I have recently got FTTC installed but my line speed is a lot less then expected. If you can answer a few questions I would appreciate it.
1/ I have had a line test done with plusnet, ie errored second etc. Do the tests just work to the cabinet of do they go all way to the BT modem.
2/ Can you plug an ADSL2+ router into your FTTC socket and wil it work in ADSL mode. I ve been told this will work but obviously at ADSL speeds. Will I have to set my router to PPPOE to do this?
The reason why I want to do this is I've had problems from the cabinet to my home before (i suspect RFI) and I can see it with an ADSL router.

Have you carried out a speed test using the BTW speed tester? If you click the Further Diagnostics button after the first test stage and complete the second stage you will see your BT IP profile. For the downlink, this value should be 0.9679 of your actual VDSL sync speed.
And finally, if you want to check your VDSL line stats, your only options at the moment seem to be either to buy a router with a built-in VDSL modem (there aren't many - mainly Draytek and Fritz!box), or buy an unlocked Huawei VDSL modem from eBay (the v1 modem used by BTOR), or if you have the Huawei version, you can hack it.

I wasn't sure if the Cabinet equipment could handle ADSL as well as VDSL hance my query.
The reason I'm trying do this is that since going on to FFTC my sync speed is a lot less than expected. I suspect the problem lies with the link from my premises to the cabinet as this has been a problem in the past (not that BT did anthing about it at the time)
At least I could get line stats with my old Netgear router.
What's the betting I get fobbed off by the BT engineer again when he visits

The title of your post is misleading by the way, because you were actually talking about an ADSL(2+) Modem/Router. You can actually use any Router of your choice on Fibre, but you need to use a vDSL Modem - note the distinction. The DSLAM in the Cabinet will not like an ADSL modem connected to it!
When your Fibre was "installed" the engineer should have carried out a series of tests which would include the Copper all the way to the exchange.
As has already been mentioned, use the Diagnostic part of the BTw Speedtest to monitor your IP Profile which should be constant. And rebooting the BT Modem is not recommended either unless absolutely necessary.
Hacking the Modem is not recommended unless you really know what you are doing. Best to buy one off eBay as has been suggested when you can play with the firmware on that. Bricking the BT one is likely to land you with a large Bill!
vDSL stats are quite hairy, not simple like ADSL, you should really do some reading around before even thinking about doing anything, OK if you have the technical ability.
HTH.

I think it a little unfair to say that the OPs title is misleading, What they wanted to try was clear to me.
I was also under the impression that any router had to be capable of PPOE to handle fibre (ie a cable router).

And a lot of Modem/routers are capable of being set up as switches with PPPoE, ok there will be some that can't be, and you lose a LAN port if they don't have a WAN port

All multiport modem/routers contain a switch that can be used without any configuration needed (though the usage described may require a managed switch)
Using a TP-Link Archer VR600 modem-router.

Quote Any remote Broadband tests on your Fibre connection go all the way to your Modem at home from the DSLAM in the cabinet.
The reason for this question is that with ADSL ISP's where not able to detect errors occurring from the cabinet to the modem. I had high CRC errors on my old ADSL that were generated at the D stage and could only be identified when an engineer tested the line from my home to the cabinet. Since BT now own the modem I wondered if they can put my modem into a diagnostic mode to test the link from my home to the cab. If you seem to think they can now identify this then at least when my line goes flakey again (has done 2 times in 3 years) It will be easier to identify.

Really? everyone who replied seemed to know what I was saying, I didn't want to make my query too technical.
Quote because you were actually talking about an ADSL(2+) Modem/Router. You can actually use any Router of your choice on Fibre, but you need to use a vDSL Modem - note the distinction.
Yes I Know my old "router" has an ADSL (2+) modem as well as router and PPP login part to it. When I ordered fibre I must admit I thought I'd get a Router/vDSL modem. I didn't know that BT supplied the modem seperately (step backwards to Speedtouch USB IMO). I worked out that a modem was needed as soon as the Plusnet router arrived with RJ45 sockets and no RG11 to be seen. Now I need 2 boxes eating into my electricity bill and 3 Boxes if I need a wired gigabit Ethernet.
Quote The DSLAM in the Cabinet will not like an ADSL modem connected to it.
And that's the only part of my question I needed to answer too, as I wasn't sure in the DSLAM in the cab could was multicompatable with ADSL as well as VDSL. The answer was pretty much answered from the first reply.
Quote Sorry I wasn't intending to appear unfair, just to be clear for those less well informed Not everyone appreciates or understands the difference.
I am new to fibre so that's why my initial question was a quick and simple one, I didn't expect the thread to get into a technical discussion on the perceived depth of my knowledge.

Well I had no problems with telneting into my trusty netgear DG834G to set the SNR and get router stats. Even simpler when the Routerstats program did all the work. DGTeam did some pretty good work with the firmware too.
Currently got a CPI modem and about to get a Huawei one from fleabay. If I need any help then I will definitely ask.

And the answer is fairly straight forward. With ADSL the equipment (DSLAM or MSAN depending on the technology) is in the exchange. The Cabinet is nothing more than a connector box. So Remote testing can only work from Exchange to End User. With Fibre having the equipment in the Cab, Remote testing is from Cab to End User.

needs no answer since it implies that the cabinet is, as you say, nothing more than a connector box, yet you still seem to give an answer even tough you earlier confirmed that diagnostics could be done to the end user. I was mearly stating the reason for asking the question in the first place.

I apreciate you are answering questions so others can understand but I fail to see why you need to answer the same question twice, especially when I didn't even ask the question again. It's a fine line between being helpful and patronising....
sheesh, I only asked a few questions ::).

It seems that maybe we have got on the wrong foot. probably best for all, including me, to acknowledge that maybe I should have not jumped to some conclusions but it swings both ways.
Anyway, my huawei modem should arrive by he end of the week so I will install it and see if I get a better sync rate. I need some info on the way DLM works on fibre. I have read a few threads on this forum on DRM but a lot of it seems to conflict and I have not been able to find a definitive answer on how it functions. You seem to be a knowledgeable person so I'll start a new thread when I get the modem.
till then.
