The CSX200 provides a standard 802.3 Media Access Control (MAC) layer for Ethernet 
communications. All bridging and routing protocols are supported across the Ethernet link.

This device supports the following WAN protocols over the WAN port:

Point-to-Point Compression Control Protocol (CCP) as defined by RFC 1962

Dynamic Host Configuration Protocol (DHCP) as defined by RFC 1541

Network Address Translation (NAT) routing as defined by RFC 1631

Point-to-Point Protocol (LCP) as defined by RFC 1661

Point-to-Point Protocol (BNCP) as defined by RFC 1638

Point-to-Point Protocol (IPCP) as defined by RFC 1332

Point-to-Point Protocol (IPXCP) as defined by RFC 1552

Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol 
(CHAP) under PPP as defined by RFC 1994

Point-to-Point Protocol Line Quality Monitoring (LQM) as defined by RFC 1333

Point-to-Point Protocol Multilink Protocol (MP) as defined by RFC 1717

Frame Relay Link Management Interface (LMI) as defined by ANSI T1.617 Annex D and ITU 
Q.933 Annex A

Frame Relay Data Encapsulation as defined by RFC 1490

Frame Relay Data Compression Protocol (DCP) as defined by FRF.9

PPP is 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. Data compression allows Frame 
Relay to negotiate compression over Frame Relay permanent virtual circuits (PVCs).

Frame Relay is a packet-switching data communications protocol that statistically multiplexes 
many data conversations over a single transmission link.
