You need to have a splitter in the circuit. This is shown in the figure below:



Important: The voice/data splitter must be at the first entry point of the telephone line in the house.

The Modem C2110 which have the adapter, this adapter is not good. When the all lights of the Modem are blinking the fault from the adapter not from your modem. So you need to change the adapter otherwise the new modem is not working and shows same problem like before.
I dont know you have change your modem with the new adapter or not, if you have change your modem with the new adapter then I am sure that you have the AC Power fluctuation. This adapter cannot handel the Power fluctuation.

My Nokia Siemens C 2110 never gave a problem since it was installed in last Nov. Another user also had to replace the modem 2-3 times in a year.

interchanged , problem could arise.



Check any Firmware upgrade is required.
