Introduction 1-1 Product Overview The DVG-G5402SP Wireless VoIP Gateway is designed to carry both voice and facsimile over the IP network and wirelessly share Internet access. It uses the industry standard SIP call control protocol so as to be compatible with free registration services or VoIP service providers systems. As a standard user agent, it is compatible with all common Soft Switches and SIP proxy servers. While running optional server software, the gateway can be configured to establish a private VoIP network over the Internet without a third-party SIP Proxy Server. The gateway can be seamlessly integrated into an existing network by connecting to a phone set and fax machine. With only a broadband connection such as an ADSL bridge/router, a Cable Modem or a leased-line router, the gateway allows you to use voice and fax services over IP in order to reduce the cost of all long distance calls. The DVG-G5402SP is also an 802.11b/g wireless access point. Allow wireless clients to connect to it and share your broadband Internet connection. A built-in 4-port switch makes it possible to connect up to 4 Ethernet-enabled computers or devices to also share your Internet connection. The wireless voip gateway can be configured a fixed IP address or it can have one dynamically assigned by DHCP over PPPoE. It adopts either the G.711, G.726, G.729A or G.723.1 voice compression format to save network bandwidth while providing real-time, toll quality voice transmission and reception.

D-Link Systems, Inc. 12 DVG-G5402SP Users Manual SETUP 2-1-3 Wireless Settings This section instructs you how to setup your wireless network on the Gateway device. Setup Hint:

1. Every device in the same wireless network must use the same SSID. 2. 3. Make sure security used by every device in the same wireless network is compatible with the wireless To avoid wireless network overlap, a specific and different channel is needed. AP. 2-1-3-1 Basic Settings Wireless Settings Basic Settings Enable Wireless LAN Interface: Enable wireless basic settings on LAN interface. Band: The Gateway can operate in 2.4GHz ISM band with different speed of wireless connection, Select the wireless band of your network. 2.4GHz (B) - Allow all 802.11B compliant wireless devices to associate with the wireless AP. 2.4HGz (G) - Allow all 802.11G compliant wireless devices to associate with the wireless AP. 2.4GHz (B+G) - Allow a mix of both IEEE802.11b and IEEE802.11g compliant wireless devices to associate with the wireless AP. Associated Clients: Click on Show Active Clients button, you can see all clients associated to the AP. SSID: SSID is the name of your wireless network. All wireless-equipped devices share the same SSID to communicate with each other. It must be unique to identify separated wireless network. For security, you should change the default SSID to a special ID. Channel Number: Select a clear and appropriate channel for your wireless network. A device on your wireless network must use a specific channel to transmit and receive data. If wireless network has overlap, change a different channel number. D-Link Systems, Inc. 13 DVG-G5402SP Users Manual SETUP 2-1-3-2 Advanced This section introduces advanced configuration for the wireless access point. If you are not familiar with the following functions, keep the default parameters. In some cases, incorrect settings may reduce wireless performance. Wireless Settings Advanced Authentication Type: Select the type of authentication. Open System - Any wireless client can associate with the wireless access point but the client must have the same WEP key to exchange data. Shared Key - Wireless clients must have the same WEP key to associate with wireless access point and exchange data. Auto Auto-detect the authentication type. Fragmentation: A packet can be fragmented into small units to pass over a network medium that can not support the original packet size. If you encounter a busy network, a lower value of Fragment Threshold could improve performance. If the traffic flows are not very busy, a higher Fragment Threshold provides good network performance. In most case, keeping the default value=2346 is recommended. RTS Threshold: RTS Threshold is a mechanism to implement in collision avoidance. In a large wireless network, two stations do not hear each other but can hear wireless access point. When the two send data to Access Point at the same time, it may result in data collision and a loss of messages for both wireless stations. In most case, keeping the default value=2347 is recommended. Beacon Interval: The default value is 100. The Beacon Interval indicates the frequency interval of target beacon transmission time which can be found in a packet body. The Gateway transmits the beacon packet to help a wireless client to identify the existence of nearby access point. If the beacon intervals are too long, it would be hard to access the network. If the beacon intervals are too short, the resources would be wasted. D-Link Systems, Inc. 14 DVG-G5402SP Users Manual SETUP Data Rate: IEEE802.11b supports Auto, 1, 2, 5.5, 11 Mbps signaling rate. EEE802.11g supports Auto, 6, 9, 12, 18, 24, 36, 48, 54 Mbps signaling rate. The data rate will change automatically to get better throughput depending on range and environment of the wireless network. Preamble Type: Preamble Type defines the length of the preamble which sends out with a packet format. Specify an appropriate preamble type for your network, if you do not know which one to select, keeping the default setting Long Preamble is recommended. Broadcast SSID: Disable the SSID broadcast. This is to prevent users from seeing your wireless network. IAPP: IAPP (Inter Access Point Protocol) provides the communication among access points in order to support mobile station roaming mechanism from one access point to another. 802.11g Protection: In 802.11b/g Mixed mode, it can be used for protection mechanism. The 802.11g OFDM traffic can keep the connection stable and avoid 802.11b interference. But that might cause the poor throughput. RF Output Power: You can adjust the percentage of power 100, 50, 25, 10, 5 of your Gateway to change the coverage of wireless network. Keep the default value, 100% to reach full range. Turbo Mode: The AP would identify the wireless stations chipset to improve the performance. 2-1-3-3 Security Settings This section introduces you different ways of wireless security you can setup. It is important to enable secure algorithm to protect your data from eavesdropping by unauthorized wireless users.

