mode. any outside caller may make CO tails. In CO Line
Security
mode. it is necessary to enter a pre-assigned
DISA
user code to make CO calls. This prevents the caller from
making unauthorized calls. However. when makin? a CO
call by Call Forwarding - to CO Line, the call is
exceptionally permitted.
An Outgoing Message can be programmed for the DISA
feature. When a caller reaches the DISA line, a pre-
recorded message will greet the caller. Two different
DISA messages may be recorded by Operator 1. Thus. one
message may be used in day mode and the other in night.
or they can be used for different CO lines.
(
1) An optional DISA Card must be installed.
(3) The Floating Station number of the DISA message should be
assigned as the DIL 1:
1
destination. This assigns the DISA line
'
and the message accessed by external callers.
(3) The DISA message(s) should be recorded by Operator 1.
Only one DISA card can be installed per system. During System

same system.
A DISA call is answered after ringback tone is returned to the caller
after the DISA Delayed Answer Time expires. The caller can dial
during the message.
The DISA line can be used to originate CO calls if the security code (if
required) has been dialed.
The floating number of a DISA message may be selected as the
destination of Intercept Routing.
This system can store up to four programmable DISA user codes.
Each code should be unique. It is possible to assign a Class of Service'
number to each code. In CO Line Security system, the caller must
enter one of the stored codes after accessing a CO line. The Class of
Service of the code defines Toll Restriction.
The duration of CO-to-CO calls can be limited. '.When the specified
time expires, both lines are disconnected unless the caller re-tries or
prolongs the time, if available. Warning tone is generated to both
parties 15 seconds before the time-limit at five-second intervals.
Prolonging the call duration can be allowed from 'one to seven minutes
or disallowed. The caller can attempt this several times to prolong it
further.
To detect the end of a CO-CO call, CPC Signal Detection and Tone
Detection can be assigned.
