Bridge capability
– you may define several bridges between up to four interfaces of the equipment,
- each bridge may be considered a kind of software switch that can be used to connect multiple Ethernet
interfaces (either physical or virtual), while sharing a single IP subnet
- bridging a physical eth network interface of Bytton with an Open VPN-driven network tap interface at
two separate locations, both distant Ethernet networks are merged as if they were a single Ethernet
subnet.
OVPN available
–in addition to other kinds of versatile, advanced tunneling that may be for VPN, Bytton provides support
for the OpenVPN Client;
–OpenVPN is simple, very easy to install and configure
–it can be installed on nearly any platform, the configuration principle remains the same on any platform
–TAP/TUN interface options are available so you can choose to build either Ethernet (Bridged) or IP
(Routed) VPNs with the embedded OVPN software.
Virtual Routing Tables
- the Virtual RT feature acts like a logical router, using a single routing table for each instance
- provides a way to configure multiple routing instances on a single hardware router
Easy Firmware Updating
– automatic update process using the web configuration interface, locally or remote
Low Power Consumption (less than 10 Watts)
– the low power consumption means reduced heat dissipation, hence no cooling fans required
– no moving parts means you get higher reliability and no noise.
Serial Interfaces
- variant with one or two programmable serial (RS-232) interfaces available; the serial interface allows
remote control of “legacy” devices – older equipments that feature a serial interface
- TCP server option lets you to remotely access the serial interfaces via telnet.
Diversity antennas - MIMO Enabled
- both the 3G+ modem and the WiFi access point of the equipment are available in MIMO variant - with
two antenna connectors each; the usage of multiple antennas for diversity ensures higher speed,
increased throughput or better signal quality.
Flexible ETH port assignment
– the wan0/lan0 connector may be assigned, form the Web configuration interface, either to the LAN or
to WAN/LAN (a second remote network)
- the local ETH ports may be grouped in a switch according to your requirements: all three, just two, or
they can be allotted individual IP addresses for each; you can specify for every ETH port the speed,
auto-negotiation feature, operation in full duplex of half duplex mode.
.
Advanced firewall
– SPI firewall with “iptables” for filtering and NAT, fully configurable from the Web pages.
Static and Dynamic routing
– You may completely define several static routes, using Quagga or Kernel for routing
– Quagga routing program (RIP, OSPF and BGP protocols implemented)
Advanced functions for the "superuser"
– this login mode allows access to additional items in several Web configuration pages, while the section
“Stuff” provides reporting via e-mail, self-provisioning by loading configuration files and testing the
bandwidth
Various "services" available
–besides the basic capabilities, of Voice and Data over advanced mobile networks, the Services section
povides different additional features, such asa SNMP, VRRP, Telnet, email-2-sms, DDNS, NTP client,

1. INTRODUCTION
Embedded Modem
The embedded modem of Bytton ICR may be a 4G (LTE) or 3.5G (HSPA+) or 3G (UMTS/HDSPA)
engine multi-mode device, downwards compatible with 2G (GPRS/ EDGE/ GSM) networks.
It measures in real-time the RF signal level strength of the mobile network and lets the user to freely
choose the 2G or 3G+ network. Thus it provides access rates up to the maximum possible for each mobile
voice/data network. This way you may talk, download files or surf the Web without cabled connections
almost anywhere, at any time.
When you are out of the coverage of very high speed networks such as LTE or HSPA/UMTS, you
can still get services on the wireless Internet with alternative access via GPRS/EDGE/GSM network in
your area.
The embedded multiband modem covers almost all of the frequency bands of the world (multiband
for LTE, dual band for UMTS/HSPA+ and tri-band or quad band for GSM/GPRS/EDGE!
Serial interface(s)
For connection to legacy devices, Bytton LTE can feature one or two configurable RS-232 or RS-
485 ports on the front panel.
By means of the Web configuration menu you may control the serial interface (RS232) of Bytton
LTE and its associated IP services.
Figure 1-1: Bytton LTE featuring one or two RS-232 ports (SER1, SER2).
Note: Your actual equipment may not look exactly as described above!

