1. INTRODUCTION
Embedded Modem
The embedded modem of BYTTON is a HSDPA/UMTS/GPRS/EDGE/GSM multi-mode device. It
measures in real-time the RF signal level strength of the mobile network and lets the user to freely
choose the 2G/3G network. Thus it provides access rates up to the maximum possible for each 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 high speed networks such as
HSDPA/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!
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 HSDPA.
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
HSDPA equipment, the manufacturer strongly recommends you to study this manual before attempting
operation.

3. What is BYTTON HSDPA?
Still, if you are in an area where you have only UMTS or
GPRS or even GSM coverage, you may use BYTTON in
conjunction with the respective networks.
The BYTTON HSDPA equipment is
versatile advanced router for wireless
broadband Internet access using 3G
technology.
At the same time, it is a voice and data
interface between a single phone or a PBX
exchange and GSM/GPRS/EDGE/HSDPA
mobile network.
As data router, BYTTON achieves a direct
connection, transparent for the user,
between the local network (Ethernet and/or
WiFi) and the
HSDPA/GSM/GPRS/EDGE/UMTS mobile
communications network.
For wireless WAN connection, it uses an
embedded radio modem for the HSDPA
mobile network. Its 3G capabilities assure
high speed Internet access.
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).
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 HSDPA 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.

TOPEX BYTTON HSDPA User’s Manual
pag. 10
All computers on the wired or wireless local network can access the Internet through the Topex HSDPA
Router, using only a single external IP address.
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 HSDPA 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.
This firewall is fully configurable, but it is also easy to use for
beginning users.
Because our product is Linux based, applications to enhance BYTTON HSDPA or to customize it can be
quickly designed by our software developers, according to the special needs of various clients.
Our best technical 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 HSDPA 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 HSDPA 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 Bytton routers
the network must not exceed 100 meters.
• BYTTON HSDPA should be placed on a flat, sturdy surface located as far from the ground as
possible. A high location, on the wall or on top of a desk or a shelf is best both for the HSDPA
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 HSDPA
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 HSDPA unit should be at least 30
centimeters away from any human being.
4.2 Mounting (hardware installation)
The Topex BYTTON HSDPA router may be mounted either horizontally, by means simply placing
it on a flat surface, or vertically on a wall (using the mounting kit).
Horizontal mounting
The surface must be level and strong enough to hold the weight of BYTTON HSDPA 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. . In this case, the WiFi antenna should be in vertical position (at right
angle to the box of the equipment)
Wall mounting
The equipment may also be mounted on a wall, by means of the kit included in the package.
It is recommended you use a pattern to secure the device to the wall. Also, you should use professional
installation to reduce the risk of injury and damage. In this case also the WiFi antenna must be in upright
vertical position, but it will be parallel to the equipment’s box.
For mounting BYTTON HSDPA on a wall you should use the mounting kit (plastic dowels, woodscrews,
etc) provided by Topex.
On the back there are two pairs of mounting holes, 160 mm apart. The two pairs are located 100 mm one
from another, allowing you to fasten BYTTON to the wall either connectors up or indicators up.

TOPEX BYTTON HSDPA User’s Manual
pag. 12
Perform the following steps:
- mark on the wall the position of a pair of holes,
spaced at 160 mm apart
- drill the holes in the wall
- forcibly insert into the holes the plastic dowels
- thread the metallic woodscrews into the plastic
dowels leaving the end to protrude outside for
some 5 mm
- hang the case of BYTTON HSDPA in the two
metallic woodscrews and push it down a little to get
it fixed
- if it does not lock properly, you should adjust the
screws
Figure 1. Mounting BYTTON HSDPA on a wall
No matter if it is installed horizontally or vertically, the best location for BYTTON HSDPA 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 HSDPA modem.
Take care to ensure adequate cooling of the Bytton terminal.
4.3 Identification of connectors

4.4. Connecting the data cables
To ensure a proper functioning of the BYTTON HSDPA unit, you must make the right cable
connections, as described below.
Figure 3: Connecting the cables
For local network connection:
Use standard UTP network cables (CUT 5) fitted with RJ45 connectors at both ends. The cables
can be either straight-through or crossover, since the switch of BYTTON HSDPA is auto-crossover. One
short length of RJ-45 cable is supplied with the TOPEX BYTTON Router. You may use either 10Base-T
or 100Base-T connection, and both types of Ethernet connections maybe used on the same time.
The network cables are to be inserted with one end into the RJ-45 sockets of the BYTTON HSDPA
equipment labeled LAN1 to LAN4. The opposite end of the UTP cable can be inserted directly into PCs
or in switches or hubs. The corresponding LED indicators of the front panel should light up, showing
physical connection and data traffic on the respective Ethernet interface.

