[c-nsp] cisco show Interface transceiver detail

[Tony]

Hi,

I think it tells you in the description what they both are:

"A2D readouts (if they differ), are reported in parentheses."


DOM = Digital optical monitoring
A2D = Analogue to digital


Without thinking too much about it I suppose that the digital signal and analog signal could differ if there is some loss in the quality of the signal (so D2A has more issues recognising a "0" or "1"). Optics isn't really my field so I'm speculating, someone else might have a better answer on that.


regards,
Tony.
