A system for communicating telecommunication information between a telecommunication switch and customer premises equipment includes a gateway, a processing module, and a bypass switch. The gateway receives telecommunication information from the telecommunication switch. The gateway generates data packets for communicating the telecommunication information over a local loop circuit in a first mode of operation or generates a first analog signal for communicating the telecommunication information over the local loop circuit in a second mode of operation. The processing module receives the data packets from the local loop circuit and processes the data packets to generate a second analog telephone signal communicating the telecommunication information in the first mode of operation. The bypass switch selects the second analog signal for communication to a subscriber line in the first mode of operation and selects the first analog telephone signal for communication to the subscriber line in the second mode of operation.
