Point-to-Point Protocol (PPP)

The Point-to-Point Protocol (PPP) transports multi-protocol packets over point-to-point links. PPP is responsible for:

• Encapsulating the data packet
• Allowing the server to inform the dial-up client of its IP address (or client to request the IP address)
• Authenticating the exchange
• Negotiating multiple protocols
• Reassembling the data packet for network communication

Digi ConnectPort X devices support PPP as the connection protocol from the Digi device to the cellular IP network with NAT (Network Address Technology).
