Figure 4.1 T1 Port with PPP Encapsulation

Figure 4.2 illustrates an E1/T1 port Channel Group. All data from the Channel Group is encapsulated using Frame Relay protocol, and is sent via a Frame Relay Serial interface and Sub-interfaces over the multiple IP interfaces defined using DLCI (Data Link Connection Identifier).
