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.

1.2Networking 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 enables the TVP-221H to transfer voice

(VoIP)

communications over an IP network. The TVP-221H

 

employs ITU-T H.323 protocol for setting up calls with

 

one another.

Trivial File Transfer

TFTP allows you to transfer files over the network. The

Protocol (TFTP)

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 is a standard for transporting real-time data over IP

(RTP)

network. The TVP-221H uses RTP protocol to send

 

digitized and compressed voice packets.
