Elements of converged networks

As explained earlier, the converged network integrates data, voice, and video into a single network. This is achieved thanks to the technologically advanced equipment and the TCP/IP protocol. Thus, it can be said that the elements of converged networks are a convergent device and a converged service. An example of a convergent device is the multiplexer (as in Figure 1.26) that, at its input, merges multiple communication signals into a single signal at its output. For the converged service, it can be said that it is a service that provides voice, data, and video signals in a single network, thus providing services for all modes of communication:
