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).

Figure 4.3 illustrates a USP port. All data from the USP port is encapsulated using
Frame Relay protocol, and is sent via a Frame Relay Serial interface and
Sub-interfaces over the single IP interfaces defined using DLCI.
