1.3 Features of Prestige 128MH

Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost any user.

Ease of Installation

Your Prestige is quick and easy to install. Physically, it resembles an external modem except for
the fact that it is a router and uses an Ethernet cable to connect to the host network.

Multiple WAN Ports

Your Prestige 128MH has three WAN ports (WAN-1,2,3). WAN port 1 can be connected to a dial­up/leased line modem or to an ISDN TA (Terminal Adapter). WAN port 2,3 are internally
connected to two high-speed 56K modems that support dial-up configurations.

Leased Line/Dial Back-Up Support

Your Prestige 128MH supports a leased line connection to its serial port WAN port 1. The
Prestige can also support dial back-up function for the leased line connection.

Multiple Networking Protocol Support

The Prestige 128MH is a multi-protocol router that supports TCP/IP, Novell IPX, and Transparent
Bridging.

Dial-On-Demand

The Dial-On-Demand feature allows the Prestige 128MH 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
128MH dynamically allocates bandwidth between the WAN ports, increasing or decreasing

speeds as needed to allow for greater efficiency in data transfer.

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.

Data Compression

Your Prestige incorporates Stac data compression and CCP (Compression Control Protocol).

Networking Compatibility

Your Prestige is compatible with remote access products from other manufacturers such as
Ascend, Cisco, and 3Com. Furthermore, it supports Microsoft Windows 95 and Windows NT
remote access capability.

1.4 Applications for Prestige 128MH

The Prestige 128MH offers complete solutions for your WAN applications such as Corporate
Internet Access, Internet Single User Account, LAN-to-LAN Connections, Telecommuting and
Remote Node Access.

Internet Access

The Prestige 128MH is the ideal high-speed Internet Access solution for the corporate and branch
offices. Your Prestige 128MH supports the TCP/IP protocol, which is the language used for the
Internet. It is also compatible with access servers manufactured by major vendors such as Cisco
and Ascend. A typical Internet Access application is shown in Figure 1-3.

Internet Single User Account

For a small office environment, your Prestige offers a Single User Internet Account from an ISP
(Internet Service Provider). This allows multiple users on the LAN (Local Area Network) to
access the Internet concurrently for the cost of a single user. Single User Account address
mapping can also be used for LAN to LAN connection.

PSTN Network

Multiprotocol/Multiport LAN-to-LAN Connection

Your Prestige can dial to or answer calls from another remote access router connected to a
different network. The Prestige supports TCP/IP, Novell IPX, and has the capability to bridge any
Ethernet protocol. Your Prestige can also bundle several WAN ports in one LAN-to-LAN
connection for greater bandwidth. A typical LAN-to-LAN application for your Prestige 128MH is
to connect the Corporate Office LAN of your company with the Branch Office, as shown in
Figure 1-4.

Dial-On-Demand

Also, with the automatic Dial-On-Demand, your Prestige 128MH makes a connection only when
data is transferred between the Corporate LAN and the Branch Office. Dial-On-Demand
minimizes connection charges and user intervention.

Telecommuting Server / Remote Access

Your Prestige allows Remote Dial-in Users to dial-in and gain access to your LAN. This feature
enables users that have workstations with remote access capabilities (for example, Windows 95),
to dial in using a modem or an ISDN terminal adapter (TA) to access the network resources
without physically being in the office. Figure 1-5 shows how a remote user or a telecommuter can
connect to its corporate office via a modem or ISDN TA and the PSTN/ISDN network.

Prestige 128MH allows up to three simultaneous remote-access connections or one PPP/MP
bundled connection. PAP or CHAP password checking may be used to control the access from
remote users to the corporate LAN. Also, call-back can be used to authenticate connections from
remote users
