PURPOSE:To realize the system in which the probability of disabling test is greatly lowered in the test for testing whether or not a base station is normal. CONSTITUTION:A base station (action base station) 1 conducting the test sends a test code to a base station 2 to be tested and the base station 2 to be tested receives a code, loops back it for transmission and the action base station 1 receives the test code subject to loopback transmission to check the coincident with the code sent at first. Or the action base station 1 sends a test code whose content is known to the base station 2 to be tested and the base station 2 to be tested checks whether or not the code is accurately received. |
