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

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.

If more than one W.A.V.E. camera is connected to the system, the presets may also be put on these cameras.

Page 11

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.

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.

2.5 Stand

TANDBERG 8000 stand consists of the Base and the Monitor Rack, both with a removable rear panel8.

The Natural Audio Module and the Codec are located inside the base. The Codec’s connections are easily accessible once the front door of the Base has been opened.

To place the monitor(s) inside the Monitor Rack, the large one-piece plastic front-cover must be opened.

The cables that need to go out from the system (e.g. ISDN cables, power cables) can be routed through a hole at the back of the Base. To install/add cables going out of the system through this hole, the rear panel of the Base needs to be opened.

2.6 TANDBERG Natural Audio Module (NAM II)

The NAM II is a specially designed TANDBERG audio module that provides the user with unique audio qualities.

The Natural Audio Module II consists of the following:

Three way active speaker system with active crossover

• 2 x 130mm bass speaker elements

• 1 x 25mm tweeter

Audio amplifier9: 3 x 50 Watts

The Natural Audio Module is placed inside the Base of the system.

To remove the rear panel(s), a phillips/starshaped screwdriver is needed.

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.

Please, refer to ‘TANDBERG API – (Dataport User Guide)’ (D11943)

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.

Dependent on the configuration of the switch

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).

For further info on H.323, please refer to document ‘TANDBERG and IP’ (D12434)

NOTE: E3/B8 software does not support T.120 when running H.323 calls

D12008 Rev. 11 21

Page 22

Technical Description of TANDBERG 8000 with software version E3/B8

4.1.3.2.3 IP type of service (TOS)

TOS helps a router select a routing path when multiple paths are available.

Delay- tells router to minimize delay

Throughput- tells router to maximize throughput

Reliability- tells router to maximize reliability

Cost- tells router to minimize cost

Off- Turns TOS off

4.1.3.2.4 Resource-Reservation Protocol (RSVP)

RSVP is a protocol that allows the TANDBERG system to request the network to reserve the bandwidth needed for the IP call.

4.1.3.3 Automatic selection of H.323 or H.320 outgoing calls

• IP address or E.164 number dialling.

• Automatic selection based on network address type or predefined prefixes.

4.1.3.4 IP adaptive bandwidth management

• The codec never produces more traffic than needed, for better utilization of network

resources. Most of the data sent in a videoconference is video data. Thus, by incorporating smart video algorithms, the codec sends no more video data than necessary. Little movement in the picture gives low bit rate; while a lot of movement gives higher bit rate.

• The codec regulates outgoing and incoming media bit rates by means of flow control

signalling. An example of this is automatic adjustment of total bandwidth used when sites are added in a MultiSite call or when DuoVideo is added.

4.1.3.5 Gatekeeper authentication

When set to auto, this feature automatically locates a gatekeeper on the same subnet and registers the system using the E.164 alias.

If the gatekeeper supports alternate gatekeepers, the TANDBERG system will receive a primary and secondary gatekeeper address. If the primary gatekeeper fails, the system will register to the secondary gatekeeper that was declared by the primary gatekeeper.

Re-registration at the gatekeeper will occur regularly and automatically.

4.1.3.6 Registration to Call Manager

The TANDBERG systems support registration to a CallManager. It is only possible to register the TANDBERG system to a CallManager when the gatekeeper registration is disabled, and the CallManager is configured with a H.323 client that matches the IP address and the E.164/phone number of the TANDBERG system. When the “Use Gatekeeper” is set to off, enable “Use CallManager” by setting it to On, and set the IP address of the CallManager in the ”CallManager IP” field. The endpoint will now register to the CallManger

alternate gatekeeper supported in the Cisco MCM Sw 12.2 gatekeeper

D12008 Rev. 11 22

Page 23

Technical Description of TANDBERG 8000 with software version E3/B8

The registration of a H.323 client in CallManager is supported on the CallManager (CCM) 4.0 software and forward.

Note: CallManager does not support features like Duo Video, H.264 and encryption. A TANDBERG endpoint registered to CallManager will loose these capabilities. There is no confirmation on the TANDBERG system that it is registered to a CallManager.

4.1.3.7 Configuring an H.323 client on the CallManager 4.0

To configure the CallManager with an H.323 client, log on to the administration web interface and go to the phone configuration page. The Phone configuration page is located on: device (top menu) -> Add a New device -> Phone -> H.323 Client. In the phone configuration page type the IP address of the TANDBERG system in the Device name field, select device pool and push the insert button. A pop-up box will now appear on the screen and ask you if you would like to configure the directory number. Push the ok button. You should now see the Directory Number Configuration WEB page. Enter the E.164/phone number of your TANDBERG system in the Directory number field, and in the “Forward and Pickup Settings” enter the time of “No Answer Ring Duration”. The time selected has to have a value from 1 to 300 seconds. Push the Add button to update the CallManager with the directory number settings. You have now configured the CallManager with a H.323 client and should be able to register the TANDBERG system to it.

When the TANDBERG system is registered to a CallManager, it will be possible to place and receive calls from this system to any other video and voice systems that are registered on the same CallManager.

4.1.3.8 H.323 ID

H.323 ID is a feature allowing text names instead of E.164 numbers to be dialled. The TANDBERG system will use the System Name as its H.323 ID. Even though one cannot dial out with an H.323 ID via the remote control one can use the web interface or the dataport. Other systems can also dial in using the H.323 ID.

4.1.3.9 Dynamic playout buffering

Shapes the incoming data for better playout and re-sequencing of packets delivered out of order. This ensures better lip sync.

4.1.3.10 Asymmetrical media capabilities

Audio and video protocols can be fully asymmetrical. E.g., the TANDBERG system can send H.263 and receive H.261 at the same time.

4.1.3.11 Diagnostic tools for IP

Q.931 To show Q.931 trace during a call you need to issue the command syslog on.

One can get traces for RAS, Q.931 and H.245 with this command. It is a complex trace and requires an extensive knowledge in H.323 signalling to be understood.

Ping Ping is used to see if the codec is able to reach a specific IP-address, using a

mechanism in IP called ICMP. If a codec is unable to register to its gatekeeper, or if it is unable to dial a specific endpoint, one can use ping to see if there is at least an IP-route to the gatekeeper or to the endpoint. In case you have problems,

D12008 Rev. 11 23

Page 24

Technical Description of TANDBERG 8000 with software version E3/B8

one would first ping the default gateway, then the gatekeeper, and then the other endpoint.

Traceroute Traceroute does exactly that; it traces the route an IP-packet takes to reach its

destination and displays all router hops. Traceroute is very useful for seeing exactly where there is a routing-problem in the IP-network, and for checking where transport-delay is introduced.

4.1.3.12 NAT support

Network Address Translation is implemented to support small/home office applications requiring a single endpoint behind a NAT router. NAT also supports the use of a gatekeeper outside the NAT router.

4.1.3.13 Latency & Jitter

Latency is defined as the time between a node sending a message and receipt of the message by another node. The TANDBERG systems can handle any value of latencyhowever, the higher the latency, the longer the delay in video and audio. This may lead to conferences with undesirable delays causing participants to interrupt and speak over each other.

Jitter is defined as the difference in latency. Where constant latency simply produces delays in audio and video, jitter can have a more adverse effect (e.g. the video may be ‘blocky’). Jitter causes packets to arrive out of order or at the wrong times, which again leads to packet loss. TANDBERG can manage packets with jitter up to 100ms. If excessive packet loss is detected, the TANDBERG systems will downspeed the connection until acceptable packet loss is achieved.

4.1.3.14 Layer 4 Ports used in H.323 calls

The layer 4 ports used by the system in a H.323 call can be defined as follows:

• Dynamic: The ports are allocated at random from 2048 to 65535.

• Static: Will use the predefinded layer 4 ports listed in the tables below.

Point-to-point + Duo Video

Function Port Type

Gatekeeper Discovery (RAS) 1719 UDP Q.931 Call Setup 1720 TCP H.245 Range 5555—5556 TCP Video Range 2326—2333 UDP Audio Range 2326—2333 UDP Data/FECC Range 2326—2333 UDP

D12008 Rev. 11 24

Page 25

Technical Description of TANDBERG 8000 with software version E3/B8

(*) Note: While using MultiSite, if a site is disconnected and reconnected without terminating the entire conference, the next site to be connected will have a H.245 port outside of the specified range. If this functionality is required through a firewall, the range of TCP ports can be extended past 5560. However, if a site is disconnected and reconnected, without ending the conference enough times one can quickly end up outside of this range again.

