Conditions
Calling an extension
• You can choose Non Security, Trunk Security or All Security mode. In All Security
mode, the caller must enter a pre-assigned DISA user code to make intercom calls.
• If the DISA call is not answered within a specified period of time (DISA IRNA Time:
60 seconds [default]), the system redirects it to the pre-determined IRNA destination.
If IRNA destination is not programmed, the DISA call will be disconnected 10 seconds
later.
Calling an outgoing CO line
• You can choose Non Security, Trunk Security or All Security mode. In Trunk Security
mode, the caller must enter a pre-assigned DISA user code to make outside calls. In All
Security mode, the caller must enter a pre-assigned DISA user code to make both CO
and intercom calls.
General
• If the caller does not dial any digits during and after the playback of DISA outgoing
message, the system will direct him to the pre-determined destination (Intercept
Routing). "Intercept Routing" is activated 5 seconds after (default) or immediately after
the playback depending on System Programming.
• 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
The KX-TD500 System can store up to 32 programmable DISA user codes with a COS
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 eight DISA built-in auto attendant number tables and each
table includes 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 until 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 the
specified time expires (default:10 min), both lines are disconnected unless the caller re-
tries or extends the duration time, if available. A warning tone is sent to both parties 15
seconds before the time limit at 5-second intervals.
• During a CO-to-CO line call, the caller can prolong the duration of the call by pressing
any dialpad key (except *). The amount of prolonging is determined by System
