Embodiment Construction

[0031] The technical solutions and beneficial effects of the method of the present invention will be made obvious by detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0032] The essence of digital exchange is the movement of the time slot content in the time position, that is, the time slot exchange. The time slot exchange is generally completed by random access memory, in which the data register is driven by the clock, and the transmitted data is written one time slot after the time slot. , Its readout is controlled by the control register, that is, under the cooperation of the control register to provide the readout address, the data register reads out the content of the relevant unit and sends it to the serial conversion circuit to realize the time slot exchange function. The control register and data register are driven by the clock, so they are very sensitive to the change of the clock. In actual use, i...

Abstract

The invention relates to a method for checking digit circuit exchanger, used to check the accidence of exchange chip and solving problem, wherein said method comprises that: timely checking the control information of control register; if the control information is damaged, rewriting right control information; if the control information is right, but the exchange chip can not work normally, timely checking the connect function of chip; if the connect function is damaged, repairing the exchange chip. The invention can improve the stability, anti-impact ability and maintenance of device.

Description

Technical field [0001] The invention relates to the technical field of digital circuit switching equipment, in particular to a method for troubleshooting digital circuit switching equipment. Background technique [0002] The history of human communication has gone from manual switching, electronic switching, program-controlled digital switching to optical transmission. The application of circuit switching in digital switching still occupies an important position in the current communication industry, such as program-controlled digital switches and GSM mobile communications. The essence of digital exchange is time slot exchange, which is to periodically transmit data on a fixed time slot on the PCM (Pulse Code Modulation) multiplexing line. To realize such exchange, digital circuit exchange is used. The chip, which consists of two parts, data register and control register, completes the data exchange function together. The control register controls the writing and reading of the d...
