4. TYPES OF TELECOMMUNICATION NETWORKS
There are many different network structures to
efficiently route messages, for example:
• Wide area networks (WAN)
• Metropolitan area networks (MAN)
• Local area networks (LAN)
• Internet area networks (IAN)
• Campus area networks (CAN)
• Virtual private networks (VPN)
• Enterprise private networks (EPN)
5. ENTERPRISE PRIVATE NETWORK (EPN)

7. HISTORY
• In the U.S., private networks were started in the early 1970s by
AT&T. The networks were mainly operated over
telecommunications networks. During 1990s as Internet
technology evolved, a new type of network called virtual private
networks originated. This type of network was built over public
infrastructure, and the data was encrypted to protect it from
eavesdroppers.
• Nowadays, networks built by companies are still called enterprise
private networks when privacy is maintained through security
procedures and tunneling protocols like Layer 2 Tunneling
Protocol.
10. USEFUL INFORMATION
Many business applications of telecommunication involve the use of the internet,
extranet, and other networks to form interenterprise networks.
Such networks link a company’s headquarters and other location to the networks of
its customer, suppliers and other organization.
For example:
You think of a customer account inquiry system that provides intranet access by
employees and extranet access by customer.so it is an other example of
interenterprise network.
So is the use of Electronic data interchange.(EDI) systems that link the
computers of a company with those of its suppliers and customers for the electronic
exchange of business documents.
