Release 1.2.3
1
Overview
This release is a feature release which includes two significant new features:
Sigtran Gateway Capability and Message Router Functionality. Together these
combine to offer flexible extensions to existing SIU functionality and allow the
SS7G41 to be used in an autonomous mode without necessarily requiring an
SIU host or user application.
The release also increases the number of M3UA routes supported to 4096 and
includes other changes and corrections as detailed below.
This is the first Generally Available release since Release 1.1.1, it is fully
backwards compatible with that release.
1.1

The following additional User Documentation describes in detail the new
Sigtran Gateway Capability and Message Router Functionality:

New Functionality
2.1
Sigtran Gateway Capability
This release adds the ability for the Signaling Server to operate as an M3UA
Sigtran Gateway. The SS7G41 adds support for the Sigtran Nodal Inter-
working Function (NIF) allowing it to appear as a Signaling Gateway and
connect using M3UA to Application Servers. Operating as a Sigtran Gateway
the SS7G41 can then provide connectivity to TDM networks or to downstream
nodes using Sigtran M3UA or M2PA.
When operating as a Sigtran Gateway the SS7G41 can be used as a
replacement for SS7G2x and SS7G3x Signaling Servers operating in SGW
mode. Users should note that there are differences in the way in which the
products are configured (the SS7G41 uses a text based configuration file
(config.txt) for all protocol configuration commands whereas the
SS7G2x/SS7G3x products in SGW mode previously used interactive
configuration commands) but the same underlying functionality is available.
In addition there are new capabilities offered by the Message Routing
Functionality which allow the user to route messages based on parameters in
the MTP routing label.
