摘要: A system and method are disclosed to implement fault detection in DSL loop extenders. The of the invention includes a plurality extenders coupled local loop, extender (LE) test box circuitry each LE sends tone pair associated with over processes generate response via loop. Then, determines functionality based upon received tone.
