Hi newport258 & Welcome to the Kitz forum.
Hi,
Just had BT Infinity 2 installed on a brand new phone line, BT estimated 56 down and 20 up
Not fantastic, so possibly not too close to the cabinet (or the first in the area to be connected and/or new phone line so no historical data)?
In reality i have the following stats:
Attainable rate: 50044 down 16368 up
SNR margin: 9.8 down 9.6 up
Line att: 0 down 0 up
Output power: 12.8 down 6.3 up
Actual Line rate: 39999 down 10000 up
Here are my questions
1, Why is my actual profile stuck at 39999 and 10000 up ?
I THINK that with Infinity 2, you are first provisioned on the 40/10 service (or whatever they call it) & within a day or two get switched to the 80 20 service.
I'm not with BT for my FTTC service, so I'm not 100% sure about that.
2, Is the SNR quite high, i thought it used to stick around the 6db mark, which would give me better attainable rates ?
No, its good actually. It means you have SOME spare margin to achieve better than 40/10 if/when BT uncap your connection speeds.
It looks like 50/16 will be around the very best you are likely to see though.
3, Been connected for 15mins and done 2 speed tests and look at the error count:
CRC Errors: 100 down 0 up
FEC Errors: 9 down 9 up
HEC Errors: 32 down 0 up
Should i be getting that many errors?
They may just be errors encountered during the initial connection stages.
I have seen connections with zero errors for months at a time.
On the other hand I have seen stable connections with higher error counts.
As your attainable rate is quite a bit below 80/20, it suggests your connection is either far enough away from the cabinet or it experiences some "noise", so if it's not already turned on, Interleaving will show at least some corrected errors.
The error reporting doesn't seem quite right in the Huawei HG612 modem's GUI.
More detalied/accurate data can be obtained either from telnet sessions using xdslcmd info --pbParams and xdslcmd info --stats or automated & graphically plotted using the Windows and/or Linux scripts.
My connection is now stable.
You can see from the attached graphs when it was repaired.
Error counts are still not zero though.
Thanks for your help in advance.
p.s. the BTO modem is hacked.
We could see that from the stats you have provided.
