, independent streams, so that if there is data loss in one tutrial, delivery will not be affected for the other streams. This local PSP is created automatically, not configured. Allows for messages to be delivered in the order in which there were sent.

SG’s single function is to relay MTP3 messages. It is a ‘glue’ layer and its functionality is not defined by m3uz standards. If you are happy it’s OK – but your browser is giving a less than optimal experience on our site. Each NSAP is associated with a service indicator field and protocol variant combination.


F or more information, see M3UA management function summary. Problems, comments, suggestions, corrections including broken links or something to add? SUA can enhance the efficiency of the network and provides a means for simpler implementations. Each IPSP must have its own point code. You will have a warm inner glow for tuotrial rest of the day. SG is an SS7 node with a point code. A routing key defines the range of signaling traffic m3uz be handled by a particular peer server.

The SCTP user can specify at startup time the number of streams to be supported by the association. SG can have upper SS7 layers, e. There is a one-to-one relationship between a peer server and a routing key. This interface is implemented with a set of messages that the application can pass to the M3UA layer on the TX communications processor. A peer signaling process can be in an active or standby state. Each j3ua server serves a specific routing key. End-points exchange lists of addresses during initiation of the connection.
