Abstract: The multiple modem apparatus has a number of analog front ends that feed analog signals to and receive analog signals from a modem controller circuit. The modem controller circuit has a codec function for sampling, quantizing, and digitizing the received analog signals. The codec additionally creates an analog signal from digitized signals received from the other side of the modem apparatus. A digital signal processing function provides digital processing of digital signals. An Ethernet device converts digital signals from the modem controller circuit to the Ethernet format and Ethernet signals going to the modem controller circuit are converted from the Ethernet format to digital data. A multiple modem apparatus controller controls the operation of the apparatus while providing synchronization of the multiple analog front ends and routing of data.
