1-4 Getting to Know Your Prestige
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.
1.3 Internet Access With the Prestige
These sections provide example applications for your Prestige.
1.3.1 Internet Access
The Prestige is the ideal high-speed Internet access solution. Your router supports the TCP/IP protocol,
which the Internet uses exclusively. It is also compatible with access servers manufactured by major vendors
such as Cisco and Ascend. A typical Internet Access application is shown next.