4.1.3.15 IP packet sizes

Audio

The system automatically selects the most favorable IP packet size for audio. Depending on the network conditions, the system will send 20 ms or 40 ms of audio in each packet, thus:

• G.711 – 160/320 bytes per packet

• G.728 – 40/80 bytes per packet

• G.722 – 160/320 bytes per packet

Video

The system is sending maximum 1450 bytes of video per packet.

Note:

In addition, the system needs to add the following header information for each of the audio and video packets above:

20 bytes IP-header, 8 bytes UDP-header and 12 bytes RTP-header (i.e. 40 bytes in total).

Packet loss:

Packet loss is displayed in percentage (%) in the Call Status menu of the system. The number shown is the average of audio- and video- packets that are lost during the last 2 seconds.

4.1.3.16 Intelligent Packet Loss Recovery (IPLR)

IPLR is an ITU standard based packet loss compensation for H.323 that improves received and transmitted video to/from the TANDBERG system. IPLR supports all video protocols and resolutions that TANDBERG systems already have implemented and is compatible with all terminals, Gateways and MCUs.

IPLR is a special algorithm developed at TANDBERG that will make efforts to reconstruct the lost packets and reduce the visual effects caused by packet losses.

In addition, IPLR will make transmitted data more resilient to lossy networks. IPLR transmission functionality can be disabled and re-enabled by a dataport command.18 It is enabled by default.

IPLR will automatically start when packet loss is detected on the H.323 network. (See also chapter on ‘IP downspeeding’)

4.1.3.17 IP Conflict Warning

The TANDBERG system automatically checks whether its IP address has been assigned to another system on the same IP network.

In case of double address assignment, the TANDBERG system will display an IP address conflict warning to the user.

Please, refer to ‘TANDBERG API – (Dataport User Guide)’ (D11943)

D12008 Rev. 11 25

Page 26

Technical Description of TANDBERG 8000 with software version E3/B8

Once a detected IP address conflict has been resolved, the TANDBERG system can be operated without reboot.

4.1.4 NET Interface

The NET interface provides several network protocols to be used with terminal adapters in special applications. The protocols supported are:

Network protocols

• V.35

• RS-449

• RS-530

• X.21

Dialling protocols/call control

• RS-366

• Leased line

• Data triggered

• Manual mode

The above protocols are used for connection to special equipment supporting networks such as:

• Switched 56/64 kbps

• Leased line 56/64 kbps

• X.21

• Leased line (dedicated) T1/PRI

• E1

• T1

• LAN

• ATM

• Circuit switched (dial up) T1/PRI

The different configurations are described in the document ‘Connecting external networks’ (D12096) and in special application notes available on the ‘TANDBERG Technical documentation’ CD-ROM or by contacting your TANDBERG representative.

A combination of External Network (V.35\RS449\RS366\X21\Leased Line T1/E1) and IP sites is possible under the following prerequisites:

• An External Network party must be connected first.

• No ISDN parties can be part of the conference.

4.1.5 Streaming19

TANDBERG 8000 supports streaming of H.261 video and G.711 (µ-law) audio both when the system is in a call or outside a call. When inside a call, audio from both sides is streamed together with the video from the site that is ‘on air’ (i.e. voice switched). It is also possible to force the video from either local or far end to be shown constantly.

The streaming video may be displayed on the codec’s web page. The streamed video/audio can be viewed on most free viewers, but TANDBERG recommends that Apple Quick Time is used.

• Streaming video rates available are: 16, 32, 64, 128, 192, 256 or 320 kbps.

• Streaming audio rate is fixed to 64 kbps.

The streaming format RTP (over UDP) is supported on the TANDBERG system.

For security purposes, streaming is disabled by default and may only be enabled from the main menu or the data port. However, start/stop and configurations can be set via web or telnet.

A Streaming password may be set in order to prevent unwanted users streaming from the system.

Streaming Chat:

When streaming is viewed from the systems web page, it is possible to send messages to the system. The messages are displayed on the system’s monitor.

4.1.5.1 Automatic announcement of Streaming

The TANDBERG 8000 can be used in a Cisco IP/TV environment. The system periodically transmits a Session Announcement Protocol (SAP) message to inform clients where the streaming can be found.

4.1.6 Intelligent Call Management (ICM)

By using TANDBERG's Intelligent Call Management (ICM), calls can be made from data rates of 56 kbps up to 2 Mbps via ISDN networks (3 Mbps on IP).

ICM is a highly sophisticated feature provided by the TANDBERG 8000 that makes the connection between two sites more reliable and safe. If the ISDN network drops channels during a call, the conference will not shut down but adjust to the remaining number of available channels20. This ability is called ‘Downspeeding’ and is in accordance to the BONDING Mode 1 standard.

Active streaming disables MultiSite and Duo Video. For further info on Streaming, please refer to the User Manual and the documents

‘TANDBERG on Streaming’ (D12408 and D11934) 20

Depending on the capability of the remote system to support downspeeding.

D12008 Rev. 11 27

Page 28

Technical Description of TANDBERG 8000 with software version E3/B8

ISDN Downspeeding will be started when one of the following actions occurs:

1. Fallback to 2xH221 call when no BONDING framing is found

2. Non-matching number of channels (N) during BONDING setup (e.g. N=4 on site A, N=6 on site B)

3. Downspeeding during call setup caused by a channel that won't connect

4. Disconnect and downspeed if a channel won't sync

5. Downspeeding when detecting B-channels that are looped

6. Downspeeding if a channel drops during the call

The TANDBERG system will also start the BONDING synchronization procedure if there is a long fatal failure situation:

7. Extended loss of H221 framing

8. Continuous BCH framing error in the video stream. If then a channel fails to sync, it will be disconnected (as mentioned in 4.)

‘Downspeeding’ on IP:

The TANDBERG system has a similar way of ‘downspeeding’ on IP, described as follows:

a) If system gets more than 10% packet loss during the last 2 seconds, it will go down 64

kbps. (Ex. Call set up on 768 kbps and the above packet loss occurs, the new callrate will be 768 kbps – 64 kbps = 704 kbps).

b) If after the next 2 seconds, there is still more than 10% packet loss, system will

‘downspeed’ 64 kbps again.

c) The above will happen until call rate of 192 kbps is reached. d) If still same packet loss at 192 kbps the system will ‘upspeed’ back to original call rate

(since when in this situation, one may assume that the packet loss is due to other reasons and not the H.323 call itself).

Different from the ISDN downspeeding, the system will not change Audio and Video algorithms during the ‘downspeeding’ of an IP call. (See also chapter on IPLR).

4.1.7 Network Profiles

The TANDBERG 8000 has 3 fixed and 3 programmable Name, Prefix and Protocol settings that may be used when dialling.

The system will automatically make an H.320 call if the dialled number is an ISDN number or an H.323 call if an IP address is dialled. H.323 will also be selected if number prefix is matching the H.323 prefix and the system is registered to a gatekeeper.

4.1.8 Encryption

The TANDBERG system has built-in encryption of audio, video and data for both H.323 (based on ITU standard H.235) and H.320 (based on ITU standard H.233 and H.234) calls. This feature supports DuoVideo, FECC, T.12021, and point-to-point calls as well as MultiSite calls up to total 768 kbps.

The encryption algorithms used in the TANDBERG system are:

- The Data Encryption Standard (DES) with a 56 bit session key

- The Advanced Encryption Standard (AES) with a 128 bit session key

Although there are small differences between H.323 and H.320, a typical set-up of a secure call can be defined as follows:

1. Establishment of a common shared secret and selection of an encryption algorithm.

2. Exchange of the keys according to the common shared secret and the selected encryption

algorithm.

3. Start the encryption.

The establishment of the common shared secret is done through the computation of the DiffieHellman (DH) algorithm. The DH method uses prime numbers of 512 bits length for DES and 1024 bits for AES. The shared secret is then used as a key for the selected encryption algorithm, which encrypts "the session keys". When the session keys are collected by the remote end, encryption of the audio, video and data channels can start.

In a MultiSite call, encrypted and non-encrypted connections cannot be mixed. Consequently, all systems in a MultiSite call need to support encryption in order for the conference to be encrypted.

If one endpoint in a MultiSite call does not support encryption, the MultiSite host will turn off encryption with all other endpoints as well.

