A connection adapter includes first interfaces, second interfaces for connection to communication devices connected to a radio packet communication network, and a conversion circuit performing mutual conversion between an input/output signal from or to high-level equipment and an input/output signal from or to the communication device. The conversion circuit receives or supplies from or to the high-level equipment a signal simulating the communication device connectable to the high-level equipment and receives or supplies from or to the communication device a signal simulating the high-level equipment connectable to the communication device.
