Getting to Know Your Bridge/Router
Dial-On-Demand
The Dial-On-Demand feature allows the Prestige 153/153X to automatically place a call to a
remote node whenever there the traffic coming from any workstation on the LAN is directed to
that particular remote site.
Bandwidth-On-Demand
The Bandwidth-On-Demand feature provides flexible bandwidth when needed. The Prestige
153/153X dynamically allocates bandwidth between the WAN ports, increasing or decreasing
speeds as needed to allow for greater efficiency in data transfer.
By using the PPP/MP (Point-to-Point Protocol/Multilink Protocol), your Prestige 153/153X can
bundle three WAN ports connected to three different modems or ISDN TAs in order to use the
maximum available bandwidth. The Prestige 153/153X supports BAP (Bandwidth Allocation
Protocol) and BACP (Bandwidth Allocation Control Protocol) to manage the number of links in
multilink bundle.
Full Network Management
Your Prestige 153/153X supports SNMP (Simple Network Management Protocol) and allows
menu-driven network management via an RS-232 or Telnet connection. Your Prestige is also
equipped with a Call Detail Record to help analyze and manage your telephone bill.
RADIUS
The RADIUS (Remote Authentication Dial-In User Service) feature allows you to use an external
and central Unix-based server to support thousands of users.
PAP and CHAP Security
The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). With PAP authentication enabled, the user sends the name and password
in plain text. Generally, CHAP authentication is more secure since the password is scrambled
prior to transmission. However, PAP is readily available on more platforms.
