Making and ending calls
Making a call
connect
To make a call, enter the number or the IP-address of the unit you wish to call using the Dialing keys
and press CONNECT.
ISDN call
The system will, by default, try to connect using Quality: Auto (see table overleaf). If the requested quality
(bandwidth) cannot be established, the system will establish a connection on as high quality as possible.
The SoftMux ensures high reliability and includes the unique Downspeeding feature. If channels are dropped
during a meeting, Downspeeding automatically maintains the connection without interrupting the call in progress.
The SoftMux also enables you to dial to other videoconferencing equipment, phones and mobile phones in the
same way and provides you with on-screen, real-time feedback on the progress of a call.
LAN call
To make a call via a LAN, enter an IP-address by using a * as the ‘dot’ in the IP-address, e.g. 123*3*0*12 will be
interpreted as 123.3.0.12. If a gatekeeper is present, you may place IP-calls using “telephone-style” numbers (an
E.164 alias), according to the numbering plan implemented in the gatekeeper. The dialed number will then be
translated into an IP-address by the gatekeeper.

Access Code
If the system requires an Access Code, enter the code and press OK to proceed making a call:
Using sub-address / extension address / MCU password
To specify an ISDN sub-address or its LAN equivalent extension address (TCS-4), add a star (*) after the number
and then enter the sub-address/extension address.
Example:
12345678*10 ( <number>*<Sub-address/extension address/MCU password>)
When calling to external MCU’s requiring a password (TSC-1), this password can be added after the star (*). If no
password is specified, a menu will prompt you to enter the password (after connected to the MCU).
SUB-ADDRESS IS USED TO ADDRESS DIFFERENT SYSTEMS ON THE SAME ISDN LINE.
TCS-4 IS USED TO ADDRESS DIFFERENT SYSTEMS ON A LAN, WHEN DIALING IN VIA A GATEWAY.

MultiSite (MCU)*
The system has a built-in multipoint conference unit (MCU), MultiSite, which has the capability to establish
meetings with up to 4 video sites (5 if at least one site is a telephone call, ISDN/analogue/mobile).
The video calls in a conference must be connected using the same bandwidth.
A conference can consist of any combination of ISDN/
LAN sites.
It is possible to have telephone meetings with up to 5
participants.
The MultiSite supports both Voice Switched and
Continuous Presence mode (see ‘MCU Services’ in
‘Advanced use’ for description of these modes).
Establishing a conference is done by first making a call
to one site. When a call is established with the first site,
the other sites are connected one by one.
It is possible to either dial out to the sites or the sites
can dial in to the MultiSite.
Both ISDN, IP and mixed ISDN/IP conferences can be
encrypted if all systems supports encryption.
SEE ‘UTILITIES’, ‘CONTINUOUS PRESENCE’ TO CHANGE MODE.
TIP
For encrypted calls, there is also a maximum bandwidth of 768 Kbps for the whole conference. This means that a
3 site conference will have a maximum bandwidth of 384Kbps per connection, while a 4 site conference will have a
maximum bandwidth of 256 Kbps per connection.

Audio input 4 is intended for connection to a VCR. It can also be connected to other external playback devices.
As there is no acoustic echo canceller on this input it should not be connected to any microphones. The audio
source connected to this input will be heard from the local speaker.
Mix Mode
‘Auto’ automatically adjusts the weighting of each microphone to obtain the best possible audio and minimizes
the background noise. ‘Auto’ will also attenuate the VCR audio level when someone talks into a microphone.
‘Fixed’ will maintain a constant weighting for all microphones.
Level Settings
Adjust the audio input levels according to which external audio equipment is connected. The on-screen audio level
indicator will make it easier to set the correct input level settings. The input level should be adjusted so that the
average level reaches the preferred level marker.
The audio inputs are adjustable in steps of 1.5 dB from 0 dB to 22.5 dB.
The default levels for Mic 1 and 2 are set for use with anAudio TechnicaAT871 microphone in an average
videoconferencing room. The gain can be adjusted correctly for a wide range of microphones.
A few examples of microphone levels are:

Audio out 1 is intended for connection to televisions or audio amplifiers.
Audio out 2 is intended for connection to audio recording equipment or to a telephone add-on hybrid. The signal is
a mix of audio from both the far end and local end (not from Audio in 3).
Audio out 3 is intended for connection to a VCR or other recording equipment. The signal is a mix of audio from
far end and local end (not from Audio in 4).
NOTE NEVER CONNECT AUDIO OUT 2 OR AUDIO OUT 3 TO A LOUDSPEAKER PLACED IN THE SAME ROOM AS THE MICROPHONES CONNECTED TO THE
SYSTEM. DOING THIS WILL CAUSE “HOWLING” AND POSSIBLE DAMAGE TO THE SPEAKER SYSTEM.
If an output is ‘Off’, no audio will be sent to that output.

