DVG-N5402GF User’s Manual Product Overview

1. Introduction

1-1 Product Overview

The DVG-N5402GF 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 VoIP Router can be configured to establish a private
VoIP network over the Internet without a third-party SIP Proxy Server.

The DVG -N5402GF 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 VoIP Router allows you to use voice and fax services over IP in order to reduce the cost of all long
distance calls.

The DVG-N5402GF is also an 802.11b/g/n 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 DVG-N5402GF can be configured a fixed IP address or it can have one dynamically assigned by DHCP or
PPPoE. It adopts either the G.711, G.726, G.729A, G.723.1 or iLBC voice compression format to save network
bandwidth while providing real-time, toll quality voice transmission and reception.

3-2-4 Advanced Wireless

3-2-4-1 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.

ADVANCED -> Advanced Wireless -> Advanced

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.

RF Output Power: You can adjust the percentage of power 100, 50, 25, 10, 5 of your VoIP Router to
change the coverage of wireless network. Keep the default value, 100% to reach full range.

ADVANCED → Advanced Network → NAT Traversal

Enable NAT Public IP: Check the box to use the IP address of the Internet sharing device if the VoIP
Router is set up behind an Internet sharing device. Also the VoIP Router will use the IP address of the
Internet sharing device as the public IP when it connects to Internet. Furthermore, some of the Internet

sharing device’s type is symmetric NAT. You need to set Virtual Server or Port Mapping (Forwarding) from

the Internet sharing device for the listen port and communication ports (RTP ports) of the VoIP Router.
NAT IP/Domain: Enter the real public IP address of the IP sharing device or the router; or enter a true URL

(Uniform Resource Locator) when DDNS is used. Please refer to the DDNS settings.
Note: If you are setting a public IP in this field, it has to be a static public IP, otherwise VoIP communication

may not be established properly. Please contact your ISP to check if your Internet connection has static
public IP addresses.

Enable STUN Client: Check the box to use the STUN protocol prevents problems from setting the IP
sharing function. (Some NATs do not support this protocol.)

Note: You can use the “Status  STUN Inquiry” page to detect the NAT type of your Internet sharing device.

If the NAT type is “Symmetric NAT,” then the VoIP Router is not able to traverse the NAT. It is not a flaw of

the VoIP Router design, but rather a limitation of the STUN protocol.
STUN Server IP/Domain and Port: Enter the IP address and listen port of the STUN server. You can set

two STUN server IPs separated by a semicolon.
