System Testing and Diagnostics

14.1 Introduction

This chapter describes the IMACS-200 comprehensive set of built-in diagnostic tools that enable the operator to remotely troubleshoot and resolve problems. Throughout the user port chapters in this system reference guide are brief explanations of system testing and problem solving. However this chapter was designed to provide a “full picture” of what this Integrated Access System is capable of providing.

14.2 Integral Test Capabilities

The Integrated Access System provides diagnostics capabilities to resolve problems. There are system-generated alarm messages described in Chapter 4. System Configuration and Operation, the integral diagnostics capabilities of this system include Bit Error Rate Testers (BERTs) on data ports, tone generators on analog voice ports, the ability to manipulate the analog leads and the digital signaling bits of voice circuits.

The ability to initiate loopbacks at various points in a circuit, coupled with the ability to generate and receive test signals and to collect performance and error information, enable the operator to systematically troubleshoot circuit problems. It allows the operator to determine if the problem resides in the system. Since all of these diagnostic tools can be operated from a remote VT100 terminal, troubleshooting begins immediately without dispatching an on-site technician.