T.120 not supported on H.323 point to point calls nor in MultiSite calls

4.2 Aggregation Standards

ISDN Aggregation H.221 Frame Structure from 64(56

ISO 13871 BONDING, Mode 1 from 64(56

4.2.1 BONDING

• ISO 13871, BONDING Mode 1 for bit rates from 56 kbps up to 2 Mbps (1 to 30 channels).

• The TANDBERG system can handle relative delay difference between B-channels of up to

0.5 second (i.e. to compensate for different routing of channels).

Example: Channel 1 is delayed 250 ms, channel 2 is delayed 500 ms and channel 3 is delayed 330 ms. The relative delay difference is then (max. – min.), thus in this case it would be 500 ms – 250 ms = 250 ms (0.250 sec).

If delay difference is more than 0.5 seconds in the call, the TANDBERG system will display ‘Corrupted data received’ and try to resynchronize the call.

Note: Delay difference will vary depending on the different service providers involved in the call.

The following are the standard bandwidths on H.320:

30ch – 24 – 23 – 18 – 12 – 8 – 6 – 5 – 4 – 3 – 2 – 1

) kbps to 128 kbps

) kbps to 2 Mbps

4.2.2 H.221

• For bit rates from 56 kbps up to 128 kbps (1 or 2 channels).

• The maximum relative delay difference between the 2 B-channels is 0.6 second.

• The system will only select H.221 if the far end does not support BONDING or when two

ISDN numbers are dialled.

Only 1 x 64 kbps H.221 support when External Network is used.

4.2.3 Encoding delay

H.320: The latency in a point-to-point call using TANDBERG systems on H.320 (ISDN) varies between 160-250ms depending on the network performance.

H.323: The latency in a point-to-point call using TANDBERG systems on H.323 (IP) varies between 120-160ms. (An additional 100ms have to be added for playout buffering).

NOTE, the total delay of a call will be as follows:

Encoding delay + Max. network delay + Decoding delay

D12008 Rev. 11 30

Page 31

Technical Description of TANDBERG 8000 with software version E3/B8

Network delay (and Delay difference) will vary depending on the different service providers involved in the call.

Decoding delay is typically 1/3 of the encoding delay.

4.3.1 Data Protocols

Please refer to ‘Data port User Guide’ (D11943) for details. There are several different modes for the data ports as described below.

• Data, Dynamic Data Channel mode (data port 1)22

When communicating between two TANDBERG products, this protocol enables the use of a multitude of applications such as:

• File transfer

• Diagnostics

• Application sharing

• remote control

The Codec operates as a modem according to Hayes’ commands.

• Control mode (data port 1)21

In this mode, the Codec can be controlled by an external user interface.

• Modem mode (data port 1)21

When in a call - DDC mode is activated. When not in a call - Control mode activated.

• T.120 mode (data port 1)

The T.120 data protocol enables systems from different manufacturers to do data conferencing- implemented by TANDBERG in the form of the T.120 data communication protocol (MLP).

• Enables the provision of data conferencing capabilities within an MCU call23.

• Covers many different aspects of data conferencing such as application sharing and

white boarding.

• Makes use of MLP and hence requires a suitable application matching your data

communications requirements. TANDBERG recommends Microsoft NetMeeting version 2.0/2.1 or Intel’s IBVC (Intel Proshare) for data conferencing.

• Maximum bandwidth for data in this mode is 32 kbps.

Please, refer to the document ‘Data conferencing & T.120 overview’ (D10632) for details.

• VISCA (data port 2)

For control of cameras using VISCA control protocol.

• AUTO (data port 2)

The auto setting will automatically set the data port 2 dependent on equipment

connected. The following equipment will be automatically identified:

• TANDBERG W.A.V.E. camera. The command set for this camera will be activated.

• Hayes compatible modem. The command set for Hayes will be activated.

• Other control devices. The data port will be set to Control mode.

During the time of use, the RS232 Screen saver connector needs to temporarily be disconnected.

4.3.2 Translation in RS232 cable for TANDBERG 8000 dual monitor

TANDBERG 8000 has an Intelligent VGA <-> S-Video switching device connected to Dataport 1 to utilize the local dual monitor. It will switch to the VGA cable (thus XGA resolution24 on dual monitor) when PC is selected and S-Video cable (xCIF resolution on dual monitor) when e.g. Main Camera is selected.

Furthermore, whenever the TANDBERG 8000 system receives a video stream / presentation in XGA resolution, the presentation will be displayed on the dual monitor. This is applicable to receiving XGA presentations on either the main or the duo video stream.

The command translations done by the chip in the RS232 connector is shown below.

From codec: *S dualmon open = To monitor 1: IN2 To monitor 2: IN4 back to codec: vgamon second

From codec: *P vidin 5 = To monitor 1: IN2 To monitor 2: IN4 back to codec: vgamon second

From codec: *P duovideo ready = To monitor 1: IN2 To monitor 2: IN2 back to codec: vgamon loop

From codec: *P vidin 1,2,3 or 4 = To monitor 1: IN2 To monitor 2: IN4 back to codec: vgamon loop

Note: The command dualmon open is a common command for all DuoVideo sessions, and thus not only for PC. This means that duo video with aux, vcr and doc cam will also be shown in VGA mode.

4.4.3 PC Soft Presenter

The system has implemented a feature that allows PC images to be shown to the codec. A software from ‘Virtual Network Computing’ (VNC) needs to be installed on the PC to make use of this feature (free download from http://www.realvnc.com).

When correctly set up27, the PC image will be used as video input by the system whenever the PC button is pressed on the remote control28.

Note: The VNC Server’s Display Number and Password need to be set on the codec29.

Please, see the User Manual for guidelines of setting up the PC Soft Presenter.

Note: PC Soft Presenter supports the same resolutions as the PC presenter (XGA input). In addition, the VNC server will scale any SXGA input down to XGA.

Implemented according to VESA standards (VGA=Video Graphics Array, SVGA=Super VGA, XGA= eXtended VGA). Note: If image from PC in use is not displayed correctly, changing the PC’s resolution to XGA -> VGA may help. 27

If problems getting VNC to work, one may have to update the driver(s) for the PC graphical card and/or the PC network card 28

The VNC program must be installed as a Server on the PC in use (the codec being the client) and supports Windows, Unix and Macintosh. 29

4.4.6 Optimized Video Compression

The ITU standard H.263 provides:

• Optimized compression and decompression of video at lower bandwidths.

• A sharper picture than provided by H.261.

• Improved contrast and enhanced clarity of the finer details within an image.

• Improved motion handling that removes the characteristic blocking that tends to occur during

normal H.261 movement.

• Near broadcast quality motion handling (iCIF/iSIF) is achieved with the implementation of

certain H.263 annexes, commonly referred to as H.263+ (annex N) and H.263++ (annex W).

• 4xCIF/4xSIF live video

The ITU standard H.264 provides considerably better video quality at lower bandwidths. It has been developed with strong TANDBERG participation in joint workgroups of ITU-T and ISO. H.264 is based on the ISO standard MPEG-4.

The TANDBERG 8000 system supports H.264 video compression in both CIF and SIF resolutions31. An encoding and decoding rate of a high-quality 30fps is achieved. H.264 may be used on the TANDBERG 8000 system for bandwidths of up to 768 kbps.

Under the preconditions named above and depending on the far end’s H.264 support, the TANDBERG system will select H.264 as video compression standard if H.264 has been activated in the menu.

In case H.264 is unavailable at the far end or if the above preconditions are not fulfilled, the TANDBERG system will preferably select H.263.

The TANDBERG system will select H.261 only in case the far end system supports no better video compression algorithm.

4.4.7 Intelligent Video Management (IVM)

It is possible to configure the picture sent from the system depending upon specific requirements and applications adding an additional level of flexibility and adaptability:

Generally, the IVM will always try to transmit the format closest to the video input format.

Motion: When there is a need for higher frame rates, typically when a large number of participants are present or when there is a lot of motion in the picture.

At low bit rate:

• CIF will be used from a PAL video input

• SIF from NTSC

• VGA/SVGA/XGA from PC, Digital Clarity

At high bit rate:

• iCIF will be used from a PAL video input, Natural Video

• iSIF from NTSC, Natural Video

• VGA/SVGA/XGA from PC, Digital Clarity

H.264 only supported from software E2 onwards D12008 Rev. 11 37

Page 38

Technical Description of TANDBERG 8000 with software version E3/B8

Sharpness: Improved quality of detailed images and graphics, lower frame rate, ideal for enhancing quality at lower bandwidths.

