BT Vectoring


[link to this post]
 
Does anyone know the possibility of BT doing vectoring anytime soon?

I know they are doing phase 2 trials, but is there anything that would prevent a roll out?

Is their DSLAM equipment vectoring capable? Does it need line card swaps or new kit? I know they have Huawei and ECI DSLAMs and heard that the M41 ECI's would have to be upgraded to V41s.

Also are there any other limitations like CPE issues? Are existing CPE Vectoring capable?

Thanks!

That's all I've read.

I think the ECI bFocus and the Huawei HG612 are both capable CPE's but there are still questions around third party (e.g. TalkTalk, EE, Sky and BT's routers) - and the implications of someone using a non vectoring aware router on a line in the middle of a vector bundle. Does everyone suffer?

Vectoring may show that "wires only installs" was a mistake, and using the Openreach supplied modems should have been always the case. That would have made Openreach's job much easier for upgrades.

With the OR modems posted out by the ISP.

Yes that would have worked, and reduced the cost, but kept the compatibility. I think this is how DSL works in the USA - but in the USA you only generally get a handful of DSL providers in an area, as there is no wholesale network equivalent.

Trying to have "certified" modems (e.g. BABT green sticker equivalent!), and suchlike is the road to chaos. Ethernet should be used as the industry standard interface and end users will have to put up with having two boxes.

But OR will make money from certifying them and save money by not supplying modems tongue.

I expect word will get out, or a list of tested/supported kit will emerge.

ISP supplied kit has to support vectoring to be qualified for use with the Openreach network.

OP - Openreach are running at their usual glacial pace. It will get done when they can be bothered and the group have some cash spare from buying footie games for BTSport. (I call them BTCoins, each one being the cost to BT of rights and production of a single match.).

The business case for vectoring isn't the strongest and in some cases gets more expensive still - sites where there are 2 DSLAMs, something that probably shouldn't have happened, need a little more work. I am aware of one site which has an ECI and a Huawei serving a single PCP. Should be fun.

Yes, the ISPs can be worked with, but now its essentially "wires only" (ie, I didn't take the PN router) there is zero control of what is sold and connected to the lines. Just like ADSL.

Just like xDSL everywhere. Even without wires only people were still using their own kit.

Compatibility issues are nothing disabling ports connected to non-compliant kit won't cure. The SIN is quite specific regarding what is required.

I be surprised if openreach start turning port's off, maybe they will have an automatic system that cuts a port off if it detects vectoring failure, but if they don't I don't think they will bother manually doing it. But hopefully I am wrong.

If Openreach did it the way Japan and South Korea has done in the past with xDSL variations then we would expect there to be a massed outcry as they react and tweak settings to cure the issues.

Left hand up for a national try it and see effort i.e. modern version 1.0 beta software release
Right hand up for a slow but measured engineering approach
