Direct Inward System Access (DISA)

(All Versions)
Description
Direct Inward System Access (DISA) gives off-site users dial-in access to the
DBS. Users access DISA by dialing a 7-digit number assigned to a DISA
trunk.
For security reasons, one incoming DISA code and two outgoing DISA codes
can be assigned. If an incoming code is assigned, it must be entered as soon as
the DISA trunk answers. An outgoing code must be entered before the user
dials an outgoing call.
Operation

1. Dial the DISA trunk number.
2. Once you hear DISA dial tone from the DBS, enter the 4-digit DISA code
3. Dial the extension number.
To make a DISA call to an outside number:
