Chapter 1 Getting To Know the ZyXEL Device 41
PSTN Line
You can connect a PSTN line to your device. You can receive incoming PSTN phone calls
even while someone else is making VoIP phone calls. You can dial a (prefix) number to make
an outgoing PSTN call. You can still make PSTN phone calls if your device loses power.
Note: When the ZyXEL Device does not have power, only the phone connected to the
PHONE 1 port can be used for making calls. Ensure you know which phone
this is, so that in case of emergency you can make outgoing calls.
ISDN Line
You can connect a ISDN line to your device. You can receive incoming ISDN phone calls even
while someone else is making VoIP phone calls. You can dial a (prefix) number to make an
outgoing ISDN call.
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.
Any IP
The Any IP feature allows a computer to access the Internet and the ZyXEL Device without
changing the network settings (such as IP address and subnet mask) of the computer, when the
IP addresses of the computer and the ZyXEL Device are not in the same subnet.
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.
