Item Description
Get
Press ‘Get’ button to get the DSL bin information, then press others button to show.
Upstream Bin Bits
Number of downstream bits/ bin for the bin indexed by this element of the string. The
0th element contains the number of bits per bin for 0, through the 31st element, which
contains the number bits for bin 31. (upstream)
Upstream Bin SNR
The DELT-related parameter that provides an array of real downstream SNR (f) values
in dB (Not available for ADSL and ADSL2plus)
Downstream Bin Bits
Number of upstream bits/ bin for the bin indexed by this element of the string. The 0th
element contains the number of bits per bin for 0, through the 31st element, which
contains the number bits for bin 31. (Downstream)
Downstream Bin SNR
