TH6226B - A device for linking the numeric terminal to the numerator. - Google Patents

Abstract

A device which is provided in a communication system that uses numerical signals. for use in connecting signal terminals attached with the numeric signal exchanger The signal terminal will have The transmitter (9) is for transmitting the alarm signal to all terminals (3) and also the signal exchanger (1) initially and for transmitting the data received from one terminal to the transmitter. Exchange signals and other terminals All in the second terminal, the signal has a carrier (27 , 28) for transmitting data to match the received signal. according to the specified number of times at the center of the terminal receiving the information said to adjust the transducer one more time to enter Second working condition The signal terminal has a comparator in it to determine whether the data returned from that center. Does it match the same data signal terminal? and if the data is not used The same will disconnect the signal from the link system.

Claims (5)

1. A device in a communication system that uses a numeric signal to connect a digital terminais to a terminal junction point connected to A digital exchange, characterized by a terminal complex, consists of a transducer (directing means, 9), which initially sends a flag signal to all terminals (3) ready. Which is sent to the exchanger (l) as well. This signal is used to indicate that The desired signal has not been transmitted yet, and in the next step the transmitter Wisdom sends the information received from one signal terminal to the exchanger. Also, these terminals have carriers (27, 28) that send information to match the signal. Reasons that have been received the specified number of times. Centralization The receiving terminal will set the emitter again to the second operating state, in the terminal there is a comparison medium (34) which is used to find out where the data returned from zero. Is the sum of the data being output from the same data terminal and if yes, is the same data? Will cut off the signal terminal Log out 2. Equipment according to claim 1, with the form that the center The signal terminal has a carrier (15, 17) that will transmit the information it receives from the terminal. Signals are returned to these terminals via auxiliary channels. (supplementary channel) in which these terminals have carriers (23, 24) that can receive information through that channel. 3. Equipment according to claim 1 or 2, having the characteristics that Provide a signal capture circuit (13, 56, 57, 58) for each line that These circuits will detect the data signal and as long as the signal is not present, it controls the intermediate. Transmits the signal, but the warning signal 4.A device according to any of the above claims, characterized by the presence of a terminal collector has a suitable circuit (60), which forces the transmitter (9) to send an alarm as long as the data signal from the signal terminal does not. Appears 5. A device according to any of the above claims, characterized by a terminal block, has an appropriate circuit (55), which receives a two-digit binary balues and feeds the signal Received properly, returned to the multiple terminal by Via photocopiers (9). These terminals which return a two-digit signal that is different from the one received. It will be cut off the link so that the two-digit signal of the unbroken pole will pass into the ideal circuit. Equation without interference (5 claims, 2 pages, 5 photos)
