CHAPTER 28

  1. Information about Frame Relay commercial products can be obtained from http://www.lucent.com and http://www.cisco.com.

  2. You can study the FRAD interfaces provided by Cisco equipment at the Web site http://www.cisco.com.

  3. In X.25, packets are exchanged for flow control and error control. In Frame Relay, there is no layer 3 protocol.

  4. When optical fiber is the transmission medium, the error rate is very low. Hence, the Frame Relay protocols enable fast transmission of data without the need for flow control and error control.

  5. Because low bit rate coding also gives good quality voice, the bandwidth can be better utilized. Using low bit rate coding allows fast packet transmission, so the delay will be less.