Adjust the audio output levels according to the parameters of the external audio equipment connected. These
levels should only be adjusted when installing new audio equipment. The default settings are correct for the

Echo Control
Each of the 2 microphone inputs have a separate echo canceller. One echo canceller per input provides more
sophisticated control than having one common canceller for all microphones.
Echo control is normally set to ‘On’ to prevent the far end from hearing their own audio. Once selected, echo
cancellation is active at all times. The echo canceller continously adjusts itself to the audio characteristics of the
room and compensates for any changes it detects in the audio environment. If the changes in the audio
conditions are very significant the echo canceller may take a second or two to re-adjust.
You can choose to switch off the echo canceller for the available audio sources.
NOTE
ECHO CONTROL SHOULD BE SWITCHED ‘OFF’ IF EXTERNAL ECHO CANCELLATION OR PLAYBACK EQUIPMENT IS USED. IT IS YOUR ECHO CANCELLER
THAT IMPROVES THE AUDIO QUALITY EXPERIENCED BY THE OTHER SITE. WHEN YOU HEAR AN ECHO OF YOUR OWN AUDIO IT IS MOST LIKELY THE FAR
END’S ECHO CANCELLER THAT IS MALFUNCTIONING.
Noise Reduction
In addition to echo cancellation, the system has built-in noise reduction (NR).
NR reduces constant background noise (e.g. noise from air-conditioning systems, cooling fans etc.). In addition, a
highpass filter (Humfilter) reduces very low frequency noise.
Choose On+NR to activate both Echo Control and Noise Reduction.

Room Size
This setting allows optimization of the echo canceller to the acoustic size of the room. Hard walls, many windows

setting (NOTE: on the far end) if one of the following symptoms occur:
•
•
There is still some echo of your own audio. Increase the setting.
The system adapts slowly to acoustic changes in the room. Decrease the setting.
After a change, the system will need a few seconds to re-adjust.
Motion
If you experience echo caused by movements in the room, increase the value.

Automatic Gain Control (AGC) Settings
Select ‘On’ to allow automatic adjustments (Automatic Gain Control) of audio levels. When ‘On’, the AGC
maintains the audio signal level at a fixed value by attenuating strong signals and amplifying weak signals. Very
weak signals, i.e. noise alone, will not be amplified.
Example: In most conferences, the participants will speak at different levels, and be at different distances from the
microphones. As a result, some of the participants would be harder to hear than others. The AGC corrects this
problem by automatically increasing the microphone levels when “quiet” or “distant” people speak, and by
decreasing the microphone levels when “louder” people speak.
TO ENSURE CORRECT BEHAVIOUR OF THE AGC, IT IS CRUCIAL THAT THE LEVELS ON THE INPUT CONNECTORS ARE ADJUSTED CORRECTLY USING THE
AUDIO INPUT LEVEL SETTINGS. THE AGC WILL NOT COMPENSATE FOR SEVERE MISADJUSTMENT OF INPUT LEVELS.
NOTE
When applying a weak signal in the presence of strong background noise, theAGC might amplify the background
noise as well as the signal. Therefore, in noisy environments, it is advisable to turn the AGC off.
Tips for improving the echo canceller performance:
• Place all microphones as far as possible from the loudspeaker. Minimum loudspeaker-microphone distance
should be 1 meter.
• Place all microphones as close as possible to the persons speaking. By using several microphones, the ratio
distance loudspeaker-to-mic/mic-to-speaker can be increased. Increasing this ratio improves the echo canceller
performance. Avoid distances above two meters from any participant to his/her closest microphone. If
necessary, use several microphones. Also avoid placing microphones less than one meter from any person.
• Place all microphones as far as possible from noise sources.
• Reduce the volume setting. Ensure that the loudspeaker does not distort the audio.

