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.
