1 Introduction

This chapter describes the content and structure of the user's guide, indicates how to obtain help, details where to find related documentation, and provides other general information.

1.1 Overview

Unsolicited Alarm and Information Messages Reference describes the EAGLE system unsolicited alarm (UAM) and unsolicited information (UIM) messages sent to the system terminal whenever there is a system fault, whenever a previous fault condition is corrected, or when a subsystem, equipment, and/or service is placed in or taken out-of-service. Each message has a trouble code and text associated with the trouble condition.

Note:

EAGLE supporting ANSI networks make use of the LNP and SEAS features. EAGLE supporting ITU networks do not include these systems.

The manual is organized as follows:

Introduction provides general information about the organization of this manual.
Message Type describes the different alarms and message types used in the EAGLE.
UAM and UIM Troubleshooting Procedures provides procedures to use in response to unsolicited alarm messages (UAMs) and unsolicited information messages (UIMs) displayed by the EAGLE.
In addition, the appendices of this manual provide useful reference material for maintenance, diagnostic, and troubleshooting activities:
- Appendix A: UAM Balancing Matrix
- Appendix B: Unsolicited Output Message Groups
- Appendix C: Auto-Inhibit Hardware Verification Codes

1.2 Scope and Audience

This manual is intended for maintenance personnel who must maintain the EAGLE. The technician should be familiar with SS7 protocols. The manual provides preventive and corrective procedures that will aid maintenance personnel in maintaining the EAGLE.

Preventive maintenance procedures are routines to be carried out on a scheduled basis to help prevent system failures. These routines are industry-standard recommendations and may be adopted to fit any company maintenance plan.

The corrective maintenance procedures are those used in response to a system alarm or output message. These procedures are EAGLE-specific and aid in the detection, isolation, and repair of faults.
