MLPoFR

MLPoFR (Multilink PPP over Frame Relay)

Frame Relay does not natively support features such as authentication,
link quality monitoring, and reliable transmission. By using PPP over Frame Relay these these features can be enabled. A useful feature of PPP that can be used over Frame Relay as well is PPP multilink: Multilink PPP over Frame Relay (MLPoFR).
