Abstract
A protocol processor functionality and a data pump functionality are included in a modem which is configurable in a number of modes of operation to effectuate both analog and digital data communications. When configured for analog data communications either over a telephone line of the wireline telephone network or using an analog capable mobile station of the cellular telephone network, data signals are routed through both the protocol processor functionality and the data pump functionality. The protocol processor is also connected to the mobile station to transmit and receive call supervision signals. When configured for digital data communications using a digital capable mobile station of the cellular telephone network, the data signals by-pass the data pump functionality and are transmitted by the protocol processor functionality along with the call supervision signals. In an alternative embodiment also configured for digital data communications using a digital capable mobile station, the data signals by-pass both the data pump functionality and the protocol processor functionality.
