2 About the CSX200
The CSX200 (Figure 1) is an access device that provides Ethernet Local Area Network (LAN)
connectivity via twelve RJ45 ports for the small office and offers high-speed Wide Area Network
(WAN) access to a remote site, such as the Internet or an enterprise network. The CSX200
supports IEEE 802.1d transparent bridging, IP and IPX routing, and Dynamic Host Configuration
Protocol (DHCP, Network Address Translation (NAT) routing between Ethernet LANs across a
WAN.
Figure 1 The CSX200
CSX200 Hardware
This section details CSX200 hardware capabilities.
WAN Connection
The CSX200 supports Point-to-Point Protocol (PPP) including: Link Control Protocol (LCP),
BNCP, IPCP, IPXCP, LQM, Multilink Protocol (MP) and CHAP and PAP, and Frame Relay
protocols through one of the following WAN port interface modules (WPIMs):
•The WPIM-T1 provides a T1 interface through a front panel RJ45 port and includes a built-in
Channel Service Unit/Digital Service Unit (CSU/DSU) for direct connection to a T1 line. The
WPIM-T1 provides both Full T1 or Fractional T1 using 56 or 64 Kbps Time Slots, with a total
throughput of up to 1.544 Mbps.
NOTE
The CSX201 is pre-installed with a WPIM-T1, the CSX202 is pre-installed with a
WPIM-SY, and the CSX203 is pre-installed with a WPIM-DDS.
