Using Telephone and Cable Networks for Data Transmission

TELEPHONE NETWORK
Telephone networks use circuit switching. The telephone network had its beginnings in the late 1800s. The entire network, which is referred to as the plain old telephone system (POTS), was originally an analog system using analog signals to transmit voice.

TRANSMISSION MEDIA , ANALOG VS DIGITAL DATA TRANSMISSION



INTRODUCTION
The transmission medium is the physical path between the transmitter and receiver in a data transmission system.
Transmission media is divided into two types: Guided(wired) or Unguided(Wireless).
Wired Media is the most common and is further divided into three different types of cabling: Coaxial, Twisted Pair, and Fiber Optic Cables
Wireless media, which is, in a sense, no media ....etc

It is a protocol that supports the delivery of POTS over the loop emulation service which helps to convey analog supervisory signaling states is commonly used by IWFs (interworking functions to support CCS ( Common Chanel Signalling). To avoid the signaling analog line states this protocol uses the simiar message set as the V5-PSTN (ETSI EN 300/324-1) thus covering the risk due to the variations seen in individual national implementation of analog POTS. ....etc

Abstract

This project Secured Data Transmission through Network handles hiding a secret message with in an image in such a way that others cannot discern the presence or contents of the hidden message. A message might be hidden with in an image by changing Least Significant Bit to be the message bits. Then the image can be transmitted through Network.LSB based Steganography is perhaps the most simple and straight forward approach. In this project we embed the message in to the least significant bit planes of the image. Since this wi ....etc
