CHAPTER 1
Introducing the ZyXEL Device
1.1 Overview
The ZyXEL Device is an ADSL2+ Integrated Access Device (IAD) that combines an
ADSL2+ router with Voice over IP (VoIP) communication capabilities to allow you
to use a traditional analog 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.
Please refer to the following description of the product name format.
• “H” denotes an integrated 4-port hub (switch).
• “N” denotes wireless functionality, including 802.11n mode. There is an
embedded mini-PCI module for IEEE 802.11b/g/n wireless LAN connectivity.
• “U” denotes a USB port used to share files via a USB memory stick or a USB
hard drive. The ZyXEL Device can also function as a print server with an USB
printer connected.
• Models ending in “1”, for example P-2612HNU-F1, denote a device that works
over the analog telephone system, POTS (Plain Old Telephone Service). Models
ending in “3” denote a device that works over ISDN (Integrated Services Digital
Network) or T-ISDN (UR-2).
Only use firmware for your ZyXEL Device’s specific model. Refer
to the label on the bottom of your ZyXEL Device.
