My ISP is waiting to hear back from BTOR at the moment as it's still with their FTTC diagnostics team. Incidentally the engineer actually re-wired the master socket as there was no explanation at the time as to why the connection kept dropping out. May just be coincidental but the drop in speed was after the rewiring was done, is it possible that a loose wire behind the socket is causing the drop in upload speed? My ISP have confirmed they have not capped my upload speed down to 2 Meg, if this was the case my I.P profile should be set to 2000Kbps. Hopefully this will get resolved soon.

If any wiring faults were causing an 'issue', they would be noticeable on the DS speed first, not the US.

A few posts ago I asked if the DS speeds you were getting were what you expect to get, ie- the most you can achieve from your circuit. If the answer to this is 'Yes', then the only thing wrong with  the poor US speeds (especailly the extreme drop from 8Meg to 1.6Meg that you are getting)  is down to 'Capping'. BTOR can't do anything at all about this, BTw can. I think thats what you mean when you say your ISP is speaking to BTOR ??

Hi razpag,

Yes you are probably right, my ISP just specified that BT would not send out an SFI engineer until the FTTC team had finished their diagnostics, just not sure why its taking so long as it's almost been 3 weeks since the drop in upload speed. Surely it can't take BTw this long to lift the cap!

I couldn't possibly comment.

This is all very strange, at around 6.10pm DLM has kicked in and reduced my downstream I.P profile down to 22898Kbps. My upload is now back up to 7 Meg

Very confused

Did you manage to get the bottom of the REIN? If this is still hanging about then you may experience alot of fluctuation. Seems to be having an impact of both DS and US which is a little unusual however it is FTTC after all and i am sure it is affected in different ways from ADSL.

Unfortunately no, on Friday I was getting a lot of packet loss and my download speeds dropped down to 2 Meg. DLM is still active on the line, which I presume has kicked in because of the REIN. I have another BT engineer coming this week, I think they may reset the line, however I think if the REIN starts again then DLM will start again. I have tried locating the REIN myself but its becoming more difficult as its happening at random times, where as before it occurred on a daily basis.

I take it REIN can affect the line at any point to the exchange or is it more common locally ie your line to the green cabinet?

Is the cable better protected from noise from the cabinet to the exchange?

[roseway]

The downstream signal leaves the exchange at a much higher level than when it reaches you (that's what's meant by attenuation). Because the wanted signal is higher nearer to the exchange, any interference will have correspondingly less effect at that end of the line.

I think as its fibre from the cab to the exchange, the REIN won't be coming from the exchange side, it's more likely to be coming from the cab side, which is 300 metres away. Having said that I am not sure what radius the REIN can affect, I know for sure that a few people in the next street are having similar issues at similar times to myself.

@ Lemsip,

At a practical level, many E side cables are underground whereas D side cables are a mixture of underground and overhead without screening.
It follows that overhead cables are more susceptible to all sorts of RFI.

EDIT re FTTC cables, note that the phone lines on BT cabinets are Shared (Metallic Path Facility) connections, so it's possible, although less likely, that noise is still being injected from E side phone line cables.

Kind regards,
Walter

In my area, according to the last engineer a majority of the cables are fed underground from the exchange, however there are a small number of properties that are supplied by overhead cables.

thanks, so its always certain it will be close to your location.

Its more likely to be from the d-side onwards because fibre being "glass" and high speed it is less likely to be affected by REIN. Worse thing about REIN is it can be anything at all that is electrical right down to someones hair dryer but i doubt anyone is drying there hair from 10am till 10pm unless they go OTT on washing there hair lol. I would maybe go back to looking around the pub area as workers will be in the pub from 10am and usually pubs start there closer procedures at 10pm to give them a chance to get everyone out by 11pm. They could have a faulty router or something along those lines which is causing all this hassle. Try speaking with the owner of the pub and asking him nicely if you can take a walk around with your radio to see if you can pick up any interference. Also do you live out in the sticks? Is your copper line on route to any electrical gates that farmers use to keep there sheep in that is another common one for REIN. Check online and see if you can get a list of common pieces of equipment that cause REIN and that might help you break it down a bit cause to be honest with you waiting around for BT to get someone to send a specialist REIN engineer out is going to take you longer than you expect if the SFI's are not calling it through to the REIN team. If you really want to get somewhere then ask for a manager when calling your SP and apply pressure to them to apply pressure to BTW to get another SFI out to call through to the REIN team to get the ball rolling. What your SP can do is use an escalation process in BTW which raises an escalation case if they are not satisfied with how long it has taken to get this resolved which means they would need to speak to a team coach at BTW to get the case raised.

Thanks Gary,

I will definitely check out the pub, I am not sure if it's a business as the REIN doesn't occur at the weekend. My problem is now, the REIN is not occurring at frequent intervals. When the REIN kicks in, DLM also kicks in on the line which drops my I.P profile by at least half and my pings increase to anything from 30ms-70ms. My ISP is a smallish company so I have been dealing with the manager of the company, he has been onto BTw constantly but they have been slow to feedback.

I have an engineer coming tomorrow, hopefully should be able to reset the I.P profile, however if the REIN kicks in DLM will be right back so I am in a catch 22 situation at the moment. When the REIN kicks in it cripples my connection, sometimes I get 1Meg or less. Can't really wait much longer to wait for this to be fixed as I work from home 2-3 days a week. I may have to get Virgin cable alongside my FTTC connection.
