PURPOSE:To execute switching control between TDMA data and TDM data by storing the TDMA data in data memory, storing output pattern data from the grounding in an output pattern memory, reading the output pattern data, making the read output pattern data into a read address, and reading the contents of the data memory as the TDM data. CONSTITUTION:A write address generating circuit 11 gives a write address 5 to a data memory 9 and writes the input baseband TDMA data to the data memory 9. An output pattern write address generating circuit 14 of a read address generating circuit 12 gives a write address 16 to an output pattern memory 13 and writes output pattern data 7 to be sent from the ground to the output pattern memory 13. An output pattern read address generating circuit 15 gives a read address 17 to the output pattern memory 13, reads the contents of the output pattern memory 13, gives the read contents to the data memory 9 as a read address 6, and reads the TDM data. The TDMA data can be converted into the TDM data having a different format from that of the TDMA data by above-mentioned operations. |
