User's Manual
Select one of the following Internet Protocol options from the 'Internet Protocol' drop down
menu:
„ No IP Address
„ Obtain an IP Address Automatically
„ Use the Following IP Address
Note that according to the selection you make in the 'Internet Protocol' drop down menu,
the screen refreshes and displays relevant configuration settings.
„ No IP Address: Select 'No IP Address' if you require that your Telephone Adapter has
no IP address. This can be useful if you are working in an environment where you are
not connected to other networks, such as the Internet.
„ Obtain an IP Address Automatically: Your WAN connection is configured by default
to act as a DHCP client. You should keep this configuration in case your service
provider supports DHCP, or if you are connecting using a dynamic IP address. The
server that assigns the Telephone Adapter with an IP address, also assigns a subnet
mask. You can override the dynamically assigned subnet mask by selecting the
'Override Subnet Mask' and specifying your own mask instead. You can click the
Release button to release the current leased IP address. Once the address has been
released, the button text changes to 'Renew'. Use the Renew button to renew the
leased IP address.
„ Use the Following IP Address: Your WAN connection can be configured using a
permanent (static) IP address. Your service provider should provide you with this IP
address, subnet mask and the default Telephone Adapter IP address.
11.1.2.1.1 IP Address Distribution
The 'IP Address Distribution' section allows you to configure the device's Dynamic Host
Configuration Protocol (DHCP) server parameters. The DHCP automatically assigns IP
addresses to network PCs. If you enable this feature, make sure that you also configure
your network PCs as DHCP clients. For a comprehensive description of this feature, refer
to Section 10.28.
Select one of the following options from the 'IP Address Distribution' drop-down list:
Table 11-2: IP Address Distribution Parameters
Parameter Description
DHCP Server Start IP Address The first IP address that may be assigned to a LAN host.
Since the device's default IP address is 192.168.2.1, this address must be
192.168.2.2 or greater.
End IP Address The last IP address in the range that can be used to automatically assign IP
addresses to LAN hosts.
Subnet Mask A mask used to determine to what subnet an IP address belongs. An example
of a subnet mask value is 255.255.0.0.
Lease Time In
Minutes Each device is assigned an IP address by the DHCP server for a this amount
of time, when it connects to the network. When the lease expires the server
determines if the computer has disconnected from the network. If it has, the
server may reassign this IP address to a newly-connected computer. This
feature ensures that IP addresses that are not in use become available for
other computers on the network.
