Abstract
A communications and IP network gateway interface unit is provided for use with educational systems in a classroom environment. The gateway interface is configured to communicate with an IP network, and includes a digital signal processing unit storing programs for processing encoded data signals received from the IP network to produce an enhanced audio output. The audio output can be coupled to a telephone interface and connection for telephony communication configured to produce a voice signal portion of the audio output. The gateway interface further includes ports for sending a program audio signal such as music to a set of speakers, and for receiving audio from a microphone. Interface ports for synchronizing a clock are also included, as well as call switches, message display boards, audio-visual displays, in-class computer terminals, and other devices used to enhance and secure the educational environment.
