The TVP-221H supports several industry-standard networking protocols required
for voice communication. The following table describes these protocols.
Networking Protocol Description
Internet Protocol (IP) IP is a messaging protocol that addresses and sends packets
across the network. To enable IP protocol, the TVP-221H
must have a Real IP address, subnet, and gateway assigned
to it.
Voice over IP Protocol
(VoIP)
Trivial File Transfer
Protocol (TFTP)
Real-Time Transport
(RTP)
VoIP enables the TVP-221H to transfer voice
communications over an IP network. The TVP-221H
employs ITU-T H.323 protocol for setting up calls with
one another.
TFTP allows you to transfer files over the network. The
TVP-221H implements a TFTP client allowing you to
download new revision firmware from a TFTP server. The
TFTP client requires a TFTP server in your network.

Chapter 2
Installing the TVP-221H
This chapter gives information on how to install the TVP-221H.
2.1 Network Requirements
For the TVP-221H to successfully operate in your network, your network must
meet the following requirements:
1. A working 10/100 Base-T Ethernet. The TVP-221H connects to the Internet
via an Ethernet LAN.
2. IP network that supports gateway, and subnet mask. You’ll need a static IP
address to assign the TVP-221H or a DDNS account for your Dynamic IP.
2.2 Installing the TVP-221H
Due to the TVP-221H being used in a desktop configuration, ensure that the TVP221H is placed in a clean, well-ventilated, and vibration-free environment.
2
When the TVP-221H is used, be certain that the unit is placed on a sturdy, flat
surface, near a grounded power outlet. At least three inches of clearance must be
provided on both sides of the TVP-221H for good ventilation.
2.3 Connecting to the telephony devices
The 4 port TVP-221H supports 2 FXO and 2 FXS. Each RJ11 port is for
connecting to telephony devices.
The FXO port is designed for connecting to PBXs or local telephone company
central office switches (CO).
The FXS port is designed for connecting to analog telephone sets, G3 fax
machines.
Warning: connection of incorrect telephony devices to the ports on the TIM can
cause permanent damage to the TIM and/or the TVP-221H.
2.4 Connecting to the Network
The RJ45 network port on the rear panel supports 10/100 Mbps half-duplex
connections to Ethernet. You can use either Category 3 or 5 straight-through UTP
cable for 10 Mbps connections, but use Category 5 for 100 Mbps connections.
TVP-224 supports PPPoE and DDNS so it can be connected directly to your Cable
/ ADSL modem, or under a Router. 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
14
TVP-221H User’s Guide
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 configuring
PC and connect it directly to your ADSL Cable Modem or place it under a router
as configured.
2.5 Providing Power to the TVP-221H
To provide power to the TVP-221H complete the following steps:
1. Connect one end of the power cord that came with the TVP-221H to the
power jack on the rear panel.
2. Connect the other end of the power cord to an AC power outlet.
3. The TVP-221H will execute memory and application code testing
automatically.
2.6 Assigning 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.

