1.1 Product Description
The GSM gateway provides direct interconnection of the2N Enterprise / BRI Lite
®
ISDN with GSM networks. It can also be used for direct interconnection of an ISDN PBX
with a GSM network, ISDN telephone set and, via a terminal adapter, with an analogue
apparatus or coin machine. The voice mode, i.e. outgoing and incoming calls, is the
basic function of the gateway. Moreover, the BRI gateway provides connection to the
VoIP–SIP networks. The gateway is equipped with all functions necessary for this mode
and is very user–friendly. In addition, allows you to 2N BRI Enterprise / BRI Lite
®
send and receive SMS messages. No additional devices (an external telephone, e.g.)
are required for normal operation. All gateway parameters can be set using a
configuration program (on an enclosed CD), or using the AT commands. Programmable
parameters are pre–set to make it possible to make calls as soon as the supply cable,
antenna a SIM cards are connected.
2N BRI Enterprise / 2N BRI Lite Differences
® ®
The and gateways are based on one and the same2N BRI Enterprise
®2N BRI Lite ®
type of hardware and apply identical firmware and control (configuration) software. The
only difference lies in the count of BRI ISDN interfaces:
Interface 2N®BRI Lite 2N®BRI Enterprise
BRI ISDN 1 (NT/TE) 2 (1 TE ; 1 NT)
Ethernet YES* YES*
*The VoIP–SIP support depends on Part No. (subject to licence).
Telephone Cost Cuts
Having connected to your ISDN PBX, you can2N BRI Enterprise / BRI Lite
®
make calls to the mobile network directly. This saves your PSTN – GSM
.connection costs
You do not pay for barred calls. You can set groups of barred numbers in the
gateway.
A flexible setting of the Least Cost Router helps you call GSM numbers at
.minimum operational costs
You can route calls to alternative providers' networks via the VoIP/SIP interface.
As all gateway user calls are added up for billing purposes, you are
advised to use the most advantageous tariff offered by your provider.

DialThru (2N BRI Enterprise)
®
The difference between and lies in the DialThru2N BRI Enterprise
®2N BRI Lite ®
functionality. DialThru enables the gateway to be connected between the PBX and the
voice service provider line, i.e. PSTN. The GSM gateway in the DialThru mode routes,
based on the LCR, calls into the PSTN or GSM/UMTS networks.
Refer to the figure below for a schematic diagram of the connecti2N BRI Enterprise
®
on.

82N TELEKOMUNIKACE a.s., www.2n.cz
®
The gateway works as a dial–through router (using both the TE and NT ports in the
DialThru
mode) for calls to a mobile network, and a monitoring system, which, with the
appropriate licence, sends SMS to the provider (in the case of line unavailability, e.g.).
The GSM gateway contains just one ISDN BRI port and thus cannot2N BRI Lite
®
work in the DialThru mode. It can be connected to a PBX on a trunk line or extension
and route calls to the GSM/UMTS networks only – see the figure below.

1.2 Safety Precautions
It is prohibited to use any transmitters, including the GSM/UMTS gateways, in areas
where explosives are used, such as quarries.
It is prohibited to use the GSM gateways at petrol2N BRI Enterprise / BRI Lite
®
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.

Potential GSM/UMTS Troubles
All gateways work reliably under a long–time full load. The following2N GSM
®
problems may be caused by GSM/UMTS networks:
The 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 . If lower, change the antenna position or type!–80dBm
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 parameter to Relax delay 2
. If the GSM module fails to log in or rejects to make outgoingseconds

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
unavailability in the case of a breach of the provider's SIM terms and conditions for the
SIM card use.

2.2 Brief Installation Guide
Installation Conditions
The following installation conditions have to be met for a proper installation:
2N BRI Enterprise / BRI Lite
® is to be installed on a site with enough free
space.
2N BRI Enterprise / BRI Lite
® is to be mounted on a suitable vertical surface.
For this purpose, a hanger is included in the gateway delivery, which is fitted to
the wall using dowels and screws and used for gateway hanging.
It is possible to operate the gateway 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 BRI
®
function immediately but may result in faster ageing andEnterprise / BRI Lite
lower reliability. For the allowed working temperature and humidity ranges refer
to .S. 7
2N BRI Enterprise / BRI Lite
® is not designed for high–vibration
environments such as means of transport, machine rooms, and similar.
2N BRI Enterprise / BRI Lite

places exposed to high humidity and temperature changes.
2N BRI Enterprise / BRI Lite
® may not be exposed to aggressive gases, acid
and solvent vapours (during cover cleaning, e.g.).
2N BRI Enterprise / BRI Lite
® is intended for indoor use. It may not be
exposed to rain, flowing water, condensing moisture, fog, and so on.
2N BRI Enterprise / BRI Lite

antenna should not occur in the close vicinity of the human body. The healthLite
hazard is higher than with mobile phones as, generally, gateways shared by
multiple users show a very high traffic.
It is recommended that the power supply adapter should be connected to a
network with a UPS back–up and due overvoltage protection.
SIM Card Inserting/Removing
Insert the SIM card in the bottom as shown in the2N BRI Enterprise / BRI Lite
