modem (To configure the Terminal as a modem you
should use standard Windows modem configuration
procedure).
There are two data connection methods available:
GPRS DATA - With GPRS you are not charged
for the connection time but for your bandwidth
usage (amount of data tranferred). GPRS allows
you to make only outgoing calls, such as an internet
connection. See Appendices A & B for instructions
on how so set up a GPRS connection on your PC.
GPRS services must be registered with your
network operator in order to function.
GSM DATA - With GSM Data you are charged for
your time online. GSM allows both incoming and
outgoing calls. GSM Data connections are made the
same way as with a standard modem with your PC
configured for a fixed-line connection.
Since the GSM Terminal supports auto-bauding up
to 57,600 bps, make sure that maximum speed of
the PC modem is set to 57,600.
Also, you may need to use the following
initialization string, “AT+CSNS=4”, to accept calls
coming from outside of GSM network using single
numbering scheme.
Your SIM card must support GSM Data in
order to use this method.
Data Bearer Type Selection
The data bearer type selection dialing sequence
selects the bearer service with a data rate and a
service type to be used when making outgoing data
calls. Service type selection also applies to mobile
terminated (incoming) calls if the Single Numbering
Scheme is used. For incoming calls, bearer type
selection should match the network proposed service
type. If the unit is set to Transparent only and
the network proposes Non-Transparent only or vice
versa, then the call is released.
The default setting is Data Circuit Asynchronous
with Autobauding and Non-transparent only. This
dialing sequence updates the default bearer type
values stored in the GSM Terminal and the selected
