High Performance

■Hi/fn™ LZS® compression, which conforms to these IETF RFCs: The PPP Compression Control Protocol (RFC 1962) and PPP Stacker LZS Compression Protocol (RFC 1974).

■Multilink PPP (RFC 1990), which combines two PPP B channel calls to create a virtual, single 128 Kbps network connection.

■TollMizer, which places a single B channel or a Multilink PPP data call over a voice connection, saving you the additional charge for a data call.

Connectivity

■ISDN Basic Rate U interface.

■Built in four-port 10BASE-T, 10 Mbps Ethernet hub. Up to 25 users can be supported by connecting to an external eight port-hub.

■Two analog voice ports.

■Preferred Provider support which allows simultaneous connections to two different ISPs.

Routing

■IP Routing.

■Dynamic or static IP addresses supplied by the ISP (WAN side).

■WAN access for up to 25 local workstations on the LAN (10BASE-T).

■Dynamic Host Control Protocol (DHCP) server functionality on the LAN, which automatically assigns an IP address to a newly-attached computer on an IP network.

■Domain Name Service (DNS) server functionality for the LAN, which translates the common, alphanumeric name of a device to the numeric IP address of a device.

■Network Address Translation (NAT) between LAN and WAN, which allows multiple users on the LAN to share a WAN connection. Note that individual email accounts may still be maintained at the ISP.

■Multiplexing traffic from several computers to the same remote destination.
