摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to the technical field of the tactical exchanger.;2. The technical problem to be solved by the invention;The present invention provides a subscriber focused three-stage tactics exchanger having excellent mobility and operability in a tactical environment.;3. Summary of Solution to Invention;The present invention provides a subscriber intensive type tactical switch comprising: a power supply unit (10) for supplying power, including a first power supply unit, a second power supply unit, and a ring power supply unit, and a plurality of control functions to perform overall operation and control of the system A central processing unit (20), a switching unit (30) connected to the central processing unit (20), and performing a function for exchanging a subscriber and equipment bidirectional multiple lines of ten lines, and the switching unit (30) A clock and front panel connection unit 40 which is connected to generate a main clock signal and performs a signal supply function for operation of the system, and is connected to the switching unit 30 to remotely access information of a plurality of channels according to an operation mode. A multi-line connection unit 50 for transmitting a signal, a subscriber signal connection unit 60 connected to the switching unit 30 to perform a common connection control function for subscribers of ten lines, and the subscriber signal contact An analog subscriber connection unit 70 connected to the sub-unit 60 to perform a function of coding a voice signal into a digital signal, and a subscriber terminal connected to the subscriber signal connection unit 60 to transmit a digital terminal in echo cancellation and to process a signal. The digital subscriber access unit 80, which performs the function of accessing the switching unit 30, is connected to the analog subscriber connection unit 70 and the digital subscriber connection unit 80 to connect the subscribers of the ten lines of the two-wire system to provide overvoltage and overcurrent. And a terminal connection part 90 that performs a function of preventing and a mating line part 100 that is connected to the multi-line connection part 50 and performs a function for providing a communication means during a normal operation or initial installation. .;4. Important uses of the invention;The present invention is suitably used in an exchanger.