TOPEX BYTTON HSDPA User’s Manual
pag. 14
For WAN connection:
Plug one end of the
cable into the RJ45
port labeled “WAN” on
the rear of the TOPEX
BYTTON HSDPA and
the other end into the
Ethernet port of the
ADSL or Cable
modem.
For Wireless connection:
When a wireless device enters in the coverage area of BYTTON, it will be automatically
connected. For settings, refer to the User manual of your wireless adapter for associating with the
BYTTON HSDPA router. The default SSID of the TOPEX router is “ByttonHSDPA”, encryption is
disabled and open system authentication is used. You can modify these default settings as you wish.
For USB connection:
Plug the USB cable of the
device into one of the USB slots
of the BYTTON HDSPA
equipment.
Currently it supports USB
webcams that are compatible
with PWC Linux drivers. For
details see
http://www.saillard.org/linux/pwc
/.
Development in progress will
allow also connection of various
USB devices or peripherals,
such as printers, scanners,
HDD or Flash card readers for
extended storage.
If you need to connect several USB devices to Bytton, you should use an USB hub to “multiply” the
single USB slot of the Bytton equipment.

TOPEX BYTTON HSDPA User’s Manual
pag. 15
4.5. Connecting the phone cables:
You may use one of the phone interfaces, either FXS or FXO. For connection, BYTTON HSDPA is
shipped with a flat telephone cable, wired on both side with male RJ11 connectors.
Connecting the telephone cable for FxS interface
Connect the telephone cable with
one of the end to the FXS connector
of BYTTON and the other end to an
analog trunk of PBX.
Should the phone exchange have
terminal trunks not equipped with RJ-
11 connectors, you must connect the
two middle wires of telephone cable
directly to internal connector of the
PBX exchange.
Alternately, you may connect the
telephone cable with one of the
end to the FXS interface of
BYTTON HSDPA and the
opposite end directly to a standard
(fixed) phone.
In this case you won’t have the
routing facilities of the phone
exchange, but you still be able to
make voice calls while transferring
files or browsing the Internet.
Note: BYTTON HSDPA features analog phone interfaces, so it must not be connected to an ISDN
interface (digital trunk) of PBX exchange. For connection to an ISDN exchange you should use
wireless equipment specially designed for ISDN phones. Improper installation of BYTTON HSDPA
equipment might lead to damage of BYTTON or PBX. (If you join a local subscriber line of PBX exchange
to the FXS connector of BYTTON then both equipment will generate current into the connection cable, so
the Bytton router and PBX the exchange could be damaged).

TOPEX BYTTON HSDPA User’s Manual
pag. 16
Connecting the telephone cable for FXO interface
If you use the FXO interface of BYTTON HSDPA, connect the phone cable with one of the end to the
FxO connector of the equipment, and the other end to a line interface (local extension) of your PBX.
Take care NOT to connect the FXO interface to a trunk (outgoing line) of the PBX.
Also, the FXO interface of BYTTON must be properly configured (use the Web interface to change the
settings).
Figure 4: Connecting the telephone cable for FXO interface
Note: In this case, if no restrictions exist for subscriber access rights assigned for extension where
BYTTON HSDPA was installed, any caller from fixed network who rings to the BYTTON number can
obtain the access to outgoing trunks. So his calls will be billed to the owner of the PBX.
For avoiding this you have the following solutions.
- either configure the phone exchange to reject the outgoing calls on the extension where BYTTON
HSDPA interface is connected
- or set the BYTTON HSDPA equipment so that when it receives a call from mobile network, it will
automatically direct the call to a specified extension (generally the operator’s desk).
For power supply:
To power the BYTTON unit, just insert the jack of the power supply adapter into the supply
connector. Do not yet plug the adapter into the 230VA.C. mains outlet on the wall. The special adapter
from Topex, which is part of the Bytton HSDPA package, supplies the voltage required to power the
equipment. It is an external power supply adapter.
Note: The adapter is the disconnection device (there is no POWER switch), so the 230 VAC socket-outlet
shall be installed near the equipment and shall be easily accessible.
Figure 5: Connecting the power supply

