DVG-G5402SP User’s Manual Product Overview

D-Link Systems, Inc. 4

1. 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 IPin 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.

2-1 SETUP

2-1-1 WAN Settings

WAN (Wide Area Network) Settings are settings that are used to connect to your ISP (Internet Service

Provider). The WAN settings are provided to you by your ISP and often times referred to as "public settings".

Please select the appropriate option for your specific ISP.

IP Configuration (Setting WAN Port)

There are five methods of obtaining a WAN port IP address:

1. Static IP

2. DHCP, which means a Dynamic IP (Cable Modem)

3. PPPoE (dial-up ADSL)

4. PPTP

5. BigPond (for Australia only)

Methods for using DHCP and PPPoE for obtaining an IP address may vary. If you are not familiar with

creating a network connection, please contact your local ISP.

After selecting the suitable option, click Accept at the bottom of the screen to save the settings.

You need to save the changes and restart the gateway to make the changes active. Saving the settings:

Click MAINTENANCE and select Save/Restart in System from the left menu. Tick Save Settings and

Restart, then click Accept. Wait for about 40 seconds before the gateway obtaining an IP address by the

method you selected.

Note: When the system has obtained a new IP address, and you are using a WAN port to enter the Web

Configuration Screen, the new IP address has to be used before you can get connected to the gateway.

The same principle applies to the next two settings.

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. To avoid wireless network overlap, a specific and different channel is needed.

3. Make sure security used by every device in the same wireless network is compatible with the wireless

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.

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.

DVG-G5402SP User’s Manual SETUP

D-Link Systems, Inc. 15

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 station’s 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.
