The present application provides a variety of exemplary embodiments, such as modem systems, modem devices, modem connectors, host connectors, communication systems and communication cards. For example, there is provided a modem device for use to enable a host to communicate over a communication line, wherein the host has a connector. The modem device comprises a line side circuitry (215) capable of interfacing with the communication line (205), and digital isolation barrier DIB (220) coupled to the line side circuitry (215), the digital isolation barrier capable of being connected to a modem connector (230) for connection to the host computer, wherein the digital isolation barrier is capable of isolating the modem connector from the line side circuitry. Moreover, the line side circuitry may include a line side DIB interface for communication with the digital isolation barrier. Also, the modem connector may be connected to the digital isolation barrier via one or more lines.
