Congratulations on your purchase of the VoIP ADSL Router
(ARV3515J-A-GP), hereafter referred to as the VoIP Router. We are
proud to provide you with a powerful yet simple communication device
for connecting your local area network (LAN) to the Internet. For those
who want to surf the Internet in the most secure way, this router provides
a convenient and powerful solution. The VoIP Router also enables service
providers to provide their residential and small office home office
(SOHO) customers with high-quality VoIP service using traditional analog
telephones and fax machines.
About the VoIP ADSL Router
The VoIP Router provides Internet access to multiple users by sharing a
single-user account. It is a cost-efficient means for service providers to
migrate their customers’ traditional analog telephones and fax machines
onto IP-based networks. This new technology provides many secure and
cost-effective functions. It is simple to configure and can be up and
running in minutes.

V OICE OVER IP (V O IP)

Voice over IP (VoIP)
An Introduction
Using Voice over IP (VoIP), instead of making calls over the regular
telephone network, calls are made over computer (IP) networks, either
through your Internet Service Provider’s connection or through your local
network. Calls made to another Internet telephone, anywhere in the world,
are generally free, while calls made to a regular telephone are generally
much cheaper than traditional long distance calls.
The basic steps involved in VoIP include the conversion of an analog voice
signal to digital, the encoding and then compression of the signal into
Internet Protocol (IP) packets. The VoIP Router is equipped with a digital
signal processor (DSP), which segments the voice signal into frames and
stores them in voice packets. Using the industry standard codecs, G.711,
G.723.3 and G.729, these packets are encoded. These IP packets are then
transmitted in accordance with International Telecommunications Union
specification SIP over the Internet to their destination where the process is
reversed.
Advantages of Using VoIP
The main advantage of VoIP the traditional Plain Old Telephone System
(POTS) is the ability to make low-cost calls over the IP network. One of
the greatest benefits is local long distance. By using a virtual phone
number with a different area code, you can keep a phone number in
Washington D.C. even though you live in San Francisco. This way, you
won’t pay expensive toll charges when calling Washington D.C., nor will
your Washington D.C. friends when they call you.
Past Problems
Internet-based telephony has been around for years but, until now, has not
reached the mainstream market. Some of the most common problems are
listed on the next page.

I NTRODUCTION
1-3
• Products with a true cost-saving advantage over standard telephones
do not have comparable call quality. Users experience a prolonged
delay making conversation difficult.
• Call-completion rates are very low due to firewalls and the use of
Network Address Translation (NAT), which renders over 50% of
residential computers unable to communicate with traditional VoIP
software.
• The user interface is complicated, and requires substantial
configuration and technical skills.
Recent Developments
Even as streaming audio and video over the Internet became common,
VoIP quality was still sub-par. What, you may ask, is the reason for this?
While it’s relatively easy to convert a song or even a video into IP-based
packets and have it arrive in decent shape, the Internet was not designed as
a two-way street, i.e., to support two-way communications as in your
typical conversation. Early VoIP calls were much like walkie-talkie speech,
halting and unsynchronized. A common trick was to let the other speaker
know you had finished talking by ending your statement with the word
“Over.” For example,
“How are you today? Over.”
“Not too good, I think I’ve the flu. Are you busy? Over.”
This method was effective, but hardly conducive to a comfortable
conversation! Therefore, substantial cost savings, although attractive, were
not enough to make up for unacceptably poor call quality. Now, however,
thanks to dedicated hardware processing and protocols like SIP, VoIP can
be as smooth as a session that uses the regular telephone network, greatly
increasing its appeal.
Equally as important to VoIP’s recent surge has been the widespread
adoption of broadband in both homes and businesses, which delivers the
bandwidth required to come close to PSTN quality.

Applications
Many advanced networking features are provided by the VoIP Router:
• VoIP Telephony
The VoIP Router has two analog voice lines (FXS) that support
independent telephone numbers. The voice ports interface directly
with analog telephones or fax machines. Advanced VoIP features
include, QoS, support for call waiting and call forwarding, caller ID
and VAD.
•WiredLAN
The VoIP Router provides connectivity to 10/100 Mbps devices,
making it easy to create a network in small offices or homes.
• Internet Access
This device supports Internet access through an ADSL connection.
Since many ADSL providers use PPPoE or PPPoA to establish
communications with end users, the VoIP Router includes built-in
clients for these protocols, eliminating the need to install these
services on your computer.
• Shared IP Address
The VoIP Router provides Internet access for up to 253 users via a
single shared IP address. Using only one ISP account, multiple users
on your network can browse the web at the same time.
•VirtualServer
If you have a fixed IP address, you can set the VoIP Router to act as a
virtual host for network address translation. Remote users access
various services at your site using a constant IP address. Then,
depending on the requested service (or port number), the VoIP

A PPLICATIONS
1-6
Router can route the request to the appropriate server (at another
internal IP address). This secures your network from direct attack by
hackers, and provides more flexible management by allowing you to
change internal IP addresses without affecting outside access to your
network.
• DMZ Host Support
Allows a networked computer to be fully exposed to the Internet.
This function is used when NAT and firewall security prevent an
Internet application from functioning correctly.
• Security
The VoIP Router supports security features that deny Internet access
to specified users, or filter all requests for specific services that the
administrator does not want to serve. The VoIP Router’s firewall also
blocks common hacker attacks, including IP Spoofing, Land Attack,
Ping of Death, IP with zero length, Smurf Attack, UDP port
loopback, Snork Attack, TCP null scan, and TCP SYN flooding.
• Virtual Private Network (VPN Pass-through)
The VoIP Router supports three of the most commonly used VPN
protocols – PPTP, L2TP, and IPSec. The VPN protocols supported
by the VoIP Router are briefly described below.
• Point-to-Point Tunneling Protocol – Provides a secure tunnel for
remote client access to a PPTP security gateway. PPTP includes
provisions for call origination and flow control required by ISPs.
• L2TP merges the best features of PPTP and L2F – Like PPTP,
L2TP requires that the ISP’s routers support the protocol.
• IP Security – Provides IP network-layer