Re: DLM and the NTE Modem


[re: Alexir] [link to this post]
 
I need to spend more time going through the numbers, but for now... Wow - what a difference to the previous stats! shocked

Are you graphing the errors (the CRC preferably, but FEC would be good too)?

It'd be worth doing that for the next burst of P2P work...

Speed returned to normal now, no idea if it was due to the heavy P2P or not. System uptime at 20 days shows the modem has been on constantly since I flashed the hack but DSL uptime is only 1 day again, so why would I be getting disconnected every so often?

These two statements...
In reply to a post by Alexir:
Speed returned to normal now
<snip>
DSL uptime is only 1 day again

are connected...

If DLM intervened to change settings - to set them higher or lower, or to remove them at all - then the modems will need to resync, and the "link time" will start again. And the speed you experience will change.

If you can count back "1 day 7 hours" from when you took the stats, and find that it is in the middle of the night (perhaps between 2am and 7am), then this re-enforces the likelihood.

Anyway, now it is all working, you need to monitor the error rates, to see what they look like without P2P running.

You can do this manually, by grabbing the output from "--stats" every 24 hours would be good, to see the changes in the "latest 1 day" and "previous 1 day" entries.

BaldEagle's stats package could be used instead, to grab the information every minute. That way you get the figures graphed.

After getting some averages from that for a few days, it'll be time to fire up the P2P for a while, and start grabbing stats every 15 minutes, or watching the graphs.
