Introduction

Outline

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.

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

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.

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.
