Doesn't sound good. Does it do that with nothing but the power supply connected?
You might try holding the reset button depressed for an extended period of time. It's accessed through a hole on the bottom side of the unit.
After that, does a telephone connected to the PHONE Port get dialtone?
If so, does connecting the Ethernet port to your router and dialing ***1 report a valid IP address?
If so, does dialing **9 222 222 222 connect you to the echo test?
