System Testing and Diagnostics Introduction

Chapter 14System 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. Through out the user port
chapters in this system reference guide are brief explanations of system testing and problem
solving. However this chapter was des igned to provide a “full picture” of w hat 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 variou s points in a circuit, coupled with the ability t o
generate and receive test signals and to collect performance and error informa tion, enable the
operator to systematically troubleshoot circuit problems. It allows the operator to deter mine 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.
