    bs/dlprofile - Down Link Profile

    Service that is used to specify down link adaptive modulation profile. Adaptive modulation is used to adjust signal modulation scheme and FEC coding depending on the RF link's SNR and is define in the form of list of allowed modulation and coding scheme (MCS) elements. The profile has 12 elements which are specified with the following service:

    <service name="bs/dlprofile">

    bs/ulprofile - Up Link Profile

    Adaptive modulation is used to adjust signal modulation scheme and FEC coding depending on the RF link's SNR. The best modulation scheme is selected from the list of available up link profiles: ulprofX where X = [1,10]
