Re: SNR Margin on VDSL compared to SNR MArgin on ADSL

Hi SeanD

 

Engineer has been. A really helpful fellow who saw errors on the line. Voice side was checking out OK. Checkeed the wiring of the master socket as well.

 

He went to the cabinet and moved the port I was in, is this a port in the Fibre cabinet that he would be referring to.

 

Broadband is back up and he has called to say he see's no errors anymore.
He says that there will be a couple of reset's to happen - would that be the IP Profile reset and a DLM reset he is referring to.

 

I am monitoring the SNR margins meantime using Router Stats Lite for the HH5, it was 6.2 when it came back but I can already see it dropping - currently 5.6

 

Your thoughts would be much appreciated

 

Thanks

Re: SNR Margin on VDSL compared to SNR MArgin on ADSL

You are correct in what he was referring to.

 

Monitor your SNR over the next few days and keep us updated.

Re: SNR Margin on VDSL compared to SNR MArgin on ADSL

Hi All.

 

Thats about 48 hours since the engineers visit. ADSL hasnt dropped as of yet. SNR seems to be sitting at 5.5 pretty well most of the time. I have copied in some extracts of the logs.

From the logs, the Down SNR seems to be sitting at around 5.5 most of the time - is this OK. Also the last 2 columns are the max Upload and Max Download. The Max Download is dropping from when it established a connection - is this something to be concerned with

 

Thanks in advance for any info and advice that you have

Re: SNR Margin on VDSL compared to SNR MArgin on ADSL

Well I spoke to soon, VDSL dropped this morning at about 5.30am and re-connected at a higher speed but the SNR is lower. Unfortunately my Laptop monitoring the Link died as well so I dont know what the stats at the time of diconnect are. I have moved to a more stable PC now

Re: SNR Margin on VDSL compared to SNR MArgin on ADSL

Your down SNR is still below target and is the most likely cause of your problem. From your logs things were looking good until it dropped below 6.0

 

Perhaps request a BB Boost engineer out to sort it?

Re: SNR Margin on VDSL compared to SNR MArgin on ADSL

Thanks for the info

Would I have to go thru the whole support story again

What exactly does a Broadband Boost entail - is it another engineer visit

Sorry, for asking but I haven't heard of a BB boost before so I apologise for my inexperience with the term

Re: SNR Margin on VDSL compared to SNR MArgin on ADSL

Yes it would entail an engineer visit. There's a problem somewhere that needs to be tracked down IMHO.

 

I'll ask a mod to drop in again and deal with him/her.

Re: SNR Margin on VDSL compared to SNR MArgin on ADSL

Thanks again pippincp - if I was in your town I would buy you a pint or a coffee, whatever your choice was for your help 🙂

 

I have included my logs from  19:15 tomight when it was pretty erratic although didnt drop out. It does seem to be not behaving
