Programming <Section 2.5 System Timer, "DISA Prolong Time" in the Programming
Guide>. If this parameter is set to zero, the caller cannot prolong the call duration. The
caller can repeat the prolonging operation 10 times or without limit depending on the
System Programming <Section 2.8 System Option, "13. DISA prolonging operation" in
the Programming Guide>.
• 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.
3. Silence Detection:
Used to disconnect the trunk line when the system detects no signal during a
CO-to-CO line call by DISA or AGC.
• DISA Call Re-try by Pressing
The " " key can be entered during a DISA call. The action taken by the system depends
upon System Programming <Section 2.8 System Option, "14. Dialing " " in DISA CO-
to-CO talking" in the Programming Guide>. If "Disconnect and make a new call" is
selected, then the system will disconnect the current call and prepare for a new call.
Otherwise, the
• Intercept Routing
The Floating Number of a DISA OGM Group can be selected as the destination of
Intercept Routing.
• What if the destination extension is busy?
If the destination extension has enabled Call Waiting, then he will hear the Call Waiting
tone. Otherwise, the caller may hear a busy tone, or the call is redirected to the IRNA
destination. This is determined by System Programming <Section 2.8 System Option,
"17. Destination Busy-DISA" in the Programming Guide>.
• What if an illegal number is dialed?
The caller may hear a reorder tone, or the call is redirected to the IRNA destination. This
is determined by System Programming <Section 2.8 System Option, "21. Illegal
Number-DISA" in the Programming Guide>.
• How many times does the IRNA destination ring?
This is determined by System Programming <Section 2.5 System Timer, "Call
Forwarding — No Answer Time" in the Programming Guide>.
