DISA Security
Telephone fraud and long-distance theft are a serious concern. The iDCS100 provides a
strong 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 al-
lowed number of incorrect passcode attempts and the time for which 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
The type of call received by a user can be recognised by the type of ring heard. For example,
in the UK, outside calls have a double ring repeated while internal calls have a single ring re-
peated.
In addition, any trunk or station can be programmed to ring a keyset with a predefined ring
tone (selectable between 1 and 8), or to ring a single line telephone with a predefined ca-
dence (selectable between 1 and 5). This provides for easy identification of special lines or
extensions that ring your phone.
Door Lock Release (Programmable)
After answering a call from the door phone, users can dial a code to activate a contact clo-
sure. This can be used to operate a customer-provided electric door lock release mechanism.
The contact closure timer is programmable in the range 100–2500 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 re-
peated) at the assigned station or station group. If not answered 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 phones follow the system ring mode plan.
Executive Barge-in (Override)
The feature allows specially programmed stations with a Barge-In key to override the
automatic privacy of another station or outside trunk. Programming allows barge-in with or
without a warning tone. Stations may also be programmed as “secure” so that they cannot be
barged-in on.
With Warning Tone
When the barge-in with tone option is set, the barging-in keyset has its microphone on and the barged-
in on station receives an override display. A double burst of warning tone sounds and repeats every 10
seconds. This feature does not work from single line telephones.
Without Warning Tone
When the barge-in without tone option is set, the barging-in keyset has its microphone muted and the
barged-in on station does not receive an override display. This feature does not work from single line
telephones.
WARNING: Barge-in without tone may violate laws concerning the right to privacy.
