H3C VG is a voice gateway device (hereinafter referred to as VG). It is developed by H3C Technology Co., Ltd. as a new generation of voice and fax access equipment for various sectors and SOHO (small office and home office).

The VG is designed to access voice and fax signal, and convert the analog voice and fax signal to digital signal, then packetize the digital signal into IP packets, and send the IP packets to the IP network through an Ethernet interface at the network side. Additionally, some models, such as VG 10-40/10-41, can implement broadband access of digital service, and provide an Ethernet interface at the user side to connect a PC or a LAN.

The VG is cost-effective, for it integrates various IP telephone features, such as voice over IP (VoIP), fax over IP (FoIP), call control, resource management, and maintenance management, provides multiple coding/decoding modes, and supports dynamic address acquisition.

The VG is compliant with H.323 of ITU-T and guarantees quality of voice and fax data transmission over the IP network through high-performance DSP chips, coding/decoding algorithms with a high compression ratio, echo cancellation, mute compression, comfortable noise, jitter prevention, and relevant security and QoS features.

The VG supports fast and non-fast connection to implement outband transmission of the DTMF (dual tone multifrequency) code and provide busy tone detection, abbreviated dialing, private lines, outgoing prefix, and some special services of program-controlled switch (such as do-not-disturb, call forward on busy, alarm call, and multi-line group access).

At present, the VG provides Ethernet interfaces to connect with LAN and WAN, and FXS (foreign exchange station) interfaces and FXO (foreign exchange office) interfaces to connect with ordinary telephone sets or PBX (private branch exchange).

Apart from providing SOHO users with IP telephone and fax services, the VG can implement simultaneous transmission of voice and data by connecting with LAN through Ethernet interfaces and thus make better use of the resources.

Chapter 2 Getting Started with Configuration

2.1 Connecting Hardware

For a VG with two Ethernet interfaces:

The default IP address of the WAN interface is 192.168.192.1, with a subnet mask of 255.255.255.0.

The default IP address of the LAN interface is 192.168.193.1, with a subnet mask of 255.255.255.0.

For a VG with only one Ethernet interface:

The default IP address of the ETH interface is 192.168.192.1, with a subnet mask of 255.255.255.0.

Connect the Ethernet interface WAN or ETH with a PC through a network, and configure the IP address of the PC on the same network segment as the default IP address of the VG, and use the ping command to check the connection between the VG and PC.

& Note:

Users can modify the IP address of an Ethernet interface through Web configuration. Once the IP address is modified, the default IP address will be deleted automatically.

2.2 First Login

Open the explorer (IE5.0 or later recommended) and input the IP address 192.168.192.1 in the address bar. Press <Enter>, and a language selection page will appear, as shown in Figure 2-1.

Figure 2-1 The language selection interface

Select a language, and click <Enter> to enter the configuration page.

2.3 Interface Introduction

2.3.1 System Information Page

The system information page displays basic system information about the VG.

Figure 2-2 The system information page

2.3.2 List Display Page

Figure 2-3 The list display page

The list display page consists of three parts: navigation bar, data display area and operation button bar.

I. Navigation bar

The navigation bar is located at the uppermost part of the configuration area and used to navigate to the data you want to view. Click the drop-down list box at the top left corner to adjust the number of data displayed on each page. If one page cannot display all data, you can turn to another page by clicking <<<Previous> or <Next>>> at the top right corner.

II. Data display area

The data display area is located in the middle of the configuration area and displays the content of data in a table.

l The first column of the table is a check box for deletion option. If the check box is grey, it indicates you cannot delete this entry.

l On the last column is a property setting button. Press this button to enter the page for setting the properties of the current data. A user can both view details of the data on this page and modify some of properties (refer to the section 2.3.3 “Configuration Item Page”). If this column is not available in the table, it means the data in the table cannot be modified. If a data entry has no modification button, it means this data entry cannot be modified.

l The other columns of the table display the data information.

III. Operation button bar

The operation button bar is located at the bottom of the configuration area. The list display page supports the following operations:

<Select All>: Selects all the data entries displayed in the current page for the purpose of deletion. Once clicked, the button will change automatically to <Cancel All> for canceling selection of all the entries. When <Cancel All> is clicked, the button will return to <Select All> automatically.

<Del Select>: Deletes the selected data entry (entries). If no data entry is selected, a dialogue box will pop up to prompt you to select a data entry.

<Refresh>: Asks the VG for the latest data of the current page.

2.3.3 Configuration Item Page

The third type of page is a property setting page, which displays in a table the properties you need to set as well as their related information. You can use the input box or drop-down list box to set the properties. This kind of page is usually used to create, modify and view property configuration.

Figure 2-4 The configuration item page

A property setting page consists of two parts: property setting table and operation button bar.

I. Property setting table

A property setting table contains four columns:

The first one indicates the name of the property.

The second one is a column for inputting a value for the property. There are two means available for inputting a property value: direct typing in a text box and selecting from a drop box.

