Interactive Distance Learning/Tele-Medicine

The IMACS’ integrated multi-service capabilities supports interactive distance learning applications where the central site and the major educational centers are connected through an ATM network and the remote sites are accessed via leased T1/E1 lines.

The video stream (TDM traffic) from the central site is adapted to ATM by the ATM server and multi-cast to the sites on the ATM network as shown in Figure 38. The ATM servers located at the Major University locations convert the video from ATM to TDM traffic and pass it on to remote sites over leased T1/E1. The IMACS’ ISDN PRI server is utilized in conjunction to connect the remote sites to the video-conferencing network over T1/E1 leased lines. The entire network is managed from a central network management system.

The same network structure is deployed effectively in a Tele Medicine application in which doctors from central medical centers can exchange patient information, X-rays etc. with remote hospitals and provide remote diagnosis.
