Well Ive gone and done it too - Goodbye O2, welcome infinity


[link to this post]
 
Made the switch to BT infinity although its not being installed until 7th sept 8-1pm. Managed to get the 3 months free offer too.

Been with Be since it launched then we moved house and went to O2. But now, the time has come and it doesnt look like Be/O2 will be rolling out fibre anytime soon. Cannot fault the service from Be and O2 though. At our old house got a solid 21 meg connection and this house gives solid 13 meg.

We are on the London Ponders End exchange and estimates show 40 meg down 10 meg up on infinity. I can see the fibre cabinet at the end of our road and its roughly 80 - 90 metres away.

If I'm honest, I am a little nervous about leaving my old O2 legacy connection for BT after reading all the horror stories but I'm hoping things go well for me.

Well, wish me luck everyone. I'll update with how things go next week.

Cheers

Today is the day. Engineer should be on site anywhere between 8am to 1pm.

Does anyone know if the modem and router have to be in the same room? I was thinking about having the modem in the hallway where the telephone master socket is, then running cat 6 cable into the living room where I'd like to site the router. Also, do you think there would be any issues in me extending the power cable for the modem. Im thinking about cutting the cable and adding a 3 meter section of wire to extend the reach - thats what i have done to my o2 router, been fine for years.

I'll update this thread throughout the day - hopefully it all goes to plan and he/she turns up

No they don't. The link between the modem and router is Ethernet so will happily go up to around 100' away.
I'll put money on the engineer saying they have to be next to each other, though!

The link between the modem and router is Ethernet cable with a specification of 100 metres maximum. So no problem.

Re the power cable I see no reason you shouldn't extend it as long as you do a proper job. For instance one of the two or three-wire proper connectors, either hard-wired or plug-in (done with the male at the modem end).

I wouldn't add a section in the power cable, meaning two connections needed. I would cut the mains plug off and add a single length from the mains socket. Don't forget to use the original (rating/strength) fuse from the modem's plug. That's how we run the toaster incidentally.

I've just finished running ethernet around the house to all the rooms. All hooked up to a cosco gigabit switch and then into the BT HH3.

So far it looks pretty good on the broadband side of things. My caller ID on the landline has stopped working altogether, although I have been having some issues with it for a few weeks. I'll leave it until the training period has passed before reporting it as a fault as I'm concerned that they may do a few connects/disconnects which may mess up the DLM.

The engineer was a decent chap. He didnt have any issues with me putting the modem in the hallway and the router in the living room. He even gave me some jelly crimps to use to extend the AC adapter for the modem and let me borrow his jelly crimp pliers.

I'll do another speedtest using the BT speedtester later on in the afternoon and see what happens.

Caller ID - it may not be a fault on the line. There are certain phones and display devices that will not display the incoming data even if it is enabled. It was well documented when ADSL was introduced and there may be further problems with it with VDSL.

I have some phones that display and others which do not.

Caller ID can (providing you are registered for the service) be switched on or off by you. There is no need to get BT or an engineer involved!!

You can check if caller display is active on your line by dialing *#234# if you want to turn it on dial *234# and to turn if off dial #234#

MHC - Thanks for that info. A bit odd that it was working fine on adsl2+ for about 2 years and about 4 weeks before the fibre change over, its gone funny. Anyway, I think its about time to get a new phone now, might as well as everything else is new now, lol.

Thanks also for that info about calling *234# to check the status of caller ID. I did try that just now but it says "sorry, the service requested is not available". Any ideas?? think i may just leave it until training period is over and line settled before reporting fault.

If you are getting that message then there could be a fault.

Call 151 and ask them to check it is enabled correctly - sorting that at the top level should not affect the Infinity service.

Sure you dialled the correct sequence? If you dialled *#234# and it said the service is not available, then try turning it on by dialling *234#. If it still says that it isn't available then there is a problem which will need BT to sort at their end. As MHC says, Infinity shouldn't make any difference as such.

Yea, tried that too Gary. Still says "sorry, the service requested is not available. thank you for calling, please hang up" The guy at the call centre assured me that everything is turned on at their end too. Im thinking I may disconnect the modem after the training period whilst they are looking for the fault until they fix it. I really dont want to upset the DLM.

