This chapter gives an overview of the 4 ports desktop version VoIP Gateway (TVP224HR) and a detailed description of its front panel and rear panel.
1.1 Features
The TVP-224HR is a cost-effective and highly reliable analog Voice over IP
(VoIP) Gateway Router that offers toll quality voice and real-time fax data over IP
networks. With its embedded architecture, the gateway is ideal for VoIP
applications associated with Remote Office and Branch Office (ROBO)
environments. With its built-in user-friendly interface, the gateway may be
installed easily and conveniently to yield immediate cost savings. One VoIP
Gateway supports up to four voice or Fax communications simultaneously.
Implemented with an efficient Real-Time Operating System (RTOS) and flash
memory, the TVP-224HR provides upgradeable capabilities, so it may be
programmed with updated firmware locally or via the network at any time. It
comes equipped with remote management capabilities, configurable signaling to
work with PBX, KTS, and/or telephone. The TVP-224HR utilizes advanced VoIP
related technology. It includes various voice codecs and fax algorithms, echo
cancellation, Voice Activity Detection (VAD) , Comfort Noise Generation
(CNG) , and lost packet recovery algorithms.
1.2 Networking Protocols
The TVP-224HR supports several industry-standard networking protocols
required for voice communication. The following table describes these protocols.
Networking ProtocolDescription
Internet Protocol (IP) IP is a messaging protocol that addresses and sends packets
across the network. To enable IP protocol, the TVP-224HR
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-224HR to transfer voice
communications over an IP network. The TVP-224HR
employs ITU-T H.323 protocol for setting up calls with
one another.
TFTP allows you to transfer files over the network. The
TVP-224HR 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.
RTP is a standard for transporting real-time data over IP
network. The TVP-224HR uses RTP protocol to send
digitized and compressed voice packets.
1.3 Package Contents
The contents of your product should contain the following items:
• TVP-224HR VoIP Gateway Router 4 port desk top version
• 100-240V Power Adapter
• 9-pin straight through RS-232 cable

then release the button.
1.5 Rear Panel
The rear panel of the TVP-224HR 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
the rear panel.
4-port TVP-224HR Rear Panel
LAN / Console Ports
The TVP-224HR is equipped with an Ethernet interface with 10/100 Mbps autonegotiation, auto MDIX capability. The Ethernet interface port is located on the
rear panel. In addition to the Ethernet interface port, there is a 9-pin RS-232
interface port on the rear panel. Their functions are described below:

Mbps Ethernet network
9-pin RS-232 User Console Connecting the TVP-224HR to a VT-
100 terminal or terminal emulator for
configuring the TVP-224HR
Command Line Interface
The TVP-224HR has a built-in command line interface and provides users a Command
Line Interface (CLI). You can configure TVP-224HR by entering commands from the CLI.
You can access the CLI from a VT-100 terminal or terminal emulator connected to the RS232 port on the front panel or through a Telnet session.
2.1 Connection through Serial Port
The serial port of the TVP-224HR is fixed at the following settings:
Baud rate 19,200
Number of data bit 8
Parity check None
Number of stop bit 1
Flow control None
To access the TVP-224HR through the RS-232 serial port, follow the steps below:
1. Insert one end of the serial cable that came with the TVP-224HR into the 9-
pin RS-232 port (labeled User Console) on the front panel.
2. Insert the other end of the cable into your terminal’s serial port.
Configure the terminal so that settings for baud rate, number of data bit, parity
3.
check, number of stop bit and flow control capability exactly match TVP224HR’s serial interface. (Refer to you terminal documentation for more
information about setting up these features).
4. Press <Return> from the terminal.
5. When the empty HyperTerminal Screen appears type “123”
6. The TVP-224HR displays the following prompts on the terminal and you are
ready to access the CLI then.
Console>
