Broadband Modem, Multiple PCs and a Hub

multiple public IP addresses are available.
In order to install the DVC-1000 VideoPhone as another device behind a hub assign an
available public IP address to the VideoPhone.
Refer to the Broadband Modem Only section, below, for detailed installation instructions.
Broadband Modem, Multiple PCs and a Router
Commonly found in small offices, home offices, or homes with more than one PC where
only one public IP address is available.
Refer to the Using the DVC-1000 with Routers, Gateways or Broadband Modems section
starting on page 43 for detailed installation instructions.
Broadband Modem Only
This section applies only in the instance that the broadband connection is used exclusively
with the DVC-1000 VideoPhone and there are no PCs or other devices connected to the
broadband modem. Broadband cable modems allow this type of installation.
Recommended Procedure: Many ISPs act as DHCP servers and dynamically assign a
public IP address whenever the modem requests one. If your ISP has a DHCP server,
select the checkbox under the Network Settings. By choosing this option, you are not
required to know the IP address, gateway, subnet mask, or DNS numbers. They will all
be filled in automatically.
If your ISP offers Fixed IP addresses (also called Static IPs), all of the networking values
will have to be manually entered. Simply enter the public IP address, subnet mask,
gateway, and DNS numbers given to you by the ISP into the appropriate network settings
fields.
If you have a DSL modem, which offers a PPPoE connection, choose the PPPoE option
on the network settings screen. Fill in your username and password to authenticate.
Potential Issues: In order for the DVC-1000 VideoPhone to function properly over the
Internet, there must exist a public IP address for the world to see. If your ISP is acting as
a NAT and assigning private IP addresses, you will have to request a public IP address
in order for your VideoPhone to be able to receive calls.
