Not capacity of those lines, but the commercial model involved. > > and second-last-mile (backhaul from DLE to the > > ISP's network via BT's ATM network) that's the problem.

The introduction of usage-based charging on IPStream enabled BTW's resellers to compete on price with the LLU operators and their resellers. The reseller is able to decide their own price points and usage caps in order to differentiate their offering, attract the bit of the market they're interested in, and hopefully still make a profit based on the mix of punters and their usage patterns. The older capacity-based charge simply left them making a fixed and downward-trending margin reselling a simple product. . If suddenly all their punters' usage patterns change for the worse, this screws their business model - hence the outcry about iPlayer. IPStream backhaul is a bit simpler - resellers buy it in bandwidth chunks called 'central pipes' - small ones (STM-1) or large ones (Gig-E). There's no metering as such, but obviously the aggregate bandwidth demands from a reseller's userbase, the more pipes they need to maintain a given level of contention.
