Onesie to the rescue in bringing superfast broadband to some areas
Friday 01 August 2014 10:34:31 by Andrew Ferguson

One of the problems in some parts of the UK is that the space on streets is limited, or even with the relaxation of planning rules the NIMBY effect means objections to a fibre twin cabinet being stood on a pavement.

At a briefing session in the St. Pauls BT headquarters which is in the City of London area where consumer priced superfast coverage can be difficult to find Joe Garner revealed plans to start deploying a combined VDSL2 and telephone cabinet which while larger than the old green street cabinets will take up less space than adding a new fibre twin. Most importantly this has implications for Exchange Only lines, since it may change the economics in both gap funded and commercial areas helping to get more of these EO lines upgraded to FTTC based services.

The new 'Onesie' has actually gone live in one location already, so it is not the figment of a press officer's mind. Some 119 premises in Andoversford will benefit from this cabinet and other cabinets will be installed in the coming months to improve speeds for others in the village. This cabinet was delivered via the Fastershire project (joint Herefordshire and Gloucestershire BDUK project) and the cabinet is the 100th to go live via the project.

The service delivered by this combined cabinet is identical to the standard cabinets i.e. FTTC in 40/2, 40/10 or 80/20 variants will be available. For those who are into their cabinet spotting we are chasing for a picture and actual dimensions.

Saturday 2nd August For those who like to play what is being delivered to their area, then @fastershire has a picture of the all-in-one cabinet on its twitter feed. The main differences are that it appears to be wider than the usual cabinets and from the front view ventilation slots are a lot less apparent than the standard fibre cabinets, we presume there are some around the side/rear, since the cabinet will be housing the mains powered VDSL2 hardware.

Andrew. Could a replacement cabinet such as this be the answer in Conservation Areas where Planning Permission is currently required?

it will have limitations as to how man connections it can supprt -- so good for a rutal villange where premises could is small to medium and where no PCP already exists -- it will be not use where a pcp already exists

Fttrn may be more useful. Will write that up later.

Combi cabs support up to 128 ports.
Apparently Shoreditch is the latest area mooted to test FTTRN

Andrew - just need to update your Not spot overlay on the map now because its outdated. Areas showing not spot and slow spot (2mbps or less) that have recently (in the two years) have been updated to FTTC and can now achieve speeds of 24mbps+.

For example:

The original architecture diagrams for FTTC had a combi cabinet, with the DSLAM sited above the PCP. After a lack of sightings over the last 4 years, you'd have assumed that BT had something of a bias against them.

I wonder why they suddenly got interested again?

All the easy ones done so the variations start to appear

Just what we need here in SW9 with a cluster of 75+ 2Km+ EO lines. I wonder whether BT will now reduce their quote to carry out the required network rearrangement?

Amberley on the Bury exchange in West Sussex is currently getting fibre. The exchange is 4.5km from Amberley and the newly positioned FTTC cabinet is 2.5km from Amberley. BT have laid fibre between Amberley and the cabinet. Amberley has 3 small cabinets in the village that have not been upgraded. Could BT be planning to use FTTRN with mini cabinets???
The Village is a conservation area with a wealthyresidentiall population of about 500.

@andrew
Looking forward to the write-up on FTTRN ;)

@chilting
Presumably that new FTTC cabinet serves more than just Amberley. There seems little point in leaving it there if *every* subscriber is at least 2.5km away.

The existing mini cabinets sound like SCPs, and could be a good candidates for FTTRN. SCP are rare, so they are unlikely to be a prerequisite in most places... The generic RN solution must be designed to work without an interconnect point.

@WWWombat
The cabinet just serves Amberley and Houghton [where the cabinet is located] plus a scattering of rural properties. There are only about 30-50 properties in Houghton.
We have a good number of SCP cabinets in this part of Sussex, they have a reputation of slowing our broadband speeds. Not sure if this is true?

Posted by andrew (Favicon staff member) over 2 years ago
SCP will only slow you down by virtue of the extra distance and extra joints they may introduce.
Posted by Unknown101 over 2 years ago
A SCP won't slow you down it's just basically a connection point above the ground than below. The use of SCP is mainly on long lines (I say mainly because around where I live they are on some short lines too), so the fact they use them on long lines and that seems to be your issue then that's why your broadband is slow. I have seen smaller ECI DSLAM's on SCP's which I think is a good idea, especially if the SCP is much closer than the PCP.

There are no SCP cabinets with an FTTC cab of their own. An SCP would be converted to a PCP and the original PCP bypassed before an FTTC cabinet is provided.
Posted by chilting over 2 years ago
Presumably it would be fairly simple and inexpensive to run fibre to a SCP through existing ducting and then installing FTTRN in the SCP, fed from the FTTC. If some of the line runs above ground, is this a big problem?

ribble - "There are no SCP cabinets with an FTTC cab of their own. An SCP would be converted to a PCP and the original PCP bypassed before an FTTC cabinet is provided."

Could you explain that another way?I am having trouble understanding.
Posted by chilting over 2 years ago
@mikejp
I think I am right in saying that the SCP runs directly from the PCP and that they can be connected together with copper or fibre. All customers, including those on ADSL, would benefit from a increase in speed if fibre is installed between the PCP and SCP but only those on FTTC would get the full benefit right back to the exchange.

"All customers, including those on ADSL, would benefit from a increase in speed if fibre is installed between the PCP and SCP" - sadly my understanding is not, just as non-FTTC (ADSL users) do not benfit from the PCP being fibred.
Posted by chilting over 2 years ago
@mikejp
I guess that depends if the fibre is a substitute for the copper from the PCP to the SCP or an addition to it [ie. just for the upgraded FTTC lines]. My technical knowledge does not stretch that far!
Posted by mikejp over 2 years ago
It cannot be a 'substitute' or the ADSL folk will be 'without'. My knowledge of FTTRN is very limited but I assume fibre is added to the ducting from an aggregation point, and the 'cheapest' will be along the existing PCP-SCP ducting rather than a new dig.
