Re: [EFM] EFM Requirements

Thank you, Frank,

        despite I dig deeply into my dictionary to understand word "howdy" (as a
non English-speaking person).

        Anyway, seems I understand your point - fiber plus a copper mile
requires too big investment and may not justify the business case. Could be. But
what is the alternative? Wireless or relay connection? Cable connection?
Dedicated copper cable binders? My point is that when we talk about "reach
improvement" in a modern DSL that means 5-10 %. It is probably impossible to
make ADSL working over 15 kft with any decent bit rate, as well as it is not
possible to make VDSL working over 5 kft (I am talking 26AWG). So, we probably
need to take a look on business cases which doesn't require to disturb Mr.
