CHAPTER 1 Introduction 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. 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 802.11 b/g/n wireless LAN connectivity. • "U" denotes a USB port used to set up a 3G WAN connection via a 3G wireless card or share files via a USB memory stick or a USB hard drive. The ZyXEL Device can function as a print server with an USB printer connected. • "L" denotes the PSTN (Public Switched Telephone Network) line feature. The PSTN line lets you have VoIP phone service and PSTN phone service at the same time. All PSTN line features documented in this user's guide refer to the "L" models only. When the ZyXEL Device does not have power, only the phone connected to the PHONE port 1 can be used for making calls. Ensure you know which phone this is, so that in case of emergency you can make outgoing calls. • Models ending in "1", for example P-2612HNU(L)-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. See the chapter on product specifications for a full list of features. P-2612HNU(L)-FxF User's Guide 21

Overview
The ZyXEL Device is an ADSL2+ Integrated Access Device (IAD) that combines an
