BT Wholesale reach 5 million broadband users on 21C network
Wednesday 25 August 2010 14:45:16 by John Hunt

BT Wholesale have announced today that they are now running over 5 million broadband users on their Wholesale Broadband Managed Connect (WBMC) over IPStream Connect service. IPStream Connect is the migration path for wholesale customers who have legacy 20CN connections to move these on to the new 21st Century Network (21CN). Making the move allows broadband users to be delivered over a unified link along with the next-generation services such as up to 24meg from ADSL2+ and up to 40meg from fibre-to-the-cabinet (FTTC).

The 5 million milestone comes after 230,000 customers were moved last night at the Ilford exchange which follows further transfers that have been carried out in August at Faraday and Kingston exchanges. Service providers can gain cost savings by moving legacy customers over on to WBMC with IPStream Connect as it allows them to decommission the BT Central pipes which are used for providing the backhaul for older IPStream services which have been in use since broadband became available in the UK back in 2000. BT Wholesale now has over 50 service providers using WBMC and IPStream connect to backhaul their broadband customers.

Well if you go off the large number of 21CN service status messages I get from Plus Net on a weekly basis, I really don't want to move onto 21CN as it seems constantly plagued by problems and maintenance issues.

Also isn't 21CN already having capacity issues?

Posted by Legolash2o over 6 years ago
Yeah. 21CN seemed obsolete before it even started, but at least it will allow BT to install FTTC/FTTP as 21CN is needed to be done first.

I keep getting spam email from plusnet about their services and 21CN, no idea why.

Obsolete?

Quick check of the link, oh god not this World Cup thing again, it has been done to death...
Posted by Legolash2o over 6 years ago
I wasn't even thinking about the World Cup, i was thinking that 21CN should of been done along time ago, so maybe obsolete is the wrong word.

^^ Too little, too late... Probably better ;)

I don't think its too little, but maybe a bit late yeah

How are BT doing with the massively-performance-improving miracle called 21CN voice?

From over a year ago: "We still plan to proceed with the planned migration to 21CN voice services across the country from 2010, but it will be at a slower pace and smaller scale than previously envisaged." http://www.openreach.co.uk/orpg/news/21cn/briefing_21cn00909.do

This was in the "21CN Strategic Briefing" series, which hasn't been updated since January.

Maybe 21CN isn't so strategic any more?

overtaken by FTTC
Posted by CARPETBURN over 6 years ago
^^^ Hmm so that would be 5 million with as good as abandoned 21CN then?

cb - where does it say 21CN for broadband is abandoned?
Posted by Legolash2o over 6 years ago
21CN is needed for FTTC and FTTP.
Posted by Legolash2o over 6 years ago
Although, it's a shame because they upgrade the exchange with ADSL2 cards and then within 2 years alot of them are being replaced with FTTC. What a waste of money, but should stop ADSL2+ and continue on the list as before but with FTTC, in the LONG run they would save millions.

I said "as good as abandoned". Maybe i misunderstood what you meant by "overtaken by FTTC", care to explain?
Posted by CaptainHulaHoop over 6 years ago
21CN is used as the backhaul for BTWS on FTTC/FTTP, ADSL2 is a byproduct of it really.
and from what i understand it removes the old style 50:1 contention at a local level and moves it back to central nodes, could be wrong on that though
Posted by GMAN99 over 6 years ago
Lego nothing will be replaced they are putting in MSAN's not ADSL2 DSLAM's like LLU providers
Posted by Legolash2o over 6 years ago
Ah didn't know ADSL2 was a "byproduct", i apologize.

Yeah 21CN has "contention control". Don't have a clue how that works to be honest.
Posted by GMAN99 over 6 years ago
Well its not a by product its just a line card in the MSAN chassis, so for areas where FTTC is a while off they can populate with ADSL2 cards, when FTTC comes along replace it with VDSL ones, I can't imagine they'll lose much money on the ADSL2+ ones they'll just go elsewhere or be resold, I dunno... but its not like putting in and taking out DSLAM's which would as you say be a real waste of time/money
Posted by Legolash2o over 6 years ago
But arn't they moving DSLAMs into the FTTC cabinets anyway?

Does anyone know what hardware is in the FTTC cabinet?
Posted by GMAN99 over 6 years ago
A VDSL DSLAM yep
Posted by Legolash2o over 6 years ago
i can't wait for FTTC, do you think they will offer a service to install a fibre cable to your home from the FTTC cab? If im willing to pay for it and the price is right or would FTTH/FTTC mix require a new cab??
Posted by herdwick over 6 years ago
FTTH probably doesn't require a cab, as BT would use GPON possibly from many miles away. Google will help with GPON for example http://it.tmcnet.com/topics/it/articles/65274-migrating-from-copper-fiber-vdsl2-gpon.htm

splitters can live in the ground and are passive so no cab or power strictly needed.
Posted by GMAN99 over 6 years ago
I would imagine that is how they will do it in the future yes, some sort of fibre concentrator that will take in many fibres from the premises and then have a 2 or 3 fibres back to the exchange, just my thoughts of course I don't know what is planned but that is what I would expect.
Posted by GMAN99 over 6 years ago
Yeah or something like that herdwick :) Either way.. I'd say its a while off
Posted by Legolash2o over 6 years ago
Thanks Herdwick, that was a very good read :D

BT are describing 21CN broadband as being a 'mixed economy' with FTTP available to around 25% of premises. Initially this will be to exchange direct fed lines (i.e. lines from an exchange not fed via a street cabinet). Cab fed lines should eventually get VDSL2 (FTTC) with ADSL2+ being available until FTTC is rolled out to the local cabinet. Some cabs will not get FTTC as it will not be financially viable and will likely remain ADSL2+ for some considerable time.

None of the above happens if 21CN WBC isn't enabled at the local exchange as the 21CN backhaul needs to be in place.
