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.
The information in this book is intended for use by:
■ 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, or
■ The user’s assigned maintenance technician. The technician is expected
to have a knowledge of telecommunications fundamentals and of the
DEFINITY
Enterprise Communications Server Release 5 Systems to the
extent that the procedures in this book can be performed, in most cases,
without assistance.
