Re: Best ADSL modem for long line?


[re: radiomarko] [link to this post]
 
Oh dear frown. The old one we had to ask lots of people next to railway lines, and in particular if they were close to level crossings.

LED street lights will inevitably spread.

My broadband basic info/help site - www.robertos.me.uk. Domains, site and mail hosting - Tsohost.
Connection - AAISP Home::1 80/20. Sync 63086/13719Kbps @ 600m. BQMs - IPv4 & IPv6

In reply to a post by dewi:
The line didn't drop last night. I'll continue to monitor.


Monitoring with RouterStats-Lite I found useful - I was able to easily show the visiting OR SFI engineer the pattern of noise bursts causing a sudden downstream SNRM fall from 6dB to 0dB and the subsequent resync.

Best of luck.

Just watch tonight and see when teh lights go on! LED lights are known to give very high levels of RFI.

Keep checking the status page for sync speed and take screen shots ... Include the little bit loading graph at the bottom too.

The 2700HGV hasn't lost connection since Zen forced interleaving on last Wednesday, meaning that it remains connected at 2777 kbps. I'm very happy with that, as it's towards the upper end of the line speeds I was seeing with the Billion 7800N.

The noise margin is about 14.5 to 15.5 dB during the day, dropping to 5.5 dB every night.
