Please take the time from a busy life to ‘mail us’ at top of screenthe webmaster below or info-support at zytrax. 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 sigtram streams.


SG is an SS7 node with a point code. You will have a warm inner glow for the rest of the day. Each IPSP must have its own point code. Cannot support ISUP services.

Allows for messages to be delivered in the order in which there were sent. 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.


Needs the SCCP services. If you are happy it’s OK – but your browser is giving a less than optimal experience on our site.

A single IP port number is used across the entire address list at an endpoint for a specific session.

Tech Stuff – SIGTRAN (SS7 over IP)

A device that converts from one protocol to another. SG’s single function is to relay MTP3 messages. SG is not an SS7 node and has no point code.

Does not need SCCP services, reducing siggran complexity of the node and thereby reducing cost. The whole IP network is represented by a single point code that addresses the MGC at the network edge. SUA can enhance the efficiency of the network and provides a means for simpler implementations. Problems, comments, suggestions, corrections including broken links or something to add?

Each IP node is required to have a point code and an Introfuction address. The primitives are described in Q.

SCTP uses periodic heart-beat messages to confirm the status of each end point. MTP3 routes from point code to point code. Both transport Intrroduction messages.


Each sigtrna application might be assigned its own stream virtual connection. You could, at no charge, upgrade to a W3C standards compliant browser such as Firefox. The IPSPs do not require point codes.

It is a ‘glue’ layer and its functionality is not defined by the standards. One address is designated as the primary address to receive data. Messages are handled from point code to point code.

SG can have upper SS7 layers, e. Allows for multiple virtual connections on the same physical line. A standard IP layer. Legal and Privacy site by zytrax web-master at zytrax Page modified: Each IP node does not require a point code. Defined by RFC The SCTP user can specify at startup time the number of streams to be supported by the association.

MTP3 routes the message back to the origination SP. End-points exchange lists of addresses during initiation of the connection.
