during a conversation. Set this feature if your extension has a data communication device such as a 
computer or fax machine connected, to ensure secure data transmission.CO-to-CO Line Call Duration
The length of outside-to-outside (CO-to-CO) line calls may be limited through system 
programming.
Both outside parties will hear a warning tone 15 seconds before a specified time limit. 
When the timer expires, the call is disconnected.
The originating extension user will hear a ring tone or an alarm tone before the time limit.

 1.3.40 Executive Busy Override—Extension
 1.3.41 Executive Busy Override—Outside (CO) Line
When an outside caller dials a specified telephone 
number of the PBX, a prerecorded Direct Inward 
System Access (DISA) outgoing message (OGM) 
can greet the caller and give information about how 
to access an extension. The operator does not 
need to be involved. If there is no recorded 
message, the caller will hear a short beep instead 
of the DISA OGM. The operator or manager can 
record, play, or erase a DISA OGM. Refer to 2.1.5 
Outgoing Message (OGM) for DISA
The caller may also be able to access system 
features or call an outside party by using the 
callers password (DISA security code), depending 
on the security mode. For more details, refer to 
1.1.41 Direct Inward System Access (DISA) in 
the Feature Manual.

To call an outside party
WA R N I N G
There is a risk that fraudulent telephone calls will be made using the Outside-to-
Outside (CO-to-CO) Line Call feature of DISA.
The cost of such calls will be billed to the owner/renter of the PBX.
To protect the PBX from this kind of fraudulent use, we strongly recommend:
a)Enabling DISA security (Trunk Security or All Security).
b)Keeping DISA security codes secret.
c)Selecting complex, random codes that cannot be easily guessed.
d)Changing codes regularly.
 If you dial 4 digits or more when dialing an extension number, the call will be disconnected. 
When you dial an invalid extension number of 3 digits or less, the call is redirected to the 
preprogrammed intercept destinations or disconnected, according to system 
programming.
CO-to-CO Line Call Duration
The length of outside-to-outside (CO-to-CO) line calls may be limited through system 
programming. 
Both the outside caller and the outside destination will hear a warning tone 15 seconds 
before a specified time limit. When the timer expires, the call is disconnected.

 If the DISA Automated Attendant (AA) service is used, you can access the desired party 
simply by pressing a preprogrammed single-digit number (DISA AA number) while or after 
hearing a DISA OGM or after a short beep. AA menus can be up to 3 levels deep.
 If you enter an invalid security code 3 times consecutively, the call will be disconnected 
automatically. If you enter a DISA security code a second and third time, dialing   is not 
necessary.

1.3.36 Do Not Disturb (DND) Override
You can call users who have set the Do Not Disturb (DND) feature, if your extension is permitted through 
system programming. The FWD/DND (Call Forwarding/Do Not Disturb) button light shows the current status as 
follows:
Off: Neither feature is set.
Red on: DND mode
Flashing red slowly: FWD mode
 If your extension has set this feature, calling extensions will hear a DND tone.
 If this feature is set, the FWD feature does not function.
 Extensions can override this feature and call extensions in DND mode (DND Override) if 
they are allowed to do so through system programming.
 Outside (CO) line calls can be received at your extension, but the telephone will not ring. 
The corresponding CO button will flash when an outside (CO) line call is received, and you 
can answer the call by pressing this button.
 Even if this feature is set, timed reminder alarms, camp-on recall tones, and hold recall 
tones (ring tones or alarm tones) will still ring.