• 4xCIF will be used from a PAL video input, Digital Clarity

• 4xSIF from NTSC, Digital Clarity

• VGA/SVGA/XGA from PC, Digital Clarity

Auto: Selected when there is a need for both motion handling and high quality of images and graphics. The system will automatically adjust frame rate and sharpness dependent on movement.

At low bit rate:

• CIF will be used from a PAL video input

• SIF from NTSC

• VGA/SVGA/XGA from PC, Digital Clarity

At high bit rate:

• iCIF will be used from a PAL video input, Natural Video

• iSIF from NTSC, Natural Video

• VGA/SVGA/XGA from PC, Digital Clarity

When Document Camera is selected:

• 4xCIF will be used from a PAL video input, Digital Clarity

• 4xSIF from NTSC, Digital Clarity

4.4.7.1 IVM Resolution

The following table shows relationship between Transmission modes selected by the system when Motion or Sharpness is set in the Call Quality menu. IVM will use this table to optimize the Video quality, according to the capabilities of the remote system(s):

Basic Video Quality

4.4.8 Duo Video

The TANDBERG 8000 is capable of receiving and transmitting two simultaneous H.320 (ISDN or NET interfaces), H.323 or Leased Line E1/T1 video signals33.

System will always try the first transmission mode, and then try the one to the right and so on (as indicated by the arrows) until the proper transmission mode is found. 33

Only possible if the far site can receive Duo Video and both sites have two monitors connected. Natural Video is not supported in Duo Video mode.

D12008 Rev. 11 38

Page 39

Technical Description of TANDBERG 8000 with software version E3/B8

Automatic Duo Video set up

When DuoVideo mode is set to Auto and the remote control buttons; DocCam, Aux, VCR or PC are selected, the system will use this video input as its Duo Video source. The call bandwidth will be split between the main video (including audio etc.) and the Duo Video. Once the Main camera is selected, the system will use all its bandwidth for this video source.

When network is H.323: The system will use approximately 1/2 of its original bandwidth for Duo Video (i.e. the system decides the DuoVideo rate according to the available HSD34 data rates- the DuoVideo rate will be less than the main video rate for higher call rates).

When network is ISDN:

The following table applies for Duo Video Bandwidths*:

Call rate (kbps) Duo Video rate (kbps)

128 64 192 64 256 64 320 128 384 128 512 128 768 256 1152 384 1472 384 1536 384 1920 384

1719 * For restrict use 56k multiples: E.g. 112 -> 56, 168 -> 56 etc

When using the Duo Video feature the main video bandwidth can be calculated by using the formula below:

Main video rate = Call rate – DuoVideo – Audio – Framing (1.6 kbps) – Encryption control (0.8 kbps)

E.g. A 320kbps call using G.722 (56kbps) audio will use: 320kbps – 128 – 56 – 1.6 – 0.8 = 133.6 kbps for main video

When network is Leased Line E1/T1: the maximum Duo Video bandwidth is 768 kbps.

It is possible to change the picture quality (e.g. Digital Clarity) even after a Duo Video signal is set up (Presentations Menu – Duo Video Quality).

Note: In a MultiSite call, the MultiSite ‘host’ can transmit Duo Video to the other sites if these sites have Duo Video support. If some of the connected sites are single monitor systems and have software B5 or later the single monitor systems will see the Duo Video picture (e.g. presentation) and the Duo Video sites will see both presenter and the presentation.

Only possible when both systems have software B3 or later. Description of HSD is found in ITU recommendations: H.221, H.242 and H.243

D12008 Rev. 11 39

Page 40

Technical Description of TANDBERG 8000 with software version E3/B8

The Duo Video functionality supports all H.320 standards, thus it is possible to call two ordinary systems, but there is no audio transmitted in the second duplex H.320 signal.

Duo Video is supported using the H.263 and H.261 video compression standards.

4.4.9 Digital Clarity35

TANDBERG 8000 has the ability to transmit and receive live images using the Native Resolutions VGA, SVGA, XGA or 4xCIF/4xSIF. This feature is called Digital Clarity. When the document camera or the PC is selected, Digital Clarity is automatically selected by the system- the live picture quality will then be crystal clear and the frame rate lower compared to using CIF/SIF36. (See also ch.4.4.7 ‘ Intelligent Video Management’)

The Selfview picture will always be shown in PAL/NTSC video quality.

Whenever the TANDBERG 8000 system receives a video stream / presentation in XGA resolution, the presentation will be displayed on the high-resolution dual monitor. This is applicable to receiving XGA resolution on the main or the duo video stream.

4.4.10 Natural Video (iCIF/iSIF)37

The TANDBERG 8000 is capable of handling interlaced CIF/SIF live video quality. Using the ITU standards’ H.263+ and H.263++ capabilities, iCIF/iSIF enables TANDBERG 8000 to transmit and receive a true interlaced video image near TV quality (i.e. 60 fields per second).

Note: Natural Video may only be used on bandwidths of 384 kbps and above and will automatically be selected at bandwidths of 768 kbps and above if supported by the other system. Natural Video is disabled in H.323 Multi Site calls, H.320 Contionous Presence Multi Site calls, Duo Video calls and if VGA output is used as Main or Dual Monitor.

4.4.11 Native Resolutions

The following live video resolutions are supported on the system:

Native NTSC38:

4xSIF (704 x 480 pixels), Digital Clarity Interlaced SIF (352 x 480 pixels), Natural Video SIF (352 x 240 pixels)

Native PAL:

4xCIF (704 x 576 pixels), Digital Clarity Interlaced CIF (352 x 576 pixels), Natural Video CIF (352 x 288 pixels) QCIF (176 x 144 pixels) SQCIF (128 x 96 pixels)

Native PC Resolutions:

XGA39 (1024 x 768 pixels), Digital Clarity

Receive Digital Clarity is implemented on all TANDBERG systems (Transmit Digital Clarity is part of the NPP software packet) 36

Only possible if the remote site can transmit/receive video in 4xCIF/4xSIF, VGA, SVGA, XGA. 37

To exclude the sending of iCIF/iSIF formats and prevent Interlaced bearer capabilities to be set on system, turn Natural Video off . 38

Source Input Format SIF (4xSIF, iSIF) is an NTSC based video format (Defined in MPEG-1 standard). 39

4.4.12 One-touch Snapshot

The TANDBERG 8000's intelligent One-touch Snapshot button makes it easy to send and receive an image of the highest possible resolution.

• If calling to a dual monitor system the still image will appear on the dual monitor.

• A preview of the still image is possible (set-up in the presentation setting).

• To send a snapshot inside a MultiSite call a snapshot can be sent to all other participants from

the site that holds the floor.

• If the far end supports H.263+ custom formats, snapshot can be sent in VGA, SVGA or

4xSIF.

• If the far end does not support H.263+ custom formats, snapshot will be sent in 4xCIF.

• It is possible to configure the system to always send snapshots from a particular video input,

but requesting a snapshot from another system will always display the current image (i.e. the far end image seen on screen).

Snapshot is implemented according to the ITU standard H.261 Annex D.

By using the Selfview button one may toggle between the last sent/received snapshot and the self-view picture (shown on the dual monitor). It is also possible to view a still image on singlemonitor systems.

4.4.13 Screen Saver

If the system is not in a call, a text string will be shown on the monitor screen after 9 minutes. The user is prompted to select screen saver delay of 30 minutes, 60 minutes or 3 hours. If the user does not respond within 1 minute, the screen saver is activated and both monitors will go black (i.e. the codec sends out a black image). Once the remote control is touched (or any other activation of the system; such as an incoming call), the screen saver will be switched off.

If the system is used for local presentation (i.e. not in a call), it is possible to delay the screensaver prompt via the Quick Keys on the remote control (for 1 or 3 hours).

4.5.1.2 Specification audio line Inputs

Audio in 4: Input 4 enables connection of a microphone amplifier or a microphone mixer if more than 3 microphones are required.

When using an external mixer, it is very important that this is a fixed mixer. Automatic, smart and other types of adaptive mixer will cause the echo canceller to malfunction.

Audio in 5: This input is labelled AUX and is intended for connection to external playback devices or to telephone add-on hybrids.

As there is no acoustic echo canceller on this input, microphone mixers should not be connected.

