Abstract
A modem which is separated into two circuit boards. One board contains the modem engine, while the second board contains the codec and the DAA components. The two boards are connected using only properly isolated digital signals so that the modem engine board does not require certification, only the codec/DAA board requiring certification. The codec/DAA board is contained in a housing to provide proper high voltage protection.
