TVP-224HR User’s Guide
93
The previous section dealt with the TVP-222H in and its configuration in a static IP
environment. The following section will address the issue of Dynamic IP and the
TVP-224HR deployment in such an environment. This section we will shows you how
to connect two TVP-224HR in a dynamic IP address environment and configure
PPPoE, DHCP, and DDNS clients.
In addition to fixed IP, the TVP-224HR can be configured to use PPPoE or DHCP
clients. With PPPoE and DHCP, you will under most circumstances be assigned a
Dynamic IP. In order for other people and devices to locate you, they will need to be
pointed to your dynamic IP. Therefore, it is necessary that you register with a DDNS
(Note: www.dyndns.org is currently the only service supported). Once you have
registered an account, and have configured the DDNS client in the TVP-224HR, the
TVP-224HR will automatically notify DynDNS of your changing IP Address.
DynDNS will in turn, map your Dynamic IP to your registered Domain Name. See
Chapter 6, DDNS section for more information.
The first time you connect to the TVP-224HR for configuration, you will need to
connect to it under the same LAN segment to set the DHCP or PPPoE client. To
configure the TVP-224HR, insert one end of an Ethernet cable into one of the 4 RJ45
LAN ports on the rear panel of the TVP-224HR and the other end directly to your PC
Terminal. By default, the TVP-224HR’s DHCP server is enabled. Make sure your
computer is DHCP client enabled (See Chapter 4, PC Configuration). If you choose to
assign a Fixed IP to your PC, make sure that you do not assign a IP that that is already
allocated to the DHCP server for DHCP clients. The TVP-224HR supports auto
MDIX so Cat 5 cable will be sufficient.
Case 4: Gateway Prefix–Simplified Gateway Phone to Gateway Phone
After these dial plans are added, users on Site A are able to dial “22 + extension
number” to connect to users on site B for free VoIP telephony. Users on Site B are
able to call phones on Site A for free VoIP telephony by dialing “11 + extension
number”. (Note: There is a Max digit (5) limitation on the dial plan which allows the
TVP-224HR to differentiate with potential PSTN numbers that may start with 11 or 22
but because they exceed 5 digits, they would be handled differently).
The benefits of this dial plan are:
1. Simplified setup
2. VoIP (Free calls to remote site extension)
3. Simplified dialing ensures easy, direct access to remote extensions.
4. Simplified dialing makes remote offices and branches feel like local
extensions.
Two TVP-224HR Gateways (Both Gateways are set up with default settings)
1. TVP-224HR A, located site A
2. TVP-224HR B, located on site B.
