Release Notes for V5.11

1 Overview

This is a maintenance release including several small changes and

enhancements including config.txt configuration of SCCP and TCAP in dual

chassis deployments and increased message-length support for SCTP. Full

details of all the changes are detailed below.

This is the first full release since V5.09 it is fully backwards compatible with

the previous release.

2 New Functionality

2.1 config.txt configuration of dual chassis SCCP and

TCAP

The ability to distribute the protocol stack over two separate chassis allows

users to realise systems that appear to the network as a single point code

whilst achieving fault tolerance in the event of a chassis failing.

See the Application Note: Enabling Dual Chassis Fault Tolerance with

Dialogic

Signaling Boards for a description of how such a configuration can

be used.

This release adds the ability to configure SCCP and TCAP in such

configurations by extending the SCCP_CONFIG and TCAP_CONFIG

commands. The full syntax of these commands is described in the SS7HD

Programmer’s Manual. The modifications to these commands are detailed

below:

SCCP_CONFIG <local_spc> <ssf> <options>

[<management_options> [<partner_id> <instance>]]

<partner_id> specifies the module_id of the partner SCCP module.

<instance> [range 0 - 15] which specifies the instance of SCCP

running on this system.

Note: In order to use the <partner_id> and <instance> parameters the user

must also provide the <management_options> parameter.

TCAP_CONFIG <base_ogdlg_id> <nog_dialogues> <base_icdlg_id>

<nic_dialogues> <options> <dlg_hunt>

[ [<addr_format>] <partner_id> <tcap_inst> ]

The new parameters <partner_id> and <tcap_inst> are used as follows:

<partner_id> specifies the module_id of the partner TCAP module.

<tcap_inst> [range 0 - 15] which specifies the instance of TCAP

running on this system.
