| Module | ADSL2-LINE-MIB (CISCO) |
| Nom | adsl2SCStatusQln |
| Acces | readonly |
| Status | current |
| Description | An array of up to 512 real Quiet Line Noise values in dBm/Hz
for the respective transmission direction. It is designed for
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 QLN(f = i*Df) value for a
particular sub-carrier index i, (0 <= i < NSC).
The QLN(f) is represented as ( -23-n(i)/2), with n(i) in the
range 0 to 254. A special value n(i)=255 indicates that no
measurement could be done for the subcarrier because it is out
of the passband or that the noise PSD is out of range to be
represented.
This parameter is applicable in loop diagnostic procedure and
initialization. Each value in this array is 8 bits wide. |
