The bandwidth provided by the ISP has to be specified in the text fields Upstream Speed and Downstream Speed. The default entry in both fields
is 10000, the maximum bandwidth of a 10 MB Ethernet. But most providers offer a smaller bandwidth than these 10000 kbit/s.
The bandwidth required by an IP call depends on the codecs used and is listed in the tables below:
Required Bandwidth for Standard Packets:
Needed bandwidth in kbit/s using the Codecs: Packet

The Min Data Rate text field requires the amount of upstream bandwidth that ought to remain for data applications even if voice applications use the
entire available upstream bandwidth. The value selected here needs to be smaller than the upstream bandwidth and is measured in kbit/s.
The WAN IP Configuration page only is displayed if Ethernet or
PPTP has been selected to be the uplink protocol. It offers the
following components:
The Assign automatically via DHCP radio-button selection switches
to automatic retrieval of the WAN IP address from a DHCP server at
the ISP/uplink.
Please Note: DHCP refered to here is the one running on the
provider’s side and not the Quadro’s personal DHCP server.
The Assign Manually radio-button switches to the manual
adjustment of IP settings. This selection requests the following
parameters:
IP Address requires the IP address for the Quadro WAN interface.
Subnet Mask requires the subnet mask for the Quadro device WAN
interface.
Default Gateway requires the IP address of the router all packets are
sent to, for example, the router of the provider.
