Matrix ETERNITY NE System Manual 589
The ETERNITY connects the Door Phone to the Trunk Port on the basis of the Outgoing Trunk(s)
assigned for the external number. When connected to the Trunk Port, the Door Phone receives Call
Progress Tones of the CO Network.
• When the external number answers the call, speech is established between the visitor and the external
number.
• The called party on the external number ascertains the identity of the visitor.
• To open the door from the remote location,
• the called party on the external number puts the visitor on hold by dialing '#2'. The system plays music-
on-hold to the visitor.
• the called party on the external number dials the Feature Access Code for 'Open the Door' (default:
1173)
51
.
• the Door Lock is opened for the duration of the Timer 'Open Door for’, (default: 5 seconds)
52,53
.
• as soon as this Access Code is dialed, speech is reestablished with the visitor.
• the visitor is invited to enter the building.
• the called party on the external number disconnects the call
54
; the Door Phone goes idle.
This way, it becomes possible to answer the door bell call from a remote location and open the door lock
from the remote location.
• The Door Lock can be opened by the called party on the external number also by dialing the command
for operating the DOP to which the Door Lock is connected, instead of dialing the 'Open the Door'
access code. Refer the topic “Digital Output Port (DOP)” for operation instructions.
• The called party on the external number can also call the Door Phone using Direct Inward System
Access (DISA).
• It is also possible for the called party on the external number to make multiple calls, while putting the
visitor at the Door Phone on hold. For this, the party must be logged in the “Direct Inward System
Access (DISA)” mode.
• The Door Phone feature of the ETERNITY NE offers the flexibility of selecting the Routing Mode for Door
Phone calls. The system supports two Door Phone Call Routing Modes:
• At Wish: Whenever you want to route the Door Phone Calls, you can alternately select the landing
destination, i.e., select a group of extensions at one time, an external number (the programmed fixed
line or mobile number) the next time, as required. The extension user can change the Call Routing
Mode, i.e. the landing extension or external number, as and when required.
• Scheduled: You can program the system to route Door Phone Calls automatically to the landing
destination phone according to the time of the day: Day (working hours) or Night (non-working hours).
For example, you can have Door Phone calls during the Day landed on the extension(s) of the
ETERNITY NE, and Door Phone calls during the Night on an external number. It is also possible to
assign different groups of extensions for Day and Night time.
51. This access code is to be dialed only when in speech with the visitor. If this access code is dialed when there is no speech, an error
tone will be played to the extension user for the duration of the Error Tone Timer.
52. This is the time for which the door will remain open.
53. An error tone will be played to the extension user for the duration of the error tone timer, if a DOP has not been assigned to the
Door phone port.
54. If the trunk used for placing this call is a Two-Wire Trunk, dial #0 to disconnect the call.