Audio in 6: This input is specially designed for connection to a VCR but may also be connected to other playback devices. This input will automatically be reduced if a microphone is activated (VCR ducking).

Note: When mode is set to Auto for this input, it will not be enabled unless Video input 4 (i.e.VCR) is selected.

As there is no

acoustic echo canceller on this input, microphones mixers should not be

connected.

When connecting the Audio Science microphone the audio input level should be adjusted to approx. 19.5 dB (in the level settings menu) to obtain optimum performance.

4.5.2 Audio Outputs

In addition to the Codec internal alerting speaker, the TANDBERG 8000 Codec has three audio outputs. The output levels on all three outputs are independently adjustable.

General:

• Using the ‘Audio Output’ menu, the outputs can be independently enabled or disabled.

• Disabled outputs will be muted.

• The audio output levels specify the maximum level of the output.

• When selecting ‘Restore Defaults’, all audio settings will be set to factory-programmed

values.

• The default settings are correct for the TANDBERG Natural Audio modules and for most

consumer electronics (televisions, cassette recorders, VCRs, etc.).

• After installation, audio output level settings should remain unchanged.

Tip to integrators:

The videoconferencing dial tone of the system has a fixed frequency of approximate 420 Hz and a constant level of 24 dB below full scale. The dial tone may therefore be used for calibrating external audio equipment, in order to obtain a proper gain structure. The dial tone is present on the codec’s audio output 1 only, but as the full-scale output levels of all outputs are the same, any setting found on audio output 1 can be directly used on the other outputs. To calibrate to proper level use the audio output level settings in the codec’s menu or adjust the input gain of the external audio device. To ensure correct calibration, it is important that the codec’s volume setting is set to maximum and that all echo cancellers are disabled. Do not calibrate on dial tones in audio calls, as these are not guaranteed to have the same fixed frequency and level.

4.5.2.1 Specification Audio line Outputs

• Audio out 1: Intended for connection to TANDBERG Natural Audio Module, televisions or

audio amplifiers with loudspeakers. The signal on this output is a mix of audio from the remote side, audio from Audio in 5 and audio from Audio in 6. Alert tones and DTMF tones will also be present on this output.

The remote volume control will control the level of the speaker output (Audio out 1).

• Audio out 2: Intended for connection to audio recording equipment or to telephone add-on

hybrid or to an adjacent room. The signal on this output is a mix of audio from the remote side, audio from Mic in 1-3, audio from Audio in 4 and audio from Audio in 6. Local DTMF tones will be present, but alert tones will not be present.

• Audio out 3: Intended for connection to a VCR or other recording equipment. The signal on

this output is a mix of audio from remote side, audio from Mic in 1-3, audio from Audio in 4 and audio from Audio in 5. Neither local DTMF nor alert tones will be present.

The remote volume control has no effect on Audio Output 2 and 3.

4.5.3 Flexible Audio Features

• The TANDBERG 8000 has a flexible integrated audio system, which consists of 6 audio

inputs where any number of audio inputs can be active at the same time.

• When storing presets, all audio settings will be stored together with the selected video

source/camera position.

• The TANDBERG 8000 has lip synchronization for audio.

• Intelligent Audio Mixing: Through adaptive weighting, the system establishes one

microphone as active, automatically determined by the user who is speaking. This feature prevents sounds from inactive microphones or other audio sources from being picked up and eliminates distracting background noise. Intelligent Audio Mixing leverages the capabilities of the four separate acoustic echo cancellers.

• Audio Level Meters. Measures and displays the audio input level for each audio source

independently, providing an on-screen visual aid to ensure optimum audio performance and simplifying installation. ‘Centre point mark’- or slightly below- is the preferred value for best performance.

Additional attenuation is possible on Audio Output 1 by using the remote volume control setting.

D12008 Rev. 11 45

Page 46

Technical Description of TANDBERG 8000 with software version E3/B8

4.5.4 Acoustic Echo Cancellers

Acoustic echo cancelling is provided on Mic in 1-3 and Audio in 4. Each of these inputs has a dedicated acoustic echo canceller. With a separate echo canceller per microphone, the echo cancelling is vastly improved compared to using one common canceller for all microphones.

• Echo cancelling tail length lowest frequency sub band 340 ms.

• Echo cancelling tail length highest frequency sub band 250 ms.

• Max acoustic echo cancellation 70 dB.

If an external echo canceller is used, the internal echo cancelling function should be switched off for the respective audio input.

4.5.4.1 Adjusting the Acoustic Echo Cancellers

The TANDBERG 8000 has the ability to manually adjust the echo cancellers in two ways to obtain the best performance for rooms with special acoustic environments; room size and motion, each controlled by a 0-15 slidebar placed under the echo control menu. Each slidebar defines one common setting for all the acoustic echo cancellers in a system.

When adjusting these settings, please remember that in a video conference between system A and system B, any echo problem on system A will be experienced by the users of system B and vice versa.

Room size: For optimum performance, this setting should be adjusted when the system is installed in a new room.

This setting allows optimization of the echo canceller to the acoustic size of the room where the system is placed. The setting should reflect the acoustic size of the room; two physically equal sized rooms may require different settings, depending on the materials in walls, floor etc. If the materials are hard (windows/metal etc.), the appropriate setting is higher; if the materials are soft (carpets/curtains etc.), the appropriate setting is lower.

Correct setting of the room size parameter will lead to significantly increased echo canceller performance. Adjust the setting if one of two symptoms occurs:

1) There is still some residual echo after a long period of training (audio from the loudspeaker, but no talking in the room where the system reside); Increase the room size setting.

2) The system adapts slowly to acoustic changes in the room (door opens, persons moving etc.); Decrease the room size setting.

Please note that the system will have to readapt each time the room size setting is changed.

Motion: If the system suffers from echo caused by heavy movements in the room, for example people moving close to the loudspeaker and/or microphone; increasing this setting (i.e. number next to slidebar) may reduce the problem.

By increasing this setting, limited voice switching is introduced in addition to the echo cancellation; the higher the setting, the more voice switching is introduced. Therefore, a too high setting may result in clipped words etc. during double talk situations.

D12008 Rev. 11 46

Page 47

Technical Description of TANDBERG 8000 with software version E3/B8

This setting is without memory (i.e. the system does not have to readapt when the movement setting is changed).

4.5.5 Noise Reduction (NR)

Two sorts of noise can be removed when using the TANDBERG 8000, namely low frequency noise and constant noise. The noise reduction algorithms are either both enabled or both disabled.

The constant noise reduction algorithm available on the TANDBERG 8000 is able to reduce noise with a slowly varying level and frequency response, i.e. the reduction is based on an assumption that the noise is constant over time. Therefore, it will reduce noise from fans, airconditioning and PCs, but it will not remove conversation and noise caused by slamming doors, coughing etc.

In case of very high noise levels, the constant noise reduction algorithm may introduce some audio distortion. If distortion is a problem, verify that the microphone input gain is set properly. Too low gain may cause distortion. If gain is set incorrectly, move the microphones closer to the person speaking and adjust the input gain properly.

4.5.6 Audio levelling/ Automatic Gain Control (AGC)

The TANDBERG 8000’s Automatic audio levelling feature will ensure that the transmitted audio will always be at the same level.

• There are four independently selectable audio leveller/AGCs in the system; one common for

Mic 1, 2 and 3 and Audio in 4, one for Audio in 5, one for Audio in 6 and one for audio from the remote side.

• When enabled, the audio levellers try to keep the signal from the corresponding input at a

constant, fixed level, by attenuating very strong signals and amplifying weak to medium signals. Very weak signals, i.e. normal background noise alone, will not be amplified. In very noisy environments, the audio levelling should be turned off for best performance.

• The main purpose of the leveller is to automatically adjust the signals to ensure that each sub

signal in a mix of different sub signals has comparable levels.

• The leveller will also compensate for different speaker levels and different distances from the

person speaking to the microphone.

• To ensure correct behavior of the leveller it is crucial that the input gain settings are adjusted

correctly using the ‘Audio Input level setting’ menu. The leveller will not compensate for severe maladjustments of the input gain settings.

• If using the Audio Bridging feature and calls to mobile phones or analogue phone systems

result in low audio, try setting the ‘Received Audio’ AGC to ON.

D12008 Rev. 11 47

Page 48

Technical Description of TANDBERG 8000 with software version E3/B8

4.5.7 VCR Audio Features

• When a VCR is connected to Audio In 6- and VCR is selected on the remote control- the

audio from the VCR is transmitted to the other side. The audio will also be heard in the local loudspeaker.

