Operator Safety Summary

For your protection, please read these safety instructions completely before operating the equipment and keep this manual for future reference. The information in this summary is intended for operators. Carefully observe all warnings, precautions and instructions both

on the apparatus and in the operating instructions.

Equipment Markings

The lightning flash symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltages” within the product’s enclosure that may be of sufficient magnitude to constitue a risk of electrical shock.

The exclamation mark within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions within literature accompanying the equipment.

Warnings

Water and moisture - Do not operate the equipment under or near water - for example near a bathtub, kitchen sink, or laundry tub, in a wet basement, near a swimming pool or in areas with high humidity.

Cleaning - Unplug the apparatus from the wall outlet before cleaning or polishing. Do not use liquid cleaners or aerosol cleaners. Use a lint-free cloth lightly moistened with water for cleaning the exterior of the apparatus.

Ventilation - Do not block any of the ventilation openings of the apparatus. Install in accordance with the installation instructions. Never cover the slots and openings with a cloth or other material. Never install the apparatus near heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

Grounding or Polarization - Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or third prong is provided for your

safety. If the provided plug does not fit into your outlet, consult an electrician. Power-Cord Protection - Route the power cord so as to avoid it being walked on or pinched by items placed upon or against it, paying particular

attention to the plugs, receptacles, and the point where the cord exits from the apparatus.

Attachments - Only use attachments as recommended by the manufacturer.

Accessories - Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the

apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

Lightning - Unplug this apparatus during lightning storms or when unused for long periods of time.

ISDN cables - CAUTION - To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.

Servicing - Do not attempt to service the apparatus yourself as opening or removing covers may expose you to

dangerous voltages or other hazards, and will void the warranty. Refer all servicing to qualified service personnel.

Damaged Equipment - Unplug the apparatus from the outlet and refer servicing to qualified personnel under the following conditions:

When the power cord or plug is damaged or frayed If liquid has been spilled or objects have fallen into the apparatus If the apparatus has been exposed to rain or moisture If the apparatus has been subjected to excessive shock by being dropped, or the cabinet has been damaged If the apparatus fails to operate in accordance with the operating instructions

T ANDBERG Gateway

Introduction

The T ANDBERG Gateway enables sites on IP and sites on ISDN to p articipate in meetings with each other with the quality and reliability found in all T ANDBERG equipment.

IP Services and Procedures

• Service Prefix.

• Dial Parameters. Ne w Integrated ExpresswayTM firewall traversal technology . Ne w H.235 Authentication at Gatekeeper and Border Controller . Ne w Alternate Gatekeeper - Increased network reliability .

ISDN Services

The T ANDBERG Gateway offers a variety of ISDN dial-in services:

• Direct Inward Dialing (DID) - The destination endpoint is determined from the dialed ISDN number .

• Interactive Voice Response (IVR) - The destination endpoint can be selected via touch tones.

• T erminal Control Session 4 (TCS-4) - The destination end point can be selected by endpoint signaling.

• Hotline/Operator Mode - The destination endpoint is a fixed one. Ne w T elephone Dial-Ins can be disabled. Ne w T wo number 2x64k ISDN Dial-in - Best interoperability with legacy equipment.

Security

• Secure Conference Ne w Flexible encryption configuration - Transparent or independent.

• Secure Access - support XML/SOAP over HTTPS, Web (HTTP) encrypted password and the services that

can be disabled.

- using standard based AES 128 and DES encryption on IP and ISDN.

T ANDBERG Gateway

Video Quality

• Natural VideoTF which provides 60 fields per second true interlaced picture.

T ANDBERG Gateway

Management Interfaces

SOAP Simple Object Access Protocol is a lightweight protocol for exchange of information in a decentralized,

distributed environment

X M L Extensible Markup Language is a flexible way to create common information formats and share both the

format and the data on the World Wide Web, intranets, and elsewhere. This functionality can be used by management systems like the T ANDBERG Management Suite to control the gateway .

HTTP Web-interface for system management, call management such as call transfer, diagnostics and

software uploads.

HTTPS Hypertext Transfer Protocol over Secure Socket Layer is a Web protocol that encrypts and decrypts

user page requests as well as the pages that are returned by the Web server . It uses Secure Socket Layer (SSL) as a sublayer under its regular HTTP application layering. HTTPS uses port 443 instead of HTTP port 80 in its interactions with the lower layer , TCP/IP. SSL uses a 40-bit key size for the RC4 stream encryption algorithm, which is considered an adequate degree of encryption for commercial exchange.

Network and Features

• Up to 8 video sites and 8 telephony calls can be held at the same time.

• Call rate of up to 2 Mbps for each call is supported through the gateway .

• A maximum of 4 Mbps (2 Mbps standard) ISDN bandwidth is supported through the gateway.

• Downspeeding

- Optimizes the end-to-end bandwidth automatically for the available network condition.

• Full H.243 Multipoint Control Unit (MCU) transparency , for seamless MCU connection through the gateway .

• Intelligent Packet Loss Recovery (IPLR).

• Far End Camera Control.

• T ext Chat (T.140).

T ANDBERG GatewayIntroduction

The T ANDBERG Gateway

Front view

The front of the gateway contains 24 Light Emitting Diodes (LEDs) organized in three groups. These diodes provide information about PRI-line status, LAN (Ethernet) connection and power.

Red Alarm or Loss of signal (LOS) indicates that there is no signal and thus no framing info received. The same effect will be obtained by pulling out the PRI cable. This may also be caused by a broken connector in the receive (RX) part of the cable.

Yellow Alarm or Remote Alarm Indicator (RAI) means that the gateway is receiving framing info, but in this framing info the other side tells the gateway that it is not reading the gateway’s transmitted framing info. T ypically, this may be a broken connector in the transmit (TX) part of the PRI cable. This could also indicate weak or noisy signal in the transmit (TX) part of the PRI cable.

T ANDBERG Gateway

Introduction

Rear view

The back panel provides four PRI interfaces, two LAN interfaces and one RS 232 interface located together with the power switch/connector and four cooling fans.
