DISA SECURITY
Telephone fraud and long distance theft continue to increase; therefore, we have intro-
duced a DISA security system. If an incorrect DISA passcode is entered repeatedly
(as is the case with "hackers"), the DISA system can be automatically disabled tempo-
rarily. Both the number of incorrect passcode attempts and the time that DISA is dis-
abled are programmable. In addition, all failed attempts to access DISA will print on
SMDR (if provided) with a "DE" DISA error flag.
WARNING: As it is impossible to prevent unauthorized access to your telephone sys-
tem by hackers, we suggest that you do not turn the DISA feature on unless you intend
to use it. If you do use this feature, it is good practice to frequnetly change passcodes
and periodically review your telephone records for unauthorized use.
DISTINCTIVE RINGING
Users will know the type of call they receive by the type of ring that they hear. Outside
calls have a single ring repeated while internal calls have a double ring repeated.
DIRECT INWARD DIALING (DID)
The DCS COMPACT can use local telephone company-provided DID service via an
E & M trunk. When programmed, anyone dialing a user's personal number rings di-
rectly to that user's office. DID calls to a busy station have the option to return busy
signal to the C.O. or return ringback to the C.O. When ringback is selected, the called
station receives off-hook ring. Multiple DID numbers can ring the same extension or
station group and display keysets show a DID directory name when ringing if a name
has been programmed. DID calls can be assigned both a day and night ring destina-
tion. This allows routing of DID calls that have one destination during the system Day
mode to be routed to a different destination during the system Night mode. DID calls
that are directed to ring a voice mail machine can be identified by a special digit
Voice Mail Integration). As it is possible to program E&M trunks to follow the DID
translation tables, the system can use both way DID type service.
DNIS (DIALED NUMBER IDENTIFICATION SERVICE)
DNIS is an incoming service provided by the telephone service provider that translates
the 10 or 11 digit numbers dialed into 3 or 4 digits, then sends them into the DCS
COMPACT. The DCS COMPACT is considered enhanced because it provides sepa-
rate day and night destinations with name display allowing greater call coverage. The
DCS COMPACT supports DNIS on E&M tie line service.
DOOR LOCK RELEASE (PROGRAMMABLE)
After answering a call from the door phone, users can dial a code to activate a contact
closure. This can be used to operate a customer-provided electric door lock release
mechanism. The contact closure timer is programmable from 100–2500 ms.
