Direct Inward System Access (DISA)

Allows an outside caller to access specific system features as if the caller is an extension in
the system. The caller can have direct access to features such as:
• Placing an incoming call to an extension, extension group or operator. The caller also
has the option of dialing the route for an extension using a 1 digit number (DISA built-
in auto attendant number) via DISA calls.
• Calling an external party.
One of the following must be selected in program [511] to have direct access to these
features:
(1) None Security, (2) Trunk (Outside (CO) Line) Security, or (3) All Security.
None Security: Any caller can make outside or intercom calls.
Trunk Security: A pre-assigned DISA security code must be entered to make outside
All Security:
This prevents the caller from making unauthorized calls. However, when making an outside
call by Call Forwarding – to Outside (CO) Line, the call is allowed (exception).
The DISA feature operates without an optional card installed. If an outgoing message
(OGM) which greets a caller and gives information, or fax detection is required, an optional
OGM/FAX Detection Card must be installed. The system can detect a FAX (CNG) tone
according to program [514]. An OGM can be programmed in program [502] (
Message (OGM)" in this section). When a caller reaches a DISA line, a message will greet
the caller. Two different DISA messages can be recorded by the operator or manager. For
example, one message can be used in day mode and the other in night mode, or they can be
used for different outside (CO) lines. If an optional OGM/FAX Detection Card is not
installed, the caller will hear a short beep instead of the OGM (Internal DISA).

• "DISA" must be assigned to outside (CO) line(s) as the outside (CO) line mode in
!
programs [414] through [416].
• A DISA call is answered after a ringback tone is returned to the caller after the DISA
Delayed Answer Time assigned in program [504] expires. The caller can dial during the
message or after the tone.
• This system can store up to 10 programmable DISA built-in auto attendant numbers in
program [501]. Each number is 1 digit.
• The DISA built-in auto attendant number may be the same as the first digit of other
numbers (extension number, etc.). To avoid confusion, the system waits for the second
digit for a preprogrammed amount of time in program [517] (default: 2 seconds). If the
timer expires, the system will assume that the first digit is a DISA built-in auto attendant
number.
• Only one OGM/FAX Detection Card can be installed .
• The DISA line can be used to make outside calls, if a security code assigned in program
[512] (if required) has been dialed.
• This system can store up to 4 programmable DISA security codes. Each code should be
different.
• When a wrong DISA security code is entered, 3 beeps will be heard. The call will be
disconnected after 3 failed attempts. If you enter a security code a second and third time,
dialing
calls.
A pre-assigned DISA security code must be entered to make both
outside and intercom calls.
