There won't be any more busy tone from phone line, no more dropped connections, no more waiting for someone in the household to get off the phone. DSL offers users a choice of speeds ranging from 144 Kbps to 1.5Mbps. The DSL speed is 2.5x to 25x times faster than a standard 56Kbps dial-up modem. This digital service can be used to deliver bandwidth-intensive applications like streaming audio/video, online games, application programs, telephone calling, video conferencing and others high-bandwidth services within smaller time frame.FPRIVATE "TYPE=PICT;ALT=DSl - Network " DSL Modem ADSL (Asymmetric Digital Subscriber Line) - ADSL has data rate of .544 to 6.1 Mbps downstream; 16 to 640 Kbps upstream.

WAN video conferencing network design requirements for QoS Video conferencing is a real-time communications technology, like VoIP, which requires special treatment on the IP network. The wide area network (WAN) is a critical component of the infrastructure supporting video conferencing and must be properly configured in order to ensure high-quality video conferencing service delivery. The critical requirements of the WAN video conferencing network design are as follows: * To ensure that the WAN has adequate bandwidth. * To properly classify traffic and support that traffic in a dedicated class. * To support call admission control for bandwidth management. * To properly locate the multipoint conferencing unit or bridge. * To measure and monitor the WAN vendor. Let's take a look at each of these requirements in turn. # Determining adequate bandwidth for WAN video conferencing Video conferencing sessions can consume significant amounts of bandwidth. Video conferenc...
