Uplink Configuration
Select the desired WAN Interface Protocol and enter the WAN Interface Bandwidth to assure
the quality of IP calls.
Fig.I- 19: Uplink Configuration page
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 Downstream
fields. The default entry in both fields is 100000, the maximum bandwidth of the 100 Mb up-
link 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 ap-
plications. The value entered here needs to be smaller that the value specified for Upstream
Bandwidth.
Specify the WAN Interface Protocol by choosing between available WAN interface protocols:
PPPoE (Point to Point over Ethernet), PPTP (Point to Point Tunneling Protocol) and Ethernet.
Use Ethernet for DHCP or static IP.
For Ethernet, clicking Next will display the WAN IP Configuration page. If PPPoE is the se-
lected WAN Interface Protocol, the next page will be
PPP/PPTP Configuration. For PPTP WAN
Interface Protocol, PPP/PPTP Configuration page will follow the WAN IP Configuration.
