advice needed, dropping out when more than one line connecte


[link to this post]
 
Can anyone help or explain why i have this problem

Currently i have 3 lines installed and am having problems with the lines dropping at the same time. This has been going on for ages but i have just noticed something that might give a clue to the problem.

I have just noticed if i pull the cable that connects one router to the master socket via the filter and then plug it in again it actually causes the adsl to drop on the other two lines, it can take a very long time for all three lines to connect again. It does not matter which line i disconnect/connect the same thing happens.

I really don't understand why this is happening because in theory each line should be separate and should not be affected by what is happening on another line.What happens when the router is trying to connect is there some sort of noise that could be contaminating the other lines that is causing them to drop out?

The trick will be to compare the router statistics, i.e. connection speeds, attenuation and noise margin. When you have just 1 line connected, 2 lines and then all 3 three ADSL modems running on the three different lines.

Crosstalk may be the issue, possibly made worse by other factors.

Is it just the physical plugging in, or does a power off/on on an ADSL modem cause same issue?

Thanks for the reply Andrew

ok here are the partial results

1 line active

BT
speed 3065 up 683 down
upstream noise 6 / output power 0 attenuation 34
downstream noise 9 / output power 12 attenuation 57

------------Connected 2nd line IDnet BT stayed up----------------

BT
speed 3065 up 683 down
upstream noise 5 / output power 0 attenuation 33
downstream noise 9 / output power 12 attenuation 57

IDnet
speed 5600 up 448 down
upstream noise 20 / output power 20 attenuation 31
downstream noise 6 / output power 12 attenuation 59

---------------Connected 3rd line Talk Talk- All lines dropped
After 20 mins Id Net is back up

IDnet
speed 2592 up 448 down
upstream noise 19 / output power 18 attenuation 31
downstream noise 6 / output power 12 attenuation 58

other 2 lines are still down after 45 mins, i will report back with the figures when they are back up.

Power off/on causes the same problem, i will test later if a router reboot causes the problem also

The noise got worse on the BT line even though it stayed in sync, so issue may just be cross talk.

Are the drop wires very very old, and possible not using twisted pairs? This would cause a lot of issues.

For you have NTE5 master sockets for all 3 lines, i.e. to test at the test socket, and eliminate any issues there.

again really sorry for the wrong figures, nearly 3 hours later talk talk has not connected even when the other 2 lines are disconnected. I have eventually just switched it off and put the BT one on which took about 10 mins to connect.

The IDNet line is syncing a lot lower when both are on. This should not happen, I run two lines here. So what I said earlier about checking at master sockets, and I would add avoiding routers being too close to each other, and possibly ditching the supplied flat RJ11 lead for a short twisted pair one might help.

To give you some idea, I've had one of my ADSL lines flapping up and down due to a fault on that pair, but the other continues happily

[re: MrSaffron] [link to this post]
 
Is it possible that the power supply for the TalkTalk hub is extremely noisy and as soon as that is connected to the line the noise levels go way up, cross talk increases and the others fail/fail to connect and because the noise gets so high the other lines will not sync immediately.

As you suggest, the OP needs to get all connection cables to a reasonable quality and then to get the modems/hubs as far apart as possible and try again.

if you unplug the BT and IDNet lines and fire up the Talk Talk line what stats do you get.

Also what ADSL standard is in use - are they all the same ? eg G.dmt / ADSL2 / ADSL2+ or G992.1 / 992.3 / 992,5 etc

Re: advice needed, dropping out when more than one line conn


[re: MHC] [link to this post]
 
Sorry about the delay in getting back to you guys.

I now cant get talk Talk to come on even when the other 2 lines are disconnected, i have had this problem with TT loads of times before but generally what happens is they book an OR appointment but by the time the engineer comes the line is back up so he will test the line and say everything is ok. The last time i discussed it he said the only thing he could think of was to get a rein engineer or do an end to end swap. Trouble is he refused to tell TT that saying it is up to them to ask for it!

ok i have done a few things today and moved the TT router to the next room, the other 2 routers are about 8 feet apart, does that seem ok, they are all plugged into the master test socket, and no phones connected.

