A mobile station comprises means (301, 302, 303, 304, 326) for receiving downlink data from test equipment and means (331, 310, 311, 312, 313) for sending uplink data to the test equipment. To test data channel operation a test loop (204, 332, 333) is established to loop downlink data received from the test equipment back to the uplink direction to the test equipment. During the test, the reception of downlink data and transmission of uplink data in the mobile station are controlled by a relatively low protocol level. |
