Chapter 2: About the CSX200
2-4 CSX200 Installation Guide
CSX200 Firmware Support
The CSX200 firmware supports IEEE 802.1d bridging, and IP and IPX routing,. Wide Area
Networking includes Point-to-Point Protocol (PPP), and Frame Relay. Remote access is via Full
or Fractional T1, E1, Synchronous, Digital Data Service, ISDN, or HDSL connections.
This device supports industry-standard protocols, security features, compression algorithms and
network management tools to ensure interoperability with equipment from other vendors.
IEEE 802.3 Ethernet
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.
