You can connect the RoamAbout R1 to the Internet, or to a remote site, using its RJ-45
WAN port or RS-232 serial port. The RoamAbout R1 can also be connected directly to your
PC, or to a LAN (local area network), using any of the three Fast Ethernet LAN ports or
through the wireless interface. It can also function as a print server.
The RoamAbout R1 supports dial-on-demand for ISDN/PSTN service by automatically
connecting to the Internet when there are requests, and terminating the connection if no
further requests occur. This dual-port design also supports fail-over Internet access through
the secondary WAN port (i.e., the serial port can be used for primary or backup Internet
access).
