The system user is able to have one view into the system, at any given user access level, and may obtain needed information efficiently and effectively through electronic means.
When two or more capabilities are offered using the same system—each capable of operating interdependently with no significant loss of speed or performance—that system is said to be integrated. But what does that mean in practical telecommunications terms? It means that a network can offer different kinds of services over the same connections using the same protocols. For example, if voice signals are digitized and sent over a network using IP along with data and e-mail, then those services are "integrated."
This term means that the data from one module or system flows directly to another module or system without rekeying the data. Seamless integration means that the data flows automatically with no action required by the user.
