Release Notes for *.dc6 code files - V1.10

1 Overview

This is the first full release of the code file for the Dialogic

DSI SS7MDL4

Network Interface Board since V1.08. It contains an important correction to

prevent the board spontaneously shutting down and new functionality to

provide additional control over LIU clock recovery.

The release is fully backwards compatible with the previous release.

1.1 Applicability

All users are advised to upgrade to this release as it includes enhancements

to prevent occasional board shutdown issues.

To benefit from the enhancements contained within, the code file must be

used in conjunction with either the Dialogic

DSI SS7 Development Package

for Linux 6.2.0 (or later) or the Dialogic

DSI SS7 Development Package for

Solaris 5.0.2 (or later).

1.2 Resolved Customer Issues

Updates to resolve the following customer issues are included in this release:

IPY00091590.

2 New Functionality

2.1 LIU Clock Recovery

This release provides support to optionally exclude individual LIUs from being

considered for clock recovery.

When using s7_mgt, an LIU can be excluded as a source of clock recovery by

setting bit 0 in the <options> parameter in the LIU_CONFIG command.

When using message-based configuration set bit 0 in the ‘clk_opt’ field of the

LIU_MSG_CONFIG message. The ‘clk_opt’ field is a 2 octet parameter

commencing at offset 19.

3 Other Changes

3.1 Board Shutdown (IPY00091590)

Under certain circumstances, the board could spontaneously shutdown,

potentially causing operating system ‘panic’ or ‘confusion’. This code file when

used in conjunction with drivers from the Development Packages listed above

corrects this issue.
