Systems and methods are provided wherein an incoming plain old telephone systems (PSTN) signal is input into a network conversion interface. The network conversion interface first determines the data type of the incoming signal. Next, the network conversion interface creates a routing sequence of the incoming signal based on the determined data type. Finally, the network conversion interface converts the incoming signal into an 802.X format and sends the signal to an appropriate IP device based on the determined signal type. Should the network conversion interface lose electrical power, a drop contactor routes the incoming signal directly to an analog device without creating a routing sequence or performing an 802.X conversion.
