3.1.3 Setting H.323 Parameters
The H.323 parameters must be set when the GK is used in the conference system.
Prerequisites
The GK is used in the conference system.
Context
When the GK is used in the conference system, the endpoint can be configured with a site
number. Other endpoints that also have registered with the GK can then use the site number as
well as the IP address to call your endpoint.
The GK is the network isolator of the videoconferencing system and is used to manage the network
bandwidth, endpoint authentication, and address translation. It enables calls to be made to fixed site
names rather than changeable IP addresses.
Procedure
Step 1 Choose Advanced > Settings > Network > IP > H.323, and then set the parameters listed in
Table 3-4.
Table 3-4 H.323 parameters
Parameter
Description
Setting
Enable GK
Specifies whether the endpoint registers
with the GK.
This parameter is not selected
by default.

If this parameter is selected, when
your endpoint starts, it registers with
the specified GK. An endpoint that
registers with a GK can place calls to
remote sites using their IP addresses
or site numbers if the remote sites
also register with GKs. A GK must
be used to initiate a conference
attended by IP and integrated services
digital network (ISDN) sites.

If this parameter is not selected, your
endpoint does not register with the
GK. To call another endpoint through
H.323, your endpoint can only use
the called endpoint's IP address.
NOTE
If you select Enable GK, you must also set
GK registration mode, Site number, H.323
ID, and Password.


Do not connect outdoor cables directly to the TE60. If outdoor E1 lines (unbalanced) are
led indoors, surge protectors are required. Any questions, contact technical support
personnel.

The connection of E1 lines must comply with grounding specifications. For details, see A
E1/T1 Grounding Criteria.
A 4E1 interface card provides four balanced-output ports. If the TE60 has a 4E1 interface card
installed, connect the TE60 to a 4E1-line dedicated network.
The ports of a 4E1 interface card can be used for any of the four E1 lines. There is no
mapping between the ports and the four E1 lines on the local and the remote ends, so the lines
can be connected to any of the ports at the local and remote ends, as long as all the four lines
are connected.
3.2.1 Inserting a 4E1 Interface Card
To hold conferences over a 4E1 network, you must insert a 4E1 interface card into the
corresponding interface slot at the back of the TE60.
For safety reasons, insert the interface card only when the TE60 is powered off.
Figure 3-1 shows the appearance of a 4E1 interface card, for your reference only.

3.2.3 Setting 4E1 Parameters
If 4E1 lines are used for video communication, you must set 4E1 parameters such as the
account, password, clock mode, signaling mode, and sensitivity.
Prerequisites
Before setting 4E1 parameters, ensure that 4E1 lines are used by the TE60.
If the TE60 has a 4E1 interface card installed, the TE60 automatically detects the interface
card type and displays the corresponding configuration screen. For parameter details, contact
your network service provider.
Context
If 4E1 lines are faulty and if automatic backup is available, the endpoint uses the backup line
preferentially, and then reduces the conference rate automatically. The endpoint can perform
automatic backup, automatic rate reduction, or automatic rate increase in one second. During
the process, erratic display may occur on the video and noise may exist. After two seconds,
however, the video and the audio will be recovered and the conference rate remains
unchanged.

Connecting to one display device
The 1 MAIN OUT port is recommended. Using the default endpoint settings, a display
device connected to the 1 MAIN OUT port can show the local video, presentation,
remote controlled UI, captions, and combined pictures.

Connecting to two display devices
To show the video and presentation independently on two display devices, connect the
two display devices to the 1MAIN OUT and 2 PC OUT ports if you are using the TE60
and to the 1 MAIN OUT and 2 HDMI OUT ports if you are using the TE50 or TE40. A
display device shows the local video when connected to the 1 MAIN OUT port and
shows the presentation when connected to the 2 PC OUT port (or 2 HDMI OUT port).

VPM220 Cascading
The VPM220 provides 360°sound pickup and an optimal pickup range of six meters. In a
large conference room (of about 40 to 50 square meters) with only one VPM220, audio far
from the VPM220 becomes problematic; cascaded VPM220s can help alleviate this problem.
Dynamically cascading, connecting, or disconnecting VPM220s will not interrupt a
conference.
The TE40 and TE50 can be connected to only one VPM220 while the TE60 can be connected
to two cascaded VPM220s.
Figure 5-1 shows the cascading of VPM220s.

