This handbook explains the functions and operating
procedures of stations for TOA's EXES-6000 Intercom

exchange or tie-line system) and exchanges EX-630.
Designed for connection of up to 3 exchanges, the EXES-
6000 system permits you to talk with the person in the
remote area, and also to increase the number of stations
which one (1) exchange cannot cover.
This handbook is comprised of the following 3 chapters:
Chapter 1. Basic functions, their operating procedures
and all functions.
Chapter 2. Functions and operating procedures of single
exchange system (a maximum of 256
stations).
Chapter 3. Functions and operating procedures of tie-
line system (a maximum of 768 stations).
Refer to Chapters 1 and 2 for single exchange system
and to Chapters 1 and 3 for tie-line system.
Please note that performances of some functions are
restricted in the tie-line system.
You need not read all the instructions given in this hand-
book but it is necessary to read the instructions on those
functions employed in your system. The following guide-
lines will help you select the pages that yo u should read.
Selecting different functions made available by placing the
Privacy Switch in the "ON" position
The EXES-6000 System is designed to allow either "P V"
typ operation (The system having Privacy function) or
"NP" type (Withou t Privacy function) to be selected by
turning on or off a switch inside the exchange. It is impos-
sible to make one station the "NP" type and another the
"PV" type in the same system.
The function provided when the Privacy switch is in the ON
position is different between the "PV" and the "NP" type.
Therefore, read the page marked if your system
is of the "PV" type and the Page if it is of t he
"NP" type.
