The rear panel of the TVP-221H has four analog telephony ports, two FXO and
two FXS ports offering flexible telephony interface usage.
The FXS telephony
interface ports may be connected to Subscriber Equipment, such as Telephones,
Fax Machines, Cordless Phones, and Modems. FXO ports can be connected to
PBX and local phone company Central Office (CO) lines. In addition to analog
telephony interface ports, there is a power jack for power adapter connection on

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 TVP-
221H is placed in a clean, well-ventilated, and vibration-free environment.
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

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.
