A system for providing lifeline telecommunication service includes a
gateway, an analog signal service module, and an integrated access
device. The gateway receives telecommunication information from a
telecommunication switch and generates data packets for communicating the
telecommunication information. The analog signal service module is
remotely coupled to the gateway. The analog signal service module may
receive the data packets from the gateway and generate a first analog
telephone signal for communicating the telecommunication information over
a local loop circuit. Coupled to the local loop circuit, the integrated
access device may receive the first analog telephone signal from the
analog signal service module and communicate the first analog telephone
signal to a subscriber line in a first mode of operation. The integrated
access device also may receive the data packets from the gateway, process
the data packets to generate a second analog telephone signal
communicating the telecommunication information, and communicate the
second analog telephone signal to the subscriber line in a second mode of
operation.
