    Default Relation between download speed & Attainable Rate (Kbps) in modem statistics

    Can anyone please tell me how download speed depends on the Attainable Rate (Kbps) & rate (shown in the modem stats):
    For me it is:


    Mode: ADSL2
    Line Coding: Trellis On
    Status: No Defect
    Link Power State: L0

    Downstream Upstream
    SNR Margin (dB): 3.0 4.4
    Attenuation (dB): 50.0 31.3
    Output Power (dBm): 12.9 0.0
    Attainable Rate (Kbps): 1708 792
    Rate (Kbps): 1517 856

    And while downloading with bittorrent i get speed about 130 kBps.

    Attainable rate is actually the line rate set in the DSLAM at exchange(by default 2 Mbps).It is the maximum possible rate you can receive.
    The d/l speed for every plan is the data transfer rate which is completely different from the attainable rate.Although it matters when the attainable rate is less than the d/l speed.Suppose, in your case the attainable rate is 1708 Kbps and you want to take a 4 Mbps(4096Kbps) plan then you will get a maximum of 1.67 Mbps speed but not more than that.
