1. Introduction
Congratulations on your purchase of a ZyXEL Prestige 128IMH Remote Access Router. In
a modem-sized box, the Prestige offers inexpensive yet complete telecommunications and
internetworking solutions for your home or branch office. The Prestige is ideal for
everything from surfing the Internet to receiving calls from remote dial-in users to making
LAN-to-LAN connections to remote nodes.
Distinguishing features of the Prestige 128IMH include remote dial-in user support, an
Internet Single User Account (Network Address Translation), POTS line support (Plain Old
Telephone Service; also called A/B Adapter in Europe), extensive Network Management,
built-in 4-port Ethernet hub and the latest security features.
1.1. Features
The Prestige 128IMH is packed with a number of features that give it the flexibility to
provide a complete networking solution for almost any user.
1.1.1. Built-in V.90 Modem
This Prestige has a built-in V.90 modem. This enables it to communicate to remote routers
or users at speeds up to 56 Kbps through the ISDN connection.
1.1.2. Ease of Installation
The Prestige is a self-contained unit that is quick and easy to install. Physically, it
resembles an external modem except for the fact that it is a router and uses Ethernet cables
to connect to the host network.

Using a standard BRI S/T interface, the Prestige supports a full range of switch types. The
switch type depends on the Central Office switch ISDN line. The two B-channels can be
used independently for two destinations or they can be bundled for a single connection with
PPP/MP.
