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
