Attenuation and noise margin query

    Attenuation and noise margin query

    Hi all,

     I've moved to a new house and despite the broadband connection taking longer than expected to transfer to the new place (many thanks to Alex in Customer Services for putting up with my frustrations after the two week mark) I am now up and running.

    Could someone in the know please offer feedback on the following values ?

    Output Power (Up/Down) [dBm]: 11.5 / 12.0
    Line Attenuation (Up/Down) [dB]: 5.0 / 6.0
    SN Margin (Up/Down) [dB]: 28.0 / 30.0

    Now to the best of my knowledge the attenuation is good, signal to noise ratio looks ok too. TBH I'd welcome any feedback on what is considered a good (and realistic) value for the SN margin. What is the deal with output power though ? It's something I've not considered in the past, and want to know how important it is, what it relates to and so on.

     Thanks in advance for your feedback.
