Absoutely!! I was only trying to clear up my misconception about the diagrams which did not show the GSM core network that the 1X BTS was sitting on. I thought the 1X BTS was sitting on a ANSI core network in the diagrams. I thought the GSM/GPRS BTS in the diagram was sitting on a GSM MAP core networks. I didn't realize both the 1X BTS and GSM/GPRS BTS were sitting on GSM MAP core networks. That's all.

In addition to the IS-833 overlay, they will surely want to consider a network to network interface (NNI) or bridge between the existing ANSI-41 based core CDMA network(s) and the existing GSM MAP core networks to enhance interoperability beyond some the interoperability afforded by dual-mode 1xRTT/GSM GPRS handsets, and to allow sharing of protocols and databases of some of the core network peripherals. Isn't this what the SIM/RUIM is designed to do in the dual mode handsets?
