MAINTENANCE SYSTEM FOR SWITCHING CENTER

摘要

inputting a key from a maintenance terminal to analyze whether the inputted key is a deletion key; terminating the operation upon finding that the inputted key is not a deletion key; terminating the operation upon finding that the inputted key is "0" when the inputted key is a deletion key; terminating the operation upon finding that the value of the current position and the value of the number of the inputted keys are equal to each other; setting "I" as the value of the current position; moving the I + 1th key to the Ith position to output the Ith key; terminating the operation upon completion of N times of the implementations of the preceding step; outputting the backspace N + 1 times.
