SECTION 1 –

Product Presentation

1

This section presents the 2N VoiceBlue Enterprise product
including its application options and advantages.

Here is a survey of what you will find in this section:

• Purpose of the product;

• Application possibilities;

• Instructions how to save telephone costs;

• Overview of interesting and useful properties.

1-2 2N® VoiceBlue Enterprise

1.1. Purpose

• The 2N VoiceBlue Enterprise gateways provide direct

interconnection of VoIP and GSM networks with the aid of SIP
signalling protocols.

• The voice mode, i.e. an outgoing or incoming call, is the basic

function of the system. The gateway is equipped with all
functions necessary for such use and provides a very high
comfort in this mode.

• In addition to voice transmission, 2N VoiceBlue Enterprise can

send and receive short text messages. For remote control
purposes, diagnostic SMS can be sent in regular intervals from
the gateway to a selected mobile number. These additional
functions enhance the utility value of the product.

• 2N VoiceBlue Enterprise contains a built-in SIP proxy server

and can thus serve as a PBX for SIP telephones. However, the
use of the gateway is not limited to this SIP proxy function
only, it can be applied with any SIP supporting PBX.

• No extra equipment (an external GSM telephone, etc.) is

needed for normal operation. All programmable parameters are
default-preset in such a manner that you can commence your
telephone traffic the moment you connect the Ethernet and
supply cables, antenna and SIM card and set the IP parameters.

1.2. How to Save Telephone Costs

• Once your 2N VoiceBlue Enterprise gateway has been

connected to your VoIP PBX, all calls going out to a mobile
network are made directly. This saves your PSTN - mobile
network call costs. The mobile telephone calls of your
personnel in the field are cheaper too.

• You are advised to use the most advantageous tariff of your

GSM provider for your GSM gateway because all gateway

user call accounts are added up for billing purposes.

• If you use a call answering machine as a GSM network

service, you pay for your voice message deliveries as a rule.
However, if you connect your answering machine to the GSM
gateway, you pay nothing for your voice message deliveries.

Product Presentation 1-3

• You can bar selected numbers or groups of numbers in your

gateway. You shall pay nothing for the calls you have
barred.

• 2N VoiceBlue Enterprise keeps detailed records on all calls.

This helps you find out easily why your bill is higher than it
should be.

• The Least Cost Router is flexible enough to help you set rules

for GSM calling at the lowest possible operation costs.

1.3. Other Advantages and Applications

• VoIP-GSM gateways integrate the best of their respective

communication technologies.

• With the aid of a built-in SIP proxy server you can create a

complete VoIP network without additional third party
products' costs.

• The intelligent routing of incoming calls accelerates the

connection of incoming calls and makes calling more
comfortable.

• An easily recordable DISA voice message function is

available.

• You can use the conditioned or unconditioned call forwarding

function.

• Unlike mobile telephones, this system does not expose you to

the RF electromagnetic field while making calls.

1-4 2N® VoiceBlue Enterprise

1.4. RF Radiation Safety Precautions

! It is prohibited to use any transmitters, including GSM

gateways, in areas where explosives are used, such as quarries.

! It is forbidden to use mobile phones and thus GSM gateways

too at petrol stations.

! A GSM gateway may affect sensitive life-saving devices in

medical centres. So it is prohibited to use mobile phones and
GSM gateways here.

! In general, any prohibition regarding mobile phones based on

RF energy radiation applies to GSM gateways.

! Where necessary, a GSM gateway may be installed at a safe

distance (in the neighbouring building, e.g.) and an Ethernet
cable may be carried from the GSM gateway to the original
building.

! Although GSM gateways are not intended for aeroplanes or

cars, all relevant prohibitions and regulations regarding mobile
phones apply to them here.

2.2. Brief Installation Guide

• Proper mounting – 2N VoiceBlue Enterprise is designed for

suspension on a vertical surface. Fit the holder included in the
delivery on a wall and hang the gateway on it. For details on
the prescribed working position and other recommendations
refer to Subsection 2.3.

• Cable connection – connect the gateway using a patch-cable

to the LAN (Local Area Network). For details on proper wiring
refer to Subsection 2.4.

• Antenna connection – connect an internal antenna or an

external antenna cable to the SMA antenna connector. Place
the external antenna on a place with a good GSM signal (refer
to Subsection 2.5).

• Gateway power supply – the delivery includes a mains

adapter. Plug in the adapter connector into the gateway and the
power adapter into a mains socket (≈230V/50Hz). The gateway

turns on immediately (see Subsection 2.6).