• When recording, both local and far end audio will be recorded when VCR is connected to

Audio Out 3.

• Some VCRs (and some other recording equipment) connect the signal on their input directly

to the output when in idle or record mode. This feedback loop will cause echo, both locally and on the remote side. The Codec has a facility that automatically detects and removes this feedback loop. This feature is provided on the Audio in 6 / Audio out 3 pair of connectors only.

• VCR Ducking automatically reduces the audio level during a VCR transmission when one or

several persons speak (from either site). ). I.e. when audio is detected by either Microphone 1-3, Audio Input 4-5 or the incoming audio, VCR Ducking will decrease the audio from Audio Input 6 (VCR). VCR Ducking will automatically adjust the level of the VCR input back to normal if no other audio (than that of the VCR) is detected. This allows for easy voice-over commentary during a VCR broadcast.

4.5.8 Telephony

The system supports point-to-point voice only calls both on the ISDN and IP interfaces, by using the audio compression algorithms described in ch. 4.5.11. See also ch. 4.7 ‘TANDBERG MultiSite’ for adding telephony into a MultiSite call.

4.5.9 Analogue Telephone add-on (US option only)

It is possible to bring in a telephone participant in the videoconference. This is called telephone add-on and is similar to the VCR mode in audio functionality. This feature requires extra analogue telephone add-on equipment.

Please, note the TANDBERG 8000 has the ability to include ISDN telephone calls to mobile phones or analogue phones in a video meeting without any external equipment (ref. Ch. 4.7).

4.5.10 Microphone Off

Pressing the Mic off key on the remote control will mute audio from Mic1, Mic2, Mic3, and Audio in 4. It will not mute audio from Audio in 5 and Audio in 6. When the microphone is turned off any and any of the microphones detects audio, the mic off symbol will flash to warn the user.

D12008 Rev. 11 48

Page 49

Technical Description of TANDBERG 8000 with software version E3/B8

4.5.11 Audio Compression Algorithms

The following audio algorithms are supported on the TANDBERG 8000:

• G.711 48/56/64 kbps, 3.1 kHz bandwidth.

• G.728 16 kbps, 3.1 kHz bandwidth.

• G.722 48/56/64 kbps, 7 kHz bandwidth.

• G.722.1 24 kbps or 32 kbps, 7 kHz bandwidth41.

When system set to Auto, the following are the preferred audio quality priorities on call rates above 192 kbps:

1. G.722 (64 H.323)

2. G.722 (56 H.320)

3. G.722 (48 H.320)

4. G.722.1 (32 H.320, H.323)

5. G.722.1 (24 H.320, H.323)

6. G.728

7. G.711 (64,56,48)*

When system set to Auto, the following are the preferred audio quality priorities on call rates below or equal to 192 kbps:

1. G.722.1 (24 H.320, H.323)

2. G.722.1 (32 H.320, H.323)

3. G.728

4. G.722 (56 H.320)

5. G.722 (64 H.323)

6. G.722 (48 H.320)

7. G.711 (64,56,48)*

(*) H.323 and H.320 will always choose µ-Law before a-Law (for G.711). Telephony will choose algorithm according to the network used.

When using MultiSite and all sites are talking at the same time, the audio from all sites will be processed together. This means all the site’s audio will be heard locally.

24 kbps is used on call rates ≤192 kpbs, 32 kbps >192 kbps.

4.6 System Management

TANDBERG provides a comprehensive set of management tools, and is committed to the use of standards-based tools.

The TANDBERG 8000 can be managed in many ways:

 Locally by remote control  Locally by a computer connected directly to the videoconferencing system (e.g. via

RS232, a standard asynchronous serial port or via the codec’s Ethernet port using a crossover cable)

 Remotely, by a computer connected to the videoconferencing system via

LAN/WAN/Internet

 Remotely, via an external router/modem one can dial into the modem which needs to be

connected to the codec’s Ethernet port

 TANDBERG Management Suite (Optional, purchased separately)

4.6.1 LAN Interface Set-up

The LAN interface supported on the TANDBERG 8000 is 10base-T and 100base-T compatible.

The system supports the following settings of this interface:

• Auto The codec will auto-detect the speed/duplex on the LAN

• 10/Half The codec will connect to the LAN using 10Mbps speed/Half Duplex

• 10/Full 10 Mbps speed/Full Duplex

• 100/Half 100 Mbps speed/Half Duplex

• 100/Full 100 Mbps speed/Full Duplex

In auto negotiate mode, the codec will try to dynamically change to different ethernet speed settings. However, when a forced setting has been made, it will be done during startup, so a reboot is necessary on the Codec.

If problems with codec set to Auto (usually due to switch/hub incompatibilities), please check the following:

a) If switch/hub uses Auto negotiation

Set codec to 100 or 10 half duplex (do not use full duplex)

b) If switch/hub uses Fixed setting

Set codec to the same setting as the switch/hub, ensuring that both speed- and duplexsettings match

‘DHCP’ (Dynamic Host Configuration Protocol) can be selected when a DHCP server is present. When using DHCP, IP-address and IP-subnet mask are not used since the DHCP server assigns these parameters. When using DHCP the address given is displayed in the boot-up text and in ‘Test Network’ in the menu.

If ‘Static’ is selected, the codec’s IP-address and IP-subnet mask must be specified in the TCP/IP settings menu.

To connect to a LAN use a standard Ethernet cable (or order TANDBERG part number

110879). The cable specification is:

D12008 Rev. 11 50

Page 51

Technical Description of TANDBERG 8000 with software version E3/B8

1 ------------ 1 2 ------------ 2

3 ------------ 3 6 ------------ 6

If no LAN is available and the codec is connected directly to a computer, use a crossover cable. The cable specification is: 1 1 2 2

3 3 6 6

If such a connection is needed the codec and PC must use ‘static’ TCP/IP settings because no DHCP server is controlling the small “LAN” which has been created between the computer and the codec. When configuring a back-to-back connection between the PC and the codec, make sure both static IP addresses exist on the same subnet.

4.6.2 Platform Requirements

The management tools are based on standard protocols, obviating the need for special programs running on the management computer.

The management computer may be any computer running a standard operating system. I.e., the management computer may be a Personal Computer running the Windows 95/98/2000/NT operating system, which includes the necessary programs such as:

• An FTP client (please see ‘Upgrading software in TANDBERG Videoconferencing

units’- document D10238- for details)

• A web-browser (please see ‘TANDBERG 8000 User Manual’ for details)

• A Telnet client (please see ‘Data port User Guide’- document D11943- for details)

• A terminal emulator for the RS232 port (please see ‘Data port User Guide’- for

details)

4.6.3 Protocols Supported

TCP/IP - Transport Control Protocol/Internet Protocol, providing connectivity over

LAN/WAN to any networked computer.

HTTP - HyperText Transport Protocol, providing a Web-browser interface to the

management computer. (Max. number of simultaneous connections= unlimited, although only one is processed at a time)

FTP - File Transfer Protocol, providing a standard method for remote software upgrades.

(Max. number of simultaneous connections= 1)

TELNET - providing a standard command-line interface to management functions. (Max.

number of simultaneous connections= 3)

SNMP42 - Simple Network Management Protocol, standard for network management and

surveillance. (RFC1157 SNMPv1, RFC 1213 MIB-II).

DHCP - Dynamic Host Configuration Protocol, enabling the system to automatically be

given IP address and Subnet Mask when connected to a network with a DHCP server.

In addition to the above TCP/IP based protocols allowing management to be performed remotely; local management, control and software upgrade facilities are also available through a standard RS232 interface (see chapter 4.3).

4.6.4 System Management Functionality

4.6.4.1 Remote software upgrades using FTP:

This service is provided by the standard TCP/IP based FTP protocol. Any networked PC may perform software upgrades either locally or over the Internet depending on the LAN connectivity on the customer premises (firewalls etc.). Using any FTP-client software (such as the FTP-client bundled with the Windows operating system), it is possible to upload the new software release to the videoconferencing system. The software file is in binary format in order to decrease upload time. It is possible to keep the directory list and all other special settings after the new software is uploaded.

