2N - ISDN BRI GSM Enterprise Gateway
1.1. Purpose
•
The
2N - ISDN BRI GSM Enterprise gateway
helps
interconnect the ISDN and GSM networks. It can also be
applied in direct ISDN PBX
- GSM connections,
in combination with an ISDN telephone set, analog telephone
set or a coin-operated telephone connected through a terminal
adapter, etc.
•
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 - ISDN BRI GSM
Enterprise gateways
can send and receive short text
messages. This function along with other additional functions
enhances the utility value of the product.
•
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 USB and supply
cables, antenna and SIM card and set the ISDN and GSM
parameters.
1.2. How to Cut Telephone Costs
•
Once your
2N – ISDN BRI GSM Enterprise
gateway has
been connected to your ISDN PBX, all calls going out to
a mobile network are made directly.
This saves your PSTN -
mobile network call costs.
All mobile telephone calls of your
personnel in the field are cheaper too.
•
You are advised to use the
most advantageous rate of your
GSM provider
for your GSM gateway because all gateway
user call accounts are added up for billing purposes.
•
You can bar selected numbers or groups of numbers in your
gateway.
You shall pay nothing for the calls you have
barred.
