BT Infinity Cabinet Install

[MadGamer]

They install both a router and separate modem. Your master socket gets replaced by an Infinity NTE5 Master Socket, which has a filter built into it. Speed wise depends on line length, Line quality, and distance from the street cabinet

ok, thanks.

Best infinity line speed ive seen is about 39mbps, worst about 8mbps. All depends on your line quality.

Where I live we have a revised date of 31/12/11 for infinity and yesterday about a mile away notice that finally the plinth and ducts have been installed (as first photograph) for the VDSL cabinet. The word 'dslam' had been sprayed on the footpath since June!

What I would like to know is that does every existing street cabinet require a VDSL cabinet or can one VDSL cabinet serve several existing street cabinets? The reason I ask is further down the road is 'our cabinet' and there is no sign of a new cabinet popping up around it. Exploratory work has been done because other services have been identified by markings on the footpath.

Also do BT bring the fibre from the exchange separetely to each cabinet or run a multifibre cable to an area and then off to each VDSL cabinet (our exchange is nearly 3 miles away)!

Thanks,

Tony

These Infinity cabinets are only cross connected to primary splice cabinets. Some street cabinets on BT's network can act as an extension to a primary cabinet so wont have the need for a VDSL cabinet. BT are generally only fitting these new cabinets in areas where there is a high penetration of customers, not every cabinets in a connected exchange area will receive service.

I have family living next to a VDSL cabinet but also very close to the exchange. Their phone line is directly connected to the exchange and not to the street cabinet so they cannot get infinity... some great Telecomms planning that!

Each cabinet has a mutipair blown fibre trunk connected back to the headend and are fed by a single fibre. The blown fibre duct allows for more fibre to connected in future as the technology changes and demand increases.

Thanks Weesteev,

Obviously I was being impatient as yesterday when I went out they have now started the groundwork for a VDSL cabinet next to 'our street cabinet', and the other site now has a VDSL cabinet in-place.

Thanks for the information re the configuration of the cabinets/ exchange etc. Am I right to assume the biggest task will be getting the fibre from the exchange to 'our' cabinet? What is the normal timeframe for then integrating this within BT's network once all the equipment is in place and live?

At the moment BT's website states 31st December 2011 as available is this likely to slip or be brought forward?

Cheers, and thanks for the reply

Now, now, when the network was built it was all exchange based so as few PCPs as possible would have been the ideal

Reading through this PDF BT are using two different cabinets, there's a 288 line variant and a 128 line variant so they are using the 128 line cabinets in lower density areas.

BT are doing infill of cabinets in some exchanges, using a combination of the 288 and 128 line cabinets, there are 'rumours' that BT will deploy FTTP to exchange only lines.

I'll dive in here. Getting the fibre to the cabinet is usually easy, the power is a bit trickier but shouldn't be a problem. Chances are it'll be a bit before 31st December as Openreach won't have people working on civils around Christmas so much.

The date given is a timeline for when a certain percentage of cabinets will be ready by not an absolute date where they'll switch them all on on the 31st.

You should hear your cabinet start to hum when power is plugged in, then once the exchange is ready you're good to go - keep an eye on things and maybe give BT or whoever you want to take the service from a call after the cabinet has been powered for a couple of weeks.

Thanks Ignitionnet

That filled in more gaps in my knowledge and thanks for the tips re listening out etc. By the way the pdf you refered to is that in the public domain?

Thanks

Spot on Igni, when it comes to power, Telcos are at the mercy of the local power network and some of them have unreal timescales for processing new connections. Once the cabinets are in place you will find a few weeks/months later that the power utility will come along and dig up again to provide a power connection to the cab then BT will come back and activate the cabinet.

As for cabinets, 228 line shell is in my first pictures and the 128 line is in the second pictures.
