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. Apparatus for performing interesting continuity tests of the two-son analog lines connected to a time division multiplex switching network by a hybrid circuit. </P><P>Un émetteur à fréquence vocale S et un récepteur à fréquence vocale E sont connectés à une liaison à multiplexage temporel ZS. </ P> <P> A voice frequency transmitter S and a voice frequency receiver E are connected to a ZS time division multiplex link. 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. The test signals sent by the transmitter on the reception time slot tx of the line to be tested through the hybrid circuit G, and return by the temporal transmission channel of this line ty to the receiver which evaluates them. L'invention est applicable dans les systèmes de télécommunications pour effectuer des tests à l'établissement des communications ou des essais systématiques. The invention is applicable in telecommunications systems for testing to establish communications or systematic testing.
