Maximise Premises DSL Signal to Router Jack Socket – then Call Support to RESET!

To squeeze as much data as possible from your ADSL/VDSL (Asymmetric/Very-high-bit-rate Digital Subscriber Line) connection, you can examine and test your current premises connection speed, wiring and sockets for optimum signal transfer. I'll explain what I did to improve conditions from a DownStream Attainable connection speed of 3.6Mbps (DS Attainable Rate):

sh-adsl.png

To the DS Attainable Rate of 9.1Mbps at the router extension I currently have (higher later again!) and explain it all as I go:

9-1mbps

Some, but not all of the above info is in the web console view under WAN Online Status - most home router makes should show a similar web page, or have a telnet option as above:

adslstatus.png

The modulation setting for my Vigor router ADSL connection is multimode by default:

mode.png

For my Vigor router, I found a telnet connection from a linux terminal gave me more condensed info once you learn the most important tech terms, numbers and what they mean for your signal. From your linux or Win box:

telnet 192.168.1.1
Trying 192.168.1.1...
Connected to 192.168.1.1.
Escape character is '^]'.

First, the 3 important terms you need to know and why are explained in the video:

Sync Rate: The higher the better; optimum line timing via handshake; the fastest clock speed the devices agree to sync to.

Attenuation: The lower the better; lower means your signal level has been reduced less for a given distance from the exchange, so a higher signal to noise ratio available at the customer end, so a cleaner signal, so higher throughput and less errors.

SNR Margin: Depends on line conditions; A balance between speed and stability - the higher the margin, the more stable, but slower the link and vice versa. The kit will optimise this condition over time - up to ten days.

SNR: The higher the better, means a larger signal; the ratio between the desired signal voltage or power level, divided by the undesired noise voltage or power level.

Optimisation Options

The basic idea for premises suffering poor Throughput speed is to maximise whatever DSL signal level you get at the end of the BT provided drop cable which is terminated inside the NTE5 box, behind the second cover plate, and MUST NOT be touched directly by the customer, as it is BT property, and you risk a fine if doing so, to pass on the the extension that the router will connect to.

Signal optimisation can include a combination of things from;

removing unused extension wires from the main box extension connection points (unwanted aerials and mains hum induction noise)

removing the orange (pin 3) "mostly" redundant bell wire from all connections (unwanted aerial, circuit noise). Most modern electronic phones ring without this wire. IF a particular phone/bell needs a ring wire, add the orange only on that extension or try using a filter first.   

tidying bird's nest wiring (excess slack spare extension pairs twisted together etc) at the main box (unwanted radio/mains hum induction noise)

dsc_0003.jpg

keeping the twists in the wire pairs as far as you can up to the punch down points (minimises radio noise)

running cat5 or 6 cable to the router extension jack (minimises HF noise, optimises DSL frequency distance)

join a cat5/6 RJ11 patch lead directly to a router specific extension cable pair, if full CAT5/6 rewiring is not possible, and plug directly to ADSL/VDSL main faceplate or filter, then also change to an RJ11 data jack at that router only extension if no phone is also required there (no extra filter required at the extension then just for plug type)

dsc_0002.jpg

buying a good quality NTE5 VDSL filtering faceplate to split voice and DSL signals at the BT line jack, before DSL frequencies are reduced over the extension wires, and forward just the DSL via the A/B pins to the router extension only, (or plugging the above RJ11 patch lead directly into the VDSL data socket without a filter) leaving the voice signals behind for the phone extensions only (see vid later)

vdsljack.png

vdsl.jpg

buying a good quality filter to split the DSL line signal to the router extension instead of the VDSL plate above for use with a standard BT NTE5 faceplate,

http://www.adslnation.com/products/xf-1e.php

xfe1e.png

You seem to get what you pay for with filters - and you want the best quality to optimise your signal - but in my tests below, I found the VDSL faceplate for £8 gave a better result - by 2Mbps sync rate - than the £10 ADSLNation filter with a standard NTE5 faceplate.

