1 Introduction
HC15 is the first Siemens wireless module to offer UMTS and GSM capability on the same
device. The benefit is that the HC15 includes HSDPA capability in a UMTS network and also
all common mobile connectivity features like voice, short messages, GPRS and EGPRS.
The HC15 modules need to connect to an adequate host device, such as the Evaluation
Board DSB75. Designed to help application manufacturers and system integrators to test
and develop their HC15 host application, the DSB75 provides all interfaces and peripherals
needed to run the HC15.
The purpose of this document is to guide you through the process of connecting the
hardware, installing the software on a Windows XP system, and, last but not least, making
the first data transmission via UMTS and HSDPA.

3 Using the HC15 Module
The following examples show the basic steps required to register to the network, to select
UMTS mode or GSM mode and to attach to HSDPA or GPRS.
The examples are based on a UICC card provisioned by the German network operator T-
Mobile. The used UICC card is capable of UMTS and GSM and enables the subscriber to
switch back and forth between both networks.
3.1 AT Command Interpreter
AT commands can be entered on two interfaces of the HC15 module:
•Siemens HSDPA USB Com Port
•Siemens HSDPA USB Modem
Yet, we recommend that the Siemens HSDPA USB Com Port be used for controlling the
HC15 module, eg. for entering AT commands and receiving URCs, while the Siemens
HSDPA USB Modem is mainly intended for use as a modem. For greater detail refer to [1],
especially the chapters “AT Command Interpreter” and “Unsolicited Result Code
Presentation”.
As described in Chapter 2.5, each interface is assigned a virtual COM port of its own, which
enables accessing the interface from the host application or, accordingly, the dial-up
connection. To easily identify both interfaces you can use the AT^SQPORT command:
AT^SQPORT
Application
OK
On the AT command interface, the Siemens
HSDPA USB Com Port is referred to as
“Application”.
AT^SQPORT
Modem
OK
On the AT command interface, the Siemens
HSDPA USB Modem is referred to as
“Modem”.
If you need to operate the HC15 from both interfaces at a time, bear in mind that both are
handled by the same AT command interpreter. As a result, AT commands entered on both
interfaces are not executed in parallel but sequentially, one after the other. So, an AT
command issued on one interface will be buffered on this interface to be executed after the
other interface has completed processing earlier AT command(s). The buffered command
string is not echoed, but will be indicated when executed.

3.2 Switching on the HC15
The HC15 can be started by pressing the IGT key of the DSB75. Please wait approximately
2 seconds before using the module, for example before entering AT commands.
Disconnecting and plugging the USB cable during operation is not supported.
3.3 Switching off the HC15
To shut down the HC15 module, enter the AT^SMSO command. This enables the ME to
save all data and perform an orderly shutdown.
AT^SMSO
OK
The ME switches off.
The HC15 module can also be switched off by using the IGT line as described in [1] (see
AT^SCFG) and [1] (see section “Configuring the IGT Line for Use as ON/OFF Switch”).
3.4 Registering to the Network
Make sure to operate the HC15 always with the UICC card inserted in the DSB75 card
reader and a valid SIM PIN entered. This is because most AT commands require SIM PIN
authentication.
Write command: AT+CPIN=<pin>[, <new pin>]
at+cpin?
+CPIN: SIM PIN
OK
at+cpin=1234
OK
at+cpin?
+CPIN: READY
OK

3.5 Selecting UMTS or GSM
The GSM 07.07 operator selection command AT+COPS has been enhanced to enable the
subscriber to select whether to use UMTS or GSM. You can quickly switch back and forth
between both network types while the ME remains registered.
Write command: AT+COPS=<mode>[, <format>[, <oper>[, <act>]]]
The parameter <act> (access technology) can take the values listed below. The parameter is
stored non-volatile.
0 GSM network
2 UMTS network
Note: By factory default, an automatic network selection mode is set which enables the ME
to select either UMTS or GSM, depending on the network coverage. This automatic mode
remains enabled until you explicitly set either UMTS or GSM using the <act> parameter of
AT+COPS. Setting the <act> parameter forces the ME to select either UMTS only or
accordingly, GSM only. If the specified network is not available, the network registration will
be disabled.
at+cops?
+COPS: 0,0,"T-Mobile D",2
OK
Querying the current network mode.
The ME is registered to the German
operator T-Mobile and uses UMTS.
at+cops=0,,,0 #(or at+cops=,,,0)
OK

3.10 HSDPA or GPRS Data Transfer
HC15 offers two alternatives to access the GPRS or HSDPA networks:
•The Siemens Connection Manager provided for the Siemens Wireless Ethernet Adapter
See chapter 3.10.1.
•A dial-up network connection via the installed Siemens HSDPA Modem as described in
chapter 3.10.2.
In either case the ME must be registered to the network. So, before trying to connect to the
data services ensure that SIM PIN authentication was done from the host application. To
take advantage of HSDPA make sure that the <act> parameter of AT+COPS equals “2”. For
GPRS the parameter shall be “0”. It is recommended to configure these settings on the
Siemens HSDPA USB Com Port.
3.10.1 HSDPA or GPRS Data Transfer via Siemens Wireless
Ethernet Adapter
The easiest way is using the Siemens Connection Manager installed along with the HC15
driver package.
•To open the tool in Windows XP, click Start, point to Programs, select Siemens, select
HSDPA USB Modem and click Connection Manager.
•Use the Select Device listbox to
choose the Siemens Wireless
Ethernet Adapter. When opened
the first time or after disabling the
adapter, the listbox may be
empty.
•Check the APN Name box and
enter the APN (Access Point
Name) of your service provider.
•If necessary, check the
Authentication Preference box
and select the type of
authentication protocol.
Otherwise, PAP and CHAP apply
by default. Username and
password are also provider
dependent.
•Press the Connect button to set
up a connection. Then simply
open your Internet browser. The
box on the rightmost bottom
represents the signal strength.
•To close the connection press the
Disconnect button (available when connected).
The Auto Connect check box on the leftmost bottom can be activated if you want the
Siemens Wireless Ethernet Adapter to automatically connect to the network each time you
restart the HC15. This option can be used particularly with a flat rate subscription. In this
case, take care that the SIM PIN authentication is also done automatically.
