Abstract: PURPOSE: A method for searching a repeating signal of a small exchange is provided to prevent a loss of a resource according to an unnecessary output by outputting a repeating signal search result as much as the number of maximum output designated by an operator when performing a repeating signal search function having a R2/NO.7 signal method. CONSTITUTION: If a register command of a repeating signal search function having a R2/NO.7 signal method is inputted from an operator, a CTPM identifies as to whether a function register to an inputted resource is performed and transmits a function performing start request to a CTPS when the inputted resource is performed. The CTPS receives the function performing start request and performs a child process for performing a function. If a search function to an occupied repeating call resource is identified to perform the search function to a registered resource and the performed result is informed to a repeating call processing unit(TKC/TPC), the CTPM accesses a database for managing register information of a R2/NO.7 repeating signal search function, compares the number of performance of a current search function with the number of a maximum performance set by the operator.
