Accepts 10-30v DC Input
Can make simultaneous connections through both modems - 2 different ISPs, 1 to an ISP, 1 to a remote LAN, 2 different remote LANs, etc..
Can make multilink connections - both to an ISP or to another Dual 56k LAN Modem
You can remotely connect a client to one of the modems, but it puts the client on their own subnet with no access to network resources, only good for administration
