2.6Assigning an IP address to the TVP-221H

The IP address is the unique logical address identifying each IP node, such as the TVP-221H, on an IP network. An IP address is a 32-bit number expressed as four decimal numbers from 0 to 255 separated by periods. The TVP-221H can be configured with a fixed IP address, subnet mask and default gateway (typically a router). The TVP-221H can also be setup as a DHCP Client if your network has a DHCP Server (typically a router). Additionally, the TVP-221H can also be configured to use PPPoE. With PPPoE, you will have a Dynamic IP but combined with Dynamic DNS, the TVP-221H will automatically notify DynDNS of your changing IP Address and DynDNS will in turn, map it to your registered Domain Name. Consult your network manager to obtain a unique and static IP address for the TVP-221H, the IP subnet mask and default gateway of your network, and fill out the work sheet in Appendix D before configuring the gateway. Procedures for assigning IP address, default gateway and subnet mask is available in Chapter 4.

The first time you connect the TVP-221H for configuration, you will need to connect to it under the same LAN segment to set the Fixed IP or DHCP, PPPoE clients. To configure the TVP-221H, insert one end of the Ethernet cable into the RJ45 port on the rear panel of the TVP-221H and other end directly to your PC Terminal. The TVP-221H supports auto MDIX so you do not have to worry about the cable. Any Cat 3 or 5 cable will be sufficient. Once Internet Access has been set up, disconnect the TVP-221H from the configuring PC and connect it directly to your ADSL Cable Modem or place it under a router as configured.
