ADSL2+ and VDSL

Hello everyone.
I used to be a Verizon DSL subscriber and I have an ADSL2+ modem: Westell A90-750015-07. I moved and I can no longer get Verizon service, so I have Qwest now, which offers a VDSL2 signal.
Will my Westell modem work with VDSL2?

I do not know. Consider asking Qwest (your new DSL provider).

Optus ADSL2+ and WRT610n Quick Guide to setting up.

Hi all fellow Optus (australian isp) ADSL2+ and Linksys users,
I have a quick guide to setting up your new WRT610n with the optus supplied ADSL2+ Speedstream 4200 modem. This should solve most users problems with no internet connections, firewall rules not appearing to work properly etc.
It took me several hours of stuffing around and online researching untill I got these two to work together and have full firewall funtionality!
First up.... DON'T USE the LELA to setup the router! For some unknown reason, the laptop I used to setup the router, was configured by LELA to be a proxy and gateway, and unless that laptop was on.... the router wasn't passing info through it and back out to the internet! A full Reset of the Router was needed to clear this setting!
Now Lets get started.
BEFORE inserting the router into the network and connecting everything up, we need to reconfigure the Speedstream modem to FULL BRIDGE mode. NOTE! this will infuture disable the Web interface to the DSL modem, so changing to FULL BRIDGE mode should be the last thing you do to the modem before logging out. A full hard reset (little button) will restore the web functionality again should you need to put it back to normal.
1) Setting Speedstream 4200 to Full Bridge mode - This is necessary for the Modem to fully pass on ALL of the ISP settings. Such as correct gateway info, DNS info, "REAL" online IP address (not the generic psuedo 10.x.x.x number) etc.
- To do this, open your web client, Internet Explorer or similar. And enter the IP address 10.1.1.1
- Feel free to look around the settings of the modem but don't change anything just yet. Wouldn't be a bad idea to take screenshots of all the settings pages now like I did should I need to return it to original settings.
- The Webpage of the modem will open up and click on PPP - Take note (as in write this down!) of your "PPPoE 8/35" type which you'll select in the router later, and your Username for optus logon and password (you should know that or go looking for that paperwork that has your username and password that came with your optus Modem installer CD). You will enter all this login info in the router later as the router will do the logging in and take over from the modem!
- Next, click on Mode - You will see 3 options. For most, it will currently be on Optus Bridge. This mode enables a router inside the modem and is now to be replaced by the new Linksys you just bought. By Changing this to FULL BRIDGE mode, you essentially disable the modems internal router and turn it into a dumb modem (like the good old days of dumb dial up modems yey!)
- When you've changed to FULL BRIDGE mode, it will tell you the Web interface is now disabled. Close the window. And lets get to configuring the router.
2) Plugging everything in time!
- The Speedstream 4200 ADSL2+ Modem stays plugged into the wall as normal, but the LAN cable which used to go to your computer now plugs into the WAN port of the router.
- Plug the PC into one of the LAN ports of the Router also.... or if like me, you have a Switch that all the PC's use, plug that into the router.
3) Setting up the WRT610n (or similar linksys router)
- Open Internet Explorer/Firefox and enter the IP Address of the Router (Fresh install IP is 192.168.1.1)
- Username is "admin" and password is "admin" (you'll want to change this later I'm sure)
- OK now your in! We need to setup the internet account settings.
- Setup-Basic Setup page:- Internet Connection Type will be what you saw in the modem PPP page (you did write that down didn't you?). For me, I select PPPoE.
- The enter my optus username info and password
- click on Keep Alive (30 Secs).
- Then click Save Settings at the very bottom of the webpage.
It will likely ask to reboot.... let it do so
Now at this point:
- Your modem should have always been in Sync
- Your LAN IP from the WRT610n should be in the 192.168.1.100+ range? (I changed this later to put my IPs back in the 192.168.0.100+ range so I didn't have to reconfigure static PC's or printers around my network)
- Your Router should have reset about now and hopefully logged onto the internet through the modem.
To check all is working fine. Open the Routers webpage again and click on Status. Under the Internet Connection area, Click connect if it hasn't already connected for ya. This page should auto-refresh.
Check that the connection says Connected and that the IP addresses given in all the fields appear to be internet addresses (ie not 10.x.x.x or 192.168.x.x etc). If not, check that the status lights on the modem are all correct (you know how it should look when it's ok).
Open IE or firefox and check that you have internet!
It's important to make sure that the Internet IP Address in the Status page matches the one you get from http://www.whatismyip.com/. Because if it doesn't, then the Router isn't truely at the front of the Internet-Lan boundary. If this is the case, you may still have internet working ok, but the firewall portforwards may not work as seen in other forum posts around the net.
If it's OK, then Grab a Beer and Celebrate, you've just saved yourself 6 hours of hair pulling frustration!
SUCCESS!
Now, if your so inclined.... I would highly recommend changing Admin passwords, adding security to your Wireless connections, changing your DHCP to something your comfortable with or just leave them alone if everyone is server assigned IP's. I find it's a good idea to use the DHCP Mac reservation in the basic setup so I know each PC will get the same IP each time it logs into the router and thus makes Portforwarding SOOoooo much easier knowing the IPs don't change on you when the IP lease time expires if the PC has been offline too long.
Please feel free to comment on this, I'm pretty sure 99% apart from grammar is correct! Hope it helps many new and old users.
Have a brilliant day! and may the force be with you!

