The RJ-45 port on the faceplate of the 3G EHWIC provides access to the debug port on the Sierra 
Wireless modem. By connecting an industry-standard diagnostic tool like Qualcomm CAIT/QXDM or 
Spirent UDM to this port, you can perform radio-level diagnostics and traffic monitoring on the modem. 

Use the following test commands to enable/disable the DM port:

router# test cell-hwic 0/1/0 dm-port local {on | off | speed}

router# test cell-hwic 0/1/0 dm-port remote {on | off}

For example, to enable the DM port, use one of these commands:

router# test cell-hwic 0/1/0 dm-port local on

router# test cell-hwic 0/1/0 dm-port remote on

The cable used to connect the PC/Laptop running the diagnostic tool is the standard Cisco router console 
cable (RJ-45 to DB-9). 

To enable test commands, you must enter the service internal command in global configuration mode.
