Chapter 1 Getting To Know the ZyXEL Device 37
Zero Configuration Internet Access
Once you connect and turn on the device, it automatically detects the Internet connection
settings (such as the VCI/VPI numbers and the encapsulation method) from the ISP and makes
the necessary configuration changes. In cases where additional account information (such as
an Internet account user name and password) is required or the ZyXEL Device cannot connect
to the ISP, you will be redirected to web screen(s) for information input or troubleshooting.
Auto Provisioning
Your VoIP service provider can automatically update your device’s configuration via an auto-
provisioning server.
Auto Firmware Upgrade
Your device gives you the option to upgrade to a newer firmware version if it finds one during
auto-provisioning. Your VoIP service provider must have an auto-provisioning server and a
server set up with firmware in order for this feature to work.
Firewall
Your device has a stateful inspection firewall with DoS (Denial of Service) protection. By
default, when the firewall is activated, all incoming traffic from the WAN to the LAN is
blocked unless it is initiated from the LAN. The firewall supports TCP/UDP inspection, DoS
detection and prevention, real time alerts, reports and logs.
Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).
Content Filtering
Content filtering allows you to block access to Internet web sites that contain key words (that
you specify) in the URL. You can also schedule when to perform the filtering and give trusted
LAN IP addresses unfiltered Internet access.
Media Bandwidth Management
Media Bandwidth Management allows you to specify bandwidth classes based on an
application and/or subnet. You can allocate specific amounts of bandwidth capacity
(bandwidth budgets) to different bandwidth classes.
Dynamic Jitter Buffer
The built-in adaptive buffer helps to smooth out the variations in delay (jitter) for voice traffic.
This helps ensure good voice quality for your conversations.
