Question: on the CRC and FEC const vs time graphs, what are the units on the vertical
y axis? I have modem #4 running very very slowly, with a lot of noise and the downstream CRC count is high compared to the other modems. The CRC rate figure shown on the y axis is the count CRC of corrected errors[
?] per unit
what time[?]
It is a still a new performance nightmare at the moment. The downstream SNRM was 2.5 dB and I forced a resync which brought the d/s SNRM up to 3.1dB. The downstream rate is even slower now, with a downstream sync rate below 2.5Mbps, whereas it was ~2.9 Mbps before, and in total I have lost about 0.8-1.0Mbps total effective download rate from speed tests with speedtester2.aa.net.uk compared to what it was like a couple of months ago.
Live sync rates:
#1: down 2807 kbps, up 519 kbps
#2: down 2700 kbps, up 544 kbps
#3: down 2964 kbps, up 389 kbps
#4: down
2457 kbps, up 515 kbps
