1. Introduction
WRTB1xx is a family of LTE routers, used in railway applications for providing
internet access using 2G/3G/4G technology. Within the railway installation, the
router connects to local LAN network via Ethernet cable. Hereinafter in the text
it will be referred to as router.
Router contains the Master processor module with Intel Atom processor
(Master CPU hereinafter) and an Auxiliary processor module with processor
Cortex (Aux CPU hereinafter), which ensures the supplementary router
functions.
Router is supplied without application. Application is loaded by user during
installation of the device.
▪CPU Intel Atom E3815 1.46 GHz
▪2 GB DDR3L RAM
▪4 GB eMMC FLASH
▪RTC, RAM and BIOS CMOS backup by battery, optional

5. Processor modules
5.1. Master processor module
For master CPU, router uses a processor module with CPU Intel Atom.
The core contains processor Intel® Atom™ E3815 2 GB DDR3L, 4 GB eMMC.
For more details see the MSC Q7 module datasheet on manufacturer's website
(see Related documentation).
Master CPU module is equipped with eMMC (NAND flash) type memory.
Therefore, when keeping the memory lifetime in mind it is recommended to
minimize the number of writing cycles.
5.2. Auxiliary processor module
Router contains an Auxiliary CPU with CORTEX processor.
Auxiliary CPU controls modems and GPS.
The Auxiliary CPU communicates with Master CPU by Auxiliary processor
commands. By using these commands it’s possible:
▪Find-out FW version
▪Control modem power supply
