DESCRIPTION
"This attribute indicates the measurement offset that the ONT should use in
AGC. The attribute has a step size of 0.1 dB, represented as a signed integer.
The theoretical nominal RF signal is 80 channels of NTSC video, each
having a per-channel optical modulation index of 3.5%. An ONT
presented with such a signal should produce its specified ou
tput when this attribute is set to zero.
If total optical power is used for AGC, this attribute provides the OMI
offset for any NTSC carriers present from the theoretical 3.5% value. For
example, if the actual signal uses an OMI of 7.0% per channel (3 dB
higher), then the ONT should be given an AGC setting of 30
(coded 0x1E).
If broadband RF power is used for AGC, this attribute provides the total
power offset for any NTSC carriers present from the theoretical 80 channel
value. For example, if an actual signal contains 40 NTSC channels (3 dB
lower), then the ONT should be given an AGC setting of <0096>30 (coded
0xE2)."
