E1/T1 port channel group

Figure 20 illustrates an E1/T1 port channel group. All data from the channel group is
encapsulated using frame relay protocol. The data is sent via a frame relay Serial interface and
sub-interfaces over the multiple IP interfaces defined using Data Link Connection Identifier
(DLCI).

USP port using PPP protocol

Figure 21 illustrates a USP port. All data from the USP port is encapsulated using the PPP
protocol, and is sent via a Serial interface over the multiple IP interfaces defined for the Serial
interface.

USP port using frame relay protocol

Figure 22 illustrates a USP port. All data from the USP port is encapsulated using the frame
relay protocol, and is sent via a frame relay Serial interface and sub-interfaces over the single
IP interfaces defined using DLCI.
