3 Features D Direct Inward System Access (DISA) Description Allows an outside caller to access specific system features after hearing a short beep 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, operator or ring group. The caller also has the option of dialing the route for an extension using a one digit number (DISA built-in auto attendant number) via DISA calls. • Calling an external party. One of the following must be selected to have direct access to these features: (1) None Security, (2) Trunk (Outside (CO) Line) Security, or (3) All Security. In None Security mode, any caller can make outside or intercom calls. In Trunk (Outside (CO) Line) Security mode, a pre-assigned DISA security code must be entered to make outside calls. In All Security mode, a pre-assigned DISA security code must be entered to make both outside and intercom calls. This prevents callers from making unauthorized calls. However, when making an outside call by Call Forwarding - to Outside (CO) Line, the call is allowed (exception). Conditions • The following items are required for the DISA feature. - "DISA1" must be assigned to outside (CO) line(s) as the outside (CO) line mode. • After the DISA Delayed Answer Time expires and a ringback tone is returned to the caller, a DISA call will be answered. The caller can dial after the tone. • This system can store up to ten programmable DISA built-in auto attendant numbers. Each number is one 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 (default: 2 seconds). If the timer expires, the system will assume that the first digit is a DISA built-in auto attendant number. • The DISA line can be used to originate outside calls if a security code (if required) has been dialed. • This system can store up to four programmable DISA security codes. The number of digits of the codes can be programmed (default: 4 digits). Each code should be different. • The duration of outside-to-outside (CO-to-CO) line calls can be limited. When the specified time expires, both lines are disconnected. A warning tone is sent to both parties 15 seconds before the time-limit. • To detect the end of an outside-to-outside (CO-to-CO) line call, CPC Signal Detection can be assigned. Features 3-47

irect Inward System Access (DISA)
Description
Allows an outside caller to access specific system features after
hearing a short beep 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, operator or ring
group. The caller also has the option of dialing the route for an
extension using a one digit number (DISA built-in auto
attendant number) via DISA calls.
• Calling an external party.
One of the following must be selected to have direct access to these
features: (1) None Security, (2) Trunk (Outside (CO) Line)
Security, or (3) All Security. In None Security mode, any caller can
make outside or intercom calls. In Trunk (Outside (CO) Line)
Security mode, a pre-assigned DISA security code must be entered
to make outside calls. In All Security mode, a pre-assigned DISA
security code must be entered to make both outside and intercom
calls. This prevents callers from making unauthorized calls.
However, when making an outside call by Call Forwarding – to
Outside (CO) Line, the call is allowed (exception).
Conditions
• The following items are required for the DISA feature.
– “DISA1” must be assigned to outside (CO) line(s) as the outside
(CO) line mode.
• After the DISA Delayed Answer Time expires and a ringback tone is
returned to the caller, a DISA call will be answered. The caller can dial
after the tone.
• This system can store up to ten programmable DISA built-in auto
attendant numbers. Each number is one 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
(default: 2 seconds). If the timer expires, the system will assume that the
first digit is a DISA built-in auto attendant number.
• The DISA line can be used to originate outside calls if a security code (if
required) has been dialed.
• This system can store up to four programmable DISA security codes.
The number of digits of the codes can be programmed (default: 4 digits).
Each code should be different.
• The duration of outside-to-outside (CO-to-CO) line calls can be limited.
When the specified time expires, both lines are disconnected. A warning
tone is sent to both parties 15 seconds before the time-limit.
• To detect the end of an outside-to-outside (CO-to-CO) line call, CPC
Signal Detection can be assigned.
