A system for providing lifeline telecommunication service includes a telecommunication interface, a data packet service module, an analog signal service module, a power generator, and a switch. The telecommunication interface receives telecommunication information from a telecommunication switch. The data packet service module receives the telecommunication information from the telecommunication interface and generates data packets for communicating the telecommunication information over a local loop circuit in a first mode of operation. The analog signal service module receives the telecommunication information from the telecommunication interface and generates an analog signal for communicating the telecommunication information over the local loop circuit in a second mode of operation. The power generator generates a first voltage. The switch selects the first voltage for communication to the local loop circuit in the first mode of operation and selects the analog signal for communication to the local loop circuit in the second mode of operation.
