Dear Dwight, I would have to agree with VIC that the Canadian officials are a very responsive bunch. In my dealings with 100+ jurisdictions they always won the quick draw. Telecom New Zealand was a close second at times as was TAS(Singapore).
You do raise a point about the FCC registration. As HDSL has no FCC rules as of yet I don't believe that the modified interface can continue to be marked as a DD interface. This gets into areas of tariff issues and how phone companies look at FCC registration as indicating a regulated interface. If the product contained an FXO and a T1 interface and an HDSL than DD-T would be appropriate to cover registrered interfaces. Presumably the HDSL interface would be marked as HDSL. It is an interesting question and I would like to here other comments on this as well. You however do not need to formally deregister the existing T1 interface. Regards G. Rae Dulmage, B.
