A modem adapter is provided to adapt a modem to operate with a telephone system. The modem adapter includes a conductor detector, a voltage generator, and a dial-tone generator. The conductor detector is configured to detect live conductors on a telephone jack. The voltage generator is configured to generate an on-hook line voltage comparable to that normally expected by the modem and to deliver the generated on-hook line voltage to the modem. The dial-tone generator is configured to generate and deliver to the modem a first dial tone different from the second dial tone delivered by a telephone system to which the modem is attempting communication. A method for adapting a modem to a telephone system is also provided.
