    Jah ezt elfelejtettem elinkelni a temaval kapcsolatban.

    SNR (Signal to Noise Ratio)

    * 6bB. or below = Bad and will experience no line synchronisation and frequent disconnections
    * 7dB-10dB. = Fair but does not leave much room for variances in conditions.
    * 11dB-20dB. = Good with little or no disconnection problems
    * 20dB-28dB. = Excellent
    * 29dB. or above = Outstanding

    Line Attenuation

    * 20bB. and below = Outstanding
    * 20dB-30dB. = Excellent
    * 30dB-40dB. = Very Good
    * 40dB-50dB. = Good
    * 50dB-60dB. = Poor and may experience connectivity issues
    * 60dB. and above = Bad and will experience connectivity issues

    Line attenuation also affects your speed.

    * 75 dB+: Out of range for broadband
    * 60-75 dB: max speed up to 512kbps
    * 43-60dB: max speed up to 1Mbps
    * 0-42dB: speed up to 2Mbps+
