Abstract

Dispositif permettant d'effectuer des tests de continuité intéressant des lignes analogiques deux-fils connectées à un réseau de commutation à multiplexage temporel par un circuit hybride. Un émetteur à fréquence vocale S et un récepteur à fréquence vocale E sont connectés à une liaison à multiplexage temporel ZS. Les signaux de test envoyés par l'émetteur sur la voie temporelle de réception tx de la ligne à tester traversent son circuit hybride G et reviennent par la voie temporelle d'émission de cette ligne ty jusqu'au récepteur qui les évalue. L'invention est applicable dans les systèmes de télécommunications pour effectuer des tests à l'établissement des communications ou des essais systématiques.Device for carrying out continuity tests involving two-wire analog lines connected to a time division multiplexing switching network by a hybrid circuit. A voice frequency transmitter S and a voice frequency receiver E are connected to a time division multiplexing link ZS. The test signals sent by the transmitter on the reception time channel tx of the line to be tested pass through its hybrid circuit G and return via the transmission time channel of this line ty to the receiver which evaluates them. The invention is applicable in telecommunications systems for carrying out tests at the establishment of communications or systematic tests.
