Direct Inward System Access (DISA) Programming
Through the DISA programming routines, you can configure a system to allow outside callers to call directly into
the system. DISA callers can dial authorization codes that allow them to use the system’s features that are
normally available only to inside callers.
NOTE: It is possible to use the automatic route selection (ARS) feature (Section 12) along with the DZSA feature
to route DZSA calls that pass through the system. Zf you enable this application, you may need to add
pauses in the ARS modtfj digits table (Section 14.4.4) to accountfor the time delay the system experiences
in obtaining the CO dial tone. The amount of time delay varies for each installation; therefore, you must
test your installation to determine the time required to obtain a CO dial tone when using the DZSA feature.
You can then adjust the system timing pause time or add multiple pauses to o$set this delay.

DISA Cofigura tion (DISA Specific Programming)
Description:
The purpose of the DISA specific programming is to perform the following tasks:
- Enable extensions where day/night DISA calls will be routed when call-routing is necessary,
- Enable proprietary voice mail to receive DISA calls and route the calls to a dedicated mailbox
that holds the appropriate intercept greetings,
- Select access Iockout time (the amount of time that the line remains locked-out from use
after invalid conditions occur-such as, when a caller repeatedly dials an invalid
authorization code),
- Select the timeout period for DISA extensions that ring without answer (RNA),
- Select the maximum timeout period for the reminder tone that sounds during an in-process
call when the DISA caller is using an outside line and the system has no disconnect
supervision. This tone sounds at set intervals to remind the caller that he or she must dial
a code (any single digit) or be disconnected within 10 seconds,
- Select the option to either route a DISA call or drop it after caller dials an invalid
authorization code