6.9 Managing Captions
You can create a caption on your endpoint. In addition, you can share the caption with remote
sites during a conference.
6.1 Experiencing a Dual-Stream Conference
During a dual-stream conference, two independent video stream channels, that is, the video
and the presentation, can be transmitted; furthermore, two channels of video from the local
site can be transmitted or two channels of video from a remote site can be received at the
same time.
6.1.1 Designating the Dual Streams
You need to choose the input sources and output destinations for the video and presentation.
Background
If multiple video-source devices are connected to the video input ports on the endpoint, you
can choose a channel of video as the source of the local video and another channel as the
source of the local presentation.
The endpoint adopts difference policies to deliver the video and presentation based on on-site
situations:

In single-screen display mode, if no presentation is shared during a conference, remote
sites view the conference video of the local site; if a presentation is shared, both the local
and remote sites view the presentation.

In dual-screen mode, the display device connected to the main output port delivers the
video while the display device connected to the auxiliary output port delivers the
presentation.

During the layout switch in combined picture or continuous presence mode, remote sites
can always view the conference video of the local site.
Selecting the Video Source
Choose Advanced > Settings > Video > Common Settings > Video Input. On the displayed
screen, set Video Source to a video feed.
Selecting the Presentation Source
Choose Advanced > Settings > Video > Common Settings > Video Input. On the displayed
screen, set Presentation Source to a video feed.
Selecting the Output Destinations for the Video and Presentation
By default, the endpoint comes with one display device and uses the main output port to
deliver both the video and presentation. If two display devices are connected to the endpoint,
you can set the endpoint to separately display the video and presentation on the two display
devices.

6.6.1 Conference Control for a Non-Chair Site
Non-chair sites have access to only four conference control functions: Request chair, Request
floor, View site, and Revoke chair.
The Revoke chair function is available only to the site that initiates or pays for a conference.
Viewing a Site
During a conference, the function to view a site is unavailable when the function to broadcast
a site or continuous presence is used.

You view the sites connected to their own MCUs or MCUs of the same level only.

You can choose to view a single site.

You can view continuous presence during a conference if the conference supports
Continuous presence .
During multipoint conferences hosted by standalone MCUs, the endpoint supports multiple continuous
presence views.
Request Chair
The conference chair site can use more conference control functions than other sites.
Only non-chair sites can request chair control rights when no chair site exists in a conference.
Audio-only sites cannot request chair control rights.
The conference access number is required when a site requests chair control rights. Obtain
this number from the SMC administrator or the calling party.
Request Floor
If a non-chair site wants to speak during a conference, the site can request the floor from the
chair site.
This function is available only when a chair site exists in the conference. After a site requests
the floor, the request is submitted to the chair site. The chair site can then determine whether
to give the floor to the site.

If the chair site gives the floor to the site, the site is broadcast, and all the sites, except
the chair site and the site given the floor, are muted.

If the chair site does not give the floor to the requesting site, the conference status
remains unchanged.
Revoke Chair
When chair control rights are revoked, no chair site exists in the conference. Sites in the
conference can then request to chair the conference.
Only the site that initiates or pays for the conference can revoke chair control rights.

6.6.2 Conference Control for the Chair Site
Only one site can chair a conference. Another site can chair the conference only after the
current chair site releases its chair control rights or the chair control rights is revoked.
The chair site has access to various conference control functions, such as viewing sites,
enabling or disabling voice activation, adding sites, setting continuous presence, releasing
chair control rights, ending the conference, and broadcasting sites.
View Site
The chair site has full access to view the participant sites in the conference except when the
endpoint is broadcasting sites in turn.

You can view any sites residing on the local MCU and MCUs cascaded to the local
MCU.

You can choose to view a single site or multiple sites in turn at preset intervals.

conference rate is 256 kbit/s
and the audio bandwidth is 64
kbit/s, the video bandwidth is
only 196 kbit/s. In this case,
the video quality is poor.
If the conference rate is lower than
256 kbit/s, set the audio protocol
to G.728 to reduce the bandwidth
used for audio transmission.
Only low video bandwidth is
available for your site because
the network is busy.
Do not initiate conferences during
network busy hours.
The quality of a network
connection device, such as an
optical fiber transceiver, is
poor. As a result, certain data
is lost during transmission.
Replace the related network
connection device.
Ask the remote site
administrator to perform a
local video loopback test. If
the video quality is good, the
video frame rate set at the

remote site to disconnect from the
conference, set the video frame
rate to a smaller value, and join
the conference again.

