Introduction The Prestige converts frame relay/HDLC (High-level Data Link Control) frames to ATM (Asynchronous Transfer Mode) cells from the LAN to the WAN and vice-versa via channels. The encapsulation type you select, when configuring individual channels, determines the how frames/cells are converted.

  • Page 36: Networks

    Prestige 724 G.SHDSL CSU/DSU 3.1.2 Networks Asynchronous Transfer Mode (ATM) is a popular end-to-end, high-performance, cell-oriented switching and multiplexing technology that uses fixed-length cells to carry different types of traffic from source to destination. A virtual channel connection is the basic unit of ATM that carries a single stream of cells, in order, from one switch to another until the cells reach their final destination.
