    Along the path from the source to destination, there are differences between the modes of switching information from one line to another for different nodes. Since the major multiSwitch bearer network is based on the packet switching network, we will primarily describe the packet switching mode below.

  • Page 8: Packet Switching

    – user manual 1.2 Packet switching In the packet switching network, data are transmitted in short packets which have a maximum size limit. If a larger packet is to be sent from a source site, this packet will be split into a series of shorter packets.

  • Page 9: Ip Voice Coding And Compression Modes

    – user manual In this case, each session packet does not monopolize a circuit. Instead, it is sent only when the circuit is idle. In this way, multiple sessions can share one channel asynchronously. Thus, the circuit utilization ratio is considerably increased.

    & maintenance costs on a high level, and furthermore, a network cannot provide complicated convergence services, although the network convergence has been an inevitable trend. Hierarchical models are adopted for the MultiSwitch - based Next Generation Network (NGN). The entire network can be divided into five levels: Application Level, Call Management Level, Infrastructure Level, Interface Equipment Level and Customer Premises Level, as shown in Figure 1.
