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 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
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.

Configuration Management Commands
The configuration management commands allow the user to set values for system
configuration parameters. In addition, it provides mechanisms to allow a user to
control when new parameter values are put in use.
The CLI maintains three areas where the parameters are stored:
y Temporary
y Active
y Non-volatile Storage (NVS)
When a set command is entered and processed, it changes the parameter value in
the Temporary area. This does not affect current operation of the TVP-221H,
which is using the values in the Active area. The config activate command moves
configuration data from the Temporary area to the Active area, where it can
actually be used. Thus a user can make multiple changes in the Temporary area
using set commands, then put them into use with a single config activate
command. (Note that the config activate command may only be used between
calls, and will usually tear down any in-progress calls when invoked.)
Configuration data in the Active area is only available while the TVP-221H
remains in operation. If the TVP-221H is reset, the Active area is reloaded from
the data stored in NVS. Data in the Active area may be saved to NVS by entering
the config store command.
For most of the H.323 parameter, settings won’t take effect until the TVP-221H
reset. To ensure the H.323 setting to take effect, it is recommended to reset the
TVP-221H after changing the settings using the set command.
In summary:

Use set commands to make configuration parameters changes in the
Temporary area

Use the config activate command to move the new values into the Active
area, available for use

Use the config store command to save the new Active values in NVS

Reset the TVP-221H after changing H.323 settings and storing the setting to
NVS.

config {activate|store|erase}
Use the activate command to manage the configuration data. A sequence of
set command is typically preceded by and/or followed by the config command
for the set command to become active.
Syntax description
activate

Move the configuration from temporary area to active area.

store

Store the active configuration data into non-volatile storage.

erase

Erase the configuration from non-volatile storage.

Chapter 3

Upgrading the TVP-221H

This chapter explains how to upgrade your TVP-221H when new revision
software becomes available. Upgrades may improve system functionality
or add new features to your TVP-221H.

The TVP-221H offers two operation modes. Under normal conditions, the TVP-221H
operates in regular operational mode. When software upgrade is required, the TVP221H may be operated in download mode. Under download mode, the CLI will
support limited commands allowing users to read new revision codes from a remote
TFTP server and write it to the built-in flash non-volatile storage.
The CLI under download differs from normal in the prompts and that it supports less
commands.

3.1

Entering Download Mode

To switch from normal operation mode to download mode, use the download CLI
command.
Console>download

Note: To be able to switch to download mode from Telnet session, the TFTP loader
on the TVP-221H must be version 3.00 or higher.
The TVP-221H will terminate all on-going calls, shut down itself, reset and enter
download mode. If you enter download mode from Telnet session. The Telnet session
will be terminated too. You need to connect to the TVP-221H from Telnet client again
to be able to access the CLI commands. Refer to Section Connection through Telnet in
Chapter 8 for detailed information on how to connect to TVP-221H from Telnet client.
Upon entering the download mode, the CLI will show the following prompt.

Destination ID

ATPM Hunt Group Table
Several destinations may be grouped together to form a hunt group. When an
incoming phone number matches the phone number of the hunt group, the TVP221H attempts to terminate the call at each of the destinations in the hunt group
one at a time until a call is successfully completed. Plan how destinations are to be
grouped and fill out the hunt table worksheet, then use the CLI command atpm
hadd hunt_group_id hunt_type dest_id … for each entry in the
worksheet to add it to the hunt group table. The hunt_group_id in the command
corresponds to the Hunt Group ID in the worksheet, the hunt_type corresponds to
the Hunt Type (1 or 2), the dest_id … corresponds to the List of Destination IDs.
You may alternatively use the web browser to add hunt groups to the hunt group
table.

ATPM Address Table
Each phone number to be recognized by the TVP-221H must have its first digits
match an entry in the address table. Fill out the address table worksheet and use
the CLI command

atpm aadd tel# min_digits max_digits hunt_group_id
prefix_strip_len [prefix#] to add each entry in the worksheet to the address
table. The tel# in the command corresponds to the Digits to Match in the
worksheet, the min_digits corresponds to the Min. # of Digits to Collect, the
max_digits corresponds to Max. # of Digits to Collect, the hunt_group_id
corresponds to the Hunt Group, the prefix_strip_len correspond to No. of Digits to
Strip and the prefix# corresponds to the Prefix String. You may alternatively use
the web browser to add telephone numbers to the address table.