When i am trying to get TT to connect IDnet generally connects back up at around half the speed and BT generally is not able to connect.

Are the drop wires very very old, and possible not using twisted pairs?
How do i tell this?

For you have NTE5 master sockets for all 3 lines,
yes all routers are connected to the master socket for each line

Also what ADSL standard is in use - are they all the same ? eg G.dmt / ADSL2 / ADSL2+ or G992.1 / 992.3 / 992,5 etc
looking at the router configs they are all different, should i try changing these? I think all lines should be ADSL2

TT Annex A
IDnet ADSL_G.dmt
BT ADSL2 Mode

Is it possible that the power supply for the TalkTalk hub is extremely noisy
Would the noise only affect the other lines when the cable is connected to the master socket even though the power is on when the cable is disconnected?

OR have looked at the TT line about 5 times and each time they are happy with it.

Possibly yes - but it is just one thought. The RFI can be radiated or conducted. Radiated means that it is transmitted through the air and will be picked up by the other lines - but it is not very efficient. Conducted means that it flows down the wires and that is an effective way to get the noise close to the other lines when it can be picked up.

try setting them all to G.dmt - not auto or multimode. They're all Annex A as that means POTS not ISDN.

A photo of the wiring might help. A non-twisted old drop wire looks like thick bell wire - figure of 8 - with two adjacent parallel cores.

If the TT router won't sync try using one of the others. Don't reconfigure it, just see if it gets a sync better than the TT router and pull the stats from it. That way you eliminate the router or its PSU. On a T-T LLU line the others will probably work anyway, as T-T seem to ignore login details.

[re: MHC] [link to this post]
 
Could the fact that i dont need the TT username and password set on the router to connect to TT be part of the problem. the whole thing is a complete mess as you will see from the following things i did to troubleshoot the problem.

Last night

BT+IDnet were up TT was down (TT had been unable to connect all day)
From my BT router i disconnected the dsl cable from the BT master socket and put it in the TT master socket.
TT connected straight away even though the UN and PW were not set on the router ( they had the BT id's!)

I then took the BT dsl cable out and placed the TT one back in, the TT was able to connect straight away when it had not been able to all day.

stats were

speed 4707 up 864 down
upstream noise 7 / output power 12 attenuation 31
downstream noise 6 / output power 18 attenuation 63

i then put the BT router dsl cable back in to the TT soclet to get the stats from that router but the line would not come back up.

I then put the BT dsl cable back to the BT socket and lest it for the night, BT and ID net were left running. I can see from the Broadband Quality Monitor that both lines stayed up all night.


Then this morning i have plugged the TT dsl cable back in so that is all 3 lines trying to connect

TT and BT are connected and very weirdly the dsl light on the IDnet router is not even flashing, when going in to the router config it just says status down.All light are on on the TT router and in the config it says it is connected but i can not connect to the internet.

stats are

TT
speed 2400 up 672 down
upstream noise 6 / output power 12 attenuation 31
downstream noise 10 / output power 18 attenuation 55

BT
speed 3001 up 730 down
upstream noise 5 / output power 0 attenuation 33
downstream noise 6 / output power 12 attenuation 57

IDnet
dsl light not flashing- status down, getting tone when connecting a phone

No. If they needed it and it was wrong you would get sync to the exchange but no PPP session / IP address.

I'm wondering if the socket / plug contacts are clean and aligned properly as switching routers worked but switching back it wouldn't reconnect.

How are you connecting the RJ11 modem sockets to the BT master sockets ?

One conceptual possibility is that there are split pairs - two lines sharing two pairs rather than each on separate pairs. Photos of the back of the NTE5s would help there perhaps.

can see the slideshow.

So the black cable coming in feeds two sockets - the one it enters (TT) and the blue and white pair where the blue is trapped by the backplate against the box go to the Openreach branded one (BT) ? You can undo the two crosshead screws to see what's happening behind there.

