Re: RFC3728 (1788) (RFC Errata System)

Hi,



When I look at the corresponding objects as defined in the ITU-T G997.1:



Section 7.5.1.13 Downstream Signal-to-Noise Ratio Margin (SNRMds)

The downstream signal-to-noise ratio margin is the maximum increase in dB of the noise power received at the xTU-R, such that the BER requirements are met for all downstream bearer channels. The downstream SNR margin ranges from -64 dB to +63 dB with 0.1 dB steps. A special value indicates the parameter is out of range to be represented.



So this seems to indicate that dB would be the correct units.



Best Regards,

Menachem

There are several ways to mark an errata request.



Verified - practically meaning accepted as proposed

Rejected

Held for Document Update



In this case a change in semantics cannot be just accepted as proposed,

as the accepted method to change semantics of an object is according to

the SMI rules by deprecating the old object and defining a new one.



We need however to get consensus in the WG on what is the right solution

from a technical point of view.
