Accepts 10-30v DC Input
Modem can connect to an ISP or to another 56k LAN Modem/Dual 56k LAN Modem to extend the LAN. The routers have to be set as Site A, B, or C and can't be the same. Site A gets 192.168.1.0, B is 192.168.2.0, C is 192.168.3.0.
You can connect a client remotely but the client is put onto their own subnet with no access to network resources, only for administration.
Default IP is 192.168.1.1
