Abstract

Method and device for telephone tapping and recording. The invention relates to a device making it possible to intercept telephone communications and to record them whatever the method of connection chosen by France-Telecom (bridge or line acquisition). This invention also makes it possible to identify the origin of the call at the start of the communication, and also allows audio and graphical marking of the various parameters transported by the line. This device consists of a box containing an electronic card controlled by various signal recognition modules, as well as an audio recording device and a printer. This device according to the invention is particularly intended for telephone tapping carried out by the authorised official services.

Description

La réalisation porte sur les procédés et dispositifs propres aux écoutes téléphoniques réalisées par les services habilités sur les lignes d'abonnés. The production relates to the methods and devices specific to telephone tapping carried out by the authorized services on the subscriber lines.

Les matériels utilisés sont généralement de deux types, soit en modules comprenant, déclencheur magnétophone, codeur et décodeur de numérotation, soit une génération déjà plus évoluée, constituée d'un appareillage compact, dans lequel est incorporé un module d'enregistrement asservi par une carte électronique permettant le marquage vocal, sur cassettes audio, de différents paramètres, dont, l'heure et les numéros composés. Tous ces appareils fonctionnent en mode "dérivation". The materials used are generally of two types, either in modules comprising, tape recorder trigger, coding and decoding numbering, or an already more advanced generation, consisting of compact apparatus, in which is incorporated a recording module controlled by a card. electronic allowing the vocal marking, on audio cassettes, of various parameters, including, the time and the numbers dialed. All these devices operate in "bypass" mode.

Les inconvénients du matériel existant sont, d'une part qu'ils ne permettent pas d'identifier les numéros de téléphone appelant et d'autre part, qu'ils ne fonctionnent qu'en mode dérivation. The disadvantages of the existing equipment are, on the one hand that they do not make it possible to identify the calling telephone numbers and on the other hand, that they only operate in bypass mode.

L'invention s'est fixée pour but de remédier à ces inconvénients en créant un ensemble compact mixte, de faible encombrement, intégrant un module d'enregistrement audio et graphique asservi par une carte électronique capable
- de tester la ligne et de se configurer en version "dérivation" ou en version prise de ligne" selon le mode choisi par France-Télécom;
- d'actionner la fonction I.A.M. de l'autocommutateur de
France-Télécom en début de communication, pour obtenir le numéro de téléphone du correspondant qui appelle.The invention has set itself the aim of remedying these drawbacks by creating a mixed compact assembly, of small footprint, integrating an audio and graphic recording module controlled by an electronic card capable
- test the line and configure itself as a "branch" version or as a line socket version, depending on the mode chosen by France-Telecom;
- activate the IAM function of the PABX
France-Télécom at the start of the call, to obtain the telephone number of the correspondent who is calling.

L'intérêt de cette innovation est évidente puisqu'elle permet, dans les affaires judiciaires importantes (rapts avec demande de rançon par exemple), d'identifier, de manière automatisée, l'origine de l'appel en début de communication.  The interest of this innovation is obvious since it allows, in important legal cases (abductions with ransom demand for example), to identify, in an automated way, the origin of the call at the beginning of communication.

Selon le procédé de l'invention
- la carte électronique teste la ligne et reconnaît automatiquement le mode de raccordement adopté par France
Télécom (dérivation ou prise de ligne) et se configure selon, permettant ainsi l'interception et l'enregistrement des communications de l'abonné surveillé.According to the method of the invention
- the electronic card tests the line and automatically recognizes the connection method adopted by France
Telecom (branch or line seizure) and is configured according to, thus allowing the interception and recording of the communications of the subscriber being monitored.

- La même carte électronique simule, en début de communication, une micro-coupure de 270 millisecondes, en générant, sur la ligne de l'abonné, une montée en tension supérieure à 48 volts. Cette simulation permet de déclencher la fonction I.A.M. de l'autocommutateur qui se croit en présence d'une micro-coupure et, ainsi, de connaître le numéro de téléphone de l'appelant. - The same electronic card simulates, at the start of communication, a micro-cut of 270 milliseconds, by generating, on the subscriber line, a rise in voltage greater than 48 volts. This simulation triggers the I.A.M. the PABX who believes that there is a micro-cutoff and, thus, to know the telephone number of the caller.

Le dispositif d'écoute et d'enregistrement téléphonique, selon l'invention, est remarquable en ce qu'il comprend, branchée sur la ligne télécom, une carte électronique de traitement de l'information asservie par un circuit de reconnaissance des numéros codés en fréquence. La dite carte électronique est apte à agir ; d'une part, sur différents modules, conformés pour détecter, la configuration de la ligne de raccordement, la sonnerie de l'appareil téléphonique, la tonalité occupée, les différences de tension sur la ligne, mais également pour simuler une micro-coupure et ; d'autre part, sur un module d'enregistrement audio de la conversation et des différentes données véhiculées sur la ligne. L'information donnée par chacun des dits modules est envoyée dans une carte informatique de traitement asservie par une horloge et d'un synthétiseur de parole. La dite carte est également assujettie à l'appareil d'enregistrement, et à une imprimante qui sur listing fournit toutes les indications, utiles à l'utilisateur, que nous avons prévues.  The telephone listening and recording device according to the invention is remarkable in that it comprises, connected to the telecom line, an electronic card for processing information controlled by a circuit for recognizing the numbers coded in frequency. Said electronic card is able to act; on the one hand, on different modules, configured to detect, the configuration of the connection line, the ringing of the telephone apparatus, the busy tone, the voltage differences on the line, but also to simulate a micro-cut and ; on the other hand, on an audio recording module of the conversation and the various data carried on the line. The information given by each of said modules is sent to a computer processing card controlled by a clock and a speech synthesizer. Said card is also subject to the recording device, and to a printer which on listing provides all the indications, useful to the user, that we have provided.
