PURPOSE:To conduct a position registration test, an incoming outgoing call test and a speech channel changeover test or the like between base stations by sending a control signal designating the azimuth of a directivity antenna of the transceiver placed on a mobile body from a test board of a radio exchange. CONSTITUTION:A signal commanding the azimuth of a directivity antenna (ANTTR) of a transceiver sent from a test board 13 via an exchange 12 is converted by a control section (TTR-CL) 10 into a control variable of an antenna azimuth change device (DA-CTL) 2 to change the direction of the antenna ANTTR. Moreover, the control section TTR-CL 10 sends a signal received by a receiver 4 to the test board 13 via the exchange 12. When the directivity of the antenna ANTTR is directed to a station A and the test transceiver is in non-talking state and a power supply is turned on, the test transceiver is registered to the station A by a registration signal. The transmission level of a broadcast channel of the station A is monitored by the test board 13 as a reception level of the test transceiver. The similar test is conducted to base stations B, C. |