TANDBERG Videoconferencing System
• The echo canceller tries to estimate the echo path from the speaker system to the microphones. Moving objects
change this path, therefore try to avoid moving objects. Be especially aware of large objects and objects placed
close to either the microphone or the speaker system as these objects will cause severe changes to the echo
path.
• Avoid putting paper sheets etc. on the microphone.
• Avoid moving the microphone or loudspeaker.
• In the event of poor echo cancelling, allow the canceller to adapt. After each change, the echo canceller
requires a few seconds to adapt. Do not change the settings without allowing the echo canceller to adapt to
the new audio environment.
• In the presence of low frequency noise, enable the noise reduction (NR).
Alert Tones & Volume
To help distinguish between incoming video calls and ordinary telephone calls, different ringing tones may be
selected. You may also select different volume levels for the ringing tone.
Alert Speaker
The system also has an internal, call alerting speaker.
On: The internal speaker will warn you of an incoming call even though the monitor may not be switched on.
Key Tones
The Key Tones may be switched on and off.
Restore Audio Defaults
There are many audio settings and the codec could easily be made unusable by configuring these by mistake. It
is therefore possible to return all audio settings to their factory default settings by using Restore Audio Defaults.

External network settings
NOTE
IMPORTANT: THE PHYSICAL INTERFACE ON
EXTERNAL NETWORKS IS ONE NON-STANDARD 26 PIN
CONNECTOR. SPECIAL CABLES ARE REQUIRED.
Before using the system together with external network equipment, you must specify the network parameters on
this page.
NOTE THE SYSTEM HAS SUPPORT FOR UP TO 384KBPS USING THE EXTERNAL NETWORK (RS449/V.35/X.21) INTERFACE.
Call Control
‘RS366 Dialing’ is the only dialing protocol and would normally be used together with network clocking ‘RS449/
V35 Compatible’ when the external equipment uses RS366 ports.
‘Leased Line’ is a non-dialing protocol and should be used when two codecs are connected in a point to point
connection. Use ‘Leased Line’ when the handshaking signals DTR and CD are available. DTR and CD
correspond to the X21 network’s C and I signals.
‘Data Triggered’ mode uses TxData (transmit data), RxData (receive data) and clock signals only. Use ‘Data
Triggered’ when no handshake signals are available.
‘Manual’ should be used when no handshake signals are available, and the external equipment requires a
constantly connected line.
TO MAKE AN IP CALL WHEN ‘LEASED LINE’ IS SELECTED, ENTER A NUMBER BEFORE PRESSING CONNECT TO ACTIVATE THE DIAL MENU.

WHEN STREAMING, A MULTISITE OR A DUO VIDEO
NOTE
CALL CAN NOT BE MADE.
NOTE AN ON-SCREEN INDICATOR IS SHOWN WHEN STREAMING IS
ACTIVE.
Address
Address is defined as the IP-address of a streaming client, streaming server or a multicast address. Giving an
address in the range 224.0.0.1-239.255.255.255 will broadcast the stream to any host that has joined the
specified multicast group. Specifying normal broadcast address 255.255.255.255 will broadcast to any
members on the LAN.
Address Port
If several codecs are streaming to the same IP-address, different ports have to be used in order for the client to
know which stream to receive. If the first codec streams on port 2240 and the second codec on port 2250, the
client has to specify which port to listen to. Video is transmitted on the specified port, audio is transmitted on
the port number 4 above the specified video port, in this case 2244 and 2254.
TTL/Router Hops
This is used for streaming data to limit how many routers the data should pass before it is rejected. If TTL is
set to 2, data will not traverse more than 2 router hops.

