MP880W Modem User Guide
The MP modem VSPs are available on both USB and Ethernet interfaces. For information on enabling a virtual serial port, see the MP 3G Modems AT Command Reference manual (document #2130810).
VPN support for RNAP
This feature allows for the exchange of Remote Network Access Protocol (RNAP1) data between the MP modem and a remote server accessible only through a Virtual Private Network (VPN) connection. When using this feature, you must have 3G Watcher running on the computer.
The MP modem sends RNAP data over Ethernet or USB to 3G Watcher on the computer. 3G Watcher places the RNAP data in a User Datagram Protocol/Internet Protocol (UDP/IP) packet and sends it over the VPN connection to the server. When 3G Watcher receives a UDP/IP packet containing RNAP data over the VPN connection, it disassembles the packet and sends the RNAP data to the MP modem.
You can enable this option using 3G Watcher software or AT commands. See the 3G Watcher online help and the MP 3G Modems AT Command Reference manual (document #2130810) for details.
Software
The MP modem comes with the following software:
•3G Watcher, the software for the MP modem which allows you to manage and monitor your connections.
•The driver that forms the interface between the MP modem and your Windows operating system.
•The firmware that is stored in non‐volatile memory.
The MP modem has an embedded radio module (a
Mini Card 8775), also made by Sierra Wireless, Inc. There are two firmware programs on the MP
The firmware was loaded into the radio module and con‐ troller board when the MP modem was assembled. As new
1.RNAP is a Sierra Wireless proprietary protocol that encapsu- lates the MTP data that is sent to and from the MP modem. It ensures that both the MP modem and remote host recognize the data packets. See The Monitoring and Tracking Protocol Guide on page 18.
