<p>A method and apparatus for using a loopback capability of a radio frequency (RF) repeater (120) to provide for end-to-end testing without a wireline connection is disclosed. A RF source (110) sends a signalling waveform to the RF repeater (120). Upon receiving the signalling waveform, the RF repeater (120) enters the loopback mode. The RF source (110) sends another identical signalling waveform to the RF repeater (120) to end the loopback mode. In another embodiment, a base transceiver station BTS (310) sends a signalling waveform to an intelligent RF repeater-translator (320) upon detection of a lack of activity. The received signalling waveform places the intelligent RF repeater-translator (320) into a loopback mode. If alarms are present in the intelligent RF repeater-translator (320), the intelligent RF repeater-translator (320) ceases processing and the BTS (310) informs the OMC of the error condition. Otherwise, the loopback mode is entered and BTS (310) initiates testing of the intelligent RF repeater-translator (320). The loopback mode is discontinued when the intelligent RF repeater-translator (320) receives another identical signalling waveform or after a time-out period elapses. The intelligent RF repeater-translator (320) has the capability to alternate the selected diversity uplink path from one loopback test to the next loopback test to ensure full testing of all RF paths.</p> |