A E1/T1 Grounding Criteria
E1/T1 Grounding Criteria
Read the following grounding criteria carefully and comply with the relevant requirements
during the installation of the endpoint.
The grounding design of the telecom office (station) follows the principle of equalized voltage.
That is, the work grounding and the protection grounding (including the shielded grounding
and the surge protection grounding of the distribution frame) share a set of grounding
conductors.
When the E1 cable of the cabinet is over 7.5 m and the T1 cable of the cabinet is over 10 m, a
shielded cable and a shielded connector should be used and grounded.
When the E1 interface is connected to other devices using coaxial cables, the external shield
layers at the transmitting endpoint and receiving endpoint should be connected to the
protection ground at the same time. The dual in-line package (DIP) switch offers the possible
disconnection function at the receiving end.
Copper-core materials instead of aluminum materials should be used for the ground cable.
The plastic insulated copper wires with yellow and green insulation color should be used for
the protective ground cable. The protective ground cable should not exceed 30 m, and the
shorter the better. When the protective ground cable exceeds 30 m, the ground bar should be
rearranged.
In a balanced circuit, the joint of the E1 (T1) cable and the connector should be grounded
using the external shield layer (the grounding conductor) or an additional wire to ensure
normal reception and transmission in each E1 (T1) channel. In an unbalanced circuit, the
metal braid shield layer of the cable should be seamlessly connected to the coaxial connector.
When the E1 cable exceeds 30 m and the T1 cable exceeds 40 m, use the multi-point
grounding mode. In addition, connect the E1 cable to the ground at every 15 m and the T1
cable to the ground at every 20 m.
When the E1 or T1 cable is extended out of the office (station), the E1 or T1 cable should go
through the main distribution frame (MDF) attached with the security unit. The shield layer of
the E1 or T1 cable should be firmly connected to the protection ground of the MDF. The
security unit on the MDF should have the overvoltage protection, overcurrent protection, and
failure alarm functions. The maintenance personnel should check the equipment periodically
and replace the ineffective protection unit in time.
For questions about grounding the device, contact the device provider for technical support.

Terminology
This appendix provides the terms you will encounter in this administrator guide.
Numerics
1080i
1080i is the shorthand name for a format of high-definition video
modes. 1080 denotes the number of horizontal scan lines - also
known as vertical resolution - and the letter i stands for interlaced. In
the alternate format of high-definition video mode, known as 1080p,
the p would stand for progressive scan. 1080i is generally used in
place of 1440x1080, at a frame rate of 29.97 (30000/1001), while
1080p is usually used in place of 1920x1080 (full HD), at a frame
rate of 23.976 fps (24000/1001).
1080p
1080p is the shorthand name for a category of HDTV video modes.
The number 1080 represents 1,080 lines of vertical resolution (1,080
horizontal scan lines), while the letter p stands for progressive scan
(meaning the image is not interlaced). 1080p can be referred to as full
HD or full high definition although 1080i is also "Full HD"
(1920x1080 pixels). The term usually assumes a wide-screen aspect
ratio of 16:9, implying a horizontal resolution of 1920 pixels. This
creates a frame resolution of 1920×1080, or 2,073,600 pixels in total.
The frame rate in hertz can be either implied by the context or
specified after the letter p (or i), such as 1080p30, meaning 30 Hz.
2 panes
Users see two sites on one display device in two panes. The two
panes are of the same size. Each pane is about 1/4 of the screen. Use
2-pane as an adjective.
2CIF
2CIF defines a video with a resolution of 352 × 576 pixels and using
progressive scanning.
2SIF
2SIF defines a video with a resolution of 352 × 480 pixels and using
progressive scanning.
3 panes
Users see three sites on one display device in three panes. Use 3-pane
as an adjective.
4CIF
4CIF defines a video resolution of 704 ×576 pixels.
4SIF
4SIF defines a video with a resolution of 704 × 480 pixels and using
progressive scanning.

