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.
