What tariff rate? DSL is unregulated and de-tariffed.
It is also subsidized by voice services, since it uses the same copper
Billing is miniscule (less than $1) because you already get a bill.
Their IP and ATM combined cost is less than $2 per subscriber.
The real overhead is tech support and the DSG (DSL Support Group).
