1. Introduction
The TANDBERG 8000 is truly a combination of aesthetics and superior technology using two
wide screen 50” plasma monitors. It is a videoconferencing system designed for use with
network rates from 56 kbps up to 2 Mbps, using ITU-T H.320 standards for video compression
and a combination of H.221 and BONDING for communication on up to 30 ISDN B-channels.
The system also support calls up to 3 Mbps when connected to a LAN, using the ITU-T H.323
standard. All features of the TANDBERG 8000 are based on standards set by the ITU-T.
• When directly connected to BRI ISDN networks, TANDBERG's SoftMux enables
BONDING calls up to 768 kbps.
• When directly connected to PRI ISDN networks, TANDBERG's SoftMux enables
BONDING calls up to 2 Mbps.
• When directly connected to special data networks, TANDBERG's network manager
enables automatic detection of speeds up to 2 Mbps.
• When directly connected to a Local Area Network, TANDBERG's network manager
enables automatic detection of speeds up to 3 Mbps.
If the system is connected to both ISDN and LAN the TANDBERG 8000 can handle both ISDN
sites and IP sites in the same call.

2. Product Description
2.1 Codec
The Codec1 is the "brain" of the system and handles all incoming and outgoing video, audio and
data towards the switched public telephone networks, Local Area Networks (LAN) or external
networks.
The Codec receives pictures from a video source e.g. the TANDBERG Camera, encodes and
compresses the live video and audio at rates of up to 30 frames per second (60 fields per
second). The coded image and audio is transmitted to a remote unit at rates up to 768 kbps
(ISDN BRI), 2 Mbps (ISDN PRI/IP networks/External networks) or 3 Mbps (IP networks).
The Codec also receives incoming video
and audio at rates up to 3 Mbps, decodes the
live video and audio and passes the video
signal to the monitor for display. Audio is
decoded and passed to the TANDBERG
Natural Audio module.
2.1.1 Software Versions
There is one software version for TANDBERG 8000; available in either PAL or NTSC. The
software allows for calls up to:
• 768 kbps on ISDN BRI

2.2 Wide Angle View (W.A.V.E.) Camera
The TANDBERG 8000 is equipped with the W.A.V.E. Camera,
which is controlled by the remote control. This allows the user to
zoom, focus, pan and tilt the camera. The camera is either PAL or
NTSC depending on the country of use.
The power on the codec must be switched off whenever connecting/disconnecting a camera
to/from the codec or a ‘daisy chain’3. Only cameras with software revision TT0a or later support
camera tracking and daisy chaining.

• The system is able to store up to 15 pre-set camera positions, making it easier for the user to
change the selected view rapidly during a presentation or a meeting. If the main camera is
selected, pan, tilt, zoom and focus will also be stored with the preset. The first 10 presets may
be accessed via the remote control, while the 5 remaining presets are accessed by data port
commands or IR-codes (e.g. by using the TANDBERG Tracker4).
• The camera is equipped with a wide angle lens and covers a wide area as shown below:
The camera covers a horizontal field of view of 77°, while panning takes the range up close
5
to 270°
• Minimum horizontal field of view (maximum zoom in) is 7.7°.
• The camera covers a vertical field of view of 61°, while tilting takes the range up to 96°.
• Tilting the camera max. 15° upward and max. 20° downward.
• Automatic or manual brightness, focus and white balance ensures that the user obtains the
best possible picture.

