1. Introduction
3G networks
New research in the field of telecommunications has led to the extension of the range of
services provided to the users, especially in the mobile communications networks. Today, 3G
mobile networks dominate the world market. The TOPEX Group is promoting the advanced
facilities provided by the CDMA or UMTS wireless network, by manufacturing several ranges
of products that including BYTTON UMTS.
These 3G wireless devices are new electronic equipment, of compact size, which use
an updated design and are easy to mount and install. The economic benefits of Topex user-
network interfaces are considerable. By using these services you can perform several
activities at the same time, such as data transmission, Internet connection, voice call,
checking of geographical coordinates by GPS.
The high data transfer speed specific to the third generation communications network
leads to an increased efficiency of information transmission, while the real time access to
data and information means important savings of time and money.
UMTS, Universal Mobile Telecommunications Service, part of the IMT-2000 initiative,
is a 3G standard supporting a theoretical data throughput of up to 2 Mbps. The UMTS
system maintains compatibility with widely used GSM/GPRS networks, but assures higher
quality and faster data transfer, thereby enabling the development and better use of services
and contents, both already developed and new ones. UMTS is based upon wideband CDMA
(WCDMA) technology. CDMA digitally encoded technology ensures connections with
exceptional security. CDMA virtually eliminates cloning and other types of fraud because of
the 4.4 trillion codes used, while the spread spectrum signal provides the greatest coverage
in the wireless industry. CDMA networks are built with standard IP packet data protocols.
The UMTS definition of 3G is 384 Kbps fully mobile and 2 Mbps low mobility/fixed
wireless. Also, unlike competitive mobile broadband technologies, it supports simultaneous
voice and data transfer.
WiFi
Wireless LANs are complementary extensions to existing wired LANs, offering complete
mobility while maintaining continuous network connectivity to both corporate and home
Intranets. PC users stay connected to the network anywhere throughout a building without
being bound by Ethernet cables or other LAN wires. This is accomplished through the use of
Access Point functionality of BYTTON UMTS. The TOPEX equipment with built-in Internet
gateway capability allows your house or company to share an UMTS account or other
broadband connection, working simultaneously from different rooms, without need for cables
or wires. The embedded Access Point of the TOPEX Gateway complies with wireless
standards IEEE 802.11g and 802.11b. The 802.11g is as extension to 802.11b (used in
majority of wireless LANs today) that broadens 802.11b’s data rates to 54 Mbps within the
2.4 GHz frequency band using OFDM (orthogonal frequency division multiplexing)
technology.
In order to ensure a correct installation / configuration and a good operation of the
BYTTON UMTS equipment, the manufacturer strongly recommends you to study this manual
before attempting operation.
System Requirements
To be able to use BYTTON UMTS gateway, you must fulfill these minimum requirements:
• UMTS Mobile Broadband Internet Account.
• An Ethernet (10Base-T or 10/100Base-TX) adapter for wired client
• At least one 802.11g (54Mbps) or one 802.11b (11Mbps) wireless adapter for the wireless
mobile clients (desktop PC’s, notebooks, peripherals)

3. What is BYTTON UMTS?
The BYTTON UMTS equipment is versatile
advanced router for wireless broadband Internet
access using 3G technology. Also, it is a voice and
data interface between a PBX exchange and
GSM/GPRS/UMTS mobile network.
As data router, BYTTON achieves a direct
connection, transparent for the user, between the
local network (Ethernet and/or WiFi) and the
GSM/GPRS/UMTS mobile communications
network.
For wireless WAN connection, it uses an embedded
radio modem for the UMTS mobile network. Its 3G
capabilities assure high speed Internet access up to
384 Kbps. This is really broadband mobile Internet,
at data rates many times greater than a dial-up
connection or networks. Still, if you are in an area
where you have only GSM or GPRS coverage, you
may use BYTTON in conjunction with the
respective networks.
As a voice interface, it allows wireless connection
of the local subscribers and decreases the cost of
fixed–to-mobile and mobile–to-fixed calls. BYTTON
achieves a direct contact between a trunk or a local
subscriber extension of a PBX over the mobile
network. This way the fixed-to-mobile calls are
converted into mobile-to-mobile calls. Thus you will
pay only the mobile-to-mobile cost.
Since BYTTON UMTS features both FXO and FXS
interfaces, it is highly versatile: you may connect it
either to a trunk of the phone exchange or to a local
extension of the same phone exchange. The
parameters of the FXO and FXS interfaces are
software programmable, by means of the web
interface. This facility is very helpful when your
phone exchange has only ISDN interfaces or there
are no available analog trunks (all of them are
used).You can make calls while browsing,
performing uploads, streaming video, etc. Unlike
other devices, BYTTON has full simultaneous voice
and data capabilities – you may perform at the
same time high speed data transfer and voice calls.
By using BYTTON UMTS, you are no
longer dependent of a fixed connection, so
you may connect your LAN network to the
Internet even in remote areas where there
are no fixed connections (phone line,
cable, optical fiber, etc).
Still, If you want, you can also use the
WAN connection to interface with other
Internet providers than the UMTS network,
such as DSL cable modems, other
wireless broadband modems.

