WAN

Use the Configuration > Network > WAN page to
configure your Internet settings for connectivity to Cloud
Features. For example, the Cisco UC320W can allow
you to access firmware upgrades and documentation
after you configure your Internet connection. By default,
the Cisco UC320W will connect by using DHCP.
However, your Internet Service Provider may require
special settings. Refer to the information provided by
your ISP for your Internet service account.
Note: Refer to the on-screen illustration for the location
of the WAN port, where you can connect the Cisco
UC320W to your Internet service. You can position your
mouse pointer over the pointer icon to view the picture

• Estimated Uplink Bandwidth: Choose a rate that is equal to or less than the upstream
bandwidth specified by your service provider. Tip: Consider choosing a setting that is one level
below your provider's advertised limit. This setting helps to ensure that voice is prioritized during
periods of heavy network traffic.
• WAN Type: Choose the type of Internet connection that is required by your service provider.
Then enter the information for the selected WAN type.
WAN Types
• DHCP: Dynamic Host Control Protocol, the default option, is often used with cable modems.
Select this option if your ISP did not assign a static IP address to your account and instead uses
DHCP to assign an IP address dynamically. No other information is required for this selection.
Optionally, you can enter a Domain Name, if provided by your ISP. Note: One disadvantage of
using a dynamic IP address is that if your IP address changes, your Cisco UC320W and all
connected devices will reboot. Telephone service will be interrupted.
• Static IP: Select this option if your ISP provides you with a static IP address. Complete the
required fields. Also complete the optional fields if the information was provided by your ISP.
• PPPoE (DSL): PPPoE is often used with DSL services. Select this option if your ISP uses PPPoE
and the router obtains an IP address by using PPP/IPCP address negotiation. Complete the
required fields. Also complete the optional fields if the information was provided by your ISP.
Finally, configure your connection with the Keep Alive or Connect on Demand option, as
described below.
• Keep Alive: Choose this option to use Keep Alive messages to keep the connection
permanently open, regardless of the level of Internet activity by your users.
• Connect on Demand: Choose this option to open a connection only when a user attempts
to connect to the Internet. In the Maximum Idle Time, enter the number of minutes of
inactivity that will cause the connection to be terminated. This option is recommended if your
billing is based on the time that you are connected.
• PPTP DHCP: Select this option if your ISP uses PPTP (Point to Point Tunneling Protocol) and did
not assign a static IP address to your account. Complete the required fields. Also complete the
optional fields if the information was provided by your ISP. Note: One disadvantage of using a
dynamic IP address is that if your IP address changes, your Cisco UC320W and all connected
devices will reboot. Phone service will be interrupted. Finally, configure your connection with the
Keep Alive or Connect on Demand option, as described below.
• Keep Alive: Choose this option to use Keep Alive messages to keep the connection
permanently open, regardless of the level of Internet activity by your users.
• Connect on Demand: Choose this option to open a connection only when a user attempts
to connect to the Internet. In the Maximum Idle Time, enter the number of minutes of
