List of BT Exchanges Set for a Spring 21CN WBC Broadband Upgrade

Interestingly BT appears to have informed UK ISPs that they plan to upgrade a large swathe of predominantly smaller telephone exchanges, many of which are in rural areas, from their older and slower 20th Century Network (20CN) based broadband and phone platform to the latest 21CN and Wholesale Broadband Connect (WBC) service between April and June 2015.

It’s been awhile since we saw one of these announcements, which is because BT effectively completed the main deployment of their new 21st Century Network during early 2014. As a result 92% of the United Kingdom (around 23 million premises) should now be within reach of the more modern network.

In practical consumer terms the legacy 20CN network, which is being replaced by 21CN, could only support older ‘up to’ 8Mbps ADSL lines. But to get the faster ‘up to’ 20-24Mbps ADSL2+ services your local telephone exchange needs to be based off 21CN and WBC. In addition, 21CN is often also used with other technologies, such as FTTC superfast broadband (note: this is usually deployed separately from the 21CN roll-out).

Now a new update from Internet provider AAISP, which we spotted this morning, indicates that BT are again pushing the “newIP based platform even deeper into their network. A closer look at the list reveals a number of areas, such as Bretton in West Yorkshire, which are also due for an FTTC upgrade in 2015 (note: Bretton itself was delayed slightly from late 2014). We suspect this will bring 21CN very close to 95% UK coverage (premises).

We suspect that the additional coverage might not have occurred without the Government’s Broadband Delivery UK programme, which is helping to push FTTC/P services and a 2Mbps Universal Service Commitment (USC) out to more isolated areas.

    But changing someone who can’t get 2 Meg from 20CN ADSL to 21CN ADSL2+ won’t improve their speed or get them 2 Meg. It might even make it worse. So it can’t be about minimum commitments or rates.

  2. Ben

    In addition, 21CN is also required for other technologies, such as FTTC superfast broadband

    Our local exchange has been upgraded for FTTC services under BDUK however 21CN/WBC isn’t available, do BT only upgrade the exchange for commercially funded exchanges rather than BDUK ones?

    • DTMark

      If I read this right in the past: the exchange does not need to have 21CN services for the cabinets on that exchange to have FTTC. In some cases fibre is run from another exchange.

    • X66yh

      21CN is not required at an exchange for the FTTC service IF the fibre to the cabs is fed from a neighbouring head end ‘master’ exchange…..as is sometimes done.

      I foresee a future topology of master exchanges and local satellite exchanges which in the very long term may be closed when voice is also handled by the local FTTC cabs…and everything controlled from mega regional exchanges.

  3. Jonathan Channon

    Blimey, my exchange is on that list. Hope they dont think this is good enough and I hope its just a baby step until we get FTTC

  4. adslmax

    Ironbridge, Shropshire is missing from the list!

    • Andy

      It’s not missing from that list – I just checked the BT Wholesale spreadsheet.

    • adslmax

      @ Andy what date is Ironbridge will be upgrading to 21CN as my mum friend live there waiting for ADSL2+

    • Andy

      No date, but FTTC/P looks to be covered under Telford Superfast’s coverage plans.

    • adslmax

      I wish Cuckoo Oak had FTTP as I can see from Sam Knows that Dawley, Shropshire had 21CN, FTTC and FTTP and FTTPoD.

    • Ignitionnet

      Dawley may have been planned for FTTP at some time but it doesn’t look like it has any. 28 cabinets of which 15 have FTTC.

    • Ignitionnet

      To save you asking Cuckoo Oak has 26 cabinets of which 16 have been enabled in the commercial programme it seems.

    • adslmax

      @ Ignitionnet does you mean Cuckoo Oak had a total of 26 cabinets but 16 cabinets are awaiting for installing?

  5. PeterM

    Pulborough is missing from this list. It has FTTC and some FTTP planned with the exchange only lines also being transfered to a fibre cabinet.
    Maybe these exchanges to be upgraded to 21CN have exchange only lines but BT don’t plan to upgrade them to FTTC.

  6. Dick

    Its entirely probable the upgrades would not have taken place without the BDUK programme. BT may have capilised on putting in extra capacity for 21CN whilst putting in Infrastructure for BDUK.

    It wouldn’t have been viable otherwise would it?

  7. Dick

    and its a cheaper way to get 24Mbps to some of the very close eo lines to the exchange

    • DTMark

      That’s probably not much more than a dozen premises per exchange.

    • TheFacts

      Can be many more.

    • GNewton

      @DTMark: “That’s probably not much more than a dozen premises per exchange.”
      In our town, there are thousands of exchange-only line, all using drop-wires from telegraph poles to the properties. Densely populated area.

  8. nga for all

    So why not skip 21c in exchanges which are not handover points and focus on 21c in and handover points serving Fttc?

    • Gadget

      I guess because the FTTC product is at premium over and above DSL so some folk may only want/need/be prepared to pay for a DSL service

    • nga for all

      @gadget if you have one upgrade and it is largely publicly funded you support that. perhaps fastman can be kind enough to comment, it probably the need to maintain standardisation.

    • No Clue

      “…perhaps fastman can be kind enough to comment, it probably the need to maintain standardisation.”

      LOL
