Abstract
Method and apparatus are disclosed to allow non-wireless transmission or reception of data from one device to at least another device. More particularly, in one embodiment, a jack of a first device is configured to receive incoming analog signals encoded with digital data from the second device and to transmit outgoing analog signals encoded with digital data to the second device. The first device may also comprise a first conversion unit configured to encode digital data into the outgoing analog signals and a second conversion unit configured to recover digital data from the incoming analog signals.