Most situations will be a combination of the above options.

First, I tried the ADSLNation filter as it arrived first, to send a filtered signal further down my longest 20+ meter router extension distance, and cut and connected the RJ11 patch cable direct to the extension wires - best to solder them, but I twisted the solid cores to the stranded cable and it works fine - be sure to insulate the wires from the patch cable foil sheath.

The NTE5 extension wiring was a tangled mess of spare wires from 4 lines, so they were cut back and tidied, and an unused extension wire removed completely. So, now I have optimised the hardware for my given premises.

So what to do first? Get the BT line max capability reference...

You can remove the BT line jack customer faceplate (to add your extensions to the insulation displacement, punchdown type connectors as in the vid below.)

You can test the raw BT line signal condition here, as it is at it's best when the faceplate is removed, by plugging your router into the socket behind the customer faceplate:

dsc_0003.jpg

All your current extensions/wiring are now removed from this line when the customer faceplate is unplugged. The numbers you get here will be the reference for what the BT line is capable of delivering, and a comparison for after you optimise your extensions. Wow! 11.3Mbps Attainable sync at this socket!

11mbps.png

Next, if you test again at your usual router extension with the customer faceplate plugged back in, so it's including all of your extensions and phones in parallel with the main line, there will be a drop in signal strength, line speeds and an increase in noise as the signal gets shared over the premises wiring and all its associated phones - 3.7Mbps Attainable - terrible compared to the BT jack eh?!

beforeug.png

The extra extensions may add considerable noise when not filtered adequately, such as mains hum, radio interference (the extensions act as aerials), and lower overall line impedance due to equipment in parallel, and so the signal to noise ratio. This is what we want to improve.

ext.png

The raw BT line signal level quality and strength is determined by many factors that affect your individual line - distance and power settings from exchange, wire resistance (corrosion, joint crimps, poor terminations etc.), noise on the line, weather conditions (damp) etc.

The signal quality can then affected by the same things inside the premises extension as for the main line outside.

This line carries modulated AC voice and data signals over a 50V DC exchange battery voltage.

A POTS line requires ADSL filters inserted into each extension that has a phone inserted so the higher frequency ADSL signals cannot be heard on the phone, and are not lost from the router connection. This ADSL signal sounds like a white noise hiss if you plug in a phone without a filter.

These removable NTE5 faceplates are designed to isolate BT property from customers extensions for BT testing and legal separation (demarcation point).

I investigated this topic after checking my Throughput (useable data) download rate and finding a pathetic 2.8Mbps throughput speed on my bedroom (furthest from NTE5 line termination) router jack - which I have measured at 4.5 Mbps Throughput in the past via sites like

http://www.broadbandspeedchecker.co.uk/

http://www.speedtest.net/

- but now using my Plusnet ISP suggested test site as a constant reference - which is important as different sites can give very different results (and you may need to run the test a few times for avg consistency) - here:

http://speedtest.btwholesale.com/

broomtputspeed.png

Why the drop from the prior 4.5Mbps to 2.8Mbps? Because I have been turning off my router at night to not have the lights bother me, and recently changing a lot between a Vigor and Cisco router to recap Cisco for some IT work I have to do.

This causes the exchange kit to drop the line speed for the sake of stability, as it assumes line fault conditions. It can take 10 days for a line to stabilise at it's maximum Throughput download speed - assuming you haven't been rate/service capped and don't know it - PLUSNET!!!??? 

Why do I state that? You can see above that the improvements in sync speed after I have modified my extensions have not changed the DS Actual Rate from 4.5Mbps when I can get 12Mbps ADSL2+ sync rates at the NTE5 drop cable termination!

What services and speeds can you expect for your premises? You can check for your telephone number area here:

http://www.kitz.co.uk/adsl/btwchecker.php

bbareaavail.png

The clue to not being automatically speed upgraded by the BT system when line/system improvements occur seems to be in that small print in that services table above:

"For all ADSL and WBC Fibre to the Cabinet (VDSL or G.fast) services, the stable line rate will be determined during the first 10 days of service usage.

