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

IDNet looks like ADSL Max (G.DMT).

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.

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.

btw i left it with bT and TT connected and IDnet saying it was down, after a short time BT and TT started to drop and connect occasionally.

i am setting all to G.dmt now and will take pictures and upload them