Local Only the local video will be streamed.
Remote Only the far end video will be streamed.
Local and far end audio is always streamed.
Allow Remote Start
On
Off
Streaming can be started from external user interfaces like the Web-browser or Telnet session.
Streaming can only be started from the Video Conferencing System using the remote control, or by
using the Dataport. This will prevent activation of streaming using Web browser or Telnet sessions.
Announcements
On
Off
The codec will announce to the network that it is streaming. This enables a streaming client (e.g. a PC)
to connect to the codec’s streaming session. Used by Cisco IP/TV.
No announcement packets will be transmitted.
Video Rate
Defines the Video streaming rate from the system. Range is 16kbps - 320kbps. In addition, audio (G.711)
streaming rate is 64kbps, providing a maximum streaming rate of 384kbps.
Password
Set password so that only participants entering correct password will be able to view the streaming session.
Entering a password will prevent unauthorized people from accessing the streaming session.
Start/Stop Streaming
By pressing the Quick Key labeled ‘ Start Streaming ‘, the Streaming session will start. To stop the stream, press
the same quick-key, which will be labeled ‘ Stop Streaming ‘ while the streaming-session is active. Pressing
Disconnect will also stop the streaming session.
How to view streaming
After streaming is started, an easy way to view the streamed audio/video is to start your Web-browser and enter
the IP-address of the streaming system. After the Web page of the codec is shown, click on ‘Streaming’.
Alternatively, enter http://<codec ip-address>/stream.sdp.

E.164 alias
This is the E.164 address of the codec. The E.164 address is equivalent to a telephone number, sometimes
combined with access codes. Valid characters are 0-9,* and #.
When using a gatekeeper the codec will send a message to the gatekeeper containing both the E.164 address
and the system name of the codec. The codec will not register with the gatekeeper if the E.164 alias is not set.
Use Gatekeeper
Auto
The codec will automatically try to register on any available gatekeeper. If a gatekeeper responds to the
request sent from the codec within 30 seconds this specific gatekeeper will be used. If no gatekeeper
responds, the codec will not use a gatekeeper for making H.323 calls and hence an IP-address must be
specified manually.
Manual The codec will use a specific gatekeeper identified by ‘Gatekeeper IP-address’.
Off The codec will not use a gatekeeper and an IP-address must be used in order to make an H.323 call.

can be done. When ‘On’, ‘Use Gatekeeper’ and ‘Gatekeeper IP’ is disabled.
Off
The codec will not use Cisco CallManager.
CallManager IP
The CallManager IP-address specified here will be used if ‘Use CallManager: On’.
H.323 Prefix
When dialing a number prefixed with digits specified by ‘H.323 Prefix’, and with ‘Net: Auto’, an H.323 call will be
placed. Example: H.323 Prefix is ‘555’. Dialling ‘55582’ with ‘Net:Auto’ will select LAN.

NAT
NAT, Network Address Translation, is used in small LAN’s, often home offices, when a PC and a
videoconferencing system is connected to a router with NAT support. NAT support in the videoconferencing
system enables proper exchange of audio/video data when connected to an external videoconferencing system
(when the IP traffic goes through an NAT router).
When NAT is On, the NAT Server Address will be shown in the startup-menu: ‘My IP Address: 10.0.2.1 (NAT)’
NATAddress
This must be the external/global IP-address to the router with NAT support. Packets sent to the router will then be
routed to the codec.
In the router, the following ports must be routed to the codec’s IP-address:
Port 1720
Port 5555-5560
Port 2326-2365
Please contact your TANDBERG representative for further information.
H.323 Ports
Static
When selecting static H323 ports for TCP connections the ports 5555 or 5556 will be used for
Q931 and H245 respectively.
Dynamic
The operating system will allocate which ports to use when opening a TCP connection.. The
reason for doing this is to avoid using the same ports for subsequent calls as some firewalls
consider this as a sign of attack.

AudioScience microphone
TANDBERG's award-winningAudioScience microphone is a ceiling-mounted, wide coverage, boundary
microphone, that can eliminate the need for table microphones. It is designed to pick up the audio from all
conference participants seated within in its pick-up area, defined by a quarter-sphere of approximately 14 foot
(4.25m) radius extended in front of, and to the sides of the microphone.
Please contact your TANDBERG representative for further information.
Tracker
The Tracker is a small infrared remote control device made to used to steer the system
camera to any desired location within the room. Typically, several Trackers would be used
with each system.
Each Tracker has two buttons:
• One button to point the camera at a specific person/location.
• One button to point the camera at all participants.
Beneath the battery in the tracker, there is a switch which can be set to 16 different positions
between 0 and F. For preset 10 to 15, the numbers 9 to F should be selected. Please refer

