Product Overview
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 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.

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.

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.

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.