Configuring the Gateway through IVR VoIP transmits voice data (packets) via the Internet, hence the condition and status of the network environment is relatively important to the telecommunications quality. If any one of the parties involved in VoIP communications has insufficient bandwidth or frequent packet loss, the telecommunication quality will be poor. Therefore, excellent telecommunication can only happen when the gateways are connected to the Internet and when the network environment is stable. Preparation 1. Connect the power supply, telephone set, telephone cable, and network cable properly as described 2. 3. 4. in Chapter 2. If a static IP is provided, confirm the correct IP settings of the WAN Port (IP address, Subnet Mask, and Default gateway). Please contact your local Internet Service Provider (ISP) if you have any question. If you are using ADSL (PPPoE) for your network connection, confirm the account number and password. If you intend to operate the gateway under NAT, the IP range of Gateway WAN Port and LAN Port IP Address should not be the same in order to avoid phone failures. Basic Setup The gateway provides two setup modes:

1. Telephone IVR Configuration Mode 2. Browser Configuration Mode IVR configuration provides basic query and setup functions, while browser configuration provides full setup functions. 3-1 IVR (Interactive Voice Response) The gateway provides convenient IVR functions. Users are able to get query and setup the gateway with a phone-set and function codes without turning on the PC. Note: When finishing the setup, make sure the new settings are saved. This will enable the new settings to take effect after the system is restarted. Instructions FXS Port: Connect to telephones. To access IVR mode, passwords should be entered, * * password #. Alphabets to digits conversion information is provided in the PPPoE Character Conversion Table. (Refer to Page??) When correct IVR passwords are entered and accepted, an indication tone can be heard indicates the system is in IVR setup mode. Enter function codes to check or configure the gateway. (Please refer to page 43 for function codes). Example: If your password is 1234, enter * (star) * (star) 1 2 3 4 # (pound), and now you are entering IVR setup mode. Next, enter a function code to check or configure the gateway. If your password is admin, enter * (star) * (star) * (star) 41 44 53 49 54 # (pound). Please refer to the IVR Functions Table (page 43) for available functions and codes. D-Link Systems, Inc. 68 DVG-G5402SP Users Manual Gateway Configuration-IVR Once the setting or query has been completed, you can hear a dial tone. Use the same procedure to make a second query or setting. To exit IVR mode, simply hang up the phone.