In some cases two properties are associated. For example, when property A is configured, property B will be made invalid. In such a case, the setting page will perform an automatic check when A is being configured. If A is configured with a value that will make B invalid, the setting page will hide B automatically or turn the input box of B into a disabled state (in grey), making it impossible for a user to input a value.

Besides, for some complex properties, such as the fax service property of the POTS (plain old telephone service) entity, a hyperlink is provided in the input column. Users can click this hyperlink to enter the configuration page.

Caution:

Except the “Voice Subscriber Line Description Information”, no data can contain “?”, space or two-byte character (such as Chinese), or the system will display an error prompt.

The third column describes the range of the property values. This description consists of two parts. The first part indicates the type of data you can input, including digital and string. The second part specifies the size of data. It refers to a length when a string is input and a range when digitals are input. For the string type, if it is 0, it means you are allowed not to input any value for this property. Numbers [1-10] means that you must input a number from 1 to 10 inclusively.

The fourth column is a link for detailed help information about the property. Click the help icon in this column to bring up the current property information.

II. Operation button bar

The operation button bar is located at the bottom of the configuration area. The property setting page supports the following operations:

<Execute>: Submits the configuration data of the current page to the Web server (VG).

Caution:

l Check the validity of each property value before submission.

l If an invalid property value is input, the system will display alarm information, and the data will not be submitted for processing.

l If an error occurs when the VG is performing configuration, an error prompt page will appear to indicate the cause, but the valid data submitted simultaneously are still processed as usual.

l If the configuration is successful, it will return to the previous page of the current configuration node (if there is no previous page, the current page remains.) For example, after the POTS entity is configured successfully, it will return to the POTS entity list display page. If global configuration of voice is successful, it will return to the page for global configuration of voice, because this page has no previous page.

<Reset>: Cancels the modification made by the user to the values in the property input box or drop-down list box.

<Refresh>: Asks the VG for the latest data of this current page. A configuration modification page contains this button, while a newly created page does not.

<Return>: Returns to the previous page.

Caution:

l A list display page, property setting page and configuration error alarm page support return operation, which means to return to the previous page.

l The page classifications and descriptions above are applicable to most pages, but some special pages, such as a configuration wizard page, may be a little different from what have been described. Please refer to the description of specific pages.

Return to section 3.1 “Web Configuration Overview”.

3.2.6 Fax Service Configuration

Step	Operation	Description	Remarks
Advanced configuration
-	Configure fax ECM mode	A fax machine that adopts ECM has the error correction function and can provide ARQ (automatic repeat request) and transmit fax packets in the HDLC frame format. In contrast, a fax machine that adopts a mode (supported) other than ECM has no error correction function, and transmits fax information in the binary format. ECM is applicable to fax only when the fax machines at both ends support ECM and the gateway adopts ECM as well. Related command: fax ecm (voice entity view).	Optional
-	Configure non-standard fax facilities	In ordinary fax applications, the fax terminals of both parties negotiate through standard facilities (such as V.17 or V.29 rate) by default, that is, they send no NSF (non-standard facilities) message frame. In some cases (such as encrypted fax), non-standard facilities become very important to fax communication. Therefore in such cases, fax terminals of both parties exchange NSF message frames to start the negotiation, and then negotiate on other fax facilities for communication. Related command: fax nsf-on (voice entity view).	Optional
-	Configure fax rate	If the fax baudrate is set to a value other than “disable” and “voice”, rate negotiation is performed preferentially through the fax protocol corresponding to this rate. The rate configured here is an allowed maximum rate instead of a specified rate in use. Related command: fax baudrate (voice entity view).	Optional
-	Configure fax training mode	Local training mode means that the gateways join in the rate training between the fax machines at two ends. In this mode, the training is first performed at the two ends respectively (that is, between the receiving fax machine and the receiving gateway, and between the sending fax machine and the sending gateway). Then the receiving gateway sends the training result of the receiving party to the gateway of the sending party, and the gateway of the sending party determines the final packet transmission rate according to the training results of the two parties. Related command: fax train-mode (voice entity view).	Optional
-	Configure energy level of sending fax gateway carrier	The default energy level of sending gateway carrier applies to most cases. If the faxing fails when other configurations are correct, you can try adjusting the energy level of sending gateway carrier. The smaller the energy level, the larger the energy. Related command: fax level (voice entity view).	Optional
-	Configure fax protocol	The VG supports two fax start modes: H.323 negotiation start mode and VG negotiation start mode, corresponding respectively to fax protocols H.323-T.38 and T.38. Moreover, the VG can provide transparent transmission fax through two configurations. 1) Configuring the fax protocol to PCM. 2) Configuring the two-party voice coding/decoding negotiation to G.711 and “Fax Baudrate” to “disable” (disable fax forward), and disabling mute detection (VAD) to prevent fax failure. This mode is applicable to transparent transmission interworking with other devices. Related command: fax protocol (voice entity view).	Optional
-	Configure the number of high speed redundancy packets sent via T.38	The VG supports control on high speed and low speed redundancy packets. Increasing the number of redundancy packets can improve reliability of network transmission and reduce the trouble caused by packet loss. But too many redundancy packets will largely increase bandwidth utilization, and affect fax quality gravely if the bandwidth is small. Therefore, the number of redundancy packets should be based on network bandwidth. This parameter is available when [Fax Protocol] is set to “h323-t38” or “T.38”. Related command: fax redundancy hb-redundancy (voice entity view).	Optional
-	Configure the number of low speed redundancy packets sent via T.38	This parameter is available when [Fax Protocol] is set to “h323-t38” or “T.38”. Related command: fax redundancy lb-redundancy (voice entity view).	Optional
-	Configure fax Passthrough mode	When the [Fax Protocol] is set to “pcm”, you should set a voice coding/decoding rate for fax transparent transmission. Related command: fax protocol pcm (voice entity view).	Optional
-	Configure fax transmission format	When the T.38 protocol is applied, the RTP mode (the corresponding parameter is rtp) is often used. To interwork with the VocalTec gateway, set the VT mode (the corresponding parameter is vt). Related command: fax support mode (voice entity view).	Optional

