SYSTEM FOR TESTING AND CONTROLLING OF AUTOMATIC SYSTEMS USING TELEPHONE NETWORKS Russian patent published in 1998 - IPC

FIELD: telephone communications. SUBSTANCE: device has first and second automatic controlled objects which are connected to each other through serial circuit of automatic phone exchange stations. Said first and second automatic objects have first and second phone sets, first and second control units, first and second continuous monitoring circuits, first and second keyboard equivalent units, first and second decoders, first and second receivers of telephone codes. In addition first automatic controlled object has first indication unit, while second automatic object has first and second call ring unit, first detectors unit and first unit of actuators. Goal of invention is achieved by first and second commutators, first and second transmitters, first and second software-control interrupters, first and second call acknowledgment units introduced to first and second automatic control objects respectively. In addition first automatic control object has second call ring unit, second detectors unit and second actuators unit. Second automatic control object has second indication unit. Group control of automatic controlled objects is achieved by use of call detection phone set by dispatcher. EFFECT: automatic transmission of error message between arbitrary automatic controlled objects, transmission of request and control commands from arbitrary phone sets which are located both inside controlled objects and outside. 2 cl, 4 dwg
