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.

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.
3.10.1HSDPA 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.
