2 ABOUT THIS DOCUMENT
This configuration manual is intended for system developers and integrators. It is not intended for end users. It
describes the firmware functions of the access point/router/gateway product family and provides information for
special applications and configurations of the product.
This manual is intended to guide through the configuration process of an Access Point/Router/Gateway (the names
of which are used interchangeably for this manual) for use in a train or bus. We tried to cover the main aspects of
this task, including
•Backup and restore of configurations
•Install new firmware versions
•Handling of IP addresses, DHCP, VLAN, VPN, firewall
•Configuration of WiFi and LTE
•MWAN configuration for multiple WAN connection
•Westermo Eltec’s train coupling, wireless backbone protocol ICCP
•Remote administration via SNMP
•Scripting and UCI.
Not covered is a complete list of all functions and of all configuration elements in detail.
Information about mechanical and electrical installation of the access points is available in a separate
product-specific installation manual which can be downloaded from the Download Center at www.eltec.com.

3 ABOUT THE CyBox LTE 2
The CyBox LTE 2 is a member of the CyBox family of robust wireless communication routers. It is particularly
designed to meet the requirements of rolling stock applications. It offers stable, secure, and broadband LTE
connections for train-to ground communication and high-speed internet.
The CyBox LTE 2 hosts up to two LTE interfaces or one Wi-Fi 5 interface combined with an LTE interface to boost
network efficiency and connect to client devices such as mobile phones. Country-specific LTE/Wi-Fi standards are
adopted for worldwide use in every type of train.
The CyBox LTE 2 firmware provides a convenient management interface via a web service. Besides global setup
parameters the open source software allows the configuration of the radio interfaces, such as channel selection,
SSID, encryption keys, and firewall setup. The access point and router configurations as well as the management
firmware can be updated remotely.
The firmware of the device is based upon Linux and OpenWRT. For Open Source information see the preface.
