A 64 KB communication channel could simultaneously carry four conversations compressed at 8 KB and 32 KB of data traffic . The multiplexer chosen for the IVDN allocates communication line space dynamically in this way, and also take advantage of idle time in conversations to transmit data . The future of this kind of networking is to mix video in with voice and data. However, video requires more bandwidth than the IVDN can provide at this time. Much of the necessary infrastructure will be in place should Centers decide to invest in the required bandwidth in the future .