Chapter 3
TVP-221H Telephony
Concepts
The TVP-221H enables the transmission of voice and fax traffic over any IP network by
digitizing voice and fax signals, encapsulating the information within IP packets, and then
sending the packets across the IP network
3.1 How the TVP-221H Operates
1. The TIM inside the TVP-221H digitizes analog voice signals at 8 Kbps.
2. TVP-221H system software handles the:
• Capture of telephone number presented as DTMF tones.
• Mapping the telephone number to the IP address of remote VoIP
Gateway.
3
• Setting up calls with remote TVP-221Hs utilizing H.323 call control
protocol.
• Digitizing, compressing and encapsulating the voice into IP packets and
transmission of the IP packets onto the Ethernet LAN.
3. A router attached to the LAN forwards the IP packets across the WAN, where
they will be received by another VoIP Gateway at the remote.
4. The process is reversed at the remote VoIP Gateway.
3.2 ATPM
To allow you to easily dial a telephone or fax on the network, the TVP-221H
maps a series of dialed digits to the IP address of the remote TVP-221H whose
phone or fax you are calling. This mapping information is contained in a database
inside each TVP-221H called the dial plan.
Based on the dial plan, the Address Translation and Parsing Manager (ATPM)
inside the TVP-221H maps telephony numbers to IP addresses of remote VoIP
Gateways. The ATPM collects telephone number dialed by users, decides whether
the dial string is part of the dial plan and, if it is, maps it to a remote TVP-221H /
TVP-224HR. When the call is set up to the destination, a sub-string of the original
dial string will be sent along to the remote VoIP Gateway.
3.3 Destination
The destination is where a call is terminated. Typically, for inbound calls from the
IP network, the TVP-221H terminals the call at one of the telephony ports. The
16
TVP-221H User’s Guide
destination for the call is the telephony port where the call terminated. For calls
initiated from telephony ports, the TVP-221H forwards the call to a remote TVP221H/TVP-221H via IP network, and the remote TVP-221H/TVP-221H
terminates the call. The destination of the call is the remote TVP-221H/TVP224HR.
3.4 Hunt Group
Instead of directly mapping a phone number to a destination, the ATPM first maps
the phone number to a group of destinations known as a Hunt Group. A hunt
group is a group of destinations that are equivalent.
support group of a company might have 20 people who can handle support
calls. Access to customer support is through a single phone number but the
next available support person is actually connected upon each incoming
call. These 20 phones would be configured as a hunt group. A hunt group
consists of a phone number and a list of destinations (members of the
group). When an incoming phone number matches the phone number of the hunt
group, the TVP-221H attempts to terminate the call at each of the destinations in
the hunt group, one at a time until a call is successfully completed.
Every destination that can be reached by dialing a phone number is a member of at
least one hunt group. When an address is presented to ATPM for lookup, the
output is a hunt group ID number. As a second step, the hunt group ID is
presented to ATPM to get the list of members. To effectively bypass the hunt
group feature, simply assign a unique hunt group number to a single destination.
In effect, the Hunt Group will just have this one member.
For example, the customer
3.5 Dial Plan
The dial plan is a database inside the TVP-221H that allows the ATPM to map
telephone numbers dialed to IP addresses of remote VoIP Gateways. The dial plan
consists of three tables; destination table, hunt group table and the address table.
Users need to setup these tables in order for the TVP-221H to process calls to
remote VoIP Gateways.
3.51 Address Table
The address table maps a phone number to a hunt group. The table contains entries
that specify the following information:
• Telephone number
• The hunt group the phone number maps to.
• The minimum number of digits to collect before the ATPM starts address
lookup.
• The maximum number of digits the ATPM collects before it considers the
dial string is complete.
• Number of digits forwarded to the destination.

3.6 DTMF Relay
Voice from PSTN is compressed by the TVP-221H before it is sent across the IP
network and then decompressed by the destination VoIP gateway. The voice
codecs supported by the TVP-221H are designed for ideally compressing and
decompressing human voice. If the compression / decompression process is
performed on DTMF tone which needs to be conveyed across IP network,
distortion might be too significant to be cognizable on the receiving end. To
overcome the shortcoming that the voice codecs may have encoding DTMF tone,
the TVP-221H encodes DTMF tone into special packets. The packets are then sent
to the destination VoIP Gateway via a separate IP connection. The destination
VoIP Gateway decodes the packets, generates the DTMF tone, and then sends the
18
TVP-221H User’s Guide
tone to the PSTN. This method in which the TVP-221H handles DTMF tone is so
called DTMF relay.
The TVP-221H handles DTMF relay per H.323 specifications. Certain third party
VoIP devices may handle DTMF relay per IMTC standard. For the TVP-221H to
interoperate with those VoIP devices, users need to specify which remote VoIP

4.2 Internet Access
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..
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. The default TVP-221H IP address is 192.168.0.1. To configure the TVP221H, 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.

