Abstract

A method of transmitting data bits over a modem connection. The method includes receiving a first stream of data bits, by a first modem, performing a first set of one or more communication tasks on the first stream of bits, by the first modem, so as to generate a second stream of bits, modulating the second stream of bits, by the first modem, so as to form a modulated signal, transmitting the modulated signal from the first modem to a second modem, demodulating the modulated signal by the second modem, so as to form a third stream of bits, performing on the third stream of bits, a second set of zero or more communication tasks, including a different number of tasks than the first set of tasks, so as to form a fourth stream of bits, and transmitting the fourth stream of bits to a communication unit over a packet based network.
