AI2524 Router Card User’s Manual

Example: Hybrid DTE/DCE PVC Switching

Routers can also be configured as hybrid DTE/DCE Frame Relay switches (see Figure 13-6).

Figure 13-6:Hybrid DTE/DCE PVC Switching

In this example, Router B acts as a hybrid DTE/DCE Frame Relay switch. It can switch frames between the two DCE ports and between a DCE port and a DTE port. Traffic from the Frame Relay network can also be terminated locally. In the example, three PVCs are defined as:

z	Serial 1, DLCI 102 to serial 2, DLCI 201—DCE swit ching
z	Serial 1, DLCI 103 to serial 3, DLCI 301—DCE/DTE swi	tching
z	Serial 2, DLCI 203 to serial 3, DLCI 302—DCE/DTE swi	tching

DLCI 400 is also defined for locally terminated traffic.
