Provisioning the Cisco HSI

Introduction

This chapter describes the data that must be provisioned for the Cisco H.323 Signaling Interface (HSI). The data is divided into two areas: system configuration and H.323 stack data. This chapter contains the following sections:

•Cisco HSI Configuration, page 3-1

•H.323 Stack Configuration, page 3-10

•HSI Feature Configuration, page 3-22

Cisco HSI Configuration

All configuration data is contained within configuration files. Cisco HSI starts with an initial configuration file in $GWHOME/currentGW/etc/GWmain.conf. This file is created during installation of the software.

The configuration data within the file is defined as dynamic, static, or constant:

•Dynamic data can be modified by a provisioning session (see Appendix A, “MML User Interface and Command Reference”). It can be activated on the currently running Cisco HSI.

•Static data can be modified by a provisioning session but cannot be activated on a running Cisco HSI. Changes to dynamic and static data can be written to a separate provisioning file (in $GWHOME/currentGW/var/prov/configname/session.dat) that can be used during subsequent restarts of the Cisco HSI.

•Constant configuration data is contained within the configuration file and cannot be modified by provisioning sessions. Constant configuration data can be modified only by system technicians or administrators who use UNIX editing tools. This data is replicated from the initial configuration file into the provisioning files, and is included in subsequent provisioning sessions.

Examples of the use of constant data are given in Appendixes D, E, F, and G. These appendixes determine the mapping of cause values for incoming and outgoing H.323 and Enhanced ISDN User Part (E-ISUP) messages. System technicians can modify these values in the initial configuration file to explicitly choose the mappings for their system.

When a provisioning session creates a new configuration file, it also verifies that provisioned data is within allowable ranges and indicates this in the start of the file. It checksums the configuration file and writes the checksum as $GWHOME/currentGW/var/prov/configname/checksum.dat. When the Cisco
