Introduction; Functional Overview; Isolating And Correcting Troubles - Lucent Technologies MERLIN 820 Service And Maintenance Manual

Introduction

Even the magic of the MERLIN™ communications system sometimes fails. The problem
may be a user error, installation problem, or faulty component. Usually you can correct the
problem on the spot without returning any equipment for maintenance exchange.
The Service and Maintenance Manual: Models 206, 410, and 820 is intended for use by both
the customer and the service technicians. This troubleshooting manual is divided into four
parts:
Functional Overview describes each communications system component and its use.
Isolating and Correcting Troubles includes step-by-step procedures to help you isolate a
problem to a user error or a specific component. Most procedures require no tools. A few
procedures require a screwdriver or a basic Touch-Tone or rotary telephone (a Power
Failure Transfer Telephone will work).
CIBs includes copies of customer instruction booklets shipped with the components. The
CIBs describe the functional features and installation of each component.
Index lists problems, features, and components. It will help you find the information you
need quickly.
