PURPOSE:To reduce the necessary capacity of a data memory storing the signaling data by utilizing one of two K pieces of storage area on the data memory based on MID information. CONSTITUTION:When an error check code is calculated about all the signaling data from terminals corresponding to one relevant MID information, an error check code matching part 12 checks the presence or absence of matching and whether the errors exist or not on the arrived signaling data. Based on the MID information allocated properly, the relevant terminal is set to utilize one among 2K pieces of storage area on the data memory 2. As this result, the data memory 2 can be sufficient, for example, with 2nK address areas in the address direction. |
