ATM DXI Features and Implementation Notes
ATM DXI (Data Exchange Interface) allows a link module with a synchronous
interface (that is, HSSI, V.35, or RS-449) to connect to an ATM network through
an ATM DSU/CSU (Figure 2-1).
When the router transfers data to the DSU/CSU, the DSU/CSU converts variable-
length packets into uniform 53-byte cells for transmission over the ATM network.