Adsl2+ and 1721

Hi, I?m using a 1721 adsl cisco router for my adsl 8mbps.Now, my Iinternet provider offers adsl2+ but new router/wic is necessary.
My 1721 uses a 1wic adsl to connect. Which is the new wic model for adsl2+ and 1721 that I need to buy?
Best regards

If you look at the data sheet for the 1721, you can see it only supports WIC and VWIC:

ADSL2+ and SNR issues

Hi,
Couple of weeks ago, I renewed my contract and subsequently found that I had been upgraded to adsl2+. With adsl max, I have always had a stable connection syncing at 5700+ coupled with a downstream snr of 6.0 and an IP profile of 5.0.
During the 10 day training cycle with 2+, my downstream sync remained fairly constant, although it went below 5696 at one stage dropping my profile to 4.5 for a few days, whilst the upstream steadily increased. SNR remained fairly steady at around 6.0 up and down.
At the end of the 10 days, my Downstream suddenly shot up to in excess of 7000 kbps, but my downstream SNR apparently dropped to 3.0! On checking the hub event log though, it gave the downstream snr as approx 6.0 at the time of the reset.
Thinking these snr numbers to be unsustainable, I did a reset to factory defaults, to resync, but got more or less the same results as below. The event log showing snr to be around 6.0 downstream and 3.0 upstream.
Is it possible that the snr margins are being displayed the wrong way around somehow? I have now left it 24 hours, fully expecting to lose connection and quite surprised that it didn't during the night when downstream snr was reporting itself to be 1.0 at times. Downstream FEC errors are also pretty high as you can see.
Any comments or help would be appreciated. Thanks in advance.

A lot of 21CN connections seem to have a low downstrean margin figure initially ....
I think it's because DLM sees the line as fairly stable ... and rather than apply more margin, even though it's below target ... it's preferable to apply slightly deeper interleave, because the error correction interleave affords doesn't decrease throughput, whereas rises in margin, however small does ...
21CN DLM uses multiple line configurations compaired to adslmax, and will apply the best solution for stability.
And if the line characteristic changes .... so will the solution.
I'd just let it "do its thing" ... it'll fine tune itself.

Airport Extreme 5th Generation and VDSL 2+

Hi Folks!
This question refers espicially to mac people in germany.
Is the Airport Extreme Basestation (5th Generation) good for using it with a VDSL 2+ DSL-Connection (50 Mbit/s) in a wired Network ?

Yes, Bridge Mode is the correct setting for the AirPort Extreme when it is connected to another gateway, or modem/router.
Connect an Ethernet cable from one of the LAN <-> ports on the 2Wire to the WAN port (circle of dots icon) on the AirPort Extreme.
Open AirPort Utility and click Continue to follow the guided setup to "create a wireless network" on the AirPort Extreme. The application should suggest Bridge Mode as the connection option during the setup.
Once you have the AirPort Extreme setup and providing a wireless network, if you don't really need the wireless network that the 2Wire is providing, it would be good idea to turn it off....since having two wireless networks in close proximity can introduce some interference issues.

