Prestige 153/153X WAN Bridge/Routers
1-2 Getting to Know Your Bridge/Router
• Multiple Protocol Support
♦ TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.
♦ Novel IPX (Internetwork Packet eXchange) protocol.
♦ Transparently bridging for network layers that the Prestige does not route.
♦ PPP (Point-to-Point Protocol) link layer protocol.
♦ SUA™ (Single User Account) for NAT (Network Address Translation).
• Dial-On-Demand
The Dial-On-Demand feature allows the Prestige to automatically place a call to a remote
gateway based on the triggering packet’s destination without user intervention.
• PPP Multilink Support
The Prestige can bundle multiple links in a single connection using PPP/MP (Point-to-Point
Protocol/Multilink Protocol). The number of links can be statically configured or dynamically
managed based on traffic demand.
• Bandwidth-On-Demand
The Prestige 153/153X dynamically allocates bandwidth by dialing and dropping connections
according to traffic demand.
• Full Network Management
Your Prestige 153/153X supports SNMP (Simple Network Management Protocol) and allows
menu-driven network management via the console port or a telnet connection. Your Prestige is
also equipped with a Call Detail Record to help to analyze and manage your telephone bill.
• RADIUS Support
RADIUS (Remote Authentication Dial-In User Service) is the most popular protocol for user
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.
