Important Safety Instructions

When handling or using the VoIP-TA unit, the following safety precautions should
be observed to prevent injury and/or damage to the unit. Use of this equipment in
a manner other than that specified in this and other VoIP-TA documents will void
the product warranty and may result in damage, serious injury or death.

WARNING Incorrect use by neglecting the following instructions

may cause fire, electric shock, unit failure, resulting in
damage, serious injury or death.

• Do not connect a commercial power supply circuit, analogue, digital
(ISDN) or PBX digital telephone line to the LAN or PC port.

• Do not use with power supply voltages other than those specified.

• Do not insert or drop metal objects into any of the openings.

• Do not disassemble or modify this product in any way.

• Do not place any vases, cups, cosmetics, chemicals, pots or any other

containers containing liquids or small metal objects, near the product.
Spillages into the product may cause fire, electric shock or unit failure.

• Do not try to connect or disconnect the power plug with wet hands.

• Insert the power plug fully and securely into the power outlet. To avoid

electric shock, do not use a plug that exposes the terminals when
inserted.

• Avoid star connections as fire or overheating may result.

• Do not put heavy objects on the AC adapter cord or expose it to

excessive heat.

• Do not pull the cord or allow it to overheat as it may be damaged and
could cause fire or electric shock.

• If lightning strikes a neighboring area, stop operating the product by
disconnecting the AC plug (by grasping the power plug, not the cord)
from the power supply outlet.

Introduction

Welcome to the world of Oki Internet telephony…

The Oki voice over IP (Internet Protocol) telephony adapter, VoIP-TA, is a
self-contained H.323 version 2 compliant communications device that
allows organizations to route both voice and facsimile communications
over any TCP/IP network.

The VoIP-TA is designed to provide a service that is virtually
indistinguishable from that of conventional telephone and facsimile
services.

Use this guide to familiarize yourself with the VoIP-TA. Should you need
to handle the equipment, pay special attention to the procedures and
safety precautions contained in this guide.

The VoIP-TA

The VoIP-TA is a one-channel Internet telephony adapter that provides
Internet telephony services conforming to industry standard H.323
version 2 specifications. It can be connected to a conventional analogue
telephone or G3 facsimile machine.

Once installed, VoIP-TA units use the Internet Protocol (IP) network to
bridge the distance between units at a fraction of the cost associated with
conventional telephony methods.

* Gatekeeper is necessary when more than 100 IP addresses are to be used.

Features

• Compact size and one-channel Internet telephony adapter.

• Automatic telephone routing by specified telephone numbers.

• A PC connection port is provided however, the VoIP-TA cannot

communicate with a PC connected to the PC port.

• Smooth and natural telephone calls by optimizing the voice buffer.

• Supports Dynamic Host Configuration Protocol (DHCP manual

allocation) for local IP addresses.

• Conforms to the ITU-T recommended H.323 version 2 specifications.

• Supplies real-time Internet facsimile communication that conforms to

the ITU-T recommended T.38.

• Uses high quality voice compression technology.
Conforms to ITU-T G.729A (8 kbps), G.723.1 (5.3/6.3 kbps), and G.711

(µ-law/A-law). [Automatic selection or fixed]

The Public Switched Telephone Network (PSTN) is supported by VoIP-TA version

Note

1.2 and later. The version number is clearly marked on the bottom of the unit.To

avoid incorrect use contact your authorized sales agent or service office if in doubt.

VoIP-TA conforms to the lower of the two. When either the PC or LAN port is 10
BASE-T, both ports are set to 10 BASE-T communication. If a PC is connected to the
PC port during a call, the call may be interrupted for approximately one second.
Please avoid such usage.

Connections

Installation

Place the main unit in a vertical position as placing it horizontally could
shorten the life of the unit.

The following illustration shows where equipment should be connected
to the ports at the rear of the VoIP-TA unit.

Analogue telephone or G3 facsimile equipment

Connect an analogue telephone or G3 facsimile machine to the TEL
connector of the VoIP-TA unit via a telephone cord.

To make facsimile connections, the other end terminal equipment should
be compliant with the ITU-T T.38 standard.

Analogue PSTN

Connect an analogue PSTN line to the LINE port at the rear of the VoIP-TA
unit via a telephone cord.

Installation

5

Personal computer (PC)

Connect a PC connector to the PC port at the back of the VoIP-TA unit
using an unshielded twisted pair (UTP) straight cable
If both a PC and LAN are to use 100BASE-TX communications, use
category 5 [max. 100m].

It is recommended that only one PC is connected to avoid voice deterioration.

Note

(categories 3 to 5).

LAN

Connect the LAN connector to the LAN port at the back of the
VoIP-TA unit via a cross cable (UTP categories 3 to 5). If connecting to a
hub, use a straight cable.

If the LAN is connected by 100BASE-TX and the PC is connected by
100BASE-TX, or if the PC is not connected, use a category 5 cable
[max. 100 m].

CONSOLE (setting up the VoIP-TA with a PC)

Connect the PC for setup on the VoIP-TA by using the serial cable RS­232C (9 pin – 9 pin straight) to the CONSOLE port.

FG (grounding)

After connecting the frame ground (FG) cable to the FG port at the back
of the VoIP-TA unit, connect the other end to a ground terminal in the
house or ground it separately.

6

Power source

Connect the supplied AC adapter to the DC IN 12V port at the back of the
VoIP-TA unit. Connect the attached AC adapter to a power outlet.

Installation

Cautions

During installation

• All cables used to connect the equipment must be accessories of the
equipment or suitable to fit the equipment.

• Make sure the AC power plug is disconnected from the power outlet
when connecting the FG cable to the unit.

• When an exchange machine, such as PBX or EKTS is connected to the
TEL port of VoIP-TA, the sound quality may deteriorate. Only one
exchange machine should therefore be relayed between the VoIP-TA unit
and telephones.

• Interference noise may occur during telephone calls in areas that receive
strong radio waves, such as near a broadcasting station or CB radio
transmission. If calls are affected in this way, consult your authorized
sales agent or service office.

• Do not install the VoIP-TA unit near equipment that generates
magnetism or radio waves such as TV sets, radios, radio machines,
microwave ovens, or inverter-type fluorescent lamps, as this may cause
the unit to malfunction.

During use

• Do not subject the unit to strong impact, such as dropping the unit.

• Do not force cables to connect or disconnect as this may result in faults.

The connector and port should join with reasonable ease.

• When cleaning the exterior of the VoIP-TA, turn it off and disconnect the
unit (by pulling the power plug, not the cord), wipe it with a water damp
cloth and wipe it dry with a soft dry cloth. Do not use volatile thinner,
alcohol or a silicon cleaner under any circumstances as it may result in
damage, discoloration or deformation.

Placing Calls

Via an IP Network

Placing and receiving calls with the VoIP-TA unit are usually quite simple
and performed in the same way as conventional telephone networks. In
some cases however, the phone numbers to be used, may differ slightly
from the ones you used previously.

General Operation

Outgoing calls

Use a telephone that generates a Dual Tone Multiple Frequency (DTMF)
signal. Pick up the handset and dial a remote party’s telephone number.

Incoming call response

An incoming tone will be emitted from the telephone.

Disconnection

A telephone call can be disconnected by hanging up the handset onto the
telephone receiver.