Static IP and VDSL modem

I am upgrading to eFibre this week and already have a static IP address. Do I need to set the static IP adress somewhere in my router/modem? Thanks

Hi carrollf
A new modem will be provided for eFibre so storing the static IP in your old one will not be needed - If you take note if the IP itself and once installed contact technical support directly they will be able to re-assign it for you.
You can reach technical support via webchat at www.eircom.ie/chatnow or on free phone 1901

ADSL2+ and Upstream SNRm

Here's a question.
We all know that the DLM is pretty quick off the mark to raise your Downstream SNRm, in the event of multiple disconnects, in an attempt to stabilise the line. It has certainly happened to me on a few occasions! However, I have yet to see it do the same for the Upstream, outside of the normal 10 day training period.
During my most recent spate of disconnects, I noticed from the event log that although at each reconnect the Downstream sync speed remained fairly constant, the Upstream sync speed could vary pretty wildly!
This leads me to the uneducated conclusion, that the disconnects might be caused by the Upstream SNRm being set too low and the DLM incorrectly punishing the Downstream. Is this feasible?
If so, should the DLM not be able to automatically determine this? If it can't, can the Upstream SNRm be manually tweaked like the Downstream?
Just a thought.
Regards
Alan.

Hi Rodney,
Thanks for the reply. In my experience of banded profiles and I have now been banded twice, the downstream noise margins don't seem to follow the normal rules. But will return to normal once the banding is lifted. My latest banding was lifted this morning, after approx 3 days of stability.
I believe in my case the stability was aided by a low Upstream sync of just over 400 kbps and an upstream SNRm in excess of 10 db. This was how things were left after multiple disconnects over a 2 hour period. Firstly the downstream noise margin was bumped from 6 to 9 db with no luck. Then the banded profile kicks in, but apparently solves nothing, as disconnects continue for another hour and then suddenly stop. Upstream noise margin was not modified during this event, staying at approx 6 db, but the upstream sync fluctuated wildly from 1100 kbps down to 400 kbps.
This makes me believe that in my case, the noise event that caused the problem was Upstream. Hence the interest in the possibility of tweaking upstream noise margin. However, I'm the first to admit that I haven't really got a clue and its all a bit of a mystery to me.
Best of luck with the new Hub and the random disconnects.
Regards
Alan.

ADSL2+ and wierd Upstream issue

Firstly, I have been having some upstream problems. The numbers have been often under 100 kbps for the last month or so with lots of disconnects. The system has now put me onto standard ADSL upstream of 444 kbps. It periodically tries a reset but generally goes back to an unstable sub 100 kbps. Previous to this, I was on a stable 1000+ Kbps Upstream. I am not having any Downstream issues.
Second issue is even though I am showing latency type as interleaved, I am periodically receiving no FEC errors, but lots of CRC and error seconds errors. This is causing lots of instability and disconnects. I have noted that my ping is halved when this happens, perhaps indicating that I am actually on fast path?
The entire system seems really flaky at present and makes me think its an exchange problem although none are reported (Hereford). This has been going on for a month now and I'm starting to feel a little frustrated.
Any thoughts?

Have you tried connecting to the test socket at the rear of the master socket
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

Re: How can I find my cabinet number and when it w...

Hi,
I've been told by BT help chat that my address can get BT Faster Broadband but not Infinity. I'm connected to the Trowbridge SSTRO exchange which is apparently "FTTC available in some areas") Presumably that's to do with the distance of my house from either the exchange (2.2km) or the street cabinet (not sure which cabinet I'm connected to or where it is). If I've understood correctly, Faster Broadband uses the same fibre infrastructure as Infinity but because the speed can't be guaranteed as above 15Mb/s it can't be sold as Infinity. I am currently a Sky Talk subscriber so many of the BT utilities come back with an "number not recognised" error when I enter the phone number. So I guess I have 2 questions:
o If I take up Faster Broadband, how can I find out what speed I can actually expect?
o How can I find out how long it will be before I can get the full Infinity service?
I might add that a friend of mine in Trowbridge (1.1km from SSTRO) has full Infinity.
Thanks for any help, Midsomerjambo