Our product is fully mobile, since it uses
wireless connections not only for LAN and
WAN, but also for configuration. No cables
at all are required, except for power!
BYTTON UMTS operates as a local server
(router), since it provides access to an
outside network and routes the packets in
the local network. The structure of
messages is transmitted using standard
communications protocols (TCP/IP, PPP,
etc). These messages are fully controlled
and traceable. All computers on the wired
or wireless local network can access the
Internet through the Topex UMTS Router,
using only a single external IP address.
You may easily change the operating
parameters of BYTTON to fit your
needs by remote secure (https) access
using a web browser.
The configuration process is user –
friendly. The changes you make can be
stored in the non-volatile memory
(Flash) of the device or saved as files
on the hard disk drive.
One can rest assured that the local area network
connected to our product is safe because we have
implemented a very powerful firewall and intrusion
detection system.
The Topex BYTTON UMTS Router makes usage of
NAT (Network Address Translation) and SPI
firewall to ensure protection for your local network,
wired or wireless.
The features of the firewall are identical to those
available to Linux servers throughout the world,
which are well renowned for their safety.
Because our product is 100% Linux based, applications to enhance BYTTON UMTS or to
customize it can be quickly designed by our software developers, according to the special
needs of various clients.
Our best Linux experts are available for your technical questions around the clock, if you
sign up our technical support offer. In addition, the software upgrades can be done remotely
via Internet, and are free of charge.

4. Installation
In order to ensure the proper operation of the BYTTON UMTS equipment you must
follow the set-up steps shown below:
•Establish the best location
•Mounting (Hardware installation)
•Identification of connectors
•Connecting the data cables
•Connecting the phone cables
•Configuring and installing the SIM card
•Connecting the external antennas for UMTS and WiFi
•Setting the PIN or PUK code, if required
•Power up
4.1 Establishing the best location
In order to determine the best location for the TOPEX router please have in mind
these considerations:
• If you use wired connections, the length of the Ethernet cables that connects the TOPEX
EDVO routers the network must not exceed 100 meters.
• BYTTON UMTS should be placed on a flat, sturdy surface located as far from the ground
as possible. The on top of a desk or a shelf is best both for the UMTS connection and for the
Access Point. Also, BYTTON should be kept clear of obstructions and away from heat
sources, direct sunlight and heavy-duty electrical equipment.
• To ensure good coverage to all of the wireless mobile devices in your area BYTTON UMTS
should be installed in a central place in the building. Normally the antennas should be in
vertical position, but if reflections occur, you may get better results by changing their
orientation.
• For power supply, use only the adapter shipped with BYTTON. The jacks of different power
supplies may fit but the polarity, current, voltage or regulation factor may not be compatible.
• While the device is in operation, the antennas of the BYTTON UMTS unit should be at least
30 away centimeters from any human being.
4.2 Mounting (hardware installation)
Mounting the TOPEX BYTTON UMTS router means simply placing it on a flat, horizontal
surface. The surface must be level and strong enough to hold the weight of BYTTON UMTS
together with its cables (power supply, wired LAN connections, telephone, USB etc). A desk,
table or shelf is good place for the installation of BYTTON.
The best location for BYTTON UMTS is in the middle of the place where you want to
have wireless coverage. Installing BYTTON on a shelf higher up, with no obstructions
around, ensures the best performance, both for WiFi and for the UMTS modem.
If you have several BYTTON UMTS units, they can be stacked one over another.
Take care to ensure adequate cooling of the Topex devices. This version of the equipment is
NOT designed for wall-mounting (vertical position).
4.3 Identification of connectors
Topex BYTTON UMTS features several external connectors, as described below.
On the back panel of the equipment there are, from left to right:
