ADSL Nation NTE-2005 Master face plate

Horrendous line errors

No, fitting a new NTE5 and faceplate wouldn't give you a sync higher than 15323kbps as that is the speed Sky cap most Max customers to (16meg less overheads) as explained to you here.

Those errors are so high there's something really bad going on with your line. If it's not the BT line itself (possible) then I'd take a good look at that Commtel Internet and Phone Guard as something is introducing massive noise. None of my business but I'm curious to know why you need it? Though of course the problem may be with the "3 x 15m extension reels, 1 x two way splitter and 1 x 10m extension reel for connecting 2 x Binatone Speakerphone 510 SMS corded house phones, 1 x BT Freelance XA500 Twin - cordless house phone" you refer to elsewhere

Hi Saturday, thanks for replying back to me. Basically, I'm capped to 15323kbpsm which I'm right in the first place!! I think I get it now, the key is less noise Margin, the higher line speed sync!! I notice the changes something like line Atten starting from 31, then going to 30.5, then back to 31 again, and the noise margain going from 9.6 to 8.8, then back to 9.6 again.

That's ok, I need Commtel Internet & Phone Guard to prevent unauthorized use of the phone when I'm not at home, saving me from paying very huge phone bills, like in the past.

I have draw another Final ADSL Plan, but this time its in full detail.

If I remember correctly, the noise margin is 9.0 and line atten is 31db when connected directly to my pre-NTE5 master socket without commtel phone guard installed as mention in this forum.

So, which Noise Margain is better for me: 9.0 or 8.8? Or please tell me the most suited Noise Margain for me. I have 2 x Sky's Microfilters left.

Sorry, I meant to ask you was, if replaced my old pre-NTE5 1973 LJU2/2A BT Master IDC socket to new moderm BT Standard NTE5 socket, would I get the full benefits e.g. new and improved line atten, less Noise Margin? Or its best to leave it as it is at the moment as it doesn't make any differences at all.

Hi Saturday, I just remembered that I'm using a seperate extension for ADSL connection, as shown in my full detailed Final ADSL Plan. Does it matter? I mean, does it still adding more noise, when using seperate twisted round RJ11 extension for ADSL and three cheap flat extensions for the house phones, Sky digibox & Sky+ digibox.

How can I reduce the noise? I have only 2 Sky supplied microfilters left, or is best to upgrade my old fashion pre-NTE5 LJU2/2A BT Master IDC Socket to modern standard BT socket with engineer's test socket, by getting BT Engineer to come round and replace my BT Master Socket.

Thanks.

Get rid of the "three cheap flat extensions for the house phones, Sky digibox & Sky+ digibox".

I think you'd really benefit from reading the first sticky in my signature to understand noise margin etc. To understand how to improve your wiring, spend some time reading through the cabling and faceplate help forum. In summary, don't use plug in extensions or splitters and fit a new NTE5 with a replacement filtered faceplate and hardwire your extensions into that.

Ouch!! £168.32 for only getting BT Engineer to replace from my old non-NTE5 LJU2/2A PABX BT Master IDC socket to new BT Standard NTE5 Master Socket with Engineer's Test Socket inside, I find out after calling BT to see how much they charge, big bad shocking news!! £116.32 for BT Engineer visit + £52 for new BT Standard NTE5 Master Socket.

Is there any other way replacing my old non-NTE5 socket without paying £168.32, that's a daylight robbery!! Add £31.68 more to £168.32, and that's the total price for my 2 months shopping. I prefer to spend it on my 2 months shopping to last me and my family for 2 months, instead of giving it away to BT Engineer for only between 2 - 20 mins job.

Many people find that their old sockets develop faults and are noisy. When a noisy line is reported a BT engineer is sent out to investigate. Most times BT engineers replace old sockets with new NTE5s. There would be no charge for this. However, BT will sometimes make a charge if an engineer is called out and no fault is found. The above relates to voice call problems only - BT are not interested if you have ADSL problems.

Failing that an alternative would be to buy a NTE5 and filtered faceplate and fit it yourself to the side of the existing old socket then connect the two together and all subsequent wiring being connected to the new socket only.

The cabling and faceplate help forum has all this info covered as I've already advised you. You just need to look for it.

Hi Saturday, after I have another research on the Internet, I just find out about this BT Line Test using 17070, then option 2, which I didn't know all this time until now. I read it and follow it, removing all the extensions, plus the Commtel Phone guard as well, and only plug in my Binatone Speakerphone 510SMS corded phone into my BT master socket to do the test.

I dialled the 17070 number, then option 2, before the phone call was connected, I heard "hum" noise, as if sounded like electronic interference. And then, while I was listening for the Quiet Line Test, I keep hearing small pops continuously like a heart beat.

Is this normal? or do I have a nosily line?

Also, every time, when I make a call using one of the phone cards, and while the call is connected, its goes like this all the time... produce a "hum" sound, then the call went through by says "Please enter your PIN number" - the PIN from the phone card and the same goes all the time when I'm making every phone calls.

And yup! Its definitely LJU2/2A master box as I saw the label inside the master box when I remove my Commtel Phone Guard from my master BT socket.

I took the liberty of taking a picture of my old Brown G.P.O. BT35A Junction Box in the living room, its looks horrible and its old too!! Hanging by wires on each side, even its swings back and forth when I touch it or when the window is open on windy day!! I asked my dad about it and he says that BT Engineer says its fine and its works perfectly when he first installed the phone line back in 1973, but I doubt it very much as it looks horrible and its too old, period!

Oh, by the way, here are my router stats when its connected with only one micro-filter and and router connected via 20m ASDL twisted round extension as follows:

I want to double check first before I report to BT for a fault on my phone line. Thanks, Saturday.
