FEC errors


[link to this post]
 
This is a current log from my speedtouch585. I used to get this at one time but things improved. I assume that all the wet and cold has had a poor effect on my line.
Over a billion FEC errors is a mite corncerning.

Uptime: 7 days, 17:49:40
Modulation: G.992.1 annex A
Bandwidth (Up/Down) [kbps/kbps]: 448 / 7,488
Data Transferred (Sent/Received) [MB/GB]: 340.05 / 3.20
Output Power (Up/Down) [dBm]: 12.0 / 19.5
Line Attenuation (Up/Down) [dB]: 20.5 / 37.0
SN Margin (Up/Down) [dB]: 22.0 / 7.0
Vendor ID (Local/Remote): TMMB / TSTC
Loss of Framing (Local/Remote): 0 / 0
Loss of Signal (Local/Remote): 0 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): 0
Error Seconds (Local/Remote): 171 / 0
FEC Errors (Up/Down): 0 / 1,057,115,751
CRC Errors (Up/Down): 0 / 11,827
HEC Errors (Up/Down): 0 / 11,587

Thomson Speedtouch routers are infamous for their huge FEC error count. Don't worry about it.

Home ADSL: Be Unlimited LLU
Business ADSL:
Be LLU supplied by Andrews & Arnold
Orange 3G Business Everywhere Mobile BB

As above, as long as you are not getting any speed issued etc, I wouldn't worry about it.

o2 LLU
ROUTER:-DGN2000
Sync 17848D 1412U Annex A
Att:-35.0dB Down 17.4dB Up
SNR:-1.5dB Down 3.1dB Up

FEC errors are corrected errors, the errors are caused by noise on your line. This noise also reduces your sync speed.

Thanks all, I'm not overly worried except that I was wondering if its a symptom of a deteriorating line due to weather etc.

Are you familiar with how your stats normally look?
For me, I would be more worried about the reported Error Seconds!

If you monitor your stats regularly then you'll get a feel for when things are going pear shaped! As the router has been connected for a week it's not obvious to see what's been going on. I can recommend RouterStats free s/w to monitor things. I have the same router as you and it works great smile

From memory I only get the odd one or two allied with about a million fec errors. Normally I only get about 20 days before it resets. Speed still reasonable all things considered but fluctuates quite a lot.

On reflection it could also be congestion.
