Abstract

A multimedia interface circuit is used to connect multimedia signal sources such as a telephone to a network. The multimedia interface circuit has a telephone communication interface circuit for receiving the telephone signal from the telephone. A signal conditioner receives the signal from the telephone communication interface circuit and conditions it for use on the network. A phone environment simulator cooperates with the signal conditioner to add an artificially simulated phone environment to the signal. The signal is then sent by a network communication circuit to the network. Personal computers and video sources may also be connected by the multimedia interface circuit to the network.
