UK ISP Andrews & Arnold (AAISP) has written an interesting BLOG POST about the problems they're having with BT and upgrading their platforms to the operators latest 21st Century Network (21CN / ADSL+) network. It makes for a good read and helps to show the difficulties that ISPs often have to deal with behind the scenes.


It should be noted that WBMC refers to the Managed version of BT's up to 24Mbps ADSL2+ related Wholesale Broadband Connect (WBC) products. The managed service has suffered some delays, thus slowing the ability of other BT based UK ISPs to launch their own 24Mbps products.

Providers can of course adopt the vanilla WBC, although it lacks some of the managed products benefits, such as being able to work with older IPStream Central Pipes (i.e. the old broadband platform). WBMC could make it easier to migrate existing customers over to the faster products.