TOPEX Bytton (HSPA+ / LTE)

Page: 17 / 290
Available variants
Bytton is a very versatile equipment; it features inside one motherboard that can get several types
of plug-in daughter boards, according to the functions requested by the customer. Because of this, your
actual equipment may not look identical to the pictures presented in the manual, and may not have all the
features described. The main variants / options are:
several types of mobile modules, for 2G or 3G+ networks (UMTS, HSDPA, HSPA+), and even
LTE (assuring up to100 Mbps peak download rate), or for different frequency bands:
850/900/1800/1900 MHz for GSM/GPRS/EDGE, 2100 MHz for HSDPA or HSPA+,
800/900/1800/2100/2600 MHz for LTE and so on. The external aspect of the equipment remains
the same for all variants of modules, but the capabilities (and price!) are different. Some type of
modules feature antenna diversity (MIMO capabilities): connection of two Mobile antennas, for
diversity reception or for achieving higher data rates. Thus, special Bytton equipments may
feature four antenna connectors, two for the MOB mobile data network (HSPA+, LTE) and two for
the embedded Wi-Fi module. GPS capability is also available, for mobile units, powered form the
car battery;
no voice capabilities and no Wi-Fi, with two data SIMs (not concurrently) for higher availability
and with serial interface(s) for legacy devices. It has holders for two data SIMs; the device may be
used with one or two SIM cards. It may feature one serial interface (SER2).
still no voice capabilities but with Wi-Fi for wireless local connection, a single data SIM. The four
Ethernet connectors are present In this case the connector for Wi-Fi antenna is present, located
near the center of the front panel, together with the corresponding indicator LED for Wi-Fi. No
serial interface!
with voice capability (one FXS interface located to the left) and also with Wi-Fi, one voice/data
SIM card. The connector for Wi-Fi antenna is present, together with the corresponding LED for
Wi-Fi. Since there are not two mobile modules (it cannot perform LTE for two mobile carriers), the
variants with telephone port always use a single SIM card.
BYT_4G_FC1/ BYT_3G_FC1, the variant with one serial interfaces, labeled “SER”, available for
connections to legacy equipments. No voice capabilities, no Wi-Fi antenna and hence no Wi-Fi
indicator, a single SIM card. The RS-232 interface feature RJ-45 connectors on the front panel.
the Lite (low cost) variant of the equipment, a Topex Bytton LTE with no voice capabilities and no
Wi-Fi, a single data SIM, and no serial interfaces. Out of the four Eth ports, there are two LAN
ports, one configurable WAN0/LAN0 port, and the dedicated WAN port;
There is an even simpler variant, with no SIM and hence mobile data capability, used as an
advanced network router. The front panel features just four ETH ports, one SER.
Advanced variants with one or two serial interfaces, and one or two SIM cards besides the Mobile
antenna and the four ETH ports. The two serial ports labeled “SER1” and respectively “SER2” are
available for connections to legacy equipments. The RS-232 interfaces feature RJ-45 connectors
on the front panel. The phone line interface (FXS) is missing, but the Wi-Fi access point can be
present, for wireless connection of equipments in the field. The front panel features, from left to
right: the circular antenna connector Mob, two SER connectors, the round Wi-Fi connector for
wireless antenna, the four Ethernet connectors (WAN, WAN0/LAN0, LAN2, and LAN1), the
recessed Reset button and the PWR jack for power supply!

Page: 18 / 290
-the most advanced variants, with full complement of features: two serial interfaces, two SIM cards, also
FXS interface for analog fixed telephone and USB connection.
The serial ports labeled “SER1” and respectively “SER2” are available for connections to legacy
equipments. The RS-232 interfaces feature RJ-45 connectors on the front panel. To the right of the
serial connectors, there is also a slot for USB 2.0.

for USB.
Note: This picture may not be identical to the aspect of your own Bytton router!
-Antenna diversity versions.
These Bytton equipments may feature with two connectors for MOBILE antennas and also two connectors
for Wi-Fi. Thus it features up to four antenna connectors, labeled MAIN and respectively AUX both for the
mobile data network and for the embedded Wireless Access point:
Both the LTE modem and the embedded Wi-Fi access point of Bytton LTE have MIMO capabilities,
meaning they can operate with two antennas for achieving diversity (higher bandwidth or higher tolerance
to perturbations, thus achieving increased capacity and / or robustness). There are several sub-variants
of MIMO Bytton equipments available, for instance, as you can see in the photo, it may have two antenna
connectors for the mobile data network, but only one connector for the Wi-Fi antenna!
Figure 1-3: Drawing and photo of antenna diversity: up to two antennas for Mobile and Wi-Fi.
The advanced variants with FXS port and respectively with USB slot, and also the special
version with up to four antennas, are available only upon special request!
In order to ensure a correct installation / configuration and a good operation of the Bytton LTE equipment,
the manufacturer strongly recommends you to study this manual before attempting operation.
