 DSI SS7G41 Signaling Server – SIU Mode Release Notes 

Release 1.1.1 

43 

Release 1.1.1 

1

 

Overview 

This release is a feature release which enhances SCCP support and allows 
SS7LD boards to be used in ‘drop and insert’ mode. It also includes changes 
and corrections as detailed below. 

SCCP Global Title Load Share Tables provide the ability for a Global Title 
Translation to result in a list of Destination Point Codes to increase system 
resilience in the event of a DPC failure. 

‘Drop and Insert’ functionality allows a combined media and signaling E1/T1 
to be terminated on the SS7G41 with the signaling processed by the SS7G41 
and the media passed on through another E1/T1 interface to the media 
processor. 

This release is fully backwards compatible with the previous release. 

1.1

 

Applicability 

This release is applicable for users who require the newly introduced 
capabilities or corrections.

New Functionality 

2.1

 

Global Title Load Share Tables 

Global Title Load Share Tables support the distribution of messages for a 
configured Global Title translation rule across a number of Destination point 
codes. A load share table holds a number of Point Codes across which 
messages will be distributed. 

A new configuration command

, SCCP_LOAD_SHARE_TABLE, 

allow users to 

establish a Load Share Table and select run-time options. 

A second command, 

SCCP_LOAD_SHARE_DPC

 should be used to associate 

a destination point code with the Load Share Table. The command should be 
used multiple times, each time adding a single point code to the Load Share 
Table. 

A Load share table can be associated with a GTT by configuring it as the point 
code in the 

SCCP_GTT_ADDRESS 

command.

 

A new command, 

CNLTP

, displays current Load Share Tables and the 

command 

CNLDP

, shows the assignment of Destination Point Codes to a 

Load Share Table.  

The command syntax is specified in the 

SS7G41 Operator’s Manual

. 

2.2

 

Drop and Insert 

‘Drop and Insert’ functionality allows a combined media and signaling E1/T1 
to be terminated on the SS7G41 with the signaling processed by the SS7G41 
and the media passed on through another E1/T1 interface to the media 
processor.