TANDBERG Videoconferencing System
Appendix 3: Environmental considerations
This section explains how to carry out basic adjustments and simple tests to ensure that you send and receive the best
possible image and audio quality when using your system.
Iris control and lighting
By default the system camera will use an automatic iris to compensate for changes in lighting. In addition to this feature
you may further assist the system to maintain the best possible image quality by paying special attention to
environmental lighting and background colors as described below. Remember the system will send live images of
yourself and your immediate surroundings.
•Avoid direct sunlight on the subject matter i.e. yourself, the background or onto the camera lens as this will create harsh
contrasts.
•If light levels are too low you may need to consider using artificial lighting. As described above, direct illumination of the
subject matter and camera lens should be avoided.
•When using artificial lighting, ‘daylight’ type lamps will produce the most effective results. Avoid colored lighting.
•Indirect light from shaded sources or reflected light from pale walls, often produces excellent results.
•Avoid harsh side lighting or strong light from above. Strong sunlight from a window or skylight may put part or all of the
subject matter in shadow or cause silhouetting.
•If you still have problems with the iris and lighting, manual adjustment of the camera parameters might help - see ’Video
Settings’ menu.
•Dim scenes can also be improved by manually adjusting the camera brightness setting.
Background
The appearance of the picture background is very important but easily overlooked. It is important to remember that the
camera also shows what is behind you when in a videoconference. To ensure a suitable background we recommend you
consider the following:
•Use a neutrally colored background with a medium contrast and a soft texture, e.g. a plain curtain with no heavy patterns
or strong colors that may adversely tint the whole scene.
•Avoid moving backgrounds such as curtains blowing in a draught, moving objects, or people walking behind as this may
both reduce image quality and distract the attention of the calling party.
•Do not place the camera facing a doorway.
Loudspeaker volume
The audio system will use the loudspeakers built into the TV monitor. The volume of the audio system is controlled by the
Volume Control keys on the system hand-held remote control.
The default volume level can be set by adjusting the volume on the TV monitor using the TV monitor’s own remote control.

Guidelines for setting up videoconferencing rooms
The following are a set of guidelines to consider when either building a videoconferencing room, or using an
existing room for videoconferencing.
Lighting:
Audio:
- Low Contrast desired for light intensity. No dark spots.
- Intensity @ table 800 - 1400 Lux as measured with an Incident light meter.
- Block sunlight from entering room.
- Noise Floor preferred less than 44dBC.
- Reverb Time .3 to .5 sec.
- Ventilation:
Seating Area (Table):
- Keep in mind Noise Floor.
- Velocity = Noise. Therefore keep velocity of air low.
Room:
- Should be located away from noise
- Should not have windows
- Doors should be located off camera
- Should allow all participants to see Monitors.
- Should allow camera to “see” all participants.
- Non-shiny non-patterned preferably light grey surface (if table used).
Walls:
- Color: Generally high contrast color desired. Light blue is commonly used.
- Acoustically reflective surfaces (such as glass or concrete) should be
covered with curtains or sound treatment.
How to prepare a typical room for videoconferencing
The diagram below shows a typical room designed to obtain the best results when using the system.
The microphone should be placed at the front of the table to ensure
that all speech will be detected. The best position for the microphone
1–3: Prestored camera views
is at least 2 meters (6.5 feet) in front of the system on a plain, flat
table with at least 0.3 meters (12 inches) of table in front of the
Document camera
microphone.
system
Microphone
The document camera should be close to the chair person or a
designated controller of the document camera for ease of use.
(Remember to arrange all the peripherals so that one participant can

The illustration shows three possible camera positions; one for all
the participants, one for the whiteboard and one for the main speaker.
The remaining presets are then available for other peripheral
equipment, for example: a VCR.
Position the system in such a way as to avoid the possibility of
somebody inadvertently walking into the camera’s field of view when
entering the room. Other than the conference participants, there
should be no moving items in the sent image.

Appendix 6: Security
The TANDBERG Videoconferencing Unit has several features both to protect from unauthorized use and system
access:
Access Code:
When ‘Access Code’ is enabled, the user will be asked to enter an access code before he/she is able to make a call.
The system will verify if the entered access code is valid by checking the code with the allowed codes listed in the
‘access.txt’ file on the ftp-server in the codec.
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.
The ‘access.txt’ file is a plain text file with one line per access code as shown below:
1234
1250
A1
B2
ABC
To upload this file to the codec, follow these steps:
· Open a DOS-window and go to the folder where the ‘access.txt’ file is located.
· Type ftp <IP-address of your local codec>.
· ‘User:’, press Enter or enter IP-password.
· Type “bin” and press Enter
· Go to the user folder, type “cd user”.
· Upload the ‘access.txt’ file, type ‘put access.txt’.
· Exit from ftp, type ‘bye’.
Menu Password:
Access to the menu system on the TANDBERG Videoconferencing unit can be controlled using password protection.
This is done by using the following dataport command:
menupassword set <pin-code>. The pin-code should be maximum 5 - five digits. To erase the menu password, enter
an empty pin-code.

