2.1 INTRODUCTION
For a better comprehension, please read the following short explanation on how the Videophone-Box works:
The Videophone-Box is only used to convert the analogue signals of the intercom system to network-capable
signals, so that the VoIP server can handle the signals. In order that the individual clients can communicate among
each other and with the video intercom, all must register on the same VoIP server.
The analogue a/b telephone signal is converted into an international VoIP-Standard, through which the VoIP server
can create communication with the intercom system. The analogue video signal is converted into a network video
stream by the Videophone-Box, which can be shown at any time from the Videophone software. The software
combines the audio and video signals, what makes possible visual communication with the person who is ringing
at the door.
As soon as the button on the external unit is pressed, a corresponding dial module or a/b transformer module
which is connected to the Videophone-Box over a telephone cable, dials out a number. The Videophone-Box
recognizes this number and makes a connection to the PC with the active VoIP server over the network. The VoIP
server executes the actions which were defined for the number dialled by the a/b transformer module; normally,
a connection to several clients is established. As soon as the connection to the clients is up, the Videophone
software appears automatically on the client PCs, showing the video signal of the external unit and emitting the
ringtone over the built-in loudspeaker.
So there is an acoustic signalization whenever anybody rings at the door and additionally the video window shows
who the person in front of the door is and what it is doing.
By clicking on the "Accept" button, the call will be activated and the audio communication between the client and
the external unit of the intercom system will be established. For establishing this communication so-called DTMF
tones are transmitted to the intercom system. In the same way, but with different DTMF tone sequences, the
door opener or the door light can be controlled. Also, the connection can be terminated by the Videophone
software by clicking on the related button of the frontend.
In few words the Videophone-Box can be seen as interface between client PCs with Videophone software
(network) and intercom systems (analogue signals).
Furthermore, the Videophone software enables calls among the single clients (Interphone function).
2.2 WIRING
As already mentioned, the Videophone-Box is divided in 2 parts:
Audio: A VoIP gateway converts the analogue a/b signal from the intercom system into standard VoIP packages.
The required connections are the following:
