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
INCOMING CALL
: Someone calls in to your system
INCOMING MCU CALLS
: If occupied in a call, the system will provide
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 STATIC
: The system’s IP-address and IP-subnet mask
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
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.
