Before setting the 3G parameters, ensure that the terminal license supports 3G networks. For details about how to check whether the terminal license supports 3G networks, see section

13.1.4 "Viewing the System Information."

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.

IP address

After enabling the 3G network, you can initiate an H.323 or SIP video conference using the terminal over the 3G network.

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.



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.

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.

For details about how to enable the H.239 mode, see section 6.3 "Setting Conference Parameters." By default, the H.239 mode is enabled on the terminal.

The H.239 mode supports Presentation and Live.



Presentation: When the video is switched, the presentation remains unchanged. This mode is used when the presentation carries images, such as slides.



Live: The presentation viewed by each site is switched along with the video. This mode is used when the presentation carries videos.

During a conference, you can create a caption, and then overlay the caption on the video sent by the local site. The caption can be overlaid on the top, in the middle, or at the bottom of the video.

The terminal supports T.140 and non-T.140 captions. Table 9-1 describes the differences between these two types of captions.

9 Captions

Table 9-1 Differences between T.140 and non-T.140 captions

Non-T.140 Caption T.140 Caption

A non-T.140 caption will be superimposed on the local video.

SIP and H.323 terminals can send and receive captions.

No restriction is imposed on the terminals that send or receive non-T.140 captions.

Non-T.140 captions can be sent only from terminals in a conference, and cannot be sent from the ResourceManager that is the videoconferencing management software.

A T.140 caption will be sent to remote sites and displayed on the remote displays without being superimposed on the local video.

Only H.323 terminals can send and receive captions.

If a T.140 caption is shared, both the sending and receiving parties in a conference must support T.140 captions. Otherwise, a terminal that does not support T.140 captions cannot receive the shared T.140 caption.

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.

Step 1 Choose Settings > Caption, and then set the parameters listed in Table 9-2.