Who says there is a 10-day training period on FTTC?

I've seen a few posters talk about it as a fact, in the same way as you, but have never seen any official statement quoted. I would not count most ISP 1st-line support as "official" either.

The more that say it the more it becaomes a possible "FTTC myth", from pure repetition.

FTTC looks to me as though it just settles fairly quickly, if not immediately, but may degrade over time as crosstalk increases. The DLM is not the one we are used to on ADSLx.

I'm not for sure about the DLM Robertos mate. I'm sure I read somewhere here that there was one. And also, looking at the 2 speedtest result I have put up above^, it looks like the line is speeding up since installed this morning - although I may be wrong.

Yea, I'm with you on that, first line technical support should always be taken with a pinch of salt, or a heap maybe.

TBH, on pulling open a few pages, there does seem to be a very very slight lag compared to my O2 legacy connection which I left. Also, youtube buffering seems to be slower although it may be a congestion issue. We use the internet quite a bit in our household and I really hope I havn;t made a bad move with this. Time will tell I suppose.

If you are getting that message it is a problem at the exchange. The database is saying you have it turned on but the switch is telling you that the locally held data is saying do not send CLI to the customer.

Try turning it off #234# then on *234# and repeat a few times before using *#234# to check

I didn't say there wasn't smile. I said it was a different one.

The DLM on FTTC is from Openreach and runs on the cabinet DSLAM. It is far superior to ... the DLM on ADSLx from BT Wholesale is from BT Wholesale and runs on their DSLAM/MSANs at the exchange.

I queried the existence of a 10-day training period on FTTC, and still do. As has been noted, your IP Profile is 38717kbps, the highest possible. Any speed fluctuations are down to your ISP and what you are doing.

Appologies to the OP for going OT.

RE the training period, the post here may be of interest: http://community.bt.com/t5/BB-Speed-Connection-Issue...

Apparently the WBC FTTC Handbook states that the line is "allowed to stabilise during the first 10 days"

My theory is the stabilisation period lasts for 10 days but the line may stabilise before then if it's stable at full rate, yet it will remain in stabilisation mode for the full 10 days, after which the normal DLM starts.

Re: Well Ive gone and done it too - Goodbye O2, welcome infi


[re: Croftie] [link to this post]
 
The two sources you give there are examples of "myth-speak" I'm afraid.

The more important is that the WBC handbook, which you don't link to so I haven't read, is by definition not authoritative despite its title. As I have explained, the DLM on FTTC is nothing to do with WBC. Such documents are frequently written by "Technical Authors" whose job is to "interpret" what they are trying to explain, and often make assumptions that in this sort of situation that what was true with a similar product that they are familiar with is true with the new one. In other words fail to realise that the product is not a development of an existing one by a different company, but something totally different performing a different function.

The link you give to a post by RogerB, a guru, is highly suspect and I think based on such as the above. Note that in an earlier post he badly misspells "metallic", not something I would expect from anyone involved technically with Openreach products and terminology.

I have had a quick look through the Openreach description of the GEA service. Note that in the extract below that "train" refers to the process of negotiation between user modem and the Openreach cabinet DSLAM when establishing the connection, not a "training period" as applied to WBC products by the BT Wholesale kit. Similarly "trained up" means "connected and sync established". There is no mention in this of a training period of any length.

2.2.5 Dynamic Line Management
Dynamic Line Management (DLM) is employed in GEA-FTTC. DLM constantly
manages lines to maintain a target stability. It does this for as long as the product
exists.
At provision, the line is put on wide open profiles, allowing downstream line speeds
of up to 40Mbit/s, and upstream line speeds of up to 2Mbit/s or 10Mbit/s depending
on the upstream product option selected.
On the first day of operation, DLM will intervene if severe instability is detected.
Otherwise, DLM will wait until the day after provision before intervening, provided
that the line has been trained up for at least 15 minutes during the preceding day.
If DLM intervenes it will set a capped profile with a maximum rate and a minimum
rate, where the minimum rate is set at approximately half of the maximum rate. The
purpose of the minimum rate is to ensure that the line does not train at a rate which is
significantly below the level the line should be able to achieve. If this happened, then
the line is likely to remain at a very low rate till a re-train is forced by the user
powering off the Active NTE.
Note that the upstream throughput is also constrained on the DSLAM to the upstream
rate requested in the order, ie 2Mbit/s or 10Mbit/s, so even if the upstream line speed
is higher, the upstream throughput is constrained to the level ordered for the product.

