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. If the extension does not have a line key, the call rings an idle
CALL 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 Class of Service
DISA Class of Service provides features and dialing restrictions for DISA callers. This allows you
to control the capabilities of the DISA callers dialing into your system. When a DISA caller Þrst
accesses the system, they must enter a DISA password before proceeding. The system associates
the password entered with a speciÞc 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 doesn't 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's Trunk Group
Access or Automatic Route Selection - whichever is enabled.
● Trunk Group Access
DISA callers may be able to access a speciÞc trunk group for outgoing calls through the sys-
tem. To access a Trunk Group, the user dials Service Code 804 followed by the Trunk Group
number (e.g., 1). This allows the DISA caller to place an outgoing call over the selected
group. Trunk Group Access bypasses the system's Trunk Group Routing/ARS/Trunk Access
Maps. As with dial 9 access, any toll charges are incurred by the system. Also see Direct
Trunk Access below.
● Common Abbreviated Dialing
The system's Common Abbreviated Dialing bins may be available to DISA callers. This could
save the DISA caller time when dialing.
● Operator Calling
A DISA caller may be able to dial 0 for the system's 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 speciÞc trunk for outgoing calls through the system. To
directly access a trunk, the user dials Service Code #9 followed by the trunk's number (e.g.,
001). This allows the DISA caller to place an outgoing call over the selected trunk. Direct
Trunk Access bypasses the system's Trunk Group Routing/ARS/Trunk Access Maps. As with
dial 9 access, any toll charges are incurred by the system. Also see Trunk Group Access above.
● Call Forward
DISA callers may be able to set Call Forwarding to redirect an extension's calls to another
extension. Call Forwarding ensures that the user's calls are covered when they are away from
their work area.
●
DISA/Tie Trunk Barge In
The DISA/Tie Trunk Barge In option allows a tie line caller to break into another extension's
established call. This sets up a three-way conversation between the intruding party and the
two parties on the initial call.
DISA Toll Restriction
The digits a DISA caller dials for an outgoing call may be subject to the system's Toll Restriction.
For example, Toll Restriction can prevent users from dialing a 1-900 service. When an incoming
DISA caller tries to use system trunks to dial 1-900, Toll Restriction will deny the call.