4.6.4.2 Remote software upgrades during a call43

The TANDBERG 8000 has the ability to upgrade another TANDBERG system when inside a call (IP, ISDN or NET interfaces) by using the built-in file system. The management PC needs to be connected to the calling codec via the Ethernet port to upgrade a remote system. While in a call to the upgrading system, the codec software file should be put into the file system of the local codec; e.g. ftp://LocalCodecIPaddress/remote/s08001e30.pkg. Please see document D10238 ‘How to upgrade a TANDBERG Videoconferencing system’ or User Manual for further info.

It is also possible to do this type of software upgrade via the codec’s web page.

4.6.4.3 Management using a standard Web-browser:

Using a standard Web-browser (Netscape, MS Internet Explorer 3.0 or later), the user may perform basic set-up, diagnostics and troubleshooting. This includes placing calls, disconnecting calls, using the directory as well as remote software upgrading.

4.6.4.4 Management using a standard Telnet-client:

(such as the Telnet program bundled with the Windows operating system)

This gives the user the same functionality as from the remote control and the data port. It provides advanced debug capabilities such as ISDN layer 3 (D-channel) traces on Basic Rate and Primary Rate interfaces, low-level H.320 protocol diagnostics (e.g. H.221 traces), etc. This interface is a command-line type interface, not a graphical interface like the Web-browser interface. The codec supports multiple simultaneous Telnet sessions.

4.6.4.5 Management using a terminal connected to the RS232 port:

(such as using the HyperTerminal program bundled with the Windows operating system).

Provides many of the same services and features as the Telnet-interface does in addition to the possibility to do software upgrades. See chapter 4.3 and TANDBERG Data port User Guide (D11943) for details.

Both systems needs software B3 or later for this type of remote upgrade to function

D12008 Rev. 11 52

Page 53

Technical Description of TANDBERG 8000 with software version E3/B8

4.6.4.6 Remote Management using SNMP:

The TANDBERG system may be managed from a remote Management System such as the TANDBERG Management Suite (TMS) using the Simple Network Management Protocol (SNMP). For further info on SNMP refer to document ‘TANDBERG SNMP’ (D12190).

4.6.5 Security

4.6.5.1 Disable Services

There is no router inside the system that can route between the ISDN side and the IP side of the TANDBERG system. This means it is not possible to get access to the Ethernet port via an ISDN call. However, if wanted the following services may be disabled/enabled (with dataport commands):

• TELNET

• HTTP

• FTP

• H323

• rinfo command

• Remote software upgrade

• SNMP (may also be set to read only)

• MD5 challenge for TMS

4.6.5.2 Security Alert

The system will notify any management application when someone tries remote access over IP with illegal password (via SNMP traps). Information about the intruder’s IP-address and the service used (Web, Telnet and FTP) will be given. When the (optional) TANDBERG Management Suite (TMS) is used, an email notification may also be sent to the administrator of the network.

4.6.6 System Protection

4.6.6.1 System Access (/Account) codes

A System Access Code is an optional verification code before placing a call and is implemented to protect access to the TANDBERG system. Access codes can also be used for accounting purposes in collaboration with the TANDBERG Management Suite (TMS).

Hint: The use of access codes is turned on/off in the Call Settings menu. Therefore, for full protection, use the dataport command protect on <optional password> to ensure that the user cannot turn this protection feature off. (User will then only get read access inside the Terminal Settings menu).

The user enters the access code in the input field and presses OK. The system will verify if the entered code is valid by checking the code with the allowed codes listed in the access.txt file stored on the codec’s ftp-server. (This file must be made and stored on system by the administrator).

If no 'access.txt' file is uploaded to the codec, registration of the code will be done without validation. E.g. you can enter whatever code you want and have access to the system.

If the entered code is invalid, the menu is held on screen and an error message ‘Invalid account code!’ is displayed on the status line and user will not be able to dial from the system.

D12008 Rev. 11 53

Page 54

Technical Description of TANDBERG 8000 with software version E3/B8

Any combination of the characters entered via the remote control may be used as access codes.

Note: It is only in conjunction with the TANDBERG Management Suite that these codes may be used (and referred to) as Account Codes.

4.6.6.2 Menu Password

A menu password is implemented to protect from users entering the menu of the system via the remote control. This is a dataport command and the system may still be accessed via the Ethernet port even when this password is set on the system. Ref. ‘TANDBERG API - Dataport User Guide’ (D11943) for details.

4.6.6.3 Authentication of Remote Management System

In order to increase network security, the TANDBERG system can force remote management systems such as the TANDBERG Management Suite (TMS) to authenticate. Authentication is performed via an MD5 challenge using a configurable TELNET port (port 57 by default).

In the course of authentication, the TANDBERG system provides a "challenge" such as a text string to the management system. The management system must then compute a response using the MD5 hash algorithm from this string and a secret password. The response is used as the management password. It changes every time because the challenge is different every time.

4.6.7 Layer 4 ports used by the system

The following TCP and UDP ports are relevant for the TANDBERG 8000 system.

4.7 Web Snapshots

For monitoring purposes, the TANDBERG system’s web interface shows a snapshot of the incoming video if the system is in a call. Outside of a call, the web snapshot will reflect the local main camera view or another selectable video source on the system. The snapshot image is updated every five seconds.

In a call, the system’s web interface also shows and allows selecting the DuoVideo source.

The snapshot picture information is protected by the following security mechanisms:

• The web snapshots are not stored on the TANDBERG system.

• The web snapshots are protected by the TANDBERG system’s IP password.

• The web snapshots are not visible for encrypted calls.

• The web snapshot functionality is disabled by default. It may be turned on only via the local

codec interfaces (on-screen menu or RS-232 dataport connection).

4.8 TANDBERG MultiSite

The TANDBERG 8000 has a built-in MCU (Multi Conference Unit) providing up to four video sites and one audio site connected in a call with the same high quality audio and video as in a normal point to point call.

TANDBERG MultiSite supports any combination of ISDN and IP sites.

Furthermore, a combination of External Network (V.35\RS449\RS366\X21\Leased Line T1/E1) and IP sites is possible under the following prerequisites:

• An External Network party must be connected first.

• No ISDN parties can be part of the conference.

The MultiSite supports TANDBERG features Digital Clarity, Natural Video45 and Duo Video46.

TANDBERG MultiSite can be used with the H.263 and H.261 video compression algorithms.

Audio Bridge (normal telephone)

The TANDBERG MultiSite may also be used as an ISDN telephone bridge with up to five sites connected; or as a mix of both video- and audio- sites as described in the table below.

Audio Bridge (IP telephone):

It is also possible to add IP telephones into a MultiSite meeting. An IP telephone will ‘count’ as a normal video site. Thus; maximum 4 IP telephones, 3 IP telephones + 1 video, 2 IP telephones + 2 video or 1 IP telephone + 3 video.

The following table shows the maximum bandwidth for each video site; against the number of sites in the conference; when connected to various networks supported on the TANDBERG 8000:

Natural Video only supported on ISDN (H.320) MultiSite calls in Voice Switched mode

Only the ‘host’ can transmit Duo Video in a MultiSite call

MSN must be turned off to be able to add telephones into a MultiSite call OR (if MSN is ON) the telephone call must be connected before the

video sites are added.

When used as an audio bridge only, a maximum of 4 ISDN channels will be used (i.e. 64 kbps per added telephone site).

All video sites must be connected at the same bandwidth but asymmetric video formats are supported; i.e. Digital Clarity may be received while CIF/SIF is transmitted. The system will automatically set up the calls for the best possible audio and video according to the first MultiSite connected.

Automatic bandwidth adjustment

IP: When adding sites to a call, the system will use flow control to utilize the available bandwidth for the call.

ISDN: When adding sites to a call, the system will automatically downspeed to the appropriate number of channels according to the system’s available bandwidth.

The MultiSite is able to accept incoming calls as well as connecting other sites from the TANDBERG 8000; or a mixture of incoming and outgoing calls. To dial into the MultiSite the far sites A, B and C must dial in on TANDBERG 8000’s 1st, 2nd and 3rd ISDN line numbers respectively.

The MultiSite supports Continuous Presence (CP), Voice Switched (VS) or manual mode of operation.

In CP, the screen is divided into 3 or 4 squares and the same image is sent to all participants.

a) If MultiSite terminal holds the floor, it will transmit itself in full screen to the other

terminals, but still see CP on its own screen.

b) If one of the other terminals holds the floor, it will see CP. The MultiSite terminal will

see CP, but also active terminal in full screen (on the other monitor). All other terminals will see full screen of active terminal.

