6. Connection through Telnet
To use Telnet, Internet Access must have been previously setup so that the
gateway is visible on the Internet (See User Guide for More Information).
Alternatively, you can use Telnet to locally access the TVP-221H, if you are
under a router or switch and the TVP-221H and your computer are in the same
network segment.
To access the TVP-221H Gateway from a remote location / or from the same
LAN Segment using Telnet, perform the following tasks:

8. Dynamic DNS (Domain Name Server)
This free service is a very useful feature when directly connecting your TVP-
221H to your ADSL / Cable modem or under a router which has enabled virtual
servers or DMZ. It allows Internet users to connect to the TVP-221H using a
URL, rather than an IP Address. This also solves the problem of having a
dynamic IP address. With a dynamic IP address, your IP address may change
whenever you connect to the Internet, making it difficult for others to find /
connect to the TVP-221H. With DDNS, your IP may change but your Domain
Name is Static.
The Service works as follows:
1. You must register for the service at www.dyndns.org using the dyndns.org
domain. This is the only Dynamic DNS service currently supported.
2. After registration, follow the Service Provider's procedure to request a
Domain Name, and have it allocated to you.
Select Internet on the main menu, then DDNS submenu, to see a screen like
the following:

13 English
3. Enable Dyn-DNS. Please be sure to enter the data correctly. For instance, if
you registered johnsmith.dyndns.org, please make sure that “dyndns.org” is
in the Server Name Field and “johnsmith” is in the Host Name Field. Please
also enter “User Name” and “Password”.
4. Click Save.
5. The TVP-221H will then automatically ensure that your current IP Address is
recorded and updated at the DDNS server. If the DDNS Service provides
software to perform this "IP address update"; you should disable the
“Update" function, or not use the software at all.
6. From the Internet, users will be able to connect to your TVP-221H using your
Domain name, shown on this screen.

14 English
A major consideration in NAT VoIP communication is that the DMZ function (or
Virtual Servers / Port Forwarding) and DDNS Client of the NAT routers have to
function correctly. If they do not, it will result in one-way communication. You
will have to configure your router with the DDNS service if you do not have a
Static or Fixed WAN IP. See Section 8 for more information.
TVP-221H under NAT using Fixed IP
Before connecting your TVP221H to your router, first make sure that your
router has Internet access and that the TVP-221H fixed IP has been entered
into the router. By default, the TVP-221H's IP is 192.168.0.1, so make sure the
routers LAN IP is in the same segment and doesn't share the same IP as the
TVP-221H (eg. 192.168.0.2). Please also make sure that the Routers DHCP
Start and Finish IP pool does not conflict with TVP-221H. See Internet Access /
Fixed IP for more information.
Fixed IP: 192.168.0.1
Subnet Mask 255.255.255.0
Default Gateway is the routers LAN IP: eg. 192.168.0.2
DNS Server IP: 168.95.1.1 or as recommended by your ISP
TVP-221H under NAT using DHCP Client
Alternatively, you could enable your router's DHCP Server and configure the
TVP-221H to be a DHCP client. (See Internet Access / DHCP for more
information)
DMZ or Virtual Server (Port Forwarding)
Next, enable your routers DMZ allowing complete access of the TVP-221H (IP
192.168.0.1). To the Internet.
9. Configured under (NAT) router
NOTE: By Default, the TVP-221H Web Access and Telnet Access
management features are enabled. It is strongly recommended that the
administrative password is updated once configuration is done. If you
should forget your password, please see Section 7 Connection through
Console.

15 English
Alternatively, Virtual servers (Port Forwarding) could be enabled on your router
to allow the TVP-221H to freely communicate over the Internet with other
devices. To do this you will have to open the following ports:
Port Protocol Service or Purpose
24
TCP
UDP
HTML for Web User Interface

10. Web Browser Dial Plan Sample
This section describes how to use a web browser to build a dial plan in the
VoIP Gateway. We suggest the following when developing your dial plan:
Draw an application diagram to illustrate / clarify application including:
1. Local gateway: IP setup
2. Local gateway: local telephone number setup
3. Local gateway: remote gateway IP & remote telephone number setup
Note: The Diagram below of Gateway A & B could be any combination
of either the TVP-224HR (connected to switch by WAN port) or the
TVP-221H (Connected by LAN port). The switch that joins these two
gateways serves the purpose of initial lab configuration. Under this
configuration, both TVP Gateway (To also be referred to as GW) must
be in the same IP segment. Once the dial plans have been entered
and tested, the switch would be replaced by the public Internet and the
gateways would then have to be updated with the field application
Internet Access Settings (eg. Public IP Address, Subnet Mask and
Gateway IP Address). In addition, all remote destinations in the dial
plan must be updated with the actual application / field IP Addresses.

17 English
NOTE: This diagram serves the purpose of illustrating the possible
analog phone / PBX / PSTN integration / applications of the Gateway.
However, disconnect cadence provided by your phone company for
your PSTN line and disconnect cadence provided by your PBX may
require additional matching with the gateway. This will require the
assistance of your PBX supplier and /or Systems Integrator. Please also
see User's Guide for additional information.
Scenario description: Two gateways connected by a switch
There are two gateways connected by a switch. They are generically labeled
