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 a/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. It can also
function as a DLNA/media server.
•
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.
See the chapter on product specifications for a full list of features.

1.2.1
Internet Access
Your ZyXEL Device provides shared Internet access by connecting the DSL port to
the
DSL
or
MODEM
jack on a splitter or your telephone jack. If you prefer not to
use a DSL line and you have another broadband modem or router (such as ADSL)
available, you can push the
DSL/WAN
switch (on the rear panel) to the
WAN
side and connect the
WAN
port to the broadband modem or router. This way, you
can access the Internet via an Ethernet connection and still use the QoS, Firewall
and VoIP functions on the ZyXEL Device.
Computers can connect to the ZyXEL Device’s LAN ports (or wirelessly).
Figure 1
ZyXEL Device’s Internet Access Application
1.2.1.1
3G WAN
The USB port allows you to wirelessly connect to a 3G network to get Internet
access by attaching a 3G wireless card. You must leave the DSL or Ethernet WAN
port unconnected and attached a 3G wireless card to use 3G as your WAN. You
can also have the ZyXEL Device use the 3G WAN connection as a backup. That
means the ZyXEL Device switches to the 3G wireless WAN connection after the
wired DSL or Ethernet WAN connection fails. The ZyXEL Device automatically
changes back to use the wired DSL or Ethernet WAN connection when it is
available.

You can also configure firewall on the ZyXEL Device for secure Internet access.
When the firewall is on, all incoming traffic from the Internet to your network is
blocked unless it is initiated from your network. This means that probes from the
outside to your network are not allowed, but you can safely browse the Internet
and download files.
Use QoS to efficiently manage traffic on your network by giving priority to certain
types of traffic and/or to particular computers. For example, you could make sure
that the ZyXEL Device gives voice over Internet calls high priority, and/or limit
bandwidth devoted to the boss’s excessive file downloading.
1.2.2
VoIP Features
You can register up to 2 SIP (Session Initiation Protocol) profiles (4 accounts for
each profile) and use the ZyXEL Device to make and receive VoIP telephone calls:
Figure 3
ZyXEL Device’s VoIP Application
The ZyXEL Device sends your call to a VoIP service provider’s SIP server which
forwards your calls to either VoIP or PSTN phones.
1.2.3
ZyXEL Device’s USB and DLNA Media Support
Use the built-in USB 2.0 port to share files via a USB memory stick or a USB hard
drive (
A
). Alternatively, you can add a USB printer (

) and make it available on
your local area network.

) to play
media files stored in the USB storage device in your TV screen.

Wireless Connection
By default, the wireless LAN (WLAN) is enabled on the ZyXEL Device. IEEE
802.11a/b/g/n compliant clients can wirelessly connect to the ZyXEL Device to
access network resources. You can set up a wireless network with WPS (WiFi
Protected Setup) or manually add a client to your wireless network.

The WPS/WLAN Button
You can use the
WPS
button (
) on the top of the device to turn the wireless
LAN off or on. You can also use it to activate WPS in order to quickly set up a
wireless network with strong security.

LED should flash while the ZyXEL Device sets up a WPS connection
with the wireless device.
Note: You must activate WPS in the ZyXEL Device and in another wireless device
within two minutes of each other. See
Chapter 6 on page 145
for more
information.
