Hi 22.8 again,

If the external (BT 66 ?) box is accessible it would be neater if a new cable was fitted from there directly into your master socket.
You could fit a standard blanking plate over the then redundant box.

@ Eric, just to avoid possible confusion, I had included the ADSL Nation link to their xDSL v10 faceplate rather than the XTE2005, but
the description doesn't seem to mention whether this unit has their active filter design.

Kind regards,
Walter

Walter, you're quite right. I hadn't realised that ADSL Nation are now selling the modified BT filtered faceplate as well as their own XTE2005. The latter used to have an active filter, but there seems to be no mention of it now, so maybe they've changed the design. In any case, I'm sure that both are excellent products, and your recommendation is a good one.

Hi 22.8,

There would appear to be a good case for having the entire cabling replaced !
However the grime isn't necessarily a sign of a faulty cable.

It appears that the two lines were connected to the internal cable's blue pair and orange pair.
It's difficult to see the condition of the joints from the underground cable, but I would not suggest disturbing them yourself as there's very little slack on the blue pair to remake the connections.

It's possible that even this arrangement was not the first connection of the line as there's no sign of the underground cable sheath.

We will await with interest the BT engineer's visit.

Kind regards,
Walter

Hi everyone, the engineer put the NTE5 where the blanking plate was using the white cable. She removed the blue crimp things, she called them 'beans' and said they were discontinued years ago because they were known to cause faults! She also said the 6 wire white cable wasn't used any more because only 4 are needed and its good as it is. Anyway she stripped back the white cable and connected up the NTE5, then used the other part of the wire which is now attached to the faceplate as an extension to the LJU2/1a. She said if there were any problems with phone or broadband because of having 2 capacitors on the line I could either cut them out of the LJU2/1A, or she gave me 2 LJU2/3As which I could replace it with. Not bad for 30 cash.

For now there is no change in router stats but its only been half an hour so far. I'm also using 20 odd metres of crappy flat, plug in extension wire (4, aluminium, straight) to the lju2/1a until I get a Krone tool, NTE2005 faceplate, Cat5e and a twisted pair RJ11 cable.,

My plan is attach NTE2005, filtered phone to LJU2/3a Using CW1308, and unfiltered ADSL using BT extension kit from Clarity (Cat5e but 3 pair).

Is having 2 capacitors going to be bad? How much speed/ snrm do you think can I gain and how much attenuation can I drop by rewiring as above? Here are my stats:

Just an update, I haven't done any wiring yet, but it seems just removing those bean things and waiting a while has got me a consistently faster sync in the 5700 range.

I've been looking at BT infinity and they use an i-plate like thing like this http://www.run-it-direct.co.uk/btvdslfaceplate.html and the VDSL modem plugs into it, and then you attach a PPPoE capable router to that. Now, I'm not interested until they raise their FUP to something more realistic, but thinking ahead to the future I'm going to use Cat5e (or Cat6 if the diameter isn't much bigger, can anyone confirm 5e is 5mm and 6 is 6mm?) from a filter face plate, shall I plug in or hard wire at the master, and also, what socket should I have on the other end where my D-Link is.

I'm thinking NTE5a (which I have) + NTE2005 + NTE2000 DSL Data extension kit. Does the extension kit have a RJ45 or a RJ11 socket? I'm talking about this one http://www.kitz.co.uk/adsl/images/phone/data_extension1.jpg http://www.kitz.co.uk/adsl/images/phone/data_extension2.jpg

Hi 22.8,

I believe all BT data sockets will be RJ11s.

I don't think you'll get any benefit from Cat 6 which is designed for Gigabit Ethernet.
(We might all like up to 40 Mbps or even 200 Mbps but going any faster just isn't going to happen !)

RE cable diameters you'll see below the specs from one of the better suppliers.

Kind regards,
Walter
