Prestige 153/153X WAN Bridge/Routers

Chapter 1

Getting to Know Your Bridge/Router

This chapter describes the key features and applications of your Prestige 153/153X WAN
Bridge/Router.

1.1 Prestige 153/153X WAN Bridge Routers

Congratulations on the purchase of your ZyXEL Prestige 153/153X Remote Access Router. Your
Prestige integrates the routing and bridging functions in a single package, and is ideal for

everything from Internet browsing to receiving calls from telecommuters to making LAN-to-LAN
connections to remote networks.

Both Prestige 153 and 153X are equipped with three WAN (Wide Area Network) ports that can be
connected to the PSTN (Public Switched Telephone Network) via modems or to the ISDN
(Integrated Service Digital Network) via TAs (Terminal Adapters).

In addition, the Prestige 153X supports synchronous mode on two of the WAN ports, allowing it
to connect to FT1/FE1 (Fractional T1/E1) leased lines via CSU/DSUs (Channel Service Unit/Data
Service Units).

1.2 Features of Prestige 153/153X

The following are the key features of the P153/P153X.

• Multiple WAN Ports

Your Prestige 153 features three WAN ports (WAN-1, 2 and 3). Each WAN port can be connected
to a dial-up/leased line modem or to an ISDN TA (Terminal Adapter). The WAN ports can be
used independently, or they can be bundled to support PPP Multilink Protocol (PPP/MP) to boost
bandwidth.

Two of the WAN ports on P153X also support synchronous mode operation for leased lines.

• Leased Lines Backup

• 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.

Prestige 153/153X WAN Bridge/Routers

• 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 to speed up data transfer. Stac is the de facto
standard of data compression over PPP links.

• 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.

1.3 The WAN Ports

The WAN ports are high-speed, asynchronous RS-232 serial ports that allow you to connect a
modem or an ISDN Terminal Adapter (TA) to the Prestige. Two of the ports on P153X can be
configured to support synchronous operation, also. The WAN ports support up to 230.4kbps
(kilobits per second) throughput. For brevity’s sake, we will refer to the modem and the TA
categorically as “external WAN device”, or simply “WAN device” from now on.

1.3.1 WAN Terminology

• DCE & DTE

On the two ends of an RS-232 connection, the equipment closest to the telephone line is called the
DCE (Data Communications Equipment) and the other the DTE (Data Terminal Equipment). In
our case, the modem or the ISDN TA is the DCE, and the Prestige is the DTE.

• PSTN & POTS

Collectively, the interconnected network of the voice grade networks of the individual telephone
companies is called PSTN (Public Switched Telephone Network), and a regular telephone line is
often referred to as a POTS (Plain Old Telephone Service) line.