The number 720 stands for the 720 horizontal scan lines of display
resolution (also known as 720 pixels of vertical resolution), while the
letter p stands for progressive scan or non-interlaced. When broadcast
at 60 frames per second, 720p features the highest temporal (motion)
resolution possible under the ATSC standard. Progressive scanning
reduces the need to prevent flicker by filtering out fine details, so
sharpness is much closer to 1080i than the number of scan lines
would suggest.
broadcast (site)
All sites, except for the site being broadcast, view the site that is
broadcast. On the Broadcast Site screen, users can choose between
Broadcast Single and Broadcast in Turn.
broadcast single
(site)
Broadcast one specified site.
call absent (sites)
Place calls to all the sites that are on the site list but are absent from
the conference.
call site
Place a call to a site to add the site to the conference.
cascading
Multiple MCUs are connected in series at different layers to allow the
number of participants to expand beyond what a single MCU can
support. In cascading mode, an MCU in an upper layer can control an
MCU in a lower layer.
camera preset
Users can control a camera by zooming, panning, and tilting the
camera or changing the focus. Then, users can store this camera
position and assign a number to this position. This preset position is a
camera preset. During a conference, users can move the camera to a
camera preset by selecting the relevant number.
CIF
CIF (Common Intermediate Format), also known as FCIF (Full
Common Intermediate Format), is a format used to standardize the
horizontal and vertical resolutions in pixels of YCbCr sequences in
video signals, commonly used in video teleconferencing systems. It
was first proposed in the H.261 standard.
continuous
presence
A feature in multi-point conferencing that allows the video endpoint
to see images from multiple video endpoints at the same time. All
parties remain continuously visible or 'present' for the duration of the
call and the user can have control over the screen layout. Continuous
presence is better suited for team collaboration since it allows
participants to see the reactions (body language) of all participants,
not just the speaker.
delete site
Remove a site from the site list.

E Terminology
dual stream
During a conference, two channels of video streams can be sent or
received simultaneously. For example, one channel is used for
transmitting video (such as video captured by a camera) and the other
channel is used for transmitting presentation (such as a computer
desktop). The two channels of videos can be displayed on two
displays.
end conference
End a conference. In this case, all sites leave the conference.
full-duplex
A full-duplex, or sometimes double-duplex system, allows
communication in both directions, and, unlike half-duplex, allows
this to happen simultaneously. Land-line telephone networks are
full-duplex, since they allow both callers to speak and be heard at the
same time. A good analogy for a full-duplex system would be a
two-lane road with one lane for each direction.
G.711
G.711, also known as Pulse Code Modulation (PCM), is a very
commonly used waveform codec. G.711 uses a sampling rate of
8,000 samples per second, with the tolerance on that rate 50 parts per
million (ppm). Non-uniform quantization (logarithmic) with 8 bits is
used to represent each sample, resulting in a 64 kbit/s bit rate. There
are two slightly different versions; μ-law, which is used primarily in
North America, and A-law, which is in use in most other countries
outside North America.
G.722
G.722 is an ITU-T standard 7 kHz wideband speech codec operating
at 48, 56 and 64 kbit/s. It was approved by ITU-T in November 1988.
Technology of the codec is based on sub-band ADPCM
(SB-ADPCM).
G.728
G.728 is an ITU-T standard for speech coding operating at 16 kbit/s.
It is officially described as Coding of speech at 16 kbit/s using
low-delay code excited linear prediction.
give floor
After the chair site gives floor to a site, the other sites view and hear
the site. All the sites, except the chair site and the site that is given the
floor, are muted.
H.239
H.239 is an ITU-T recommendation from the H.32x Multimedia
Communications' macrofamily of standards for multimedia
communications over various networks. The H.239 recommendation
is titled "Role management and additional media channels for
H.3xx-series endpoints". Practical importance of this
recommendation is its setting forth a way to have multiple video
channels (for example, one for conferencing, another for