constantly changing making it difficult for internet users to find you.
The Service works as follows:
1. Obtain a free account for the service by registering at
2. www.dyndns.org will automatically notify you confirming your account
information.
3. Return to
your preferred Domain name. It is recommended that you register a name within

This is a separate feature to PLAR. If you would like to have the
Caller’s Identification including Number and Name forwarded to the
recipient, please provide the information in the provided fields..
On/Off
Private-line automatic ringdown (PLAR) circuits have statically configured
endpoints and do not require the user dialing to connect calls. The PLAR
feature provides an easy method to create a switched Voice over IP (VoIP)
call without digit dialing. PLAR connections are often referred to as a "batphone" or “hotline” type of application. This is when a phone goes off-hook
35
and a remote phone rings without digits being dialed. This is a useful tool for
customer requirements such as:
• The provision of an Off-Premises eXtension (OPX) from a private
branch exchange (PBX). Connection PLAR allows remote users on
Foreign Exchange Station (FXS) ports to look to a central PBX like
physical extensions.
• The provision of dial-tone from a remote PBX. Many customers want to
offer toll-bypass VoIP services without having the routers provide dialtone or change their existing dialplan. This allows stations at remote sites
to look like they are physically connected stations to a PBX.
Dial in PLAR Considerations and Limitations
• Dial in PLAR is a switched VoIP call. The call is setup on an as-needed
basis. With connection PLAR, no bandwidth is consumed while the
phone is on hook. When a phone connected to a POTS dial peer is taken
off-hook, the call is automatically connected and the remote phone
begins to ring.
• Dial in PLAR can work between any type or combination of Foreign
Exchange Office (FXO), and/or FXS) telephony port / device.
TVP-221H User’s Guide
• Dial in PLAR does not collect digits from the connected Telephony
device. Once a dial plan has been entered into the ATPM, PLAR can be
enabled without need to alter the dial plan. Note: All other Dial plans set
for this starting port will become ineffective.
4.43 Store Dial Plan
Store Dial Plan - will store the Dial Plan from DRAM / Working Memory to
Flash / Non-Volatile Storage
Always be sure to Store, the Dial Plan from working memory / DRAM to

ensures that you have saved the dial plan which can then be restored on
request.
Note: The Dial Plan in the Non-Volatile Storage is not the working Dial Plan.
If the Gateway is turned off for what ever reason, the Dial Plan from NonVolatile Storage is copied into the Flash / Working memory and processes
phone calls accordingly

Then dial ‘316’, your extension handset should ring right away.
This guide only uses the default values. Once you are familiar with
the dial plan set up, you may design your own dial plan.
5.2 Making a call with TVP-221H FXS Port
TVP-221H has two FXS ports. An FXS port can connect to an analogue phone
directly, and a FXO port can connect to a PBX system or CO line.
Connection: Analogue telephone set
connects to FXS port

TVP-221H User’s Guide
Operation:
1. Pick up this analogue telephone set. You should be able to hear the dial tone
provided by the TVP-221H.
2. The corresponding green LED will light up when the telephone set is picked
up. For Example: If the telephone set is connected to the second port of FXS.
When you pick up the telephone set, the second green LED will light up.
3. We can dial the desired destination phone number at the telephone set. If the
desired destination phone number is legal, the TVP-221H will play two
quick address ack tones, Du Du, to destination. If the desired destination
phone number is illegal, the TVP-221H will play three out of service tones,
please check the dial plan and your desired destination phone number.
5.3 Making a call with TVP-221H FXO Port
Connection: Analogue PBX connects to FXO port
Operation:
1. Pick up this analogue telephone set, you
can hear the PBX dial tone provided by
the PBX system. In some cases, you
have to dial a specific number to get the
connection between telephone set and
PBX.
2. Dial the extension number for the
gateway as provided by the PBX for the TVP-221H FXO port.
3. When the TVP-221H is connected, the corresponding green LED will be
illuminated. For Example: If the telephone set is connected to the second FXO
port, the second LED will be green.
4. We can dial the desired destination phone number on the telephone set. If the
desired destination phone number is legal, the TVP-221H will play two quick
sounds, “Du Du”, to destination. If the desired destination phone number is
illegal, the TVP-221H will play three out of service tones, please check the dial
plan and your desired destination phone
number.
5.4 Web Browser Sample Dial Plan

TVP-221H User’s Guide
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 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.

