Изобретение относится к связи и, в частности к устройствам дополнительных услуг АТС. Цель изобретения - представление абоненту дополнительных услуг, например рекламных сообщений, во время ожидания ответного сигнала от вызываемого абонента. Для этого дополнительная информация вводится в линию абонента, набравшего номер и ожидающего ответа в четырехсекундные паузы между звонками, т.е. сигналами контроля посылки вызова до момента снятия вызываемым абонентом трубки телефона. Устройство содержит трансформатор, включенный в линию, и логическую схему различения длительности импульсов, состоящей из логического элемента И - НЕ и блока формирования секундного импульса, т.е. равного длительности сигнала контроля посылки вызова. Электрический мост преобразует сигнал частотой в 450 Гц в импульс прямоугольной формы, длительность которого сравнивается с импульсом преобразователя, и при их совпадении включается магнитофон или ПЗУ на четыре секунды, т.е. на время паузы между звонками для передачи в линию сообщения.The invention relates to communication and, in particular, to devices for additional services of PBX. The purpose of the invention is to provide the subscriber additional services, such as advertising messages, while waiting for a response signal from the called subscriber. For this, additional information is entered into the line of the subscriber who dialed the number and waits for a response in four-second pauses between calls, i.e. call control signals until the called party picks up the telephone handset. The device contains a transformer included in the line, and a logic circuit for distinguishing the duration of the pulses, consisting of the logical element AND - NOT and the unit of formation of the second pulse, i.e. equal to the duration of the call control signal. The electric bridge converts the signal with a frequency of 450 Hz into a rectangular pulse, the duration of which is compared with the pulse of the converter, and if they coincide, the tape recorder or ROM is switched on for four seconds, i.e. during a pause between calls to send a message to the line.
