I installed a BT iPlate yesterday to try to improve the very slow broadband (we are at almost the maximum distance from the exchange). Now whenever the house phone rings the TalkTalk broadband connection drops outs.
The setup is we have two phone lines into a master socket (BT and TalkTalk). The front socket on the master socket isn't used, the two lines come out the side/back and feed around the house in the walls. All phone sockets in use in the house have ADSL filters installed. On each line we have a different router, again one on BT (for work, Draytek Vigor router) and one on TalkTalk (home use, using the TalkTalk router).
I'd recently replaced the cheap adsl filters with ADSL nation filters and improved connection from 300k to 1mb (daytime) and about 400-500k (evenings).
This was all working until the iPlate was installed, any ideas ? The iplate isn't directly used but on initial install the SNR improved and connection speed.

Can you take a photo?
When you look at BT's iPlate it looks as if it's only designed for normal Master Sockets with 1 line - so I'm guessing you've got some type of dual line NTE which probably isn't compatible.

I'll get one.... it looks like a normal NTE5 wall box on the outside. I took the lower section off to connect the iplate, 4 wires into the front part and very little else to see. I don't really understand how the two separate lines work from the master socket but BT did install the extra line. They are just routed discreetly around the house to the extension sockets. One line goes to the 'office' and the other to the hallway for a DECT phone base unit.

If you're at the limits of reach I would recommend a filtered faceplate instead of the iplate.

As badger says, a look at the install as-is would be a help.

if everything else was left unchanged then perhaps the connection from the iPlate into the master or the faceplate into the iPlate is a bit dodgy ? see if jiggling it around with the screws undone affects things.

Could be worth unplugging the router first in case 'jiggling' causes the DLM to raise TSNRM...

Photos from camera phone so not high res but reasonably clear. Not sure it adds much ?

I did reboot it after the iplate was fitted just incase. It was later in the evening the drop out problems started.

I can't see what looks like a normal NTE5 can be correctly 'servicing' two phone lines?!
There only appears to be one TEST socket so I can't see how this can be for two 'correctly wired' lines...

Agreed, its odd to say the least but its what a BT engineer did when the 2nd line was installed. Well iPlate doesn't work with it. As suggested a proper filtered box would be better anyway and get it done properly.

Is there another NTE5 for the second line hidden behind some furniture somewhere?
|
|
|
There should be a second NTE5 master socket for the second line, failing that a dual line master socket should have been used but it isn't like a NTE5 at all > link

I can't see what looks like a normal NTE5 can be correctly 'servicing' two phone lines? Most phone lines to a residential property come in TWO pairs within one cable to permit TWO phone lines. Most properties only USE ONE pair for a singe phone line. Some, like myself, use BOTH pairs for TWO lines.
I would suggest the OP has the following: - Both pairs comes to the master socket in question.
- One pair feeds this master socket as Line 1.
- The 2nd pair passes thro' the back of this master socket to elsewhere in the house.
- Also an extension to Line 1 passes out of this master socket (from its front faceplate if wired correctly) to further slave sockets of Line 1.
- The 2nd pair reaches another master socket, for line 2.
- An extension to Line 2 passes out of this master socket to further slave sockets of Line 2.
Because the are 2 phone lines (& #s) there must be a 2nd master socket, even if nowt is plugged into it.

The 2nd line goes upstairs to the 'office' (bedroom) to a wall plate. This is has a separate phone and adsl router on it. This is for work, not too worried about the speed so hadn't tried to put a iplate on this connection.
|

Ah! See earlier posts and replies! 
This is what I couldn't figure out. So the iPlate/NTE5 is actually just serving the 1 line?
|

i think what the engineer has done here is used the greens in the structured cable contained within the walls of the property to feed the second line upstairs.
this is a very common practice utilising the available spare to prevent the need for running cables around the facings to get to the desired location, its likely he has used some sort of twin socket half main/half extension where line 2 is terminated.
the outcome being that the new line is where its required and the existing line continues to work hassle free and with no additional wiring.

Yes, sorry if that wasn't clear. Yeah just one line so in theory it should work and the adsl line shouldn't drop when the phone is used, I thought.

Correct.
I would still recommend binning the iPlate and going for a filtered faceplate instead - at the fringes you need everything to be as good as it possibly can be. I guess it's rather like HAM radio in that respect...
The ADSL dropping when the phone is used is often indicative of a line fault (often a single failing joint on the line). Does it do this when you connect a filter to the test socket and use that only? Do all your extensions on that line go dead when you use the test socket?

I'll test it soon. If we went the route of replacing the NTE5 faceplate, is that something your supposed to get BT to do ? Even though we are with talktalk for the plate in question, the 2nd line to the bedroom is BT.
|

The 1st line faceplate has nothing to do with the 2nd line and, therefore, nothing to do with BT.
In fact, the faceplate has nothing to do with TT either, as it is your side and responsibility of the connection, and you may do to it what you wish.

I did some testing today. Just plugging the router into the test socket behind the faceplate (no iplate) sync several times at 1.8 mpbs !!!! The best it even gets is about 0.8, usually around 0.6 to 0.4. That's quite a massive improvement, so the degradation is caused by the internal wiring it would seem. I then plugged in the iplate and tried the router plugged direct into that but today I couldn't get it to connect at all.
I also tried just the router as normal on a extension socket, a filter and all other components disconnected. The speed as back to the usual sub 0.8mpbs, it has to be a cabling fault then to loose so much speed ?

Without the iPlate being used take a look at
http://www.thinkbroadband.com/faq/sections/radsl.htm... removing the ring wire does most of what the iPlate does, but without introducing an extra set of contacts.
If the wiring is odd, i.e. pin 3 at the master, is connected to 2 or 5 at the extension, then the iPlate I believe will mess up your ADSL.
Pin 2 at master should go to pin 2 at extension.
3 to 3 (or disconnected at both ends to avoid ring wire issues)
Pin 2 to pin 5
Also wires on 2 and 5 should be from the same twisted pair.

After a bit of a delay I've pulled the ring wire and the SNR etc improved a very tiny bit. Connection speed is still around 0.6 mbits but using the master socket behind the front plate gets 2mb.
Not sure what to do now due to the complicated dual line setup. I guess get a professional in to find the problem ?
