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

TANDBERG GatewayIntroduction

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.

The TANDBERG Gateway

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. Typically,
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.

Installation

Installation site preparations

• Make sure that the gateway is accessible and that all cables can be easily connected.

• For ventilation: Leave a space of at least 10cm (4 inches) behind the gateway’s rear panel and 10cm (4 inches)
in front of the front panel.

• The room in which you install the gateway should have an ambient temperature between 0oC and 35oC (32oF
and 95oF) and between 10% and 90% non-condensing relative humidity.

• Do not place heavy objects directly on top of the gateway.

• Do not place hot objects directly on top, or directly beneath the gateway.

• Use a grounded AC power outlet for the gateway.

• You will need a CSU (Channel Service Unit) between your system and the PRI line from your network provider.

Rack Mounting (optional)

The gateway comes with brackets for mounting in standard 19” racks.

1. Disconnect the AC power cable.

2. Make sure that the mounting space is according to the ‘Installation site preparations’ (see above).

3. Attach the brackets to the gateway on both sides of the unit.

4. Insert the gateway into a 19” rack, and secure with screws in the front (four screws).

BEFORE STARTING THE RACK MOUNTING, PLEASE MAKE SURE THE TANDBERG GW IS PLACED SECURELY ON A HARD, FLAT SURFACE.

NOTE

TANDBERG GatewayInstallation

Connecting cables

Power cable

Connect the system power cable to an electrical distribution socket.

ISDN PRI cables

For each of the four PRI interfaces, the E1/T1 cable should be connected to a CSU (Channel Service Unit). You will
need a CSU between your gateway and the PRI line from your network provider.

LAN cable

To use the gateway on IP, connect a LAN cable from the ‘LAN 1’ connector on the gateway to your network. The
LAN 2’ connector is not used and should be left open.

RS 232 cable

To control the gateway using the dataport, connect an RS 232 cable between the gateway’s RS 232 connector
and the COM-port on a PC. For further information, please refer to the ‘Dataport’ chapter in ‘Configure the
Gateway’.

Installation

Gateway Configuration

The gateway requires some basic configurations before it can be used. It will be necessary to find the IP-address
and program the ISDN-PRI Line numbers.

To do this configuration, follow the instructions below:

1. Connect the RS232 cable between the gateway and a PC and then switch on the gateway.

2. Start a terminal program on the PC and configure it to: 9600, 8, 1, None.

3a. To assign a static IP-address, type ‘ipassign static’ and ‘ipaddress 1 static <IP-address>’.

3b. To assign an IP Subnetmask, type ‘ipaddress 1 subnetmask <subnetmask>’.

3c. To assign an IP Gateway address, type ‘ipaddress 1 gateway <gateway IP-address>’.

4. Restart the gateway.

5. Start a WEB browser and enter the IP-address of the gateway. Default password: ‘TANDBERG’.

6. To configure the gateway for ISDN dial in, enter PRI numbers and dial in number(s). For details, see

the ‘PRI Configuration’ and the ‘ISDN Dial in Configuration’ section.

7. To configure the gateway for IP dial in, register the gateway to a gatekeeper and enter H.323
services. For details, see the ‘H.323 Services’ and ‘H.323 Configuration’ sections.

TIP

DHCP ASSIGNED IP-ADDRESSES ARE SUPPORTED BY THE TANDBERG GATEWAY (FACTO RY DEFAULT).

TANDBERG GatewayInstallation

GW

Accessing the gateway

You may access the gateway by entering the IP-address of the gateway in a standard WEB-browser. You will
then be asked to enter a password. It is not necessary to enter ‘User Name’. The default password for the
gateway is ‘TANDBERG’. Remember that the password is case sensitive.

IF YOU DO NOT KNOW THE IP-ADDRESS, PLEASE FOLLOW THE

PROCEDURE IN ‘INSTALLATION’, ‘SYSTEM CONFIGURATION’.

TIP

THE PASSWORD CAN BE CHANGED IN ‘SYSTEM CONFIGURATION’,
‘MISC’. SEE ALSO THE ‘CONFIGURE MISCELLANEOUS PARAMETERS’

SECTION IN ‘CONFIGURE THE GATEWAY’.

TIP

Gateway start-up

To start the gateway, please make sure that the power cable is connected, and press the power switch button
to ‘1’.
