Prestige 202H User’s Guide

PAP and CHAP Security

The router supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol). CHAP is more secure than PAP; however, PAP is readily available on more platforms.

DHCP (Dynamic Host Configuration Protocol)

DHCP (Dynamic Host Configuration Protocol) allows the individual client computers to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS servers to all systems that support the DHCP client. The Prestige can also act as a surrogate DHCP server (DHCP Relay) where it relays IP address assignment from another DHCP server to the clients.

Call Control

Your router provides budget management for outgoing calls and maintains a blacklist for unreachable phone numbers in order to save you the expense of unnecessary charges.

Data Compression

Your router incorporates Stac data compression to speed up data transfer. Stac is the de facto standard of data compression over PPP links.

Networking Compatibility

Your router is compatible with remote access products from other manufacturers such as Ascend, Cisco, and 3Com. Furthermore, it supports Microsoft Windows 95 and Windows NT remote access capability.

Upgrade Firmware via LAN

In addition to the direct console port connection, the router supports the up/downloading of firmware and configuration file using TFTP (Trivial File Transfer Protocol) over the LAN. Even though TFTP should work over the WAN as well, it is not recommended because of potential data corruption problems.
