Select the desired WAN Interface Protocol and enter the WAN Interface Bandwidth to as-
sure the quality of IP calls.  

 

Fig. I-19: Internet Configuration Wizard - Uplink Configuration  

If the available bandwidth is used to the point where the quality of an additional IP call 
would suffer, then new IP calls are rejected. 
 
The bandwidth provided by your ISP must be specified for both Upstream  and  Down-
stream fields. The default entry in both fields is 10000, the maximum bandwidth of the 10 
MB uplink module.  For basic DSL and cable modem service in the United States, typical 
values are 300 for Upstream and 1500 for Downstream.   
The Min Data Rate text field is used to specify the amount of bandwidth reserved for data 
applications. The value entered here needs to be smaller that the value specified for Up-
stream Bandwidth.  
Specify the WAN Interface Protocol by choosing between available WAN interface proto-
cols: PPPoE (Point to Point over Ethernet), PPTP (Point to Point Tunneling Protocol) and 
Ethernet. Use Ethernet for DHCP or static IP.

WAN Interface Protocol, PPP/PPTP Configuration page will follow the WAN IP Configu-
ration.

 

 
Your Internet Service Provider (ISP) should provide this information.  

• 

Assign automatically via DHCP - The parameters are set automatically by the ISP. 
This is common with cable modem and DSL service. 

• 

Assign Manually requires the administrator to enter the external IP Address, the cor-
responding  Subnet Mask, and the IP address of the Standard Gateway. This is 
common when you have a static IP address with your ISP.
