authentication on dial-up lines. RADIUS support allows you to use an external server for
unlimited number of users and the ease of centralized management.
PAP and CHAP Security
The Prestige 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 Support
DHCP (Dynamic Host Configuration Protocol) allows the workstations on your LAN to obtain
the configuration from the Prestige.
Call Control
Your Prestige provides budget management for outgoing calls and maintains a blacklist for
unreachable phone numbers in order to save you the expense of unnecessary charges.

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