How is the third (IDNet) line connected to the outside world ?

can you confirm the photobucket link is ok please?

since i changed to g.dmt i have all 3 lines running, they did drop when connecting each line but are back up and stable since last night. stats with all 3 lines up are.

TT
speed 3392 up 672 down
upstream noise 6 / output power 12 attenuation 31
downstream noise 3.5 / output power 19 attenuation 63

BT
speed 2400 up 672 down
upstream noise 7 / output power 16 attenuation 31
downstream noise 10 / output power 12 attenuation 59

IDnet
speed 5376 up 448 down
upstream noise 20 / output power 20 attenuation 31
downstream noise 7 / output power 12 attenuation 59


In fact just as i was getting those stats all lines started dropping at around 9:15am, i have had to disconnect TT and IDnet and BT became stable straight away, stats for BT running now are, i see the downstream noise is higher, does that mean anything?

BT
speed 3072 up 704 down
upstream noise 7 / output power 17 attenuation 31
downstream noise 14 / output power 12 attenuation 61

I know BT and IDnet were stable all night because i am using the Broadband Quuality Monitor on them as those 2 have static ip's
This is really doing my head in all i want is a stable broadband line and would be happy with 1 line and maybe another one as a backup but its no good if one going down causes the others to go down alao..

As i said at the start the weird thing is if one line loses sync and tries to reconnect it causes the other lines to drop also.

I tested this by leaving the router on and manual disconnect/connect of the phone wire on one line.

I just tested this again with a router reboot from the router config so i am not touching the power or any wires.

I had BT and IDnet connected, rebooted the BT router and the IDnet line lost connection.

Those pairs do not sound correct. Are they all in one incoming cable or separate?

Or & Wh
Gn & Bk
R & Gy
Bl & Bn

are typical pairing in CW1417 with just the first two pairs used in CW1411

If possible can you actually draw out a diagram of the telephone network cabling - starting with the external dropwire(s) and where they are terminated, then the colours and pairs of wires where you can see them - show which wires are in which cable.

It really does sound as though, somewhere there is massive crosstalk, a split pair, short circuit, or a load split across circuits. It might be inside your network, in the BT network in your house, or external.


You may have to bit the bullet and get BT in to strip everything out and reconnect from dropwire to sockets. If that fails it would start to suggest the problem is external to your property.

Can you get a real close up of the cable - any writing on the side? Would be nice to see the real colours as it leave the outer sheath.

Can you try flexing one of the white conductors ... does it bend and stay there or does it spring back?

Yes i will do that later when i have more time if it will help.

Just to let you know none of my internal wiring is connected while i am doing these tests so that can be ruled out.

The only things connected are the 3 routers each into a filter and into the master test socket.

Re: advice needed, dropping out when more than one line conn


[re: MHC] [link to this post]
 
ok i have added 4 new pictures, all boxes are fed from the one black cable that has no numbers written on it unfortunatly. The BT box has a wire joined to it but the other 2 boxes the wires are straight from the black cable with no joins.

So the colours for each box from the black cable are

TT Blue/White

IDnet Green/White

BT Orange/White

I will now draw a digram of all wires coming from the black cable

How many wires are actually coming from the black cable? And what are the colours of them all? Do any have a second colour/stripe?

I can see: Brown, Grey, Blue, Green, Orange and Whites.

If there Bl x2, Or, Gn, Bn & Gy then it is likely to be CW1600 phone cable and care needed to ensure the right whites are used with te other cores.

Where does the second blue come from? Have seen your later post.

Have a close look at the white wires - are there any small coloured marks?

Do the pairs look as though they are twisted together in the cable?

If so, that is likely to rule out a split pair and the cross talk it would cause.

another 2 photos of wires coming out of the black cable, it really does not look like they are twisted and the wires are plain white with no other writing or colours on the wire.

they are twisted with a fairly low frequency not like a pigtail

Certainly from what i can see what is coming out of the black cable there are no twists.