2.2.3 Multiple Camera Control
The TANDBERG 8000 is able to control up to four W.A.V.E. cameras from the remote control.
The Main Camera must be connected to data port 2 on the Codec. The other cameras must be
daisy-chained to the Main Camera. The Codec will provide power for the Main Camera only.
The other cameras each need a separate power supply. The Main Camera must be connected to
Video Input 1; the second camera must be connected to Video Input 2 and so on.
The codec will automatically detect the number of cameras and the camera ID can be read in the
‘System self test’ menu. The maximum length of the camera cable for multiple cameras
supported by TANDBERG is 20 m (65 ft).
The figure below is an example of how multiple cameras should be connected:
2.2.4 Camera Tracking
Voice-activated camera tracking with noise suppression and preset-combination has been
implemented in the TANDBERG 8000 software. A W.A.V.E. Camera connected to Video Input
1 can be used for camera tracking6. Two or three microphones must be installed and each
microphone must be associated with a camera-preset position (preset P7 to Mic1, P8 to Mic2
and/or P9 to Mic3). Camera tracking is temporarily turned off when another video source is
selected (e.g. a document camera) or when the camera is manually adjusted.
6
If more than one W.A.V.E. camera is connected to the system, the presets may also be put on these cameras.
D12008 Rev. 11 10
Technical Description of TANDBERG 8000 with software version E3/B8
2.2.5 Calculation of Horizontal Viewing Area
The W.A.V.E. Camera’s viewing area is maximized when the camera is zoomed fully out and
minimized when the camera is zoomed fully in. To calculate the viewing area, the following
measurements need to be taken:
Camera
Horizontal
Viewing Area B
Distance A
The maximum viewing area for the W.A.V.E. camera, with the camera zoomed fully out is
calculated by the formula:
(Distance) A x 1.6 = (Max. viewing width) B
max
E.g. If A is 5 meters then the width of the viewing area B will be 5 x 1.6 = 8.0 meters
The minimum viewing area for the W.A.V.E. camera, with the camera zoomed fully in is
calculated by the formula:
(Distance) A x 0.13 = (Min. viewing width) B
min
E.g. If A is 5 meters then the width of the viewing area B will be 5 x 0.13 = 0.65 meters
2.2.6 Camera Control Interface
The control cable for the camera must be connected to Data port 2. When the Codec is powered
up, Data port 2 will automatically detect if a camera is attached to it.
The TANDBERG 8000 supports two different camera protocols, the TANDBERG camera
protocol and the VISCA protocol. To control the W.A.V.E. Camera, the following parameters
are required on Data port 2:
• 9600 Baud
• 8 data bits
• 1 stop bit
• No parity
• Auto or VISCA
TANDBERG 8000 also supports:
• Cameras such as Sony EVI D30/31 using the Sony VISCA protocol.
The camera type in use will be automatically detected in the system boot-sequence except
cameras using the VISCA protocol, where this option must be selected in the data port menu.
D12008 Rev. 11 11
Technical Description of TANDBERG 8000 with software version E3/B8
2.3 Remote Control
2.3.1 Transmission Protocol
The Infra Red (IR) sensor for the remote control is located in front of
the W.A.V.E. Camera, just below the front glass. There is also a
second IR-sensor located in the front of the Codec itself, which will
be automatically enabled if the W.A.V.E. Camera is not connected to
Data port 2. The TANDBERG handheld remote control transmits IRsignals using the following parameters:
Protocol Siemens SDA2208
Reference Freq. 485 kHz
Address 4 & 7
IR wavelength 940 nm
IR carrier Freq. 30 kHz
2.3.2 Key Pad Layout and Codes
The hand held remote control transmits 46 different codes. The
keypad will not transmit additional codes if more than one key is
pressed simultaneously.
The following table shows relationship between the remote’s buttons
and their respective codes.

