However it will lead to problems in the future, as RevK made clear in his blog post a couple of weeks ago - the beauty of the Ethernet termination is the fault demarcation of the IP service is clear.
The same could be said for ADSL and at very least the option for the engineer install is still there.
Cost-benefit analysis on the part of the ISPs.
Interesting that the Reverend says that the Openreach modem is the demarcation point of the IP service, the IP service rides over the DSL and PPPoE segments. It becomes pure IP at the ISP, prior to that if using BT Wholesale it's riding over PPPoE over IP, PPPoE, no IP network as it's delivered to Wholesale via a layer 2 network, and VDSL.
It's the demarcation for VDSL but that's about all I'd have thought. There's another demarcation at the L2 switch between Openreach and the CP which is the Ethernet demarcation.
Bit confused by the Rev's terminology there but I'm sure he knows more than I do about this stuff.
