DIRECTORY NAMES
Each station, station group and C.O. line may be assigned a directory name (maxi-
mum 11 characters). In addition, each personal speed dial number, system speed
dial number and entry in the DID translation table may be assigned a name (maxi-
mum 11 characters). These names are displayed during calls with these ports and
in the case of station and speed dial names, can be used to originate calls. See the
Dial by Name feature (Station Features).
DISA SECURITY
Telephone fraud and long distance theft continue to increase; therefore, we have
introduced a DISA security system. If an incorrect DISA passcode is entered re-
peatedly (as is the case with “hackers”), the DISA system can be automatically
disabled temporarily. Both the number of incorrect passcode attempts and the time
that DISA is disabled are programmable. In addition, all failed attempts to access
DISA print on SMDR (if provided) with a “DE” DISA error flag.
DISTINCTIVE RINGING
A user knows the type of call received by the type of ring heard. Outside calls have
a single ring repeated while internal calls have a double ring repeated.
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.
DOOR PHONES
The door phone interface module (DPIM) provides for connection of a door phone
to a DLI port. Pressing the button on the door phone produces a distinctive ring
(three short rings repeated) at the assigned station or station group. If not an-
swered within a programmable time, the system releases the door phone and stops
the ringing. Stations may call the door phone directly and monitor the surrounding
areas.
DOOR PHONE NIGHT RING
The ring destination of door phone calls may be different at night than during the
day. For example, large factories may want these calls directed to a security desk
after hours.
E & M TIE LINES
Your office can be connected to another office with a tie line. Use it to make calls to
stations in the other system. If programming allows, you can access lines in the
other system to make outside calls. Tie line calls can be put on hold, transferred
and conferenced in the same way as are other outside calls. Users accessing the
tie line from the other system can get a line in your system and make outgoing
calls. These calls can be controlled by assigning a dialing class to the tie line. Your