3. Operation and User Interface
The TANDBERG 8000 is normally operated via a hand-held, infrared
remote control. TANDBERG 8000's simple and concise multi-coloured
on-screen menu ensures that the user will be guided directly to the option
or the feature required. The menu system is cursor driven and easy to use.
With the intelligent on-screen user feedback the system always ensures the
relevant information is given to the user. (E.g. if a channel is lost, the user
will see on-screen text message ‘please wait, re-establishing the call’).
The Quick Keys (located on the top of the remote) relate to the three
blocks
at the bottom of the screen. The text on these blocks will change depending
on which menu is selected.
The user will hear a key tone when entering letters and digits via the
remote control. The key tones may be turned off via the system’s data port
if desired.
The TANDBERG 8000 can also be controlled via the data port of the
Codec by using a comprehensive set of data port commands10. This
enables the Codec to be controlled by a different user interface, such as an
AMX or Crestron system.
The web browser can be used as another interface to the TANDBERG
8000. By connecting the codec to a LAN, the codec may be accessed from
a PC located on the same LAN or WAN; allowing the codec’s features to
be controlled remotely via the web interface.
For information on how to operate the system, please see the
‘TANDBERG 8000 User Manual’ supplied with the system.

4. Codec Interfaces
Extensive use of industry standard interfaces and connectors ensure effortless integration of
external equipment with the TANDBERG 8000. These interfaces can easily be controlled via
one of the intuitive user interfaces. The TANDBERG 6000 codec is used in the TANDBERG
8000 system.

4.1.1 PRI E1/T1 ISDN & Leased Line E1/T1 Interface
The main RJ-45 jack supports bit rates from 56 kpbs up to 2 Mbps (1.5 Mbps PRI/T1) and may
be used as a PRI E1/T1 interface or a Leased Line E1/T1 interface. Port number 2 is designed
for cascading features when PRI is used.
4.1.1.1 PRI E1/T1 ISDN
Both the Intelligent Call Management (ch. 4.1.6) and the call status are implemented for PRI.
The PRI interface may require an external CSU depending on the network layout. ‘Cable
Length’ in the PRI set-up menu specifies the distance from the Codec to the CSU or last
repeater.
A CSU should not be required if the system is within 200 m (655 ft) of the last repeater
depending on the PRI cable quality.
The TANDBERG 8000 supports the PRI protocols AT&T Custom, National ISDN and ETSI
(Euro ISDN). Within these protocols the following switches are supported:
Switches Protocols supported
4ESS (AT&T) AT&T Custom
5ESS (AT&T) AT&T Custom and National ISDN11
DMS250 (Nortel) National ISDN
DMS100 (Nortel) National ISDN
(any switch) ETSI (Euro ISDN)
When booting up with PRI selected, the boot-up text will display ‘Waiting for network
activation’. The boot-up text will not be removed until the PRI line is active or a remote control
button is pressed.
Several TANDBERG 8000 (i.e. 6000 codecs) can be connected to the second PRI port on the
TANDBERG 8000 by cascading. Calling systems on the same PRI port is easily done through
MSN.
Channel hunting is provided for outgoing calls, this feature is normally used when the number
of channels needs to be specified and when a National ISDN PRI is used with a nonTANDBERG PRI unit in the cascading chain. The channels outside low and high can then be
reserved by other devices. When no value is specified for low or high channel, they default to 1
(low), 23 (high US) and 30 (high Europe). Default search is from high to low.

Description of PRI Alarms
A PRI cable consists of four wires (two pairs of wires): One pair for Transmit (TX) and one pair
for Receive (RX) signals.
Red Alarm
Red alarm or Loss of signal (LOS) means that there is no signal and thus no framing info
received. (This has same effect as pulling out the PRI cable).
Yellow Alarm
Yellow alarm or Remote Alarm Indicator (RAI) means that the TANDBERG system is receiving
framing info, but in this framing info the other side tells the system that it is not reading the
system’s transmitted framing info. Typically, this may be a broken connector in the TX part of
the system PRI cable. This could also indicate weak or noisy signal in the TX part of the system
PRI cable.
Blue Alarm
Blue alarm means that network on the far side of the CSU is unavailable.
Scenario: TANDBERG codec is connected via a CSU (i.e. a NT ‘Network Termination’) as
follows:
Codec–cableA–CSU–cableB–Network
If a CSU loses framing/sync from the network (example: a bad cable B), it shall no longer send
valid framing out on cable A towards the codec. Instead it transmits "Blue Alarm". Seen from a
codec receiving blue alarm, this means that the network on the far side of the CSU is
unavailable.
4.1.1.2 Leased Line E1/T1
The TANDBERG 8000 has implemented the G.703 ITU standard as a network interfaceLeased Line E1/T1.
When connected to a Leased Line E1 network it is possible to run calls from 64 kbps up to 2
Mbps. When connected to a Leased Line T1 network from 56 kbps up to 1.5 Mbps.
There are two Call Control setting for the Leased Line T1/E1:
• Manual dial mode is supported on Leased Line E1/T1 (i.e. The green ‘connect’ button must
be pressed to initiate a leased line E1/T1 call).
• The Auto mode is supported on the Leased Line T1/E1. This allows the systems to
automatically answer an incoming call.