TOPEX BYTTON HSDPA User’s Manual
pag. 17
Warning !
Use only the power supply adapter shipped in the equipment package. Using of other kinds of
power supplies may cause damage to the equipment.
To avoid accidents or damage to the equipment, follow the steps described earlier. First,
connect the antennas, and then the power supply adapter.
You should avoid connecting or removing the antennas while the BYTTON HSDPA equipment
is powered.
4.6. Configuring and installing the SIM card
In order for the BYTTON HSDPA router to work, it must have a valid SIM card with subscription to the
GSM/GPRS/EDGE/UMTS/HSDPA operator where you want to connect to.

4.7. Connecting the external antennas
To ensure a good quality of transmission and reduce radio interference use the antennas shipped in the
BYTTON package. These antennas are for the respective frequency bands (multiband for
GSM/GPRS/EDGE/UMTS/HSDPA network and 2,4 GHz for WiFi).
The antennas must be connected to BYTTON HSDPA via the respective RF circular connectors on the
back panel of the case. The cable for HSDPA antenna must be threaded into the circular connector of
BYTTON HSDPA labeled “GSM/3G”, while the stick antenna for WiFi into the other RF connector (to the
right) as shown in the following drawing.
Note that the connector for the Mobile network is female, while the one for WiFi is male (with protruding
pin) so there is no risk of inserting the incorrect antenna.
Figure 6: Antenna attachment
If your site has low level of 3G signal, it may not be possible to use the full HSDPA technology without a
special, high gain antenna. You should get such an antenna and install it in a higher position (the roof of
the building), directed towards the base station of the mobile network carrier, in order to get best results.
Warning! Don’t use excessive force. Make sure the antennas are securely screwed into the RF
connectors, but do NOT use a spanner or screw key, which could damage the antenna connectors!
Tighten the flange lightly, by hand.
The antennas have vertical polarization, they should be placed in vertical or horizontal position,
depending of the local field condition.
!You should fasten the antenna on a safe
(with great stability) and flat area, even
one that is not magnetic.
The following table shows the main characteristics of the multi-band stick antennas with magnetic
base (currently supplied with the BYTTON HSDPA package).

Notice:
The BYTTON HSDPA unit and its antennas should be placed such as to be as far as possible
from appliances or office equipment that is sensitive to radio interference (microwave ovens,
copiers, TV sets, PC displays, and multimedia systems). For best results, try to find for the
HSDPA antenna a place of maximum signal reception.
In addition, the antenna must NOT be located near heavy-duty equipment that may generate
electromagnetic interferences, such as electric motors or heaters.
4.8. Power up
Power up BYTTON HSDPA by inserting the adapter into the wall outlet. The Topex router will start
working. You should see the PWR indicator LED lighting up.
4.9. Status indicators
BYTTON HSDPA several optical indicator (green or bicolor LED) that shows the status of the
device. This indicator light up continuously or flash to show data traffic. In normal operation the LAN,
WAN, WiFi or respectively NET indicators must be blinking. The LINE indicator shows the active status
of the phone line.
Figure 7: LEDs location
GSM / 3G – Green LED. Off indicates no mobile network connection, On = data connection
active.
LINE – Red LED. Lights up to show the phone interface is in use. When it is ON, it indicates the
phone line (FXS) or the junction (FXO) is engaged.
PWR – Green LED. Off = no power, On indicates that BYTTON HSDPA is powered. . Of course,
if the power supply voltage is off, no indicator LED will light!
WiFi – Green LED. Off = not in operation, On = wireless system ready, blinking indicates activity
of the embedded 802.11 b/g Access Point
WAN – Green LED. Indicator for the WAN Ethernet connection. Off = no cable connected, On =
physical connection to Ethernet network (an UTP cable was connected to the respective input), flashing
= shows data traffic (send or receive) through that connector
LAN 1 … 4 – Green LED. Off = no cable connected, On = physical connection to Ethernet
network (an UTP cable was connected to the respective input), blinking = shows data traffic (send or
receive) through that connector. Note that the four LAN indicators are numbered in direct order, as to
correspond to the LAN connectors on the opposite side.
