Errr, I've yet to meet a rural ILEC that doesn't take the cost of the 
NID splitter vs inline splitters into account. ILECs will argue over a 
single $1/customer, and rightfully so. The cost of the FTTH NID adds 
considerably to the price per customer. In addition, it generates 
additional maintenance costs maintaining batteries. I've yet to hear an 
ILEC suggest that they not have batteries in the NID to support the 
voice in power outages. Batteries have shelf lives, and maintaining one 
per household is definitely more costly than maintaining the batteries 
to power the remotes.

Getting rid of costs, FTTH uses more power, and most of the people I've 
talked to said we can't feed it from the remotes even via copper mixed 
with the fiber. This creates issues when we need to provide service. 
Everyone always badmouth's the whole emergency phone thing, but we take 
it seriously in the rural areas where power outages are not uncommon, 
natural disasters are expected, and we are the ONLY utility that 
continues to function.
