4.32 DIRECT INWARD SYSTEM ACCESS (DISA) 
Description 
This feature allows an external ca!ler to access the system by select- 
ing a special trunk and dialing a security code. After the code is dialed, 
the system returns dial tone to the caller, who may then access any 
features in the DISA trunk’s COS except those which require a switch- 
hook flash. 
Optionally, the external caller can be forced to enter a special account 
code rather than the standard DISA access code. 
Conditions 
The outside caller must use a DTMF telephone. 
The security code may be one to five digits in length. 
The same security code applies to all DISA calls. 
If a caller dials an invalid code, the call is dropped after three digits 
have been dialed. 
Reorder tone is not returned to the caller. 
A DISA trunk may be used as a standard CO trunk. 
Access to the allowed features is controlled by the COS assigned to 
the trunk. 
Switchhook flash is not possible on a DISA trunk.

Form 01 (System Configuration).