• SIM card insertion – SIM cards are inserted in holders on the

gateway top. To slide the drawer out of the gateway press the
yellow button on the drawer with a suitable tool (pin, pencil,
...), see Subsection 2.7.

• PC connection and initial configuration – a web browser is

used for gateway configuration in normal operation. If you
have not defined the IP address for the gateway, use the serial
cable included in the delivery (refer to Subsection 2.8) for
initial configuration of the basic parameters (see Section 3).

• Setting and monitoring – Having set the basic network

parameters (IP address, etc.), you can configure the VoIP
gateway using a standard web browser. Configuration options
and essential procedures shall be discussed in detail in
respective sections.

2-4 2N® VoiceBlue Enterprise

2.3. Proper Mounting

• The gateway is designed for mounting on a vertical surface.

For this purpose a wall mounting holder is available. Just fit the
holder with dowels and screws (fig. 3) to the wall and hang the
gateway as shown in fig. 4.

Fig. 3 – Gateway Holder Wall-Mounting

Fig. 4 – Gateway Holder-Hanging

• It is possible to operate the VoIP GSM gateway in another

working position (e.g. on a desk) for a short time only, for
example in servicing centres for quick testing purposes.

The allowed working temperature and relative humidity ranges

are included in Section 14.

Installation 2-5

• Exceeding the recommended operating temperature values

need not affect the gateway function immediately but may
result in more rapid ageing and lower reliability.

• The gateway is intended for indoor use. It may not be exposed

to rain, flowing water, condensed moisture, fog, or mist.

• The gateway may not be exposed to aggressive gas, acid

vapours, solvents, etc. or aggressive liquids, during cover
cleaning, for example.

• The GSM gateway is not designed for high-vibration

environments, e.g. means of transport, machine rooms, etc.

• Free space has to be left under and over the gateway for cables

and agitated air to remove operational heat.

• Install the gateway on a place with a good GSM signal.

• A misplacement of the GSM gateway or its antenna near

television, broadcasting or similar RF-sensitive devices may
exercise an adverse effect upon their function.

• Being a source of RF energy emission, the gateway antenna

should not be located close to human bodies. The hazard is
higher than with mobile telephones because the gateway is
usually used by many people and thus employed more often.

2-6 2N® VoiceBlue Enterprise

2.4. LAN Connection

2N VoiceBlue Enterprise is connected to the 10/100BASE-T
(Twisted Pair Ethernet) LAN using a standard straight (non­crossed) cable terminated with RJ-45 connectors like other types
of equipment (PC, VoIP terminals, etc.).

2.5. Antenna Connection

No matter if equipped with two or four GSM modules, the VoIP
gateway has just one SMA antenna connector, see fig. 6, to which
an external antenna cable is connected. This external antenna
should be installed vertically on a place with a good GSM signal.

Fig. 5 – LAN Connection

Fig. 6 – Antenna Connector Connection

Tighten the antenna connector gently with your hand, never use a
wrench!

Installation 2-7

2.6. Gateway Power Supply

• Be sure to use only the mains supply adapter that is included in

the GSM gateway delivery.

• Before plugging in the gateway, make sure that the mains

voltage value meets the data given on the mains adapter label.

• Furthermore, make sure that the antenna has been connected. If

you connect the gateway to the power supply without an
antenna, the GSM module transmitter might get damaged.

• Now plug the supply adapter into a mains socket and connect

the adapter connector to the gateway, see fig. 7. The status
indicators indicate the proper operation. For their meanings
refer to Subsection 2.9.

Fig. 7 – Supply Adapter Connection

2-8 2N® VoiceBlue Enterprise

2.7. SIM Card Insertion

To insert your SIM card in the gateway, press the yellow button on
the appropriate card drawer with a suitable tool to make the drawer
slide out a little. Remove the drawer, insert the SIM card and
replace the drawer. You can replace SIM cards even with your
gateway on.

2.8. PC Connection

You need direct interconnection of your 2N VoiceBlue Enterprise
gateway and PC especially when you do not know the gateway IP
address and thus cannot configure it using a web browser. In such
a case, connect the gateway directly to your PC serial port with the
cable enclosed and select the basic network parameters using your
console interface.

Fig. 8 – SIM Card Inserting Procedure

You can control the console interface with any terminal-emulating
program according to the VT-100 specification at least. The
Microsoft Windows OS, e.g., contains a communication tool
HyperTerminal, which can be used for this purpose.

By default, the gateway serial port communication parameters are
set at 115,200 bits per second, 8 data bits, no parity, 1 stop bit, no
flow control. Set the communication program on the PC side
identically.