This line is on a Market A Exchange.

For VDSL or G.fast Ranges A and B, the term "Clean" relates to a line which is free from any wiring issues (e.g. Bridge Taps) and/or Copper line conditions, and the term "Impacted" relates to a line which may have wiring issues (e.g. Bridge Taps) and/or Copper line conditions.

Throughput/download speeds will be less than line rates and can be affected by a number of factors within and external to BT's network, Communication Providers' networks and within customer premises."

To me, this means that unless you get your line reset by Support when you/BT improve your connections, you will still get the rate you were "stabilised" at over 10 days, when you first contracted, so you MUST contact support for a reset or your Actual Rate (4525Mbps in my case) won't improve!

You can see from the router output I have an ADSL2+ connection protocol, but at best seem to be getting only the ADSL Low sync rate of 4.5Mbps in the services table - why has Plusnet not upgraded me to the available ADSL2+ line speed I am connected to when it was first installed in the local street FTTP (fibre to the premises) cab 2 years ago?

I am only 2km from the exchange. My router is aware of the protocol and receiving it, the clock sync rate is higher, but my throughput is crap because my DS Attainable rate is maxed out at 4.5Mbps!! I'll wait til I have done all the mods I need then ask the Plusnet help desk to reset the line conditions so the exchange kit settings can start afresh, and grill them on the line speed.

After my initial improvements of tidying a bird's nest, removing an unused extension, connecting an RJ11 patch cable direct to the router extension, adding the ADSLNation filter to the NTE5, and using a filter to connect from the router telephone socket to the router (I could change that to a dedicated RJ11 data faceplate maybe, and dump the filter), I got 8.3Mbps Attainable, but still DS Actual Rate limited - bugger!:

linestats2016-10-27-20542.png3

For practical connection options examples and workings see the vids:

VDSL Faceplate Arrives

Now I can see what differences this makes, without the ADSLNation filter and the NTE5 main phone only socket.

First reboot the router and take a current system state reading at the router extension jack:

prevdsl.png

After changing to the VDSL faceplate WITHOUT ADSLNation filter:

postvdsl.png

Wow again...an increase of 2.7Mbps to 11Mbps DS Attainable - at the extension! - with this plate, instead of the ADSLNation filter. That's as good as the NTE5 BT line test was. Great result.

So, seems the VDSL faceplate filters are built to a higher tolerance, as you would expect for the signals they are designed to optimise, so I'll stick with that and use the XF1 ADSLNation filter on the router line jack in place of the current one to help remove any noise induced on the 20m extension run.

Also, it seems the XF1 filter description as an "active" device using transistors must be incorrect, according to the webpage I read, as they may have been mistaken for "triacs" not transistors by the reviewer...it was a link off kitz somewhere I thought...anyway - I can't see technically how you could have an active "amplifier" allowed on a BT circuit anyway, or where the same blue pair of BT wires are used as transmit and receive - a transistor amp doesn't work like that as it's unidirectional for gain.

VDSL

I recently did some Cisco router, work related reading via kitz.com on the current Century21 backend system that BT has been rolling out over the last few years, and what newer line termination options are available since I worked for BT back in the late 80's/early 90's - all you need to know about DSL and much more:

http://www.kitz.co.uk/

"The PSTN (telephone) services will be provided over the same IP network as broadband. This will involve replacing telephone switching equipment and the adsl broadband DSLAMs (Digital Subscriber Line Access Multiplexer) with MSANs (Multi-Service Access Nodes) which will terminate telephone and broadband connections." 

The upshot of this core upgrade is massive speed increases for VDSL links compared to current ADSL2+ phone lines, where available. I recently upgraded some Cisco routers on 2 business sites and cut them over from ADSL to VDSL and the initial connection DownStream speeds went from 8Mbps to 58Mbps in one case:

vigorspeed.jpg

ciscospeed.jpg

and from 3Mbps to 57Mbps:

c800speedtest.png

cisco897vaspeed.png

Amazing leap in practical use tech eh?

