PPPis a data link layer industry standard WAN protocol for transferring multi-protocol data traffic over point-to-point connections. With this protocol, options such as security, data compression, and network protocols can be negotiated over the connection.

Frame Relay is a packet-switching data communications protocol that statistically multiplexes many data conversations over a single transmission link. Data compression allows Frame Relay to negotiate compression over Frame Relay permanent virtual circuits (PVCs)

ISDN BRI is a switched Data Link layer control protocol which uses digital signaling to place a call into an ISDN network. Once the call is made, PPP is then used to transfer data.
