Abstract:
Two connections are set up. The first one serves to transmit voice information and is controlled by a connection controller routed signaling H.225A, BICC*, H.225B. The second one serves to transmit image information and is controlled by a direct end point routed signaling H.245. Therefore, the services of the network PSTN can also be offered in full to the video telephony in an advantageous manner.
