About This Book
Purpose
This book contains the information needed to monitor, test, and maintain
DEFINITY
®
Enterprise Communications Server (ECS) csi system and covers
many of the faults and troubles that can occur in the system. Most maintenance
requirements are simple procedures due to the modular, self-testing nature of the
system.
Simple, traditional troubleshooting methods are sometimes sufficient to locate
and clear faults. The traditional methods include terminal substitution, visual
inspections, continuity checks, and clarification of operating procedures with
users.

■ A maintenance technician dispatched to a DEFINITY System site in
response to a trouble alarm or a user trouble report
■ A maintenance technician located at a remote maintenance facility
■ The user’s assigned maintenance technician. The technician is expected
to have a knowledge of telecommunications fundamentals and of the
DEFINITY
Enterprise Communications Server systems to the extent that
the procedures in this book can be performed, in most cases, without
assistance.
