da). One interesting feature of these systems is their on-line application. This utilization offers not only long-distance learning but also the integration of data services and voice trunking. Software has been developed specifically for the purpose of networking classrooms to facilitate them to simultaneously pull files from the Internet and to enhance the learning experience (Shenoda). On-line applications can be supported over existing ATM networks. Shenoda observes: “H.320 networks can be supported on ATM networks today, much like voice, using CES between terminals and MCUs. For example, ADC Kentrox AAC-3 equipment is used to support a distance-learning application among 40 schools, though not all schools are online yet. It offers interactive video teaching plus integration of data services and voice trunking on the same ATM network. Special software has been developed in the network control system to take care of the scheduling. At preprogrammed hours, the network control system reconfigures the ATM VCCs to interconnect the appropriate classrooms with each other, and set up the MCU to perform the proper redistribution of audiovisual signals. In the meantime, any class can simultaneously pull files from servers across the Internet via the gateway router. In this manner, information may be pulled from any Web server to the multiple classrooms participating in the session (Shenoda)”. While training and documentation for on-line systems is critical for its efficient use, database considerations are not significantly different from typical requirements nor are access and security requirements.Business ApplicationsAs businesses move from “Main Street” to a global presence, they experience more and more needs in terms of technology. Often times the various fractions of a business are spread across wide geographic areas and coordination between the various offices is easily disjointed. Technological advanc...
