This chapter
is all about the variety of methods in which various signals travel for
communication purposes. It begins with convergence, the use of multiply terms
to refer to the same or similar technologies in common. For instant IP
Telephony the use of any network private or public to carry voice signals using
TCP/IP protocol. This technology is commonly known as VOIP. (Voice over IP) There
are many different clients and network designs with VOIP. One of the benefits of
using IP Telephony is it mobility. Analog VOIP needs to connect to an ATA
(analog telephone adapter) which digitizes the data in order for transmitting
purposes. It is much easier with Digital VOIP it typically connects to a PBX.
Videoconferencing
and streaming video opens another avenue of communication. It allows multiply participates
to communicate while viewing each other. This type of communicating depends
upon the exchange of information between the components of a network system to
establish connection.
The text provides some really good insight as to how all this different communication processes work. This synopsis only scratches the surface; the chapter goes into much more detail and covers many more topics.
