The data provided in the Advanced ADSL Information window includes: ♦ Re_training - number of attempts to establish the ADSL connection ♦ CRC - Cyclic Redundancy Checking, number of CRC errors since ADSL connection established ♦ FEC - Forward Error Correction, number of FEC errors since ADSL connection established ♦ HEC - Header Error Checking, number of HEC errors since ADSL connection established ♦ Line Attenuation - measured in dB ♦ Noise Margin - measured in dB ♦ Output Power - measured in dBm The Carrier Information menu displays the frequency distribution of the upstream and downstream bandwidth. The upstream portion occupies the lower frequency block. 19
