Bill,

Customers look for what works where they want to use it.

ETSI CTR 3 compliant product (S/T interface) is accepted in the EU, duh, 
as well as Japan, Australia, New Zealand, Eastern Europe and lots of 
other places. Most use A-law.

The ANSI variant (U &/or S/T) only gets you the US and Canada. However, 
it's a large market.

You'll probably need both eventually.
