follows the same path, this is the foundation of the PSTN. The basic principle in which the VoIP works is known as ‘packet switching’. Instead of sending a continuous stream of bytes, in VoIP, the bytes are sent only in packets. These bytes are routed through a chaotic network, instead of a dedicated line. The entire process is known as packet switching. In packet switching, the connection is opened for only a brief instant, just the time required to send a small ‘packet’ of data, from one system

X.25 Protocol A history of the X.25 Protocol Tim Elliott Morrisville State College Abstract X.25 is a Wide Area Network standard suite of protocols for packet switching developed by the International Telecommunication Union-Telecommunication Standardization Sector in the early 1970’s. It was designed to support traditional data networking over telephone wiring. Though widely used in the 1980’s, it has been largely replaced by newer IP standards such as frame relay. The purpose of this protocol

In the pre 1995 Lucent’s supply chain, most of the Asian production was manufactured in Oklahoma City. The focus was on USA customers and business from Asia was not significant, therefore there were no manufacturing