Hi midsomerjambo,
BT Infinity and BT Faster Unlimited Broadband is just BT Retail's brandname for their fibre broadband service.
The reason why BT Retail say you can't get FTTC BT Infinity is because the FTTC estimation is below 15mbps.
However you should be able to get BT Faster Unlimited Broadband (FTTC) which is the same as BT Infinity FTTC but for those who have been estimated 15mbps or less on FTTC
BT Retail set a minimum speed required in order to get BT Infinity which is an FTTC estimation of 15mbps or above, if you have been estimated less than 15mbps for FTTC then you won't be able to get BT Infinity but may be given the choice of BT Faster Unlimited Broadband which still uses the same FTTC Openreach infrastructure and equipment .
What does it say for your landline number when you go to http://dslchecker.bt.com/adsl , If you don't have a BT Wholesale compatible number then you can check by your address by going to http://dslchecker.bt.com/adsl/ADSLChecker.AddressOutput (won't be as accurate as the landline number checker, but will give you an idea of the estimation speed)
FTTC fibre broadband uses VDSL or VDSL2 signals that travel from the FTTC cabinet to your property via the existing copper (sometimes aluminium) line. The further away you are from your FTTC cabinet the slower the fibre FTTC broadband will be.
However VDSL/2 signals used for FTTC broadband connection degrade far quicker in terms of distance than conventional ADSL broadband signal do.
Generally speaking if your landline is over 1500 meters in length from the FTTC cabinet to your property then you may not be able to get BT Infinity as you may not be able to achieve over 15mbps from an FTTC service, though may be offered BT Retail's sub 15mbps FTTC service called BT Faster Unlimited Broadband.
Here is a graph that shows the ADSL(G.DMT,ADSL2 and ADSL2+) and VDSL/2 (FTTC) signal with distance. Please be aware that all ADSL connections are depend on distance from local exchange, where as FTTC (VDSL/2) connections are depend on distance from your FTTC (DSLAM) cabinet. Though all connection types are also depend on line quality.
This graph is also just a general estimation of what the speed could be achieved and not the actual speed you will receive. Also your line maybe longer than you would think as it may not go the direct way to either the cabinet or exchange.
As to your other question How can I find out how long it will be before I can get the full Infinity service?
The Openreach Superfast Fibre Broadband Scheme is being rolled out, done and managed by Openreach for ALL ISPs/CPs so BT Retail (a communication provider/ISP whom operates this forum) does not have much input or say whether Openreach will improve the FTTC fibre infrastructre in your area.
Unless Openreach (who owns and maintain the fibre broadband infrastructure in your exchange area) either installs a new PCP and Dslam cabinet nearer to your property, or you order FTTPoD (Fibre to the Premisies On Demand) [not currently being supported by any ISP] which may cost you thousands, then I'm afraid it may be several years or so until the FTTC fibre infrastructure is improved by Openreach.
Hope that helps,
Cheers

1.4km from cabinet..is this the end?

My BT Infinity installation failed as I am 1.4km from where the cabinet has been sited.
I live about half a mile from the edge of the town
Now what?
Have I been abandoned for all eternity?
Are there any bespoke solutions?

