Ah, of course. Sorry .

Yes, good point forgot about that. I suppose that's a very good reason why they haven't rolled out vectoring, even two Huawei cabs couldn't vector between each other.

Yes, they can. Node-level vectoring.

Ah so they do, and I can see its been around for years.

You can't have Vectoring where there are 2 different DSLAM's situated.
The ECI would kill the Vectoring on the Huawei in that situation.

OpenReach would need to route different cable bundles to 1 DSLAM and other bundles to the other DSLAM to isolate them.
They would then need to ensure those cable bundles stayed isolated at every single stage of the D-Side.

That leaves you with the same problems as ECI line card Vectoring. Order systems aren't designed to cope with this kind of thing. It would be a logistical nightmare to organise if it was even possible.
Maintaining it would be even worse.

Can anyone explain to me what a �bundle� is? I�ve never heard this term in the industry, and it only seems to be used on internet forums. Same as pit or chamber when they mean jointbox or manhole.

Surely a bundle is just a cable? 50 pair, 100 pair, whatever?

Well not everyone reading this works in the industry or know all the technical terms OpenReach use.

Rather than saying multi-pair cable it's quicker and easier to say bundle.
I've heard engineers reference "cable bundles" in the past.

Amazingly enough I've never heard anyone ask what a cable bundle is, or what a chamber is for that matter. Especially not an OpenReach engineer.

OpenReach actually refer to them as chambers in most of their developer documents.

A little petty and pedantic if you ask me

edit: to add, the term "bundle" is used all the time in "the industry" when referring to crosstalk and vectoring, the topic being discussed.

I�ve never heard an engineer refer to a bundle. If it�s a 50 pair cable then that�s what you call it, if it�s a 100 pair then that�s what you say!

I think chamber and pit came from the cable industry. They�ve always been called jointboxes inside the company. Anyone that joins and calls them pits gets swiftly corrected �It�s a jointbox not a pit!!�

Maybe they use chamber for developers so that they�re using the same terminology as Virgin Media. It wasn�t an attack on you, I�m just curious to know where all of these terms are coming from, that�s all. Some of your posts make me think you do actually work for Openreach though, but then bundle and chamber threw me off!
