Getting To Know the ZyXEL
Device
This chapter describes the key features and applications of your device .
1.1 Introducing the ZyXEL Device
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.
Please refer to the following description of the product name format.
• 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.
Note: 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.
