History of Internet
The INTERNET was born in 1969, when a paranoid American military had dreams about the primary communication centers being bombed out by Russians. To prevent suck occurrence, the ARPA (Advanced Research Projects Agency) set up four communication hosts, linking them in such a fashion which would ensure that even if one got bombed out. Communication would route around the affected area and stay alive. This network called ARPA net quickly grew. This primary service on ARPA net was electronic mail. It was the first time that emails actually came into use. In very short time, students began linking their own campus networks into ARPA net, using a well-defined protocol TCP-IP. This joining of networks was also called inter-networking, and soon the entire setup was called INTERENT. In 1973, ARPA net allowed international bodies to the net, and after that there was no stopping.
PSTN
The public switched telephone network (PSTN) is the network of the world's public circuit switched telephone networks. It consists of telephone lines, fiber optic cables, microwave transmission links, cellular networks, communications satellites, and undersea telephone cables, all inter-connected by switching centers, thus allowing any telephone in the world to communicate with any other. (Wikipedia)
PSTN is needed to meet the requirements of the individuals, organizations and offices to transmit telephone messages all over the country. It should provide access to the international network and also interconnection with the private networks and exchanges having access to the PSTN, complying with the requirements of the present document. When the corresponding terminal equipment is used, the PSTN should support the data transmission, facsimile transmission, E-mail and other messages with the cross point switching.
