Prestige 128MH PSTN Router/Hub
1-6 Chapter 1 Getting to Know Your Router/Hub
By using the PPP/MP (Point-to-Point Protocol/Multilink Protocol), your Prestige 128MH can
bundle three WAN ports connected to three different internal and external modems in order to use
the maximum available bandwidth. The Prestige 128MH 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 128MH 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.
DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows you to dynamically and automatically
assign IP address settings to hosts on your network.
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.
