•2 Telit USB Modem ports
•1 Telit HS-USB WWAN
•1 Telit Serial Diagnostic Interface
The screenshot below reports an example of the port composition listed on Windows 10
Device Manager.
USB Modem ports are ACM devices and can be used as AT Command interface.
Telit HS-USB WWAN is an RMNET adapter that can be used with Linux ModemManager and
NetworkManager.
On Windows 10 WWAN Adapter should be automatically loaded as Cellular Connection in
Network & Internet settings (see image below).

Telit Serial Diagnostic Interface is used for debugging purposes and firmware upgrades.
Warning on Windows Cellular connection
When the module is recognized as a Cellular device, Windows uses the WWAN interface to
set up an internet connection (NCSI). This could lead to connectivity issues using the module
AT interface: registration to the network, APN management, socket creation, and data
exchange, PSM, and eDRX functionalities can be affected.
If you do not need your PC is connected via the WWAN interface, we strongly suggest
disabling it. Go to: Control Panel ►Network and Sharing Center ►change Adapter settings
►right-click on Cellular connection ►disable.

ESD PROTECTION
Here below is a brief overview of the 4G (CAT M1, NB IoT) and 2G (GPRS) registration
process, IP stack setup, and related commands.
4G registration (CAT-M1, NB-IoT) and IP stack setup: the module performs Attach and EPS
Bearer activation automatically. When the procedure ends an IP address is assigned by the
network to the module. AT+CEREG can be used to check the EPS network registration status.
AT+CGCONTRDP can be used to check the EPS bearer parameters. AT#SGACT command
has to be used to enable the internal IP stack and IPEasy command set.
2G registration and IP stack setup: the module performs GPRS Attach automatically. You can
check the status of registration using AT+CREG and AT+CGREG commands. To get IP
connectivity the user has to activate a PDP context. In this scenario, AT#SGACT command
performs PDP context activation and IP internal stack enabling. After this step, the module
has an IP address and the IPEasy command set can be used. AT+CGCONTRDP can be used to
check the PDP context parameters.
To get IP connectivity, for all access technology, a specific APN configuration is required. We
suggest carefully check with the Network Provider what’s the proper APN configuration to be
used (context ID, APN name). APN configuration can be set through the AT+CGDCONT
command.
CAT-M1 / NB-IoT Registration AT script example
The module is turned on, APN on context 1 is required by MNO for registration and data
traffic
AT+CEREG?
+CEREG: 0,2
OK
AT+CGDCONT=1,"IP","nbiot.tids.tim.it"
OK
A new attach is needed to use the new APN. A way to do this is to turn the radio off and on
using AT+CFUN
AT+CFUN=4
OK
AT+CEREG?
+CEREG: 0,0
OK
AT+CFUN=1
OK
AT+CEREG?
+CEREG: 0,0
OK
AT+CEREG?
+CEREG: 0,2
