Contents Introduction
Glossary, continued...
ETHERNET SPEED: The speed (Mbps) on the connection from the
system to the LAN.
F
FALLBACK TO TELEPHONY: Enables fallback from video calls to
telephony/speech calls.
FAR END: In a video conference, Far End means the remote side of
the conference. Far End Camera is your conference partner's camera.
Opposite to Near End
FECC: Far End Camera Control. When activated it is possible to control
the far end's camera, select video sources, activate presets and request
still images.
FLOOR: In a multipoint call, use Request Floor to broadcast your
picture to all other participants. This is handy when you are having
presentations, for teachers etc.
G
G.711: Audio algorithm for normal quality audio (telephone quality, 3.1
kHz) The system will always have G.711 enabled.
G.722: Audio algorithm for high quality audio (7 kHz).
G.722.1: Audio algorithm for compressed high quality audio (7 kHz)
G.728: Audio algorithm for compressed normal quality audio (telephone
quality, 3.1 kHz)
GATEWAY: The gateway enables sites on IP and sites on ISDN to
participate in meetings with each other.
GLOBAL PHONE BOOK: A phone book provided by TMS.
H
H.261: Video algorithm for legacy video compression and
decompression. The system will always transmit H.261
H.263: Video algorithm for normal video compression and
decompression
H.264: Video algorithm for bandwidth-efficient video compression and
decompression
HARDWARE SERIAL NUMBER: A unique number (listed in the System
Information menu) to identify your system towards your TANDBERG
representatives.
HUMFILTER: A high pass filter which reduces very low frequency noise.
I
ICIF: Interlaced CIF, 352x288 pixels, 50 fields per second
D14033.06—AUGUST 2010
Getting started The menu structure The settings library
INCOMING CALL: Someone calls in to your system
INCOMING MCU
a visual/audio indication of an incoming call and ask to accept or reject
the call.
IP ADDRESS: Defines the network address of the system. This address
is only used in static mode.
IP ASSIGNMENT: IP-address, IP-subnet mask and Gateway are
assigned by the DHCP server.
IP ASSIGNMENT
must be specified in the IP-address field.
IP PRECEDENCE: Used to define which priority the system should have
in the network. Higher numbers indicate higher priority.
IP SUBNET MASK: Defines the type of network. This address is only
used in static mode.
IP TOS: IP Type Of Service. Helps a router select a router path when
multiple paths are available.
ISIF: Interlaced SIF, 352x240 pixels, 60 fields per second
L
LAYOUT: Use the Layout key to change picture layout on the screen.
M
MAIN CAMERA: Your camera. Video input 1
MAX CALL LENGTH: This feature will automatically end both incoming
and outgoing calls when the call time exceeds the length specified.
MAX CHANNELS: Indicates the maximum number of channels the
system is allowed to use on the E1/T1 interface.
MCU: Multipoint Conference Unit.
MCU STATUS LINE: Shows indicators for MultiSite, MCU and DuoVideo
MICOFF: Microphone is switched off.
MIX MODE: How to adjust the weighting of each microphone to obtain
the best possible audio and minimize the background noise.
MODEM MODE: (Dataport) Supports external control of the system
via a PC as in Control Mode. Once a call is established, Dataport 1 will
automatically switch to Data mode. When the call disconnects, Dataport
1 switches back to Control Mode.
MSN: Multiple Subscriber Number. Possible to attach different ISDN
terminals, with different numbers, to the same physical ISDN telephone
line. The service can be ordered from the telephone company.
MULTIPOINT CALL: A call with more than two participants including
yourself
MULTISITE: The TANDBERG systems internal MCU. Built-in system
which makes it possible to establish meetings with up to 6 video
Using the system Physical interfaces
CALLS: If occupied in a call, the system will provide
STATIC: The system's IP-address and IP-subnet mask
Administrator Guide
Peripheral equipment Appendices Appendices
calls and 5 telephone calls. The MultiSite option is not available on all
systems.
MULTISITE CASCADING: By connecting up to 4 or 6 (depending on the
system capacity) MultiSite systems together to achieve a higher number
of participants in a multipoint call.
N
NAT: Network Address Translation. NAT support in the video
communication system enables proper exchange of audio/video data
when connected to an external video system when the IP traffic goes
through a NAT router. Used in small LANs, often home offices, when a
PC and a video communication system is connected to a router with
NAT support.
NAT ADDRESS: The external/global IP-address to the router with NAT
support. Packets sent to the router will then be routed to the system's
IP address.
NATURAL AUDIO MODULETM: Designed to improve audio quality
during a video conference. It is mounted in the cabinet above the Codec
and consists of an audio system optimized for speech.
NATURAL PRESENTER PACKAGE: Consists of DuoVideo, Digital Clarity
and PC Presenter.
NEAR END: In a video conference, Near End means your own side of
the conference. Near Camera is your own camera. Opposite to Far End
NETWORK CLOCKING: Specifies the number of physical external clock
signals.
NETWORK INTERFACE: Indicates if the network is of type E1 or T1.
NETWORK PROFILES: It is possible to define up to 6 network profiles,
each consisting of name and call prefix, and three of them also include
network selection.
NON STANDARD FACILITY: The network provider may require service
selection in your ISDN configuration. Valid NSF codes are from 1 to 31.
0 will disable NSF service codes.
NR: Noise Reduction. Reduces constant background noise (e.g. noise
from air-conditioning systems, cooling fans, etc.).
NSF: Non Standard Facility.
NTSC: National Television System Committee. Video standard
corresponding to 4SIF. Primary used in USA, Japan and other countries.
O
OPTION KEY: Required by the system to activate optional features such
as MultiSite and Presenter.
P
PAL: Phase Alternation by Line. Video standard corresponding to 4CIF.
