ンネル試験が行われる。 A conventional wireless channel testing method will be explained with reference to FIG. When a maintenance person gives a test instruction using the test stand 47, the central processing unit 45 selects the trunk 41 connected to the audio repeater 22 corresponding to the wireless channel under test, controls the time division switch 42, and selects the trunk 41 connected to the test trunk 48. Connecting. Further, a test order by a maintenance person is sent to the control device 25 via the line control device 44, and the test device 24 is activated. Then, the test sound is transmitted from the test device 24 to the test radio device 2.
It is sent out via 3. Note that the test radio device 23 is instructed and tuned to the frequency of the wireless channel to be tested via the test device 24.

ように補正していた。 The above is a conventional wireless channel test, in which the test trunk 48 of the master station and the test device 24 of the remote station are each equipped with an oscillator and a level measuring device. However, in this method, when a plurality of remote stations are installed, the distance between the master station and the remote station differs for each remote station, so the call loss on the line 3 will differ for each remote station. In this case, a normal level cannot be determined unless the level value of the test sound measured by the test trunk 48 and the test device 24 is corrected according to the distance between the master station and each remote station. For this reason, in conventional car telephone exchanges, an amplifier is installed in the voice repeater 22 of the remote station or the trunk 41 of the master station to compensate for the call loss on the line 3 so that it is equal for all remote stations.