I assume you are talking about "the WBC FTTC Handbook". Unless you have given an incorrect title that is self-evidently not an Openreach document. It cannot therefore be relied upon.
Looks like you read back through the link I gave you which quotes more interesting reading from SIN 498, available here: http://www.sinet.bt.com/498v3p2.pdf
Having read the whole of SIN 498 myself, before my earlier reply to you where I quote from it, without having read back further in the linked thread once I established RogerB was unlikely to be reliable so I am unaware of what others have construed from it, there is no mention whatsoever of a 10-day training period.

SINs are the only reliable documents easily available to the public.

OK, I've now found a reference to the "WBC FTTC Handbook" in SIN 495, dated November 2009. Also I had missed RogerB's quote from it in the thread you linked to.

I reiterate I have grave doubts about how correct that will be, as explained previously. In particular it is certainly out of date as there is no 15Mbps floor on GEA now.

Bad news this morning, picked up the phone to make a few calls and can hear some serious crackling -rather loud. Popped over to a neighbour to borrow their phone and getting the same thing. Plugged into the test socket behind the lower faceplate too, all the same, fault still there. So I called 151 reported the fault and she's doing a line test for me now. Should hear back in 10 minutes. Think this may have something to do with my Caller ID not working.

Bit worried now incase the modem downsteps due to the noise and goes onto a lower profile. Currently on 38717 / 10000. I expect if the noise gets any worse, it will be dropping down a peg or two. Is this right? Any advice on what else I can do?

Not aimed at RobertoS directly, but more of a general conclusion to all...

In the WBC DLM FAQ document we have, it states:

"Does DLM run on all WBC lines?

Yes. The BT Wholesale variant of DLM runs on ADSL 1 and ADSL2+ WBC Lines. FTTX services falls within the Openreach DLM domain."

In the FTTC Handbook (dated January 2011) id doesn't give out DLM specifics at all, but says:

Following installation of service, the line will be allowed to stabilise during the first 10 days after provision and a Fault Threshold Rate (FTR) will be set at 5 Mbit/s downstream for services provided at up to 15 Mbit/s downstream or 15 Mbit/s downstream for services provided at greater than 15 Mbit/s downstream.


Also:

Dynamic Line Management (DLM) will be employed to manage line performance to maintain a target balance of speed and stability and is based on amending key variables of a line, specifically: Impulse Noise Protection Capping Interleaving (Please note - there is no order option to remove this). By altering these individual characteristics the line performance is adjusted to meet target stability. The Stability Options offered by BT Wholesale have been mapped to align to the DLM policy options that BT Openreach provide. (Please see below re Maintaining Line Stability)

Line stability is crucial to service quality and to the End User experience and WBC Service provides WBC Customers with more flexibility and more control. WBC Customers can increase or decrease line stability by sacrificing or gaining speed.
WBC Customers and Reseller Customers can choose appropriate line stability profiles that are related to the different needs of End User applications.
WBC Customers and Reseller Customers can change the stability option online as necessary to meet their End Users‟ changing requirements.

Standard
Allows a CP to offer a higher line rate, by allowing the line to have a lower stability target than the Stable Option provides.

Stable
This setting - aims to keep the line working with only a few errored seconds and retrains each day.

Super Stable
This option allows CPs to offer a higher level of stability by using increased error protection. The line will work at a lower speed than the Stable option and at times it may give rise to increased latency.

Note Signal to Noise ratio will be set at 6dB for all DLM policies - applies to FTTC only as I know it doesn't do that on WBC.

which are the same as on ADSL I guess although they may work differently.

No mention of Interleaving anywhere although I do know it can be on or off.

So there is no 100% clarification about the initial training. I would take the SIN as being correct as this is what specification the product conforms to.

