There will be something very useful to be gained from thinking carefully about the three numbers, not just the scale of the numbers in general. If we take a look at the ratio ReXmtCorr / ReXmt, I presume that that tells us how much we are struggling with serious badness because we are having to do multiple retransmissions, so either the interleave is not working or we need to get some, or we are getting really really long period blips ( interleave confuses matters completely so this has to be looked at after mentally reversing the interleave ) or full-on outages. Is that correct?
Some intelligent software in a modem could use this to advantage - a sign that the FEC levels need to be put up if the ratio is not too high, but if it is then it is a sign that we desperately need a ton more interleave depth. Is that right?
How would we decide on what to set the DTU size to be? Setting it too small is undesirable because it is bloatful, inefficient in terms of added overhead bytes.