5.6 VoIP in a Dynamic IP environment
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-221H deployment in such an environment. This section we will shows
you how to connect two TVP-221H in a dynamic IP address environment and
configure PPPoE, DHCP, and DDNS clients.
5.7 PPPoE, DHCP, and DDNS clients:
Case 4: Gateway Prefix–Simplified Gateway Phone to Gateway Phone
In addition to fixed IP, the TVP-221H 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:
registered an account, and have configured the DDNS client in the TVP-221H, the
TVP-221H will automatically notify DynDNS when your Dynamic IP Address
changes. DynDNS will in turn, map your Dynamic IP to your registered Domain
Name. See Chapter 6, DDNS section for more information.
www.dyndns.org is currently the only service supported). Once you have
55
TVP-221H User’s Guide
The first time you connect to the TVP-221H 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-221H, insert one end of an Ethernet cable into the RJ45 WAN port
on the rear panel of the TVP-221H and the other end directly to your PC Terminal.
Open your browser and enter the TVP-221H’s default IP Address: 192.160.0.1. Make
sure your computer’s Fixed IP is in the same segment. (See Chapter 4, PC
Configuration). 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.
Dial Plan
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 dial plan which allows the
TVP-221H 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-221H Gateways (Both Gateways are set up with default settings)
1. TVP-221H A, located site A
2. TVP-221H B, located on site B.
Registered DDNS name for both Dynamic IPs
• tvp1.dyndns.org is applied for TVP-221H on site A
• tvp2.dyndns.org is applied for TVP-221H on site B
Clients used on this topology :
• TVP-221H on site A has PPPoE, and DDNS clients enabled
• TVP-221H on site B has DHCP, and DDNS clients enabled.

5.8 (NAT) router with built-in DDNS client
Case 5: Gateway Prefix-Simplified Gateway Phone to Gateway Phone
A major consideration in NAT to NAT VoIP communication is that the DMZ function
and DDNS Client of the NAT routers have to function correctly. If they do not, it will
result in one-way communication. The following Case example explains how the
61
TVP-221H User’s Guide
TVP-221H can be configured with a Router. In this example, Trendwares TEW431BRP is used.
Internet Access
In addition to fixed IP, the TEW-431BRP can be configured to use PPPoE or DHCP
clients. With PPPoE and DHCP, you will have a Dynamic IP but combined with
Dynamic DNS, the TEW-431BRP will automatically notify DynDNS of your
changing IP Address and DynDNS will in turn, map it to your registered Domain
Name. Assuming the above has been done, we can configure the TVP-221H
Note: The following installation method takes into consideration that both the TEW-
431BRP and the TVP-221H have the same default IP address: 192.168.0.1. Please
note that the TEW-431BRP DHCP Server start IP Address and finish IP Address
fields set the values used by the DHCP server when allocating IP Addresses to DHCP
clients. Please set the DHCP Server values to avoid conflict with the Fixed IP
addresses assigned to the TVP-221H A (192.168.0.20) and TVP-221H B
(192.168.0.55)
The first time you connect to the TVP-221H for web configuration, you will need to
connect to it under the same LAN segment. To configure the TVP-221H, insert one
end of an Ethernet cable into the RJ45 LAN port of the TVP-221H and the other end
directly to your configuring PC.
Once Internet Access has been configured (See below), you can disconnect the cable
from the PC and reconnect it to one of the LAN ports of the TEW-431BRP. Connect
your PC to one of the remaining 3 Hub ports. By default, the TEW-431BRP’s DHCP
server is enabled. Make sure your computer is DHCP client enabled or has a Fixed IP
not used by any other devices on the LAN. If using a Fixed IP, make sure it is also in
the same LAN segment.. See Chapter 4 for more information. The TEW-431BRP and
the TVP-221H both support auto-MDIX so a Standard Cat 5 cable will be sufficient.
Network Configuration
In this case application, the Trendware TEW-431BRP can be set up to use Virtual
Servers or DMZ, and DDNS Client Support
1. The TEW-431BRP supports Virtual Servers and DMZ allowing you to connect a
device / server you wish to make available to the public. Using a standard RJ45
cable, connect your TVP-221H LAN port to a TEW-431BRP LAN port.
Please note the following regarding DMZ configuration.
• Devices connected to a LAN port are in the same LAN segment as PCs
connected to the other LAN ports. They must use the same IP address range.
2. Select Internet on the main menu, then Dynamic DNS, to see a screen like the
following
62
TVP-221H User’s Guide
3. Enter username / password and domain name (hostname) as registered with
www.dyndns.org
4. Click on Save, and wait a few seconds to verify if DDNS service has taken effect.
DDNS Status should appear. You can also verify by checking the Status page.
Note: When setting up the DDNS Client, it is advised that you register a
hostname with only dyndns.org domain.
Note: DDNS feature implementation may be different for different routers from
different vendors. Please refer to respective vendor’s user’s manual for
DDNS feature explanation and configuration
Note: Please note that DDNS client in TVP-221H is not suggested in NAT
environments.
5. From the Internet menu, navigate to the Virtual Servers submenu. The following
menu will appear.

