     I'm not real sure what LV's tryin to do, but I think this whole 
deal is ISP/phone line specific. In my case when I got DSL I kept a 
dialup Earthlink account for a while.  The DSL line uses micro 
filters to split out analog voice signal from the digital line. So 
I figured, no problem, I can connect both my ATU-R (dsl modem) and 
my dialup modem. DSL line to the ATU-R, filter out an analog signal 
to the dialup modem.

    No go. With both connected, neither would work even tho the 
other was not in use. Only physically disconnecting one or the 
other would allow me to to switch between digital DSL and analog 
dialup. OTOH, I've got the DSL line into the ATU-R, and using a 
micro filter to also connect my phone, that works. Since LV's cable 
is a digital line, and dialup needs analog, I reckon he's in a 
similar situation as mine.