For the real nerds...as stated above, you also get what you pay for with routers, and Ciscos are expensive for good reason - their ability to negotiate power levels for one, so more likely to function on poor lines where cheaper tech would fail. Here is my 877W connecting after the optimisations above - immediately getting a higher throughput closer to the capped sync rate than the Vigor:

ciscospeedpostvdsl.png

They are choc full of clever line conditioning algorithms for multiple tones, that a glimpse of the output of the command:

 show dsl interface

will convince you of...and pages of data is output - but an interesting section shows a higher attainable rate than the Vigor showed at the BT line - of 13.3Mbps

RParam: LATN (Channel Attenuation) = 35.4 dB
RParam: SATN (Signal Attenuation) = 35.4 dB
RParam: SNRM = 23 dB
RParam: ATTNDR (Attainable Data Rate) = 13309000 bits/s

The 1st page of:

 show dsl interface atM 0

gives a similar short summary as the vigor above - line speed near bottom - 4525 kbps - that capped rate:

ciscossyncpeed.png

To show why you need to re-run speed tests - I just got 5.68Mbps as a throughput result, which can't be possible, with a line rate of only 4.525Mbps sync:

5-7mdl

Testing again gave the usual 3.8Mbps as before, so more like reality.

And finally, back to reality...but I'm happy with it...

I found the stats I need to contact Plusnet Support many pages into the Cisco command results - but ONLY if enable logging is turned on:

sh dsl interface

Calculating attainable bitrate
Calculating relative capacity occupation
Downstream Actual Bitrate fast = 4525 kbit/s
Downstream Actual Bitrate interleaved = 0 kbit/s
Downstream Noise Margin = 23.0 dB
Downstream Relative Capacity Occupation = 45
Downstream Attainable Data rate = 13309 kbit/s

To ensure you have proof of contact - copy and have emailed the Support transcript should line conditions not improve after your reset. Here's is my online chat - note I asked specific questions about expected actual rates, so I force a rate value reply from Support so I have figures to reply to them with if I don't see an improvement.

I've tested your line and can see that you're staying connected to the internet. However there are some automatic settings on your line which are limiting the speed you're able to achieve.

I've arranged for the line to be reset to try and fix this. The reset normally takes 4 hours to complete. After 4 hours your router will need to be powered off for 10 seconds and then turned back on. When it reconnects we'd expect the speed to be normal again, but it can take 24 hours before everything fully updates.

As part of resetting your line, this also starts a fresh training period on the line. This lasts for 10 days and you may see your speeds vary a little as the line tries to work out the best balance between speed and reliability for you. You may even see that your broadband connection drops a little over this period, but this is perfectly normal.

Whilst in this training period, please make sure that your router stays plugged in and powered up continuously. If you don't then you will receive a slower speed than your line may have been able to support.
steve at 12:29, Oct 29:
ok thanks

Is there anything else I can help you with today?

steve at 12:39 I just got a confirmation txt this time repeating the above info, so in 4 hrs I'll reboot and check again.

4.5 hrs and a reboot later, still no increase...so pathetic in this day and age - how is the Line Management NOT capable of doing this on the fly at all times??? How many people are getting slow rates from year's old 10 day training periods that are obsolete due to newer ADSL2+ connections because they haven't reset the line???

What a complete BT tech oversite cock-up!! Do I expect any different from "couldn't give a shit corporations"?...No, of course not.

Calculating relative capacity occupation

My lines rates from my router are still:

Calculating relative capacity occupation
Downstream Actual Bitrate fast = 4525 kbit/s
Downstream Actual Bitrate interleaved = 0 kbit/s
Downstream Noise Margin = 23.5 dB
Downstream Relative Capacity Occupation = 45
Downstream Attainable Data rate = 13597 kbit/s

my throughput via http://speedtest.btwholesale.com/ is attached at 3.68M

I should be getting near 12M on this ADSL2+ line 1/2 mile from the street cab, with sync speeds of 14M at my extension!