3.2.7 Voice Subscriber Line Configuration

Step	Operation	Description	Remarks
Basic configuration
1.	Modify voice subscriber line parameters	Select [Voice/Phone/Line] in the directory tree, and click the button in the <View/Modify> column in the configuration page to set voice subscriber line parameters.	Optional
2.	Configure description	Describe the voice subscriber line. Related command: description (voice subscriber line view).	Optional
3.	Configure comfortable noise	When VAD is enabled for a voice entity, mute intervals may exist during the voice conversation. You can use this command to produce proper background noise to fill the mute intervals. Related command: cng-on (voice subscriber line view).	Required
4.	Configure a private line number	If you have configured a private line number, the VG will automatically originate a call to this configured number after you pick up the phone (no other operation is needed). Related command: private-line (voice subscriber line view).	Optional
5.	Configure dial timeout time	Dial timeout time refers to the timer interval during which the system waits for a user to dial the next digit. When a user dials a digit, this timer is reset. This process is repeated until all digits are dialed. If timeout occurs before dialing is finished, the user will be prompted to hang up and the dialing is ended. Related command: timer dial-interval (voice subscriber line view).	Optional
6.	Configure FXO port binding	Specify the FXO port to be bound with the current FXS port. After being bound, an FXO port can be used by the corresponding FXS port only. After an FXS-FXO binding is created: l When a call is sent from the FXS port, the bound FXO port has the priority to direct it. l When the FXO receives a call from the PSTN, it directly sends it to the bound FXS port through the dedicated line. Related command: bind (voice subscriber line view).	Optional
Advanced configuration
-	Configure echo cancellation	During conversation, your voice is repeated for the line reason and returned to your receiver. This is called echo. The cause is leaking of analog voice signals to your own receiving path. You can solve the echo problem in conversation to some extent through the echo cancellation function provided by the VG. Related command: echo-canceller enable (voice subscriber line view).	Optional
-	Configure echo cancellation duration	Echo duration means the interval from the time a user makes an original sound to the time the echo is heard. The VG deals with echo cancellation according to this parameter. Related command: echo-canceller tail-length (voice subscriber line view).	Optional
-	Configure voice input gain	When attenuation of voice signal on a line is large, this command can be used to properly increase voice input gain. Related command: receive gain (voice subscriber line view).	Optional
-	Configure voice output gain	When the power of voice signal on the output line is small, this command can be used to increase proper voice output attenuation to meet the signal requirements of the output line. Related command: transmit gain (voice subscriber line view).	Optional
-	Number of the calling number transform rule table	This number is used to bind the calling number transform rule table with a voice subscriber line. Related command: substitute calling (voice subscriber line view).	Optional
-	Number of the called number transform rule table	This number is used to bind the called number transform rule table with a voice subscriber line. Related command: substitute called (voice subscriber line view).	Optional

Basic configuration
1.	Inquire voice GK client status	Select [Voice/GK Client/GK Client Status], and the information of start status and registration status is listed in the configuration page.	Optional
2.	Configure GK client parameters	Select [Voice/GK Client/GK Client] in the directory tree, and set GK client parameters in the configuration page.	Optional
3.	Configure a gateway alias	This parameter is used by the gateway to register and identify a VG in the GK Server. A gateway can have only one alias, and a new alias will override the old one. Related command: gw-id (voice GK view).	Required
4.	Configure a gateway source address	If a source IP address is configured for the VG (this is also referred to as source address binding), all the packets must use this unified source address, no matter which physical interface the voice IP packets are sent out from. Since the transmitted voice IP packets contain a unified and definite source address, packet filtering becomes very simple, making firewall control easier. Related command: gw-address (voice GK view).	Required
5.
