Chapter 1
Overview
This chapter gives an overview of the 4 ports desktop version VoIP Gateway (TVP-221H)
and a detailed description of its front panel and rear panel.
1.1 Features
The TVP-221H is a cost-effective and highly reliable analog Voice over IP (VoIP)
Gateway 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-221H 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-221H 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-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)
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.
Trivial File Transfer
Protocol (TFTP)
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.
Real-Time Transport
(RTP)
RTP is a standard for transporting real-time data over IP
network. The TVP-221H uses RTP protocol to send
digitized and compressed voice packets.
