Hi Mark,
I'll attempt to assist you on your question, though I'm not sure what exactly it is.
The 9000 as far as I could see doesn't support POTS fail-over, so if the WAN connection dies, no users will be able to make calls through it.
The 3102 does support automatic fail-over, so if the VoIP connection is not available it should use the POTS service. This can just be done by connecting a cable from the voice port to any phoneline available in the house. So your question: "As I only have one telephone line how do i connect theat line to the router AND the SPA3102." can be answered pretty easely. As the line is being split up for DSL signal and voice anyways, just connect the WAN port of the SPA3102 to the ADSL modem and the voice port to the voice side of the splitter.
Regards,
LucF
