Getting To Know Your Prestige 1-3
PAP and CHAP Security
The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure since the password is scrambled prior to transmission.
However, PAP is readily available on more platforms.
Filters
The Prestige's packet filtering functions allow added network security and management.
Reset Button
The Prestige comes with a reset button built into the rear panel. Use this button to restore the factory default
password to 1234, IP address to 192.168.1.1, subnet mask to 255.255.255.0 and DHCP server enabled with a
pool of 32 IP addressed starting at 192.168.1.33.
1.3 Applications for the Prestige
Here are some example uses for which the Prestige is well suited.
1.3.1 Internet Access
The Prestige is the ideal high-speed Internet access solution. Your Prestige supports the TCP/IP protocol,
which the Internet uses exclusively. It is compatible with all major ADSL DSLAM providers. A DSLAM is
a rack of ADSL line cards with data multiplexed into a backbone network interface/connection (e.g., T1,
OC3, DS3, ATM or Frame Relay). Think of it as the equivalent of a modem rack for ADSL. A typical
Internet Access application is shown next.
