I have reset the modem, unplugged the battery, disconnected and reconnected all the wires and the phone modem is still not online. What else can I do?
What lights are on the modem now?
As Kevin asked, how many lights are on the phone terminal? You should have solid POWER, DS, US and ONLINE lights. After that, the TEL1 light should be solid or flashing depending on if the phone is on or off hook (although a wiring issue can also show as off hook).
A great document for lights on the phone terminal can be found at Understanding your Digital Phone Terminal.
I've also sent you a private message as I'd like to follow up with you on this.
