Features
Directory Names
Each station, station group and C.O. line may be assigned a directory name (maximum 11
characters). In addition, each personal speed dial number, system speed dial number may
be assigned a name (maximum 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 (in 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 repeatedly (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 will print on SMDR (if
provided) with a “DE” DISA error flag.
Distinctive Ringing
Users will know 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 to 2500 ms.
Door Phones
The door phone interface module (DPIM) provides for connection of a door phone to a DLI
port. Pressing the key on the door phone produces a distinctive ring (three short rings
repeated) at the assigned station or station group. If not answered within a programmable
time, the system will release the door phone and stop 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.