TVP-221H User’s Guide
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
dial plan which allows the TVP-221H 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.
Network Deployment
Two TVP-221H Gateways (Both Gateways are set up with default settings)
1. TVP-221H A, located site A
2. TVP-221H B, located on site B.
Register DDNS name for both Dynamic IPs (See Chapter 4)
• tvp1.dyndns.org (xxx.xxx.xxx) is applied for TEW-431BRP on site A
• tvp2.dyndns.org (xxx.xxx.xxx) is applied for TEW-431BRP on site B
Clients used in this topology:
• TEW-431BRP on site A has PPPoE, and DDNS clients enabled
• TEW-431BRP on site B has DHCP, and DDNS clients enabled.
Other considerations for this configuration:
• TVP-221H on site A is connected to a LAN port, Virtual Server is
enabled.
• TVP-221H on site B is connected to a LAN port, Virtual Server is
enabled.

Connection Considerations
This section discusses the special connection consideration for various environments and
situations where you can use the VoIP Gateway.
6.1 Port Configuration
VoIP Gateway supports FXS and FXO ports.
FXS (Foreign Exchange Station)
FXS provides power and ringing signals to its interfacing equipment. It is not
intended for connection to the Public Switched Telephone Network. It is a station
loop start operation that provides a connection to:
1. A standard, single-line analog telephone system
2. The line circuit of a key telephone system
3. A loop start trunk circuit of a Private Branch Exchange (PBX) that normally
connects to incoming Central Office circuits
FXO (Foreign Exchange Office)
FXO recognizes signals and draws current to indicate an active state. It is a trunk
loop start operation that emulates a single-line telephone to:
1. Central Office lines
2. PBX station
There are two basic environments that the TVP-221H can be applied to. They are
described in the following sections.

Application 2: FXO Connections
Application 2 has three possible connections. One Site A, the FXS connection to
analog devices is normal and is identical to connections mentioned in Application
1. On Site B, the connection between PSTN and PBX is also a normal
connection. The last connection is between PBX and the gateway which uses the
internal analogue lines of the PBX. In this case, the FXO port has to be used.
Note: If a digital PBX is used, an analog terminal adapter is needed to provide an
analog interface to the FXO port. Please consult with your PBX supplier.
In this application, the caller on Site A, can make a call using a device connected
to a FXS port on the Site A gateway. The call will be routed to the Site B
Gateway, through a FXO port and passed on to the PBX system. The PBX
system will then forward the call to the dedicated terminal / extension.
