CSX400 and CSX400-DC User’s Guide

The CSX400 can be installed in a 19-inch rack with the 

included mounting brackets and screws. Refer to 

 

mounting instructions.

The same industry standard 

STAC Electronics Stacker LZS Compression algorithm supported by CSX400 software is made 
available by an optional hardware data compression module that accelerates data compression for 
the CSX400 over PPP and Frame Relay. Depending on the packet type and size, hardware data 
compression provides a minimum of 2:1 data compression, giving 3 Mbps throughput on each T-1 
WPIM interface. To use the hardware data compression module, compatible equipment (such as 
the CSX400, CSX200, and HSIM-W6 or other vendors’ equipment which conforms to the 
applicable standards), must be in use at both ends of the WAN link. When the hardware data 
compression module is installed on the board, it automatically assumes the compression task from 
software. There is no configuration necessary to prioritize hardware over software compression.

The CSX400 firmware supports IEEE 802.1d bridging, and IP and IPX routing, and OSI Layer 2 
Inverse Multiplexing (IMUX), which allows both WAN channels to be used as a single, high 
bandwidth, WAN channel. Wide Area Networking includes 

,

and ISDN. Remote access is via Full or Fractional T1, E1, Synchronous, Digital 

Data Service, ISDN BRI, 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.

The CSX400 provides a standard 802.3 Media Access Control (MAC) layer for Ethernet 
communications. All bridging and routing protocols are supported across the Ethernet link.
