CHAPTER I/INFORMATIONTECHNOLOGY 5
(1) An IT system is composed of a communication network, terminals such
as workstations and graphics workstations, human-machine interface
modules, and intelligent processing modules.
(2) Users can access services through the terminals.
(3) The server has intelligent processing facilities, such as media
conversion translation, or natural language processing facilities.
(4) The human-machine interface modules have natural language
processing, speech processing, image processing, and gesture
recognition facilities and provide human-friendly services to clients,

1.2 INTELLIGENT NETWORK CONCEPT

The next-generation communication network, called the intelligent network (IN)
has been studied in many countries, especially the advanced countries (Figure 1.2).
The functions needed for the IN are as follows.
(1) The network acts as a platform for information services. In concrete
terms, connectivity between an information provider and a client must be fully
available in the communication network. To achieve this, the network provides
transmission paths that are transparent not only to information providers but also
to clients with respect to the numbering plan, the fee policy, and the like.
(2) The network is independent of services and equipment. Many kinds of
terminals and services will be installed in the network, so it should accommodate
all kinds of services and equipment.
