the priority is in the case of 20CN BT services the Office or Premium vs Home service, the former having a higher upload speed (832 ns 448) and a higher priority for traffic at the ATM level which gives it double the minimum acceptable speed.
In 21CN / WBC terms the priority becomes "Elevated Best Efforts". The upload speeds are the same but the higher priority remains.

excluding products with '8000' in the name :-
"WBC
Elevated is used to provide Zen Office and Zen Office Max"
"WBC Standard is used to provide Zen Pro, Active and Lite"
"IPStream Max is used to provide Zen 8000 Pro, Active and Lite"
"IPStream Max
Premium is used to provide Zen Office 8000 and Zen Office 8000 Max"
When WBC arrives it depends on the ISP's policy whether you are migrated over or not. The two services continue to be available in parallel. Router requirements are the same, WBC may benefit from ADSL2 / 2+ capability.
