7.3. FAX Transmission - PC-FAX
SmartGate allows fax transmissions from your PC. However, do not confuse the PC-
Fax service with a standard fax service – no fax machine can be connected to the
telephone line! But the PC-Fax can establish connection with a standard fax machine
and transmit documents.
To enable the PC-Fax service, install the faxmodem driver from the SmartGate CD-
ROM first. Further you need the PC-Fax software, which is not included. In general, any
program designed for SIEMENS data modules (SIEMENS MC45/46 or MC55/56) can
work with SmartGate. The WinFax program from Symantec has been successfully
tested for this purpose, you can use the fax service included in Windows XP as well.
7.4. CSD or High-Speed GPRS Data Connection to Internet
To connect to the Internet, install the faxmodem driver from the SmartGate CD-ROM
first. Another possibility is to use the GSM provider’s installation wizard in case it
supports the SIEMENS GSM module installed in SmartGate (SIEMENS MC45/46 or
MC55/56).
The installation wizard usually configures the telephone connection of the network
too. If you use manual installation, you have set it properly. Ask you GSM provider for
Internet connection instructions because they can be different for each provider
(especially the telephone number to be dialed, DNS, etc.). It is necessary, for example,
to set the APN in modem extra settings in the GPRS mode:
Example: at+cgdcont=1,"IP","internet.t-mobile.cz"
Caution! GSM providers mostly specify the *99# number to be dialed for GPRS
connection in their instructions. SIEMENS GSM modules require the *99***1# format.
7.4.1. CSD or GPRS Data Connection?
The maximum CSD transmission rate is 14400 bps. GSM connection is reserved for
the whole time of connection and calls are charged according to the connection time.
The CSD mode can provide data connection of two PCs.
SmartGate is equipped with GSM modules providing GPRS class 10 (4+2 timeslots),
which means that it is able to transmit data into a PC at the rate of 85600 bps and at
half the rate towards the GSM network. The GPRS cannot be used for connection of
two PCs. It can only provide connection with an APN – e.g. the Internet. Most GSM
providers charge GPRS connections according to the volume of data transmitted or by a
lump sum and so the GPRS is suitable for long-time connection with occasional data
transmissions.
7.5. SMS Sending and Receiving
It is possible to send and receive SMS units using appropriate AT commands. There
are a number of PC programs that are based on this principle. Install SW designed for
SIEMENS GSM modules (SIEMENS mobile telephone SW can also be used). You can
send and receive SMS even during SmartGate voice calls.
