Each user application might be assigned its own stream virtual connection. SG’s single function is to relay MTP3 messages. End-points exchange lists of addresses during initiation of the connection.

SCTP’s multi-streaming sigttran 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.

Each IP node does not require a point code.

Tech Stuff – SIGTRAN (SS7 over IP)

If you are happy it’s OK – but your browser is giving a less than optimal experience on our site. Each IP node is required to have a point code and sittran IP address.


Cannot support ISUP services. Needs the SCCP services. Problems, comments, suggestions, corrections including broken links or something to add?


SG is not an SS7 node and has no point code. One address is designated as the primary address to receive data.

A single IP port number is used across the entire address list at an endpoint for a specific session. Allows for messages to be delivered in the order in which there were sent. SUA can enhance the efficiency of the network and provides a means for simpler implementations.

SG can have upper SS7 layers, e. SCTP uses periodic heart-beat messages to confirm the status of each end point.

MTP3 routes the message back to the origination SP. A standard IP layer. It is a ‘glue’ layer introductiob its functionality is not defined by the standards.

A device that converts from one protocol to another. Messages are handled from point code to point code. Each IPSP must have its own point code. Allows for multiple virtual connections on the same physical line.

You will have a warm inner glow for the rest of the day. Legal and Privacy site by zytrax web-master at zytrax Page modified: The IPSPs do not require point codes. Please take the time from a busy life to ‘mail us’ at top of screenthe webmaster below or info-support at zytrax. MTP3 routes from point code to point code. Both transport MTP3 messages.


The whole IP network is represented by a single point code that addresses the MGC at the network edge. The primitives are described in Q.

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. SG is iintroduction SS7 node with a point code. Does not need SCCP services, reducing the complexity of the node and thereby reducing cost. Defined by RFC T could, at no charge, upgrade to a W3C standards compliant browser such as Firefox.

The SCTP user can specify at startup time the number of streams to be supported by the association.
