Figure 37—Migrating Legacy Networks to ATM
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.