The only way to look closer would be to cut a bit of the black off, i wouldnt want to damage anything tho.

Thats a 5 pair PET UG cable, so the colours look look right for the pairs.

No doubt that a split pair on this cable would cause the issues reported, trouble is, with them being pulled apart right down to the cable butt, you can see nowt. You'd have to get to the other end of it and work back.

Zarjaz has confirmed the cable type but it is going to be difficult to prove which wires form a twisted pair.


I really think you have gone as far as you can, some of us might go a little further but do have relevant experience. You need to document EVERYTHING and get hold of IDNET, TT and BT and tell them all that there is a problem. Get IDNET and TT to tell BT that you need a technician visit but you only want one visit to look at all three and get the BT fault reference for it.

Then, get onto BT and tell them the same, insisting you need a visit but it has to coincide with the requests from the other two - when they initially refuse insist on escalation of the problem.

Re: advice needed, dropping out when more than one line conn


[re: MHC] [link to this post]
 
To give you some background the TT line was here when i moved in around 7 years, that line had problems when getting an incoming call it it took OR 10+ visits 2 lift and shifts and over a year before it was fixed, i had the IDnet line installed as a backup during that time and at one point OR have swiapped those lines over because now the IDnet number corresponds with the TT box.

A few weeks ago i ordered a line with BT business with the view of getting a fresh line and then getting one of the other lines disconnected if i could pinpoint which one was causing the problems. Since the BT line was installed i have realised that when one line is unplugged/plugged it causes the other lines to drop out also, i did not realise that before and it now explains why the old 2 lines were dropping out at the same time.

From the information i have given are you 100% certain the problem is with OR and nothing on my side, i cant see how it can be anything my end as the 3 routers are plugged into the test socket and i have no phones connected.

I guess i have a few options

1/ As you suggest get in contact with all 3 ISP's and somehow get them to work together.

2/ Call BT business and get them to send OR as they have to come out within 24 hours but are they allowed to look at the other lines? with the other 2 lines disconnected it should solve the problem of any crosstalk?

3/ Disconnect TT and IDnet as they are out of contract and hope the BT line is stable

a split pair is going to perform badly in any case, it won't get the crosstalk but will be much slower than it should be.

From memory the IDnet line was quite a bit faster sync speed than the others when on its own ? if so it might be OK and the other two have their pairs mixed up.

Go down option 2 ... Call BT support and tell them about the problem - the Scots tend to understand English but do not mention the intention to get rid of the TT and IDNet lines. You need to get the support tech to escalate it to his Coach - not quite second line but experienced and has move flexibility. Hopefully they will understand about split pairs and cross talk plus the need for OR to attend. It will then be down to your powers of persuasion to get OR to look at all three although checking for split pairs should be routine in a case like this.

Or, do as above but leave fault open saying you will call when you know your availability. Get IDNet or TT to book a BT Tech visit and then call BT Tech support again and arrange the visit for the same day - at least then you have a chance of making the Tech look at both

i have went for option 2 and got an engineer coming on thursday, i must say BT are much better over the phone as TT it has been so frustrating dealing with TT.

Cheeky [censored] tho BT will charge you £220 if the fault is from inside the house where TT were only £50, that is a massive difference, what do OR actually charge them?

what is the chance of this being a fault my end, it has got to be 0% right if it is happening over multiple lines when i have no internal wiring or phones connected and all routers are into the test socket?

It should be easier this time to show the engineer what the problem is as i can just disconnect/connect one of the other lines to get the BT connection to drop. What else do i need to be doing, ask him to check for split pairs on all lines, anything else?

None.

