General Features
c)
The DISA OGM(s) should be recorded by the Manager or an Operator.
d)
The OGM Type should be set to "DISA" under OGM Group setting.
• DISA Delayed Answer Time
A DISA call is answered after a ringback tone is returned to the caller after the "DISA
Delayed Answer Time" expires. The caller can dial while hearing the OGM message.
• DISA User Code
This system can store up to 32 programmable DISA user codes with a COS (Class of
Service) level for each. Each code should be unique.
• DISA User Code Entry Failure
If the DISA caller fails to enter the valid DISA user code three times consecutively, the call
will be disconnected.
• DISA built-in Automated Attendant Table
This system can store up to 8 DISA built-in auto attendant number tables, each having 10
one-digit numbers.
• DISA built-in Automated Attendant Number
The DISA built-in auto attendant number may be the same as the first digit of other numbers
(extension number, Floating Number, etc.). To avoid confusion, the system waits for the
second digit for a pre-programmed amount of time (default: 1 second). If the second digit
is not dialed before the timer expires, the system assumes that the first digit is a DISA built-
in auto attendant number.
• Call Forwarding - to CO or TIE Line
When a DISA call is forwarded to an outside party, the caller is not required to enter a DISA
user code regardless of the Security modes.
• CO-to-CO line call duration
The duration of CO-to-CO line calls can be limited by System Programming. When a
specified period of time (default:10 min) expires, both lines are disconnected unless the
caller prolongs the duration time, if available. A warning tone is sent to both parties 15
seconds before the time limit at 5-second intervals.
• Prolonging the duration of CO-to-CO line call is possible. To prolong the call duration, the
caller should press any dialpad key except . The amount of prolonging is set by "DISA
Prolong Time" (0 to 7 minutes). (If this is set to zero, then prolonging is disabled.)
Depending on System Programming <Section 2.8 System Option, "13. DISA prolong
operation" in the Programming Guide>, the call duration can be prolonged 10 times or
without limit.
• To detect the end of a CO-to-CO line call, CPC Signal Detection and Tone Detection can
be assigned.
• Tone Detection
The following three ways of "Tone Detection" are provided <Section "3.2 Trunk Group" in
the Programming Guide> to disconnect a CO-to-CO line call.
1. Cyclic Signal Detection:
Used to disconnect the trunk line when the system detects a cyclic signal during a CO-
to-CO line call by DISA or AGC.
2. Continuous Signal Detection:
Used to disconnect the trunk line when the system detects a continuous signal during a
CO-to-CO line call by DISA or AGC.
