Business Feature Package
Direct Trunk Selection
Each station can be allowed access to or denied access from a trunk or trunk group by access code
when LCR is activated. When restricted, the station user must use a trunk key or a route key.
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 and entry in the DID
translation table 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 (Station Features).
Disa Security
Telephone fraud and long distance theft are a serious concern. The iDCS 500 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 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.
In addition any trunk or station can be programmed to ring a keyset with a predefined ring tone (1–8)
or a single line port with a predefined cadence (1–5) selection. 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 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 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.
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 local
telephone company may use E&M tie lines to provide DID service. In this case these tie lines can be
programmed to follow the DID translation table. See DID. Translated E & M tie line calls have
Time-based routing capabilities.
