| Module | ADSL2-LINE-MIB (CISCO) |
| Nom | adsl2SCStatusLinImg |
| Acces | readonly |
| Status | current |
| Description | An array of up to 512 complex H(f) linear representation
values in linear scale for the respective transmission
direction. It is designed to support up to 512 (downstream)
sub-carriers.
The number of utilized values on downstream direction depends
on NSCds, and on upstream direction it depends on NSCus. This
value is referred to here as NSC.
Each array entry represents the imaginary component [referred
to here as b(i)] of Hlin(f = i*Df) value for a particular sub-
carrier index i (0 <= i < NSC).
Hlin(f) is represented as ((scale/2^15)*((a(i)+j*b(i))/2^15)),
where scale is Adsl2SubcarrierLinScale and a(i) [provided by
the Adsl2SubcarrierLinReal object] and b(i) are in the range
(-2^15+1) to (+2^15-1).
A special value a(i)=b(i)= -2^15 indicates that no measurement
could be done for the subcarrier because it is out of the
passband or that the attenuation is out of range to be
represented. This parameter is only available after a loop
diagnostic procedure.
Each value in this array is 16 bits wide and is stored in big
endian format. |
