Interesting article about copper/cable, vectoring and g.fast

As you say, very interesting.  They haven't come up with a processing solution to copper theft though !

Reading that link, it would appear its pretty much in its infancy with Telco's and not all the trials went swimmingly ?? Another example of individuals mistakenly seeming to know more, than the actual industry experts.

Perhaps if various arms of BT were somewhat more open & transparent for the benefit of the no doubt tiny minority of EU's who are actually interested in such matters, there would be far less assumption, supposition & outright wrong conclusion drawing?

It would also perhaps not be too bad an idea to occasionally filter some details down to the 'Field guys' as I'm sure it would help for whenever they end up visiting an 'interested' EU.

FWIW, here's a couple of examples of when significant changes to service were implemented that caught EUs (& apparently ISPs) by surprise (including Plusnet - actually owned by BT):- 

*Change from 8c profile (Max DS sync speed 40 Mbps / US sync speed 10 Mbps) to 17a profile (Max DS sync speed 80 Mbps / US sync speed 20 Mbps)
*Revision of 17a DS band plan tones from Maximum of 1939 to 1959 (Huawei DSLAMS)
*Very recent HG612 modem firmware updates, including revised band plan tones & apparently switching SRA on (Seemless Rate Adaption)

Gentlefolk,

Did not some of our esteemed cognoscenti suggest that vectoring is not directly compatible with the MSANs installed ?
I thought it had been suggested that Huawei MSANs require an additional module installed and ECI ones require a new processor board.
All of which would be relatively expensive and time consuming.

Whilst I'd be surprised if laboratory testing data was not employed by some marketeers, it seems there are others who are yet to be convinced that it is the answer to BDUK's prayers.

Kind regards,

Before vectoring can be implemented:

• "Hauwei cabinets" will need to be fitted with a MA5603 sub-rack.
• "ECI cabinets" will need to have the existing M41 MSAN removed and replaced with a V41 MSAN.

Not something that can be done without cost nor without disruption to existing services.

b*cat performs his best Japanese-style bow to acknowledge Our Leader's findings. 

It has been quite some time since I last "had a fight" with the ECI web-site when trying to find some information. 

Now I wonder what choice Beattie will make for her "ECI Cabinets"? 

[kitz]

I found it by searching "ECI, vectoring, line card", as Id heard before it was possible, but it wasn't always practical as ports/pairs may be wasted. 


>> Now I wonder what choice Beattie will make for her "ECI Cabinets"?

I suppose it depends how much and how often they want to avoid this :-

It becomes necessary to send technicians to the street cabinet to perform some cable management.

Its a shame theres no module that could be slotted in to the existing M41s rather than having to replace the whole dslam. 
If anyone had the weight to get ECI to provide such a thing then youd think it would be BT...  but since theres no news on this front I assume that its not possible.

Theres an awful lot of ECI cabs out there that are going to need to be upgraded

Nods in agreement.

If this is the case, wouldn't it be cheaper for OR to roll out 30a and Vecotring in one big go?

TBH Im not sure what changes would be required for 30a..  and even if 30a would be beneficial aside from those very close to the cab, so Im not sure what % would gain from 30a.
I would have thought vectoring though would bring benefits to more of the population?  Particularly when we on this forum are beginning to see very large decreases of speed (circa 15Mb) once the cabs start to fill up.

According to Asbokid and discussions in this thread, the Huawei's just need a firmware upgrade for vectoring. 
A very quick scan shows mention of a sub-rack and ignitionnet mentions cable re-arranging for 30a. 

I dont have time to do any digging but perhaps in the Huaweis there is an easy 'slot in' type card that can do this?   Kind of like sticking a sound card into a PC?  I dont know, so if anyone has time to do a bit of research then please do share.

I'd already mentioned above that its seems to be a failure of the M41's that you cant just slot in new modules.
The V41s should already be compatible with 30a and bonding.

The question remains how BT will handle the ECI cabs.  Will those users get line card vectoring and BT burden themselves with juggling copper pairs, or will they stump up and get V41s.  Only they will know the costings.

....and to all those who now complain why did not BTOR install cabs with vectoring capable line cards etc inside them from the start....

You need to ask yourself would you have been happy for YOUR cabinet not to have been done at all because the costs of everyone else's cabinet was going to be higher because of the more expensive vectoring-capable-cards.
So YOUR cabinet gets nothing as there is no more money for it.
There would have been screams of outrage on TBB, here, ISPreview and the rest on how we don't care about some tech in the future we just want better speeds 'now'.

I wonder if I should apply for Liv Garfield's job now that she is moving on......?
