Overview
Thank you for purchasing the Eicon 1550 or Eicon 1551 WAN Router. Eicon 
1550/1551 WAN Routers are intelligent, multi-protocol routers capable of connecting 
IP-based Ethernet devices to leased-line PPP, Frame Relay Connections, or Wide 
Area Networks via X.25. As configuration is performed through a web browser, the 
Eicon 1550/1551 is very easy to use and configure.
Hardware Features
The Eicon 1550/1551 features a 36-pin VHSI (Very High Speed Interface) port, that 
supports V.24 /RS-232, V.35, V.36/RS-449, X.21 and EIA-530 interfaces. The 
intelligent controller on the Eicon 1550/1551 detects the type of cable connected to the 
VHSI port and the actual board configuration, and then selects the matching interface.
The Eicon 1550/1551 is equipped with four Ethernet ports. You may connect up to four 
network devices (computers, printers, etc.) and in doing so, create your own local area 
network. You can also connect one of the Ethernet ports to a hub in order to 
accommodate more than four devices.
ISDN Port (Eicon 1551 only)
The Eicon 1551 is also equipped with an ISDN port, designed to be used as a backup 
in case the VHSI connection fails. More than one backup connection can be 
configured.
Upgradable Firmware
The Eicon 1550/1551’s firmware (a set of software instructions that tells the device 
how to operate) is stored in flash memory on the device. This makes it easy to upgrade 
the firmware when new versions become available.
Ease of Use
Changing settings is a straight-forward process, as parameters are accessed via a 
web browser. You can also make changes using the command line interface, which is 
accessed using a telnet application through the Ethernet connection.
About this Guide
This guide describes how to install and configure the Eicon 1550/1551 on any 
computer capable of supporting an Ethernet card and TCP/IP. The installation 
instructions complement those found in the Quickstart Guide, which is also included 
with your package. 
Note, however, that it is presumed that the user is familiar with the configuration and 
function of X.25, PPP, networking, and other related fields. If you are unsure of how to 
configure the device, consult your network administrator.
For instructions on setting up communications protocols and using applications that 
access the external network, consult the documentation provided with your software.
