3.3.7 "Setting Firewall Parameters." Their functions, however, are different. The ports in this section are

used for network diagnostics and the ports in section 3.3.7 "Setting Firewall Parameters" are used for

calling.

Step 2 Save the settings.

3.4 Configuring the 3G Network

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

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.

When you insert or remove a data card, the following icons appear on the upper right corner

of the screen:

indicates that a data card has been removed, or the network connection of the data

card is faulty.

3.4.2 Setting 3G Parameters

To set the terminal's 3G parameters, do the following:

Step 1 Choose Settings > Network > 3G > 3G Settings, and then set the parameters listed in Table

3-9.

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 When the terminal is connected to a 3G network in PPP dial-up mode, the

n mode

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.

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.

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.

7.3.12 Setting the Continuous Presence

The continuous presence function is used to display the videos of two or more sites on the

same monitor simultaneously. The number of sites whose videos are displayed and the layout

of the videos vary according to continuous presence modes.

This function is available only when continuous presence resources have been reserved for the

conference.

To set the continuous presence, do the following:

Select a pane. From the drop-down list box in the displayed dialog box, select the site whose

video is to be displayed in the pane. Then select OK.

If a site already exists in the pane selected, the new site will replace the original site.

You can select Delete All to delete all the sites in the continuous presence.

7.3.13 Enabling and Disabling Voice Activation

The voice activation function is used during ongoing discussions in the conference. The site

with the loudest voice is viewed by the other sites in the conference.



The videoconferencing system sets a threshold based on the sensitivity selected. If the

volume of one or multiple sites exceeds the threshold, the video of the site with the

highest volume is broadcast.



If no site exceeds the threshold, the conference status remains unchanged.

7.3.14 Releasing Chair Control Rights

A non-chair site can request chair control rights only after the chair site releases the chair

control rights.

For a non-chair site, the following four conference control functions are available: requesting

chair control rights, requesting the floor, viewing sites, and revoking chair control rights. The

chair site, however, has all the conference control rights.

The function of revoking chair control rights is available only to the site that initiates or pays for the

conference.

conference. You can add a site from the address book or create a new site.

7.3.17 Extending a Conference

If a conference is estimated not to be complete by the scheduled time, the chair site can

extend the conference by selecting Extend Conference.

Before extending a conference, the chair site needs to ensure that the videoconferencing

resources and the account balance are sufficient. To increase the chances of success, the chair

site should not extend the conference too long at a time. It is recommended that the chair site

extends the conference by 30 minutes at a time, and this can be done multiple times if

necessary.

7.3.18 Ending a Conference

If a conference is complete before the scheduled time, the chair site can end the conference in

advance by selecting End Conference.
