3.4.1 Inserting a 3G Data Card
To use the terminal for video communications over a 3G network, a 3G data card must be
inserted into the terminal's USB port.
The 3G data card used with the terminal must be provided by Huawei. For details, contact the supplier.
If a 3G data card has been inserted and if the license of the terminal provides 3G data card
functions, the terminal performs detection as follows:
- If the data card is a designated Huawei data card, the terminal detects it automatically,
and a message appears on the screen indicating that a data card is available.
- If the data card is not a designated Huawei data card, the terminal fails to detect it, and a
message appears on the screen indicating that no data card is available.
The terminal supports only one 3G data card at a time. If multiple 3G data cards are inserted,
the terminal uses only the first data card that is ready and does not use the others.

Table 3-9 3G parameters
Parameter Description
Enable 3G
network
After enabling the 3G network, you can initiate an H.323 or SIP video
conference using the terminal over the 3G network.
IP address
type
This specifies the mode for obtaining an IP address. The default value is
Dynamic. It is recommended that you use the default value.
- Dynamic: The terminal obtains an IP address dynamically and
automatically from the network.
- Static: The terminal uses an assigned IP address to connect to a specific
server.
IP address - If IP address type is set to Dynamic, the IP address assigned by the
server is displayed in this text box only after a Point to Point Protocol
(PPP) connection is established successfully. After being registered with
the GK using the assigned IP address, the terminal can call remote sites
using the relevant numbers, names, or IP addresses over the 3G network.
- If IP address type is set to Static, you can enter the IP address
manually.
Authenticatio
n mode
When the terminal is connected to a 3G network in PPP dial-up mode, the
authentication mode can be set to PAP or CHAP to prevent the access by
unauthorized users. The default value is CHAP. It is recommended that
you use the default value.
- If you set the authentication mode to password authentication protocol
(PAP), the user name and the password are transmitted over the network
using plaintext. If the user name and the password are captured during
transmission, the network security is at great risk. Therefore, you can use
the PAP mode when the network security requirement is comparatively
lower.
- If you set the authentication mode to the Challenge-Handshake
Authentication Protocol (CHAP), only the user name is transmitted over
the network. Therefore, this authentication mode provides a higher
security level than the PAP mode. In CHAP authentication mode, each
inquiry message for authentication is unpredictable and unique,
preventing recurring network attacks.

6.4 Setting Up an H.239 Dual-Stream Conference
During an H.239 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.
If the license on the terminal does not support H.239, the terminal can receive presentation, but cannot
share presentation.
6.4.1 Designating the Dual Streams
Input sources and output destinations for the video and presentation must be chosen.
Choosing Input Sources
If multiple video-source devices are connected to the video input interfaces of the terminal,
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 priority of the video is higher than that of the presentation, as shown from the following
aspects:
- After a conference is initiated, the remote sites view the video of the local site before the
presentation.
- During the layout switch in continuous presence mode, the remote sites can always view
the video of the local site.
Choosing Output Destinations
During an H.239 dual-stream conference, if local video and presentation and remote video
and presentation exist simultaneously and if multiple monitors are used at the local site, you
can set the output interfaces for the videos and presentations as required.
6.4.2 Enabling the H.239 Mode
After enabling the H.239 mode, the video and the presentation can be sent simultaneously
during a conference.

- Setting the number of anonymous sites: Set the number of anonymous sites when
initiating a conference. Set numbers of anonymous sites of all types as listed in Table 6-1,
for example, Anonymous H.323 sites.
- Setting the authentication password: Set the Conference control password when
initiating a conference. This password can serve as the authentication password, which
an anonymous site needs to enter to join an authentication conference. If the Conference
control password is left blank, anonymous sites can join the conference without
entering any password.
- Obtaining the access number of the authentication conference: After the authentication
conference is initiated, a terminal can obtain the access number from the message which
is displayed when the terminal requests chair control rights successfully; the chair site
can also obtain the access number by choosing Diagnostics > Status > Conference.
Anonymous sites can obtain the access number and the authentication password from the
chair site using other methods.
- Joining the authentication conference by anonymous sites: Anonymous PSTN sites can
join the conference by calling the access number of the audio authentication conference
and anonymous IP sites can join the conference by calling the access number of the
video authentication conference.
To join an authentication conference, do the following:
Step 1 Check the necessary resource preparations using the following methods:
- From the chair site: Check that the anonymous site resources are available in the
conference to be called, and the access number of the video or audio authentication
conference and the authentication password have been obtained.
- From the local site: Check that the site has been registered with the GK.
Step 2 Press on the remote control to display the Call screen.

cannot be sent from the
ResourceManager that is the
videoconferencing management
software.
If both the sending and receiving parties in a
conference support T.140 captions, a T.140
caption can be sent using any of the following
methods:
- Sending the caption from the chair site
- Sending the caption from the ResourceManager
NOTE
Captions can be sent from either party in a point-to-point
call.
The terminals' software is different from each other. Therefore, you may need to set only
certain parameters instead of all of them when you prepare a caption.

If the conference rate is lower than
256 kbit/s, it is recommended that
you set the audio protocol to
G.728 to reduce the bandwidth
used for audio transmission.
Low video bandwidth is
available for the local site
because the network is busy.
Try to avoid initiating a
conference when the network is
likely to be busy.
Certain data is lost during
transmission, because the
quality of a network
connection device (such as an

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.
G
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 a 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.

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 terminals". 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.261 H.261 is a 1990 ITU-T video coding standard originally designed for transmission
over ISDN lines on which data rates are multiples of 64 kbit/s. It is one member of
the H.26x family of video coding standards in the domain of the ITU-T Video
Coding Experts Group (VCEG). The coding algorithm was designed to be able to
operate at video bit rates between 40 kbit/s and 2 Mbit/s. The standard supports two
video frame sizes: CIF (352x288 luma with 176x144 chroma) and QCIF (176x144
with 88x72 chroma) using a 4:2:0 sampling scheme. It also has a
backward-compatible trick for sending still picture graphics with 704x576 luma
resolution and 352x288 chroma resolution (which was added in a later revision in
1993).
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.
