I think perhaps we have an acronym collision here. I read Scott's
comment to mean "Customer Premises Equipment", since that was the only
parsing that didn't introduce a conflict.
However, I read Tony's reply as "Customer Provided Equipment", since
that's my usual parsing of that acronym.
In this case, it makes quite a difference. Clarification?
Better: why not, Tony?
