System Features Direct Inward System Access (DISA)
Revised April 2000 DBS 824-3.0/3.2-700 1-15
For security reasons, one incoming DISA code may be assigned. If an
incoming code is assigned, it must be entered as soon as the DISA trunk
answers.
Two outgoing DISA codes are assigned (1111 and 9999 by default). One of
the two outgoing codes must be entered before the user dials an outgoing call.
Operation
To make a DISA call to an extension:
1. Dial the DISA trunk number.
2. Once you hear DISA tone from the DBS 824, enter the 4-digit DISA code
(if an incoming DISA code is assigned).
If the incoming DISA code is not assigned, proceed to the next step.
3. Dial the extension number.
To make a DISA call to an outside number:
1. Dial the DISA trunk number.
2. Once you hear DISA tone from the DBS 824, enter the 4-digit DISA code
(if an incoming DISA code is assigned).
If the incoming DISA code is not assigned, proceed to the next step.
3. Dial #7 plus the 4-digit outgoing DISA code.
Two outgoing DISA codes are assigned. Either may be used after the #7.
4. Dial the number of the trunk group you want to use (81-86 or 9).
