Direct Inward System Access (DISA)
Description
DISA permits outside callers to directly dial system extensions, trunks and selected features. This
could help an employee away from the office that wants to directly dial co-workers or use the company
trunks for long distance calls. To use DISA, the employee:
•
Dials the telephone number that rings the DISA trunk
•
Waits for the DISA trunk to automatically answer with a unique dial tone
•
Dials the 6-digit DISA password (access code)
•
Waits for a second unique dial tone
•
Accesses a system trunk, uses a selected feature or dials a system extension
DISA calls ring system extensions like other outside calls. If an extension has a line key for the DISA
trunk, the call rings that key.
You can set DISA operation differently for each Night Service mode. For example, a trunk can be a
normal trunk during the day and a DISA trunk at night. You can also set the routing for DISA trunks
when the caller dials a busy or unanswered extension, dials incorrectly or forgets to dial.
DISA allows 15 users, 15 DISA Classes of Service and 126 trunks.
DISA Class of Service
DISA Class of Service provides features and dialing restrictions for DISA callers. This allows you to
control the ability of the DISA callers dialing into your system. When a DISA caller first accesses the
system, they can be prompted to enter a DISA password before proceeding. The system associates
the password entered with a specific user number, which in turn has a Class of Service. If the Class of
Service allows the action (such as making outgoing trunk calls), the call goes through. If the DISA
Class of Service does not allow the action, the system prevents the call. The DISA Class of Service
options are:
•
Trunk Group Routing/ARS Access
When a DISA caller dials into the system, they may be able to dial 9 and place outside calls. Any toll
charges are incurred by the system. The call follows the system Trunk Group Access or Automatic
Route Selection - whichever is enabled.
•
Trunk Group Access
DISA callers may be able to access a specific trunk group for outgoing calls through the system. To
access a Trunk Group, the user dials Service Code
804
followed by the Trunk Group number (Trunk
Groups 1~25). This allows the DISA caller to place an outgoing call over the selected group. Trunk
Group Access bypasses the system Trunk Group Routing/ARS/Trunk Access Maps. As with dial
9
access, any toll charges are incurred by the system.
•
Speed Dial - System/Group/Station
The System Speed Dial dialing bins may be available to DISA callers. This could save the DISA caller
time when dialing. To access the System Speed Dialing bins, the caller dials Service Code
#2
and
the System Speed Dial Bin number.
•
Operator Calling
A DISA caller may be able to dial 0 for the system operator.
•
Paging
Internal and External Paging may be available to DISA callers. This allows co-workers in adjacent
facilities, for example, to broadcast announcements to each other.
•
Direct Trunk Access
DISA callers may be able to select a specific trunk for outgoing calls through the system. To directly
access a trunk, the user dials Service Code
#9
followed by the trunk number (e.g., 001). This allows
the DISA caller to place an outgoing call over the selected trunk. Direct Trunk Access bypasses the
system Trunk Group Routing/ARS/Trunk Access Maps. As with dial
9
access, any toll charges are
incurred by the system.