4.1.2 BRI ISDN Interface
TANDBERG 8000 is supplied with the following BRI ISDN Protocols13:
• Euro-ISDN (ETSI)
• Japan/Taiwan ISDN
• National ISDN
• AT&T custom
• Fetex ISDN
Pinout of S/T Interface:14
4.1.2.1 ISDN Subaddress & MSN
Subaddress:
It is possible to set a subaddress on the TANDBERG system when more than one system
share ISDN lines (must be ordered from ISDN provider). Dialing from a TANDBERG
system using subaddressing, is achieved by adding a star plus the subaddress at the end
of the ISDN number.
E.g., If ISDN number is 67117777 and the subaddress is 123, the number to dial into this
system will be: 67117777*123
Incoming calls without subaddress will be handled by all units on that ISDN line (i.e. all
systems would ring). For incoming calls with subaddress, only the unit with matching
subaddress will accept the call.
MSN:
Multiple Subscriber Number is also implemented in the TANDBERG system. If MSN is
set to ON, the system will only accept incoming calls to the ISDN numbers programmed
in the ISDN settings menu.

4.1.3 Ethernet / LAN Interface (H.323)15
The RJ-45 jack for the Ethernet interface (manual or automatic detection of 10/100Mb) supports
bit rates from 64 kbps up to 3 Mbps. The ITU-T standard H.323 v4 protocol is implemented in
the TANDBERG 8000.
The following features are specifically relevant for this network interface16:
4.1.3.1 Default IP Password
New systems or systems that have loaded factory defaults will have a default password
“TANDBERG” all caps and the strict password enabled.
Strict password: IP password that is at least 8 characters long and contains both letter and
Numbers (alphanumeric). When off all IP password are accepted including blank ones.
Command is: “strictpassword <on/off>” Default is on. The strict password needs to be disabled,
via Data Port or Telnet to set a blank or simple password.
4.1.3.2 Quality of Service features (QoS)
4.1.3.2.1 IP precedence
IP precedence is a classification of packets from 0 (low priority) to 7 (high priority). The
values 6 and 7 are typically reserved for congestion control. IP precedence helps a router
select what kind of traffic to prioritise. By means of queue mechanisms, it can select
which packets to send first and which to throw away. Some information/traffic is time
critical while other is not, and classification is used to differentiate this traffic.
One may set separate IP precedence for Signalling, Audio, Video and Data (values 1 – 7)
as well as turn IP precedence off.
The auto setting uses the following values for IP precedence:
Signalling=6
Audio/Video=4
Data=3 (e.g. FECC commands)
This means that in auto, IP precedence has the value 6 (i.e. signalling value) while both
audio and video value is 4; data value is 3. Setting the IP precedence value in system’s
menu is actually setting the signalling value. The audio/video and data values are
changed accordingly in respect to the signalling value (i.e. audio/video value = - 2; data
value = - 3).
4.1.3.2.2 Diffserv
Diffserv is an extension of IP precedence, where one can set values from 0 to 63
(63=Highest priority).