TANDBERG Videoconferencing System
Appendices
Streaming password
By setting a streaming password in the streaming menu on the TANDBERG codec, a password have to be entered on
the streaming client to be able to see the videostream from the TANDBERG Videoconferencing Unit.
IP Password
By setting a IP Password on the TANDBERG codec, all access to the system using IP (Telnet, FTP, WEB) requires a
password. This password can be enabled from telnet or dataport using the command: ippassword <ip-password>. The
default IP password is ‘TANDBERG’.
To remove this password, use the command: ippassword ””. From telnet, this is only possible by first entering the
correct password.
Services
The different IP services on the TANDBERG codec - FTP, Telnet, HTTP, SNMP and H.323 can be disabled to prevent
access to the system. By using the commands below, the services can be independently enabled/disabled:
services <telnet/ftp/http/h323/remote-software> <enable/disable>
services <snmp> <read-only/enable/disable>
services <telnetchallenge> <enable/disable> [port]
SNMP Security alert
This function will notify any Management Application (such as TMS - TANDBERG Management Suite) if anyone tries to
perform Remote Management on the TANDBERG Codec using a illegal password. The Security alert that is sent to the
Management Application will contain information about the IP address and the service (WEB, Telnet, FTP) being used
for the attempt.
If TMS is used, email notifications or alarms about the attempt can be sent to specified persons.

Appendices
TANDBERG Videoconferencing System
Encryption
All TANDBERG systems support both AES* and DES encryption. By default this feature is enabled such that
when connecting with any other video system or MCU, a TANDBERG system will attempt to establish a secure
conference using AES* or DES encryption. The TANDBERG system will attempt this for both IP and ISDN
connections. Where a remote system or MCU supports encryption, the highest common encryption algorithm will
be selected on a port by port basis.
The type and status of the encryption negotiated is indicated by padlock symbols and on-screen messages.
Encryption on the TANDBERG systems is fully automatic, and provides clear security status indicators;
An open padlock indicates that encryption is being initialized, but the conference is not yet encrypted.
Single padlock indicates DES encryption.
Double padlock indicates AES encryption.
In addition to on-screen indicators the ‘Call Status’ menu provides two information fields regarding call encryption.
The first field is the ‘Encryption Code’ which will identify either ‘AES’ or ’DES’. The second field is the ‘Encryption
Check Code’ and is comprised of an alphanumeric string. This string will be the same for systems on either side
of an encrypted conference. If the Check Codes do not match this would indicate that the call has been exposed
to a ‘Man In The Middle’ attack.
When a TANDBERG codec with MultiSite functionality hosts a conference, the highest possible encryption
algorithm will be negotiated on a site by site basis. MultiSite conferences can therefore support a mix of AES
and DES encrypted endpoints in the same conference.
A conference will only be as secure as its ‘weakest link’. Even though conference participants may have
negotiated and be running AES encryption, if just one participant has negotiated DES encryption, the AES
system will display the single padlock symbol to advise all users of the lowest encryption mechanism currently in
effect.
All TANDBERG endpoint supporting DES encryption can upgrade toAES encryption by applying TANDBERG’s
AES Encryption option. Please contact your TANDBERG representative for more information.
The standards supporting the encryption mechanisms employed by TANDBERG are:AES*, DES, H.233, H234
and H.235 with extended Diffie Hellman key distribution via H.320, H.323 and Leased Line connections.
THE TANDBERGAES IMPLEMENTATION IS VALIDATED AS CONFORMING TO THE ADVANCED ENCRYPTION STANDARD (AES)ALGORITHM, AS
SPECIFIED IN FEDERAL INFORMATION PROCESSING STANDARD PUBLICATION 197, ADVANCED ENCRYPTION STANDARD, BY THE THE NATIONAL
INSTITUTE OF STANDARDS AND TECHNOLOGY (NIST)
