1.1 Product Description
2NVoiceBlue Next is a device that helps directly interconnect a SIP-supporting VoIP
network with GSM networks and can be used for direct connection with a telephone
set. The voice mode, i.e. outgoing and incoming calls, is the basic function of the
gateway. 2NVoiceBlue Next is equipped with all voice mode functions and provides
the highest user comfort. In addition to voice transmission, 2NVoiceBlue Next
enables you to send and receive text messages (SMS). No additional equipment (such
as an external phone) is needed for normal operation. You can use the web interface
or AT commands for all the gateway settings. The programmable parameters are set
in such a way that you can make calls the moment you connect the system to the
Ethernet, connect an antenna and insert the SIM card. 2NVoiceBlue Next can be
combined with the 2N Mobility Extension service (remote GSM extension) for up to 8
users1. 2NVoiceBlue Next also provides connection to the 2NSIM Star system2.

1.2 Safety Precautions
It is prohibited to use any transmitters, including the UMTS/GSM devices, in areas
where explosives are used, such as quarries.
It is prohibited to use the GSM gateways at petrol stations where mobile telephones
are also prohibited.
GSM phones may affect sensitive life-saving devices in medical centres. Therefore, it is
forbidden to use GSM/UMTS devices, including the GSM gateways, in such facilities.
In general, any prohibition regarding mobile phones based on RF energy radiation
applies to GSM/UMTS devices too.
If necessary, the GSM gateways may be installed at a safe distance from the
prohibited area and connected with the original place through an Ethernet cable.
Although GSM gateways are not intended for cars or aeroplanes, all relevant
prohibitions and regulations regarding mobile phones apply to them too.

SIM Card Placement (4-Channel Version)
Insert a SIM card into one of the four SIM holders on the 2NVoiceBlue Next front
making sure that the chip contacts are at the front bottom. The SIM holders are
equipped with the push&pull technology for facilitation.
Caution
Remember to set call forwarding, call barring, preferential network(s),
SMS centre and similar provider and SIM card services in your mobile
phone before inserting the SIM card in 2NVoiceBlue Next.
If two SIM cards are used, both of them must have an identical PIN,or
PIN request disable must be selected.
Disconnect 2NVoiceBlue Next from the power supply before inserting
the SIM cards!
Licences
2NVoiceBlue Next may contain time-limited software licences (SIP signalling,
Mobility Extension, e.g.) that render services for limited hours only. Every gateway
restart adds one hour to the internal licence counter. To check the current licence
status, use the web interface of the gateway (refer to Subs. 3.4, p. 45), or the AT
interface of the Telnet protocol (refer to S. 4, p. 67).

Before You Start

Caution
A GSM gateway with an expired licence cannot process any incoming
and/or outgoing calls! To avoid this, ask your dealer for licence
prolongation or an unlimited licence!
GSM/UMTS Network Restriction
Some 2NVoiceBlue Next types may be restricted to certain GSM/UMTS networks
only. If so, the red indicator at the given GSM/UMTS module is on and the netw-err
cause is detected. Contact your dealer please for more information.
Tip
Contact your dealer please for more information.
Potential GSM/UMTS Troubles
All 2N GSM gateways work reliably under a long-time full load. The following problems
may be caused by GSM/UMTS networks:
GSM/UMTS module(s) cannot log in, log in slowly, or log out occasionally. This
problem may be caused by any of the following situations:
The GSM/UMTS signal is low. The minimum signal level should be
approximately -80dBm. If lower, change the antenna position or type!
The GSM/UMTS cell (BTS) to which the GSM/UMTS modules are trying to
log in is overloaded. Change the antenna position or reduce the count of
the logged-in GSM/UMTS modules.
One of the GSM/UMTS modules is permanently logged-out or fails to make
outgoing calls:
The problem indicates a GSM/UMTS network overload on the installation
site. To eliminate the problem, set the Relax delay parameter to 2
seconds (refer to the GSM Basic Parameters subsection, p. 39). If the
GSM module fails to log in or rejects to make outgoing GSM calls even
after the gateway restart, consult your GSM provider for your SIM
card/GSM module availability.
The manufacturer shall not be held liable for any SIM card or provider service

SIM Card Inserting/Removing
For the correct handling of SIM cards refer to the SIM Card Placement subsection on
p. 16.
Caution
Make sure that the GSM gateway is off before inserting and removing SIM
cards to avoid the GSM/UMTS module damage.
Installation Conditions
The following installation conditions have to be met for proper installation:
2NVoiceBlue Next is to be installed on a site with enough free space.
2NVoiceBlue Next 2NVoiceBlue Next can be mounted on a vertical surface
(2-channel version), or on a horizontal surface or into a system rack (4-
channel version). It is possible to operate 2NVoiceBlue Next in another
working position too, e.g. on a desk, for a short time for servicing and testing
purposes, for example.
Any excess of the allowed working temperature may not affect the 2N
VoiceBlue function immediately but may result in faster ageing and lower
reliability. For the allowed working temperature and humidity ranges refer to
S. 5, p. 85.
2NVoiceBlue Next is not designed for high-vibration environments such as
means of transport, machine rooms, and similar.
2NVoiceBlue Next is not designed for dusty environments or places exposed
to high humidity and temperature changes.
2NVoiceBlue Next may not be exposed to aggressive gases, acid and solvent
vapours, and so on.
2NVoiceBlue Next is intended for indoor use. It may not be exposed to rain,
flowing water, condensing moisture, fog, and so on.
2NVoiceBlue Next may never be exposed to direct sunshine or placed close
to heat sources (radiators).
A sufficient clearance must be kept over and under 2NVoiceBlue Next for
cabling and air flow to carry off the heat.
A sufficient GSM/UMTS signal intensity has to be provided for 2NVoiceBlue
Next.
An adequate capacity of the GSM/UMTS network has to be ensured (no BTS
overload). Remember that multiple GSM gateways used in one location may
overload the base transceiver station (BTS) you are currently logged in to.
This may lead to a permanent or occasional rejection of GSM/UMTS calls!
