∙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.
