With Classroom Peripherals � classrooms are configurable with any combination of devices, some of which are loudspeakers, call switches, telephones, and clocks.

Media Retrieval � This system permits access and control of media sources. For instance, a classroom instructor can operate a media device (i.e., DVD player or VCR) located at a central location using a handheld remote or the classroom telephone.
