  1. 1. How Traffic Moves over the Internet <ul><li>Multi Protocol </li></ul><ul><li>BRI </li></ul><ul><li>What is TA? </li></ul><ul><li>B channel and D channel </li></ul><ul><li>Kentaro Yamamoto </li></ul><ul><li>Kazuki Funada </li></ul><ul><li>Takahiro Watanabe </li></ul>
  2. 2. Multi Protocol <ul><li>ISP is connect internet server by IX. </li></ul><ul><li>And user access point of ISP for using internet. </li></ul><ul><li>We can get more high quality by using new device. </li></ul>
  3. 3. BRI <ul><li>Code converters, convert eight-bit voice sample code from either the voice terminals or the central office switch to four-bit sample code in the interface. </li></ul>
  4. 4. What is TA? <ul><li>Generally the TA is connected to the ISDN line and points at the communications equipment which interface convert to connect the information appliances such as the analog telephone or computer. </li></ul>
  5. 5. B channel and D channel The one of the kinds of a logic line constituting the connection specifications of the telecommunication line in an ISDN standard together. B channel is used as data transmission channel for communication, and D channel is used for it to offer the signal which I communicate and control and an addition function of B channel. In the ISDN standard, one physics line consists of plural B channel and one D channel.
