One thing I've noticed about FTTC is the lack of choice when it comes to FTTC modems, particularly with BT Infinity. Apart from using the old Openreach modems, are there any alternatives to that modem yet?
Surely it wouldnt take a company much technology to mimic the openreach modem?

Price ends up being pretty close to the cost of combined VDSL2 modem/routers and as separate Openreach modem and Ethernet router are rarely provided now the market is small.

AVM Fritzbox 3390 or 3490. Combined ADSL/ ADSL2 / VDSL router and wireless.
Nice piece of kit. Expensive but nice

Does it match the specification in the body and appendices of SIN 498?

It's German - I'm sure it follows all relevant EU specs

So what? Openreach have quite specific requirements for connection to their network, which will of course comply with EU regs but are likely to be more restrictive.
SIN 498. see Sections 2.4, 3 and Annex A.

I'm guessing you didn't get the humour in my post! 
I have one, and it works. If it stops working as a VDSL modem, I'll but the OR brick in and use the FritzBox as a router, until AVM provide an update for it to work.
They're good boxes, although mine just rebooted itself for no reason (for the first time ever)!

No joke for the Germans; they have previous for Quantitative Easing! After Versailles, they tried diluting their war debt by printing lots more money. But through the law of unintended consequences, they got Mr Hitler in their chump change! So maybe, as they say: " Gebranntes Kind scheut das Feuer!"

ASUS DSL-AC68U is a good bit of customisable kit. You just need to kill the 'spectrum' process via telnet until ASUS release a firmware which will fine tune that. Although it's suffered a negative reputation it seems the stability issues were due to the spectrum process presumably taxing the modem's resources too much, killing that process resolved it for me and many others. I run this on my connection and like it.

I'm not worried about you using one, but a little concerned that you advised the OP without any intimation that Openreach may at some time be unhappy about certain modems.
SIN 498 does say that if they find user kit interfering with the service to other users they may withdraw it from the offending user. I agree the chances are slight, but ....

Has anyone worked out what 'spectrum' was meant to do, vs what it actually did?
|
|

All ASUS said was this:
As for Spectrum feature, Spectrum while initiated, which is go to Spectrum page and click on the Scan button, then Spectrum process would start issue commands and fetch related data from xDSL chip, at this time due to gathering data might leads to higher CPU utilization, thus might lead to the higher CRC/FEC that you observed(however this is yet to be confirmed).
However, even without going to the spectrum page the spectrum process still somehow makes the modem become unstable and therefore needs to be killed via telnet for it to be stable. So my guess is that the spectrum process is querying the modem in the background (e.g. bitloading and SNR) but is doing so too often for the modem to be able to cope.

note I strongly suggest getting one with a BCM chipset.
The billion 8800AXL not on that list is also BCM.
|
|
|
especially the case that the asus DSL units are able to ignore UPBO and as such breach operating conditions.
|
|
|
Billion is very good as it come with BCM chipset!
My stats here with Billion 8800NL after 50 days ongoing connection!

If you're a sensible user then you wouldn't turn UPBO off on the settings anyway, by default it's auto.
|
|
|
|
There was going to be another new modem/router from Billion, the 8900AX, which is the same spec as the 8800AXL but with 3 external antennae but it's release appears to have been put on hold for the foreseeable future.
|
|
|
note the if, it seems a fair few on ocuk havent left it on auto. Assuming auto keeps it to dslam preference.
I have a theory one reason why the asus is unstable is that its possible it is ignoring many dslam settings than is visible, e.g. it may also be ignoring power mask settings which might be why is so much instability.
|

|

The instability, for what appears to be a good percentage, was caused by the 'spectrum' process. However, I believe the bitswapping algorithm might need improvement as ASUS tweaked with it and didn't use the original one from MediaTek, but people playing with the default settings might encourage instability (such as reducing the target noise margin or reducing the tx power offset). As far as I can tell the ASUS is observing things such as PSD's when I had spectrum running (unless it's outputting false bitloading and SNRM data - which I doubt).
