<p>The present invention provides a passive optical network terminal, system and method for testing subscriber lines. The terminal includes a subscriber line interface module, driving module, resource management module and Digital Signal Processing (DSP) module, which are connected sequentially. The subscriber line interface module is set to supply an analog interface; the subscriber line driving module is set to drive the corresponding hardware of the subscriber line through the analog interface, and to output the detected subscriber line status to the subscriber line resource management module; under the control of the Soft Switch (SS), the subscriber line resource management module is set to establish or release a media channel to the media server based on the subscriber line status, and to output the test service prompt phonetic packet transferred from the media server to the DSP module, and to upload the test command packet packed by the DSP module to the SS; the DSP module is set to unpack the test service prompt phonetic packet, and to output to the subscriber telephone to play, and to pack the detected test command selected by the subscriber telephone to output to the subscriber line resource management module.</p> |
