The figures in the left column (downstream) reset to zero after my modem reboots. The right hand figures (upstream) never reset, I think someone said before that they are the stats from the cabinet end modem. I say never reset, maybe they reset if the cabinet looses power, or on some other event at the cabinet?
So on the downstream, I currently have 3 ES in the last 160 hours (so almost a week), which doesn't sound bad at all? The upstream ES of 17,149 is over a much longer period (possibly since my initial fttc commissioning date, which is about 15 months ago). The difference between the u/s ES figures in the two screen caps is 444, which equates to approx the last week as well. Is that excessive? Best case, assuming the total is over 15 months, that's about 40/day or 250/week, but obviously I've no idea what the spread is - it could have been perfect some days and terrible others, but it's definitely higher than downstream E/S.
What could be causing the differnce between u/s and d/s ES, presumably getting too close to the noise margin? And why am I ending up with interleaving being applied to the downstream while the upstream stays on fastpath? It looks to me like the cab modem is looking at the stats for the upstream side and deciding to apply interleaving to the downstream??
Is my modem or the cabinet modem to blame for this? It's almost like a basic compatibility issue?
I can control the SNR margin target on the d/s, but don't think I can influence the u/s snr?
I'd stuck with the Draytek over a HG612 modem to match the Lantiq chipset of my ECI cabinet. I thought that would be more beneficial than the extra stats logging available with the HG612. But maybe not?
