FIGURE 8.2 PUBLIC X.25 NETWORK EXAMPLE

X.25

A Cyclades Router can act either as a DTE (Data-terminal Equipment) connected to a public X.25 network or as a DTE or DCE (Data circuit-terminating Equipment) as part of a private X.25 network. The first case is discussed in this chapter. The second case is described in the CyROS Reference Guide. Both Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs) can be defined. A PVC requires that two DTEs be permanently connected.