presentation) within a single session (call).
H.263
H.263 is a video codec standard originally designed as a low-bitrate
compressed format for videoconferencing. It was developed by the
ITU-T Video Coding Experts Group (VCEG) in a project ending in
1995/1996 as one member of the H.26x family of video coding
standards in the domain of the ITU-T. H.263v2 (H.263+) added
support for flexible customized picture formats and custom picture
clock frequencies. Previously the only picture formats supported in
H.263 had been Sub-QCIF, QCIF, CIF, 4CIF, and 16CIF, and the
only picture clock frequency had been 30000/1001 (approximately
29.97) clock ticks per second.
H.264
H.264/AVC/MPEG-4 Part 10 (Advanced Video Coding) is a standard
for video compression. The final drafting work on the first version of
the standard was completed in May 2003. H.264/AVC is the latest
block-oriented motion-compensation-based codec standard developed
by the ITU-T Video Coding Experts Group (VCEG) together with the
ISO/IEC Moving Picture Experts Group (MPEG), and it was the
product of a partnership effort known as the Joint Video Team (JVT).
The ITU-T H.264 standard and the ISO/IEC MPEG-4 AVC standard
(formally, ISO/IEC 14496-10 - MPEG-4 Part 10, Advanced Video
Coding) are jointly maintained so that they have identical technical
content. H.264 is used in such applications as Blu-ray Disc, videos
from YouTube and the iTunes Store, DVB broadcast,
direct-broadcast satellite television service, cable television services,
and real-time videoconferencing.
H.323
H.323 is a recommendation from the ITU Telecommunication
Standardization Sector (ITU-T) that defines the protocols to provide
audio-visual communication sessions on any packet network. The
H.323 standard addresses call signaling and control, multimedia
transport and control, and bandwidth control for point-to-point and
multi-point conferences.
half-duplex
A transmitting mode in which a half-duplex system provides for
communication in both directions, but only one direction at a time
(not simultaneously). Typically, once a party begins receiving a
signal, it must wait for the transmitter to stop transmitting, before
replying.
hang up (site)
Hang up a remote site and remove the site from the conference.
HD
Refers to a video system of higher resolution than standard-definition
(SD) video, most commonly at display resolutions of 1280×720
(720p) or 1920×1080 (1080i or 1080p, full HD). High definition
(HD) refers to an increase in display or visual resolution of television
formats (HDTV), high definition video (used in HDTV broadcasting,
digital film and computer HD video film formats), high definition
multimedia interface (HDMI), an all-digital audio and video interface
capable of transmitting uncompressed streams and other formats for
recording and transmitting visual and audio communications.
hide video
During a conference, a site can hide its video to prevent other sites
from viewing the video of the site.

intelligent mode
A video transforming mode, in this mode, cut the video first and then
stretch the video. Ensure that the aspect ratio of the video remains
unchanged. For example, to change a wide-screen video to a
narrow-screen video, crop the left and right edges of the wide-screen
video, and then stretch the video to full screen.
lock conference
(presentation)
After the chair site locks a conference and if site A is sharing
presentation, the other sites in the conference cannot share
presentation until site A stops sharing presentation.
lock site
(presentation)
After the chair site locks the presentation, only the site that is
currently sharing the presentation can continue sharing presentation.
Other sites cannot share presentation.
presentation
During a conference, the local site can share the content input by a
computer with remote sites, such as an excel file, a diagram, or a
presentation.
release chair
Pass the chair control to another site.
request chair
Request chair rights and become the chair site.
request floor
Request to speak. During a conference, users can request the floor
from the chair site.
revoke chair
When chair control rights are revoked, no chair site exists in the
conference. If the site that revokes the chair rights wants to become
the chair site, the site needs to request chair rights.
revoke
presentation
After the chair site revokes the presentation token, the relevant site
stop sharing the presentation.
S-Video
Separate Video[1], more commonly known as S-Video, also called
Y/C, and sometimes incorrectly [2] referred to as Super Video[3], is
an analog video signal that carries video data as two separate signals:
luma (luminance) and chroma (color). This differs from composite
video, which carries picture information as a single lower-quality
signal, and component video, which carries picture information as
three separate higher-quality signals. S-Video carries standard
definition video (typically at 480i or 576i resolution), but does not
carry audio on the same cable.
SIF
Source Input Format (SIF) defined in MPEG-1, is a video format that
was developed to allow the storage and transmission of digital video.
625/50 SIF format (PAL/SECAM) has a resolution of (360 or) 352 x

SVGA
Super Video Graphics Array or Ultra Video Graphics Array, almost
always abbreviated to Super VGA, Ultra VGA or just SVGA or
UVGA is a broad term that covers a wide range of computer display
standards. Originally, it was an extension to the VGA standard first
released by IBM in 1987. Unlike VGA—a purely IBM-defined
standard—Super VGA was defined by the Video Electronics
Standards Association (VESA), an open consortium set up to promote
interoperability and define standards. When used as a resolution
specification, in contrast to VGA or XGA for example, the term
SVGA normally refers to a resolution of 800 × 600 pixels.
UXGA
Ultra extended graphics array, supporting a maximum resolution of
1600 x 1200 pixels.
video
The video is generally output from the HD OUT 1 interface of an HD
video endpoint and is captured by a camera.
view single (site)
View any site.
view site
View any site. On the View Site screen, users can choose between
View Single and View in Turn.
voice activation
This function is used for discussion or arguing scenarios. The site

XGA
XGA, the Extended Graphics Array, is an IBM display standard
introduced in 1990. Today, it is the most common appellation of the
1024×768 pixels display resolution, but the official definition is
broader than that.
