About the CSX200
The CSX200 CyberSWITCH
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, ISDN, Dynamic
Host Configuration Protocol (DHCP), and Network Address Translation (NAT) routing between
Ethernet LANs across a WAN.

CSX200 Hardware

This section details hardware features of the CSX200 CyberSWITCH.

WAN Connection

The CSX200 supports Point-to-Point Protocol (PPP) including: Link Control Protocol (LCP),
BNCP, IPCP, IPXCP, LQM, Multilink Protocol (MP), Frame Relay, and CHAP and PAP security
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 (twenty-four time slots) or Fractional T1 (less than
twenty-four time slots) using 56 Kbps-, or 64Kbps per time slot. The total throughput of the
CSX200 is 1.544 Mbps.
