The presence of micro-reflections is determined in a network by determining micro-reflections from amplifier and diplex filter impedance mismatches and micro--reflections from drop cable impedance mismatches. The micro-reflections from impedance mismatches are determined by instructing network element to transmit a test signal at a first symbol rate and a first resolution for amplifier and diplex filter impedance mismatches and a second frequency with a second symbol rate and second resolution for micro-reflections from drop cable impedance mismatches. The tests are performed with several frequencies and the channels with the least micro- reflections are identified.
