Chapter 1

Overview

This chapter gives an overview of the 4 ports desktop version VoIP Gateway (TVP-
224HR) 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 Protocol

Description

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)

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.

Trivial File Transfer
Protocol (TFTP)

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.

Real-Time Transport
(RTP)

RTP is a standard for transporting real-time data over IP
network. The TVP-224HR uses RTP protocol to send