Split pairs are, sadly, very hard to detect in the real world. The only thing to look for on the PQ (pair quality) test would be low AC balance, the pairs ability to 'deflect' external signals.
Would be interesting to see the other end of the 5 pair cable feeding in, since those at your end (as pictured) have been split right back to the cable butt.
By their nature, these smaller cables tend to have less sheathing removed when terminating, you then pull the colours, and it's associated A leg comes away with it, on short lengths however, there isn't enough twist in the exposed pairs for this to happen successfully.
Hence the white A leg of pair 1 (blue/white pair) ends up being wound around the orange of pair 2, whilst the white is around the blue of the first pair.
This is basically not too much of an issue over short lengths, at least for voice. However it can play merry hell if both the pairs are carrying ADSL.
The difficulty the SFI will have, is that they can only test the sync on one line at any one time whilst in the field. having only tester.
Just a suggestion, but to rule out that it isn't the 5 pair causing the issue, get the SFI to push the TT line up on one of the two spares, the browns or the slates, toning from the external joint to ensure it IS a straight pair. Then reconnect all three lines to see if this has sorted it.

Can't remember without looking back through it all, did you rule out that it wasn't the power supply for one of the routers causing the issue ?

Not in the vicinity of Reading by any chance ?

Zarjaz has said most, but three points to remember.

Don't tell the BT Tech his job - make some suggestions (from Z's post) in conversation when he arrives and show him a faulty set-up.
Don't hover over his shoulder - wander away and just ask occasionally if he has found anything.
As he may be there some time make sure you offer tea, coffee, biscuits &c.

Yes i guess the fact OR have looked at my lines umteen times will explain it, i guess one of the engineers pulled them right back to the butt at one stage.

This is basically not too much of an issue over short lengths, at least for voice. However it can play merry hell if both the pairs are carrying ADSL.


I cant remember the exact distance but the last engineer said it was a very long way to the cabinet and when that cabinet got fibre the speeds wouldn't be relatively poor due to the distance.

The difficulty the SFI will have, is that they can only test the sync on one line at any one time whilst in the field. having only tester.

I will try and see what he says smile

I dont think we did unless you can see it from the line stats?
Later i will test agaiin with all the combinations of 2 lines

BT TT
BT IDnet
TT IDnet

That should rule out any one particular router or power supply.

Not in the vicinity of Reading by any chance ?

I see so the black cable does not go all the way to the cabinet, how far is it likely to go?

I just remembered i lost my phone service a few years ago when the builders went through the cable, if this was not fixed properly or the wires not reconnected properly might that be causing my problems?

Do my experiments today rule out the power supply being a problem?

Possible, less frequency bands involved so could be faster to find a solution and may be less prone to interference.

To give you an update the OR engineer did allot of work this morning he was here over 2 hours and rewired all 3 lines he said all 3 lines had split pairs.

The lines are better but on checking after he had left the IDnet line still drops when the BT line is disconnected/connected. I did phone the engineer but he was out of the area and told me he was not allowed to come back because his van was tracked.

I will do my 3 line experiment later and post the picture to see if you still think there is a split pair.....

It shows the results of my 3 line test and a picture of the broadband monitor on IDnet and BT, i can not monitor the TT line because it has a dynamic ip.

I will do another diagram of which wires are where tomorrow

Note the download speeds are all quite similar but why is there such a difference in the uploads?

Different products. IDnet is on a 448 upload "Home" product, perhaps on 20CN rather than 21CN.

New pictures and diagram uploaded to the new slideshow

Only difference i see is the crimped connections to the BT box, the coloured connections to the BT and ID boxes are the same but i guess the white ones are different?

Also when the engineer first tested he put his phone tool into the BT connection and could here the noise of the router even though there was no router on that line, from then he knew there was a problem.

Please see my picture of the 2 line test i have done today

http://s1274.photobucket.com/user/kevcasson/slidesho...

Do you agree there is still crosstalk but only between the BT and ID lines now?

Looking when BT and ID are the only routers powered up

unplug/plug BT the ID line drops quickly as the DSL light is flashing on the BT router

unplug/plug ID the BT line takes longer to drop and only drops when the DSL light is solid and just as the internet light starts flashing on the ID router.

From that can you tell me which line is wired wrong or could it still be both lines wired up wrong?
