Introducing the ZyXEL Device

This chapter introduces the main applications and features of the ZyXEL Device. It also
introduces the ways you can manage the ZyXEL Device.

1.1 Overview

The ZyXEL Device is an Integrated Access Device (IAD) that combines an ADSL2+ router
with Voice over IP (VoIP) communication capabilities to allow you to use a traditional analog
or ISDN telephone to make Internet calls. By integrating DSL and NAT, you are provided with
ease of installation and high-speed, shared Internet access. The ZyXEL Device is also a
complete security solution with a robust firewall and content filtering.
At the time of writing, this guide covers the following models.

• In the ZyXEL Device product name, "H" denotes an integrated 4-port switch (hub).
• "W" denotes wireless functionality. There is an embedded mini-PCI module for IEEE
802.11g wireless LAN connectivity.
• "N" denotes the ability to connect an ISDN (Integrated Services Digital Network)
telephone to the device.
• "L" denotes the PSTN (Public Switched Telephone Network) line feature.
When the ZyXEL Device does not have power, only the phone connected to
the PHONE 1 port can be used for making calls. Ensure you know which
phone this is, so that in case of emergency you can make outgoing calls.
• "I" denotes the ISDN (Integrated Services Digital Network) line feature.
1. A device that includes both "L" and "I" in the model name can support either a PSTN line or a ISDN
line, but not both at the same time.
