Embodiment Construction
[0030] The technical solution and beneficial effects of the method of the present invention will be apparent through the detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.
[0031] The essence of digital exchange is the movement of the time slot content in the time position, that is, 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 incoming data is written in one time slot after another. , its readout is controlled by the control register, that is, with the cooperation of the readout address provided by the control register, the data register reads out the content of the relevant unit and sends it to the string conversion circuit to realize the time slot exchange function. Both the control register and the data register are driven by the clock, so they are very sensitive to the change of the clock. In the actual u...

The invention discloses a troubleshooting method for digital circuit switching equipment, which is used for fault detection and corresponding troubleshooting processing for switching chips in the circuit switching equipment. First, the control information in the control register is regularly detected; if the control information is damaged, the Then re-write the correct control information; if the control information is correct but the switch chip still cannot work normally, then regularly detect the connection function of the chip; if the connection function of the chip is damaged, perform self-healing processing on the switch chip. The troubleshooting method of the present invention solves the problem that the digital circuit switching equipment cannot be automatically restored due to the abnormal business and communication caused by the soft failure of the digital switching circuit, and improves the stability, impact resistance and system maintainability of the equipment.
Description
technical field [0001] The invention relates to the technical field of digital circuit switching equipment, in particular to a troubleshooting method for digital circuit switching equipment. Background technique [0002] The history of human communication has gone through manual switching, electronic switching, program-controlled digital switching, and optical transmission. Among them, 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 switching is time slot switching, which is to periodically transmit data on a fixed time slot on a PCM (Pulse Code Modulation, pulse code modulation) multiplexing line. To achieve such switching, digital circuit switching is required. The chip, which consists of two parts, the data register and the control register, jointly completes the data exchange function. The...
