■V.42/MNP 2-4 error control and V.42 bis/MNP 5 data compression

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

Connectivity

■Two 56K integrated analog modems

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

■Two pass-through, analog voice ports for connecting up to two external analog devices

■Virtual Private Network (VPN) pass-through capability using client software

Virtual FAX Modem

■Allows Windows users on the LAN to access one or both modems as if directly connected through an RS-232 serial (COM) port.

■Creates support for applications requiring a dedicated modem, such as Class 2.0 fax applications, and online services.

Routing

■IP Routing

■Dynamic or static IP addresses supplied by your service provider (WAN side)

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

■Domain Name Service (DNS) server functionality for the LAN, which translates the common, alphanumeric name of a device (for example, “www.3com.com”) to its numeric IP address