Will you reset and fix this please?? This whole sorry performance is logged on my IT website, so Plusnet needs to redeem itself. It's bad enough I should have had faster speeds years ago when ADSL2+ became available locally, instead of being rate banded until I found out.

Getting there finally - a step closer! Still only got 3.8Mbps Throughput until BT remove the "banding"...? This is at the router extension sync speed DS Channel 0 value, remember - NOT the raw BT line!
Tue 1/11/16 1am
Found the figures the easy way using the Cisco web support page on the router;
http://192.168.1.1/exec/show/tech-support/cr
searching "Attainable" to see my Actual AND Attainable are about equal now - BUT - I still only get 3.8Mbps throughput...
Calculating attainable bitrate
Calculating relative capacity occupation
Downstream Actual Bitrate fast = 12105 kbit/s
Downstream Actual Bitrate interleaved = 0 kbit/s
Downstream Noise Margin = 6.0 dB
Downstream Relative Capacity Occupation = 100
Downstream Attainable Data rate = 12112 kbit/s

Just sent these results (similar to last night) to Plusnet after the 24hr period they requested for router reset:

Hi Support
28 hrs later, as requested, I have reset and checked my line again, 10.30am 1/11/16 and am now getting very high Actual and Attainable rates over 12Mbps and 100% used capacity - excellent figures it seems:
DFE BOM: DFE3.0 Annex A (1)
Capacity Used: 100% 100%
Noise Margin: 5.0 dB 6.0 dB
Output Power: 20.0 dBm 12.0 dBm
Attenuation: 36.0 dB 18.0 dB
Defect Status: None None

Downstream Attainable Data rate = 12216 kbit/s
I even get above the estimated figures for the widget at

The Actual rate has now been uncapped from 4525M before, yet I am still useful data limited to around 3.7M - why would that be?regards,Steve

Dear Mr Edwards,  Thank you for your time on the phone this afternoon.  As discussed in order to get our suppliers BT to investigate fully and implement a solution, we need some more speed test results:  Full instructions are below:  - Disable your Antivirus - Try a different device - Try a different router - Remove any extension cables  - Connect router to the main telephone socket  When you make any major changes to your set up like the above please ensure you leave it connected and turned on in that way for 72hours before you will see a difference when performing speed tests.  Please run the speed test again at BTW Speedtest  When the 1st test completes, please click the button labelled "Further Diagnostics". Once this test has been completed, the results are sent to the BT Wholesale servers. We can then access these.  Currently, BT Wholesale isn't showing any Further Diagnostic results which indicates the full test hasn't been completed.  Should the test fail, a new test will be offered. Firstly we need you to log into your router using a new browser window.  If you are using a router we have supplied.   Please see below guides for our routers:  Plusnet 2704n  TG582N  Thomson 585  If you are using a router you have purchased, you may need to consult the instruction manual that was supplied with your device.  When you have logged into your router, it needs to be set up using the below details:
Broadband Username: speedtest@speedtest_domain
Broadband Password: testing
Please then switch back to the BT speed test window and re-run the test.  If this isn't loading please try accessing the site through the IP address: http://217.32.105.42/ as the DNS servers may not work.  This will ensure we have tested your account speeds and also the BT network speeds so we can more accurately locate the problem. Please also confirm you are connecting to the router via a wired Ethernet connection and have no other devices connected that could be using any bandwidth.

BTs test page was not accessible from their test account login in the afternoon!! Unbelievable incompetence isn't it? Plusnet sends a test program to the customer and don't even check if BT's page will work or not!
Despite that, I got the tests done on my login, and completed the diagnostics page 2 to get sent to BTs servers, which must have given the info for the 3.8M issue, so by 9pm...
...Finally!! BT must have checked the results from the afternoon tests, so at 21:00, I retested and am getting 9.7Mbps throughput via the Vigor router! What a friggin rigmarole..!
