INTRODUCTION
CHAPTER 1 INTRODUCTION
1. GENERAL
This manual describes routine system maintenance procedures and fault repair procedures. This chapter ex-
plains how to follow the manual and provides precautions pertaining to maintenance jobs as a whole. Be sure
to read this chapter thoroughly before starting the required maintenance project.
2. HOW TO FOLLOW THIS MANUAL
If technicians engage in a fault repair with a sufficient amount of knowledge of the system (system configura-
tions, controlling systems, functions, etc.), the time spent repairing the system is minimized. This manual pro-
vides explanations about the system, while placing emphasis on system configurations, controlling systems,
and functions. If faults of all conceivable cases are to be assumed for the explanations, the explanations may
lack reality and be more difficult to understand. Therefore, this manual provides the explanations on the basis
of the following points:
(1) It is very important to determine whether the fault occurred in the PBX or at any of the peripheral equip-
ment.
(2) In case the PBX is faulty, explanations are provided about the actions to take until the faulty circuit card/
cards are identified.
(3) Explanations will be omitted pertaining to the following faults:
 Fault of peripheral equipment (MAT, telephone sets, etc.)
 Fault due to an error in office data assignment
 Fault due to an error in installation procedure (an error in circuit card switch setting, cross-connection,
etc.)
(4) How to Read This Manual
 When a fault is to be repaired for the first time
See Section 3, How to Read Precautions, Diagnostic, 
and Fault Repair Information, Chapter 2.
See Section 4, Repo rting Fault to NEC, in Chapter 2. Go to Chapter 5.

 When only the contents of a system message needs to be known, or when a fault is to be diagnosed
from a system message
 When the range of faulty conditions has been specified and a faulty circuit card can be assumed
 When investigating the system for the purpose of a fault repair
 When replacing a unit/circuit card with a spare
 When performing routine maintenance
