DW4020 Router
The DW4020 is a stand-alone device that can be connected to the DIRECWAY satellite network
to form an Internet access gateway. The DW4020, whose software is stored in non-volatile memory, performs all of the hosting
functions that a PC performs in the current DW4000 USBPC configuration. That is, the DW4020 downloads code to the satellite modem,
performs PEP and decompression, and monitors and controls the operation of the satellite modem. In addition, the DW4020
supports configuration and status monitoring through an internal Web server that communicates with a standard Web browser running on a host on the LAN.
