DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for the setting up of telephone calls between subscribers of a radio network and/or of a wired telephone network.
It applies in particular to the field of military radiocommunications where it enables the automatic integration of the combat radio with the existing telephone networks by making the various tactical radio means HF, VHF and VHF/UHF dependent.
In the known military radiocommunications systems, the setting up of calls between a radio network and a cabled or wired telephone network is carried out manually by an operator who sets up, by means of a connecting panel, the links between the transceivers of the radio network and the transmission lines of the wired telephone network. In addition to the fact that this mode of operation requires the operator to carry out complicated manual procedures, these systems appear antiquated and unsuitable for taking account of the rapid evolution of situations on the battlefield, in particular they do not enable the rapid routing or collection of information and do not provide any effective protection against enemy countermeasures.
The object of the invention is to overcome the abovementioned disadvantages.
For this purpose, the object of the invention is a device for the setting up and routing of telephone calls between subscribers of a radio network and/or of a wired telephone network in which the subscribers of the radio network have radio transceiver sets operating in alternating mode and the subscribers of the two networks have dialling means in order to call their correspondents, of the type comprising an automatic telephone exchange coupled with the wired telephone network by means of wired telephone lines, the automatic exchange being coupled to the radio telephone network by means of a plurality of radio transceivers via a connecting unit comprising means of detection of voice activity in order to enable the transmission of the calls in an alternating mode between the subscribers of the radio telephone network on the one hand and between the subscribers of both networks on the other hand, and means of selection sensitive to the dialling means of the subscribers of both networks in order to automatically set up telephone calls between all of the subscribers, characterized in that the means of selection comprise a plurality of programmed processing units each connected to a transceiver coupling the automatic exchange to the radio network and in that each processing unit is programmed to enable an organization of the radio subscriber network into groups of radio subscribers communicating on a same frequency and/or on a same transmission channel, the calls being able to take place between subscribers in a same group or between subscribers belonging to different groups.
An advantage of the invention is that it enables, in radiocommunication systems, a horizontal and vertical coordination to be provided between the subscribers of the radio network and those of the wired network.
On the technical side it enables, in an entirely automatic way, the setting up of calls between radio sets operating in alternating mode and wired telephone sets, the radio links being able to be encoded or not encoded at the choice of the radio subscriber.
On the functional side it provides the command with controllable and adjustable capabilities for the automatic setting up of calls, by simple dialling of users belonging to two different populations, for example the telephone subscribers of one command station with the radio correspondents of one or more combat networks.
By means of the invention, the telephone subscribers to the wired network have on the one hand, between them, all of the facilities offered by the automatic exchange, i.e. possibilities of access to external switched networks or possibilities of obtaining calls in duplex, and on the other hand the telephone subscribers of the wired network have, between them and the radio correspondents, calls set up in alternating mode in order to facilitate the transmission of orders and r
