More on the wBC ADSL2+ trial
We don't know if BT Wholesale has as yet got the 250 people for its ADSL2+ Wholesale Broadband Connect (wBC) trial, but some more information about the service is included in a press release from Entanet.
It should be pointed out that even if you apply and a service provider takes your details for the trial, BT Wholesale may reject the application as they will be looking for a spread of lines across the ten exchanges.
"As well as Internet access, customers participating in the trial will also be able to make voice calls over their broadband line, with a maximum of £50 per quarter call allowance. Once the trial ends in mid-January 2008, customers that have an existing connection with Entanet will have the option of continuing to use the WBC service or reverting back to their former service."Carol Davies (Business Development Manager), Entanet
Subsidised voice calls will make this trial more attractive to people, even though the trial is fairly short. Of interest to lots of ADSL users, will be the news that while the upstream will be initially rate adaptive up to 448Kbps, higher upstream rates exploiting Annex M may offer speeds of 2Mbps at some point during the trial.
The wBC service is due to be available in two flavours once launched and service providers will have the choice to mix and match based on their own economics. The managed version wMBC is more akin to the existing IPStream based services with data from the regions being delivered to one location. The pure wBC product provides the data for a region at an aggregation point where the provider can hand it off to their own network. So to cover the complete UK, a provider using wBC would need to link to 20 aggregation points. The pure wBC product is likely to be cheaper providing the location for a region is close to their existing backbone (or someone else's they rent capacity on). This means that the most likely architecture will be a mixture of the two options apart from a few of the very large providers.
