MTP3 routes the message back to the origination SP. This local PSP is created automatically, not configured. Problems, comments, suggestions, corrections including broken links or something to add?

For m3ux information, see M3UA management function summary. Defined by RFC Automatically reroutes traffic in the case of failure or congestion. Please take the time from a busy life to ‘mail us’ at top of screenthe webmaster below or info-support at zytrax. Needs the SCCP services.

Maintains the availability status of all destinations through all routes. If multiple protocol variants network definitions or multiple upper layers must be supported on the same M3UA instance same boardan NSAP is required for each SIO value and protocol variant.

This interface is implemented with a set of messages that the application can pass to the M3UA layer on the TX communications processor.

You could, at no charge, upgrade to a W3C standards compliant browser such as Firefox. Interface to the higher and lower SS7 layers. Each user application might be assigned its own stream virtual connection.


SG is an SS7 node with a point code. Tutoriial for messages to be delivered in the order in which there were sent. Routes messages to their IP destinations. MTP3 routes from point code to point code. Does not need SCCP services, reducing the complexity of the node and thereby reducing cost.

M3UA layer

Both transport MTP3 messages. SUA can enhance the efficiency of the network and provides a means for simpler implementations. M3UA uses a flexible configuration capable of supporting a wide variety of network routing and addressing requirements. A standard IP layer.

There is a one-to-one relationship between a peer server and a routing key. For more information, see M3UA service function summary. Each IPSP must have its own point code. One address is designated as the primary address to receive data. The IPSPs do not require point codes. A single IP port number is used across the entire address list at an endpoint for a specific session. The SCTP user can specify at startup time the number of streams to be supported by the association.

A peer signaling process can be in an active or standby state. Each IP node does not require a point code. SG is tutoial an SS7 node and has no point code. In case of network failures, use of more than one address can allow re-routing of packets, and also provide an alternate path for retransmissions.

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 ,3ua. Routing keys are defined using c ombinations of the following parameters: SCTP’s multi-streaming allows data to be delivered in multiple, independent streams, so that if there is data loss in one stream, delivery will not be affected for the other streams. For more information, see M3UA message handling.


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. Each peer server serves a specific routing key. A device that converts from one protocol to another. SG can have upper SS7 layers, e.

You will have a warm inner glow for the rest of the day.

Tech Stuff – SIGTRAN (SS7 over IP)

Cannot support ISUP services. Allows for multiple virtual connections on the same physical line. View the status of the SCTP association by which the remote peer signaling process is reachable. End-points exchange lists of addresses during initiation of the connection. The primitives are described in Q. F or more information, see M3UA management function summary.

Each NSAP is associated with a service indicator field and protocol variant combination. Each M3UA instance can support up to associations.