You've done all the right things and all you can do. Just wait and see.

Audible noise doesn't necessarily mean there is noise in the VDSL2 spectrum. Think about it the other way - fixing audible noise stands a good chance of correcting broadband noise, just because there is a fault on the line that could also be causing broadband noise, but we know you can have broadband noise without any audible. The converse is also true.

The cause could even be between the old cabinet and the exchange, where my line is very dodgy, and that seems to get filtered out at the cabinets.

That was one of the reasons I switched to FTTC which I don't really need, as my ADSL2+ service frequently got destroyed by it, and several engineers in the area have said finding decent connections is difficult. Mine having been switched to another (speed inferior) pair in the past when it failed completely.

On FTTC there is no broadband effect when the phone goes odd. You could very well be in the same position.

That's brilliant James, thanks smile.

Plenty to chew over and interpret, but my initial reaction is that BT Wholesale has tweaked their own DLM to run on top of the Openreach one, with two main things apparent from those quotes:-

1) They retain a 10-day period after which they set the FTR, note no MSR, this being for the purpose of their existing fault reporting systems, but that this is nothing whatsoever to do with the line rate itself being controlled at the noise margin or IP Profile level, which is within the OR DLM. That sounds perfectly reasonable;

2) Similarly, for ISP control they have "mapped" line setting facilities to pass through to the actual ones operating within the Openreach systems. That makes good sense, as otherwise there would be options present but not available.

It seems to me that the WBC DLM therefore doesn't have any active role, and the 10-day period which I now accept does exist on FTTC is in fact irrelevant to anything. It's just a convenience to simplify the mods to cater for FTTC whilst maintaining it for ADSLx.

In particular, the "line will be allowed to stabilise during the first 10 days " is a mere hangover wording, as this DLM takes no action whatsoever. Any line control adjustments occur within the Openreach DLM as quoted in earlier posts. It just means the FTR is set to the predetermined value at the end of it rather than immediately after installation, simply because that's the way FTR setting is coded in for ADSLx.

The latest on the caller ID issue is technical support say they have removed the service from the line yesterday and will activate it again by Monday. TBH, I dont think they know what is really up with it as they sound really stumped every time I speak to someone about it.

Ive also noticed the throughput on the infinity side of things to be on the low side in my opinion. On average its hitting about 33 meg on the 38717 /10000 profile - Im not too sure what to expect if im honest. Perhaps I need to watch it over the coming days. What I do notice though is a slight lag when pulling up webpages. This was never there before when I was on O2.

I'll update on monday on any progress.

Cheers/.

Also, has anyone noticed the new speedtest available on speedtest.bt.com?

Theres a beta option now. Any thoughts?

That's interesting. Back-to-back tests it gives 3Mbps or so more than the old one. Downloads a lot less data.

A lot easier to use, but I hope it is just a test of concept. If we lose the IP Profile info it will be a retrograde step in my opinion. Although if the IP Profile is going to track the sync rapidly on all connections, as it is now doing on some, I don't suppose it matters too much.

I think you should start a new thread in General Broadband about it. There's quite a thread about it already in BT Wholesale Implementation forum.

PS - it's speedtester.bt.com.

I also have the total broadband package (with, allegedly, three free calling features - one of which can be caller ID).
Unfortunately I wasn't aware you have to order these at the time of placing your phone line order.
Thus; I have no features and (apparently) can't have them until the contract period expires!

What possible harm could come from BT actually giving us some customer service (for once) and enabling our three FREE calling features?

Starting to remember why I dumped BT all those years ago.

EDIT: I remember saying (to Orly) a little while ago, you get what you pay for!
Don't ever remember having this much trouble asking for caller ID and 1571 answer phone with Sky (in fact, I seem to remember being able to order these online).
BT's stupid online systems won't let me select any of my three free calling features.
Their website even says
BT Answer 1571 voicemail and other Calling Features can be added to your line
before it helpfully says "We're sorry...
We have noticed you already have one of our great package deals." (when selecting the "already with BT? - Change your calling features" option).
What; so as I'm already on a plan which has three free features (which are not yet enabled) I can't have any?
If it's such a "great package deal" why the Hell can't I have any calling features on it?
