Hi everyone, I'm new to Kitz and in need of some informed advice.
Apologies for dumping all this info in one post, I hope it makes sense:
My master socket (Line Jack Unit) was recently upgraded to a BT NTE5C + faceplate. My router ('Super Router' HG633) stats improved (SNR + attenuation) and my Max attainable rate increased by 15mbps, to 74mbps. However, the actual line rate remained the same and my interleave depth at this point remained very high (over 2000). This suggested that errors were present on the line.
So, I decided to upgrade to the TP-Link VR200, to match up with my ECI cabinet, which is approx 666 meters from my house.
When it arrived, it connected just fine and the router web interface appeared to show 0 packet errors. Interestingly, the downstream Max Rate had now reduced to: 60.68mbps. I discovered that some errors were present on the line using the excellent TP-Link Stat Grabber (I read a post suggesting to leave the username blank, which solved a login error). The relevant error stats are as follows:
erroredSecs=0
X_TP_US_ErroredSecs=0
severelyErroredSecs=0
X_TP_US_SeverelyErroredSecs=0
FECErrors=54317
ATUCFECErrors=88
HECErrors=0
ATUCHECErrors=0
CRCErrors=1399
ATUCCRCErrors=0
[error]0
Am I right in thinking that as long as there are 0 errored seconds and 0 resets / HRC errors, the FTTC DLM will gradually improve the speed of my connection? Could the FEC / CRC errors have a negative effect on my line?
Other router stats:
interleaveDepth=0
downstreamCurrRate=24999
upstreamMaxRate=16782
downstreamMaxRate=60688
upstreamNoiseMargin=171
downstreamNoiseMargin=139
upstreamAttenuation=175
downstreamAttenuation=164
My FTTC line has been stuck at 24.99 mbps for a couple of weeks now (below the official BT handback rates of 55mb and 32.4mb for my line).
Note - I should mention that my line has synched at 40mb several months ago, on a Talktalk 40mb service and I am considering upgrading to 80mb.
So, my main questions are: Should I request a DLM reset? Would my sync speed of 25mbps be considered a fault? Is this likely to cost a lot of money? Are there any alternatives?