Requires 1-3 ISDN channels available and connected to the system for the telephone calls

D12008 Rev. 11 57

Page 58

Technical Description of TANDBERG 8000 with software version E3/B8

For control of MultiSite, the TANDBERG 8000 supports Request floor, Release floor and Terminal Site naming (System name).

In addition, the host of the MultiSite can use Chair control- i.e. the MultiSite system can choose which site to be viewed by all.

Site naming in MCU: When the terminal is connected to an MCU that supports site naming, a

transparent line will display the site name for approx. 10 seconds every time the MCU switches site.

Note: The ‘Quick Keys’ may be used for easy access to the MCU services menu.

4.8.1 MultiSite Cascading

The TANDBERG 8000 may be cascaded with other MultiSite systems (up to three) to allow for up to 10 video sites and 4 audio telephone sites to participate in the same call (i.e. 14 sites in total).

The cascaded MultiSites may be connected via ISDN or IP.

The ‘host’ MultiSite may be set to Continuous Presence or Voice Switched mode, while the cascaded MultiSites will be set to Voice Switched as shown below.

the sites in Cascaded A is ‘on air’, all sites connected to Cascaded A will see the site ‘on air’ in full picture. The rest of the sites in the conference will see the CP image ‘Picture viewed by all’.

2. Please, also remember the limitations set by the H.323 standard when considering

cascading of MultiSite systems.

If a site or a cascaded MS is connected on IP, the features Site Naming and Request/Release Floor is disabled for these particular systems.

5. Miscellaneous Features

5.1 Multi-language Options

The TANDBERG 8000 supports multiple languages for its on screen menus. The user can select between the following languages49:

• Chinese

• Chinese (simplified)

• English

• French

• German

• Italian

Note: By pressing the following buttons on the remote control the menu is set to English:

Snapshot – Far End – Snapshot – 0

• Japanese

• Norwegian

• Portuguese

• Russian

• Spanish

• Swedish

5.2 Directory

The TANDBERG 8000 can store up to 516 numbers in the directory.

• 100 in the local directory + 16 for MultiSite entries

• 400 in the global directory (stored in codec’s file system)

The global directory can only be edited through the file system (by using ftp). Once the global directory file is stored on the codec (ftp://codecIPaddress/user/globdir.prm), these numbers will appear on the normal directory menu.

Note: The Global Directory numbers may not be edited via the menu nor added into the MultiSite directory.

5.2.1 MultiSite Entries

For easy set-up of regular MultiSite meetings, the system has 16 MultiSite entries. One needs to insert the numbers into the local directory first, then put them into a MultiSite entry. When a MultiSite entry is selected and the connect button is pressed, the system will set up calls to all the sites for that particular MultiSite entry.

Available languages correct at time of printing- additional languages may become available.

Technical Description of TANDBERG 8000 with software version E3/B8

5.3 Boot up logo

It is possible to customize the boot up logo on the TANDBERG 8000 through the codec’s file system. The logo file must be in jpg-format and the file size cannot be larger than 704 x 480 pixels50. The color format of the file should be RGB and the file must be stored under ftp://codecIPaddress/user/startup.jpg. The boot up logo will be shown on screen during boot up, and may also be displayed when system is not in use (selection in menu).

5.4 Startup scripts

When certain settings- other than default settings- are required on the TANDBERG 8000 system, one can run two customized startup scripts. The scripts can contain a series of Dataport commands starting with *P (Ref. Dataport Userguide). 20 seconds after reboot of the codec, these files will be executed in the following order: startup1, globdir, startup2. (See Ch. 5.2 for more info on the globdir file).

The files should be stored under ftp://codecIPaddress/user/startup1.prm (…/globdir.prm …/startup2.prm).

Note! Do not put the command *P boot into these files as this will cause the codec to continuously reboot. (If this is done, ftp into the codec after bootup and delete the file within 10 seconds before its being excecuted).

5.5 Loopback Testing for Remote Diagnostics51

There are two ways of testing network loopback on the TANDBERG 8000.

Request remote loop

A B

Set in local loop

A request is sent to remote side to switch on its loop.

• The local site (A) will see its own video and

hear its own audio

• Remote site (B) will see and hear site (A)

The local system will loop incoming audio and video.

• The local site (A) will see and hear site (B)

• Remote site (B) will see its own video and hear

its own audio

Only applicable for E-software (for B8 and earlier: max bootup logo size is 320x200). By opening the jpg-file in a web-browser one may see the number of pixels of the file (properties) 51

For more diagnostic features on the system, please refer to ‘TANDBERG API – (Dataport User Guide)’ (D11943)

D12008 Rev. 11 61

5.6 Maximum call length

Normally a call will stay up until it is disconnected by the user. The system has the ability to automatically disconnect the call (incoming or outgoing) after a certain time.

Once a value (1-999 minutes; i.e. up to approximately 17 hours) is inserted in the menu this will apply for all calls made. Default value is set to zero (i.e. max. call length off).

When the time has expired, the user will be prompted a ‘need for delay?’ message.

5.7 Closed Captioning/Text Chat

The TANDBERG system has the ability to display text on local and far end screens via the system’s web page. Text chat is supported on both H.320 and H.323 and only in point-to-point calls. The feature is implemented according to the ITU standard T.140.

T.140 defines a universal presentation-level protocol for text conversation which will work with all multimedia protocols and with the existing standard for text telephony; V.18. This is expected to greatly improve the lives of those users reliant on text-based conversation systems, such as the hearing and speech impaired.

Please, see the User Manual for more information about the usage of this feature.

5.8 Other Standards supported

5.8.1 H.320

This ITU standard is a generic name applied to all standards based videoconferencing equipment. By its nature it calls up a number of other standards that are designed to perform a set process to enable the transmission of video, audio and data (i.e. multimedia) across any synchronous network.

5.8.2 H.323

H.323 is an ITU standard that specifies the operation of real-time audio, video and data communications over packet based networks. These networks are collectively termed IP networks and are by nature asynchronous.

5.8.3 H.331 (Broadcast mode)

The TANDBERG system supports the ITU standard H.331 which may be used in special networks where cost of bandwidth is of great importance, such as Satellite networks.

H.331 provides a broadcast mode where one codec sends only and one (or many) codecs receive only- thus, no handshaking is done between the codecs.

An essential technical feature in H.331 is that communication channels cannot be two-way between the information providing terminal and any information receiving terminal because the path from the receiving terminal to the transmitting one is terminated at the exchange. H.331 is separate from, but based on H.320 and caters for particular needs of the broadcasting type multipoint system so that terminals operating for both H.320 and H.331 are easily implemented.

D12008 Rev. 11 62

Page 63

Technical Description of TANDBERG 8000 with software version E3/B8

5.8.4 H.231/H.243 (MCU control)

When connected to an external MCU (Multi Conference Unit) on ISDN or IP networks, the TANDBERG system uses the ITU standard H.231 ‘Multipoint control units for audiovisual systems…’ for MCU controlling features, such as Chair Control and View Site. These features are easily available by using the colored Quick Keys on the remote control. The standard H.243 ‘Procedure for establishing communications between three or more audio- visual terminals..’ is also implemented in the system for MCU connections for both ISDN and IP with the following functionality:

• Floor request and release

• Site naming and view indication

• MultiSite cascading

• Microphone off indication

• TCS-1 password.

5.8.5 H.243 Password

H.243 password is supported by the system. This feature allows you to have a meeting password set in the external H.320 or H.323 MCU and the endpoints must then put this password in to join the meeting. The password must be numerical.

There are two ways of entering this external MCU password:

1) Password entered together with the MCU number

E.g. With MCU number=207987654 and password=1234, the number to dial will be 207987654*1234.

2) Password prompted on screen after the MCU is called

In this case the MCU sends a TCS-1 message to the terminal immediately after the terminal has called the MCU. When the TANDBERG system receives this message, it will prompt the user for the password. If password is correct the MCU will join the system to the conference; if not correct the system will not be connected.

5.8.6 H.281 (FECC)

The ITU standard H.281 is implemented to control the remote site camera and video sources. The TANDBERG system uses H.281 on both H.320 (Synchronous networks) and H.323 (Asynchronous networks).

5.8.7 KG-194/KIV-7 (NATO encryption)

The TANDERG system supports the NATO encryption standard KG-194. This requires external cryptographic equipment to be connected between the codec’s NET port and the network (the same equipment is required at the remote end).