Installation 2-9

2.9. Status Indicators

There is a panel with five LEDs on the gateway upper cover. The
Power indicator signals that the gateway as a whole is in
operation. The other LEDs, marked GSM 1 to GSM 4, indicate the
status of each GSM module.

Power Indicator

Basic diagnostic tests are performed automatically whenever the
gateway is connected to supply voltage. Each test step is signalled
by a specific colour combination of the LEDs. The testing process
is usually shorter than 0.5 sec and so it looks like a quick sequence
of LED flashes at first sight. If, however, a test step fails, the
indicator combination related to the failed test remains lighted.
This provides a convenient troubleshooting tool to the technical
support personnel.

After all hardware tests have been completed successfully, the
operating system kernel is loaded. During the process, all GSM
module indicators are off and the blue continuous Power light
blinks with the period of approximately 1 second.

When the operating system kernel has been loaded, the blue Power
indicator keeps shining continuously.

In exceptional cases, when a fatal failure of software occurs and
the gateway stops working, the Power indicator starts flashing
quickly. All you can do is disconnect the gateway from the power
supply for a few seconds and restart it.

2-10 2N® VoiceBlue Enterprise

GSM Indicators

The GSM 1 to GSM 4 indicators signal the status of the respective
GSM module. After connection to the power supply, the VoIP
gateway application starts within two minutes. During that time,
the installed GSM modules and SIM cards are detected. If a GSM
module or SIM card is not detected, the respective indicator
remains off.

If they are detected, the process of module and SIM card
initialisation is commenced. The respective indicator shines red
during the process. If the process is unsuccessful, the LED goes
off. If the indicator turns orange, it means that the module has not
logged-in to any GSM network.

If the LED is green, you can make calls and send SMS via the
respective module.

The respective module LED blinks green quickly during call
establishing. When the connection has been built successfully, the
indicator remains green during the whole call.

Administration 3-5

As soon as the requested information is entered, the respective
operation is executed. If the operation changes the parameter
settings, new values are displayed in the redrawn menu.

Some configuration parameters may have just one of two constant
values. By selecting such an item you immediately make its value
opposite to that preceding the selection. Typical examples are on
and off parameters. If their value is on, then it becomes off when
the item is selected and vice versa.

Some commands execute operations that have a serious impact on
the behaviour of the entire system (such as restart). Therefore, the
system usually "makes sure" before execution whether it is really
your intention.

Are you sure [y/n] :

If you give an answer other than "y" or "Y", the command will not
be executed.

To cancel the command execution and quit the prompt press the

key any time.

About Menus…

We shall discuss the serial console menus in detail in sections
devoted to gateway parameter settings. Below is a brief survey of
these menus only.

Main menu: Appears after the serial cable is connected to the
terminal. From the main menu you can get into the configuration
menu, change the administrator password, or display the help.

Configuration menu: Contains two submenus: network
configuration and serial console settings.

Network configuration: Used for setting the gateway IP address,
network mask, initial router, DNS addresses, network name and
domain.

Serial console configuration: Helps set the terminal type and
change the initial serial link parameters – transition rate, data and
stop bits, parity and flow control type.

3-6 2N® VoiceBlue Enterprise

DTR Signal Monitoring

The VoiceBlue Enterprise software monitors continuously the
Data Terminal Ready (DTR) signal. This signal is used for
detecting the presence or absence of terminal connection to the
serial console port.

When terminal disconnection is detected, the following operations
are performed:

• All initiated operations are cancelled.

• The main menu gets displayed.

If the connecting cable does not interconnect the DTR signal, you
cannot work with the serial console!

3.2.2. Telnet console access

This is a short description of new features added to the serial
console configuration. For the standard serial console
configuration capabilities refer to the 2N VoiceBlue Enterprise

There is also a possibility of using Telnet for 2N VoiceBlue
Enterprise configuration in addition to the standard serial console
configuration. Connect to your VoiceBlue via Telnet (type telnet
<your VoiceBlue IP address> in command line). If successful,
VoiceBlue will require an authentization from you. To log in, use
valid login and password of one of VoiceBlue’s users who is in
Administrators group. No user other than user from Administrators
group will be logged in. If login and password entered correctly,
you will be logged in.

Now you will see the window similar to the standard serial console
configuratoin window and you can work with it in the same way.
To log out Telnet configuration, get to the main menu and choose
Logout option (this option is not visible in the serial console
window).

There are two new menus added to the Configuration menu - menu
States and menu Command line. They allow you to control and
configure VoiceBlue devices, calls, lines and routes.