Hi iaintaylor,
The Fibre infrastructure and "last mile" infrastructure that BT Retail and other ISPs use for their fibre broadband services/products (exluding Cable or KCom networks) are owned, installed and maintained by Openreach.
1) What does it say in the grid when you enter your landline number into the BT Wholesale database? http://dslchecker.bt.com/adsl . Please copy and paste the "Grid" with all the available services for your line into a new post.
If you don't have a BT Wholesale reconisable number then try your Address here: http://dslchecker.bt.com/adsl/ADSLChecker.AddressOutput
Remember to delete your landline number or address before posting it here.
2) FTTC fibre broadband uses VDSL2 signals that travel from the FTTC cabinet to your property via the existing copper (sometimes aluminium) line and can currently achieve upto 80mbps. The further away you are from your FTTC cabinet the slower the fibre FTTC broadband will be.
However VDSL/2 signals used for FTTC broadband connection degrade far quicker in terms of distance than conventional ADSL broadband signal do.
Generally speaking if your landline is over 1500 meters in length from the FTTC cabinet to your property then you may not be able to get BT Infinity as you may not be able to achieve over 15mbps, though maybe able to get BT Retail's sub 15mbps FTTC fibre broadband service called BT Faster Unlimited broadband (FTTC) if your line can cope with the VDSL/2 higher frequencies.
Here is a graph that shows the ADSL(G.DMT,ADSL2 and ADSL2+) and VDSL/2 (FTTC) signal with distance. Please be aware that all ADSL connections are depend on distance from local exchange, where as FTTC (VDSL/2) connections are depend on distance from your FTTC (DSLAM) cabinet. Though all connection types are also depend on line quality.
This graph is also just a general estimation of what the speed could be achieved and not the actual speed you will receive. Also your line maybe longer than you would think as it may not go the direct way to either the cabinet.
There is a thing called FTTP on Demand (FTTPoD) where FTTC areas can request to get FTTP installed to their property if their exchange has been allows FTTPoD (though this is not supported by any ISPs at the moment), though may cost you thousands if you go down this route once ISPs take up this FTTPoD service.

Hi
Can anyone answer this question:
How how far is too far away from a cabinet to get Infinity ?
Thanks
Ollie

Hi again ollie44,
BT Retail who offers FTTC (Fibre to the Cabinet) BT Infinity which is their brandname for fibre broadband, to customers who are estimated 15mbps or above for FTTC.
You can still get FTTC fibre broadband from BT Retail if you are estimated under 15mbps for FTTC though the product is called Faster Unlimited broadband.
FTTC fibre broadband currently enables a upto 80mbps broadband service, though this will depend on how far away you are from the FTTC cabinet and the quality of your landline.
FTTC fibre broadband uses VDSL or VDSL2 signals that travel from the FTTC cabinet to your property via the existing copper (sometimes aluminium) line. The further away you are from your FTTC cabinet the slower the fibre FTTC broadband will be.
However VDSL/2 signals used for FTTC broadband connection degrade far quicker in terms of distance than conventional ADSL broadband signal do.

Hi moshandy,
I'm also from Barnsley and been waiting for information on this, but unlike you I'm in an area that only has max 2mb but most of the time BT states 1.5mb even after going to ADSL2+
According to Broadband CS the exchange is already ADSL2+ activated, even though BT and most checkers say it's not. BT Infinity was also supposed to be activated soon but BT have pulled all information for that as well.
But if you check the BT Wholesale ADSL Checker it states our exchange is activated for MaxADSL, ADSL2+ and BT Infinity.
Now I'm not sure what part of Barnsley you live in, but I'm in Dodworth which has recently had fibre laid and connected to the BT cabinets by DigitalRegion. They may have also started laying the cable in your area as all of Barnsley is going to receive the service.
This should have also been made available today but currently they are still awaiting for ISP's to sign up to them, and they are guaranting 25mbps speeds all the time.
Now according to BT it's down to Openreach if and when BT can start using both the ADSL2+ and VDSL technologies our exchange is already prepared for. It could be a week or it could be another year, as the exchange upgrade was originally planned for Nov 2008 and was put back to now.
Now Plusnet who are owned by BT also state our exchange is ADSL2+ activated, so not sure if this is BT preventing us consumers from using the technology that is already in place at our exchange, and the exchange + cabinets have been fibred for more than 2 years as Dodworth and 6 other locations around Barnsley where used for the original trials back in 2005 I believe for the fibre network.
I know when speaking to CS yesterday they offered to move me to ADSL2+ but I don't want to move to that as it's no better than what I already get (and to be honest is below the government recommendations of 2mb minimum to all households), I just want to move to the VDSL service asap.....

In the example, XA, XB, and XC, the X in the first position indicates a one-time (short-lived) release originating from the major Technology (T) train. The letters in the second position (A, B, C, D, and so on) are sequential letters used to differentiate the releases.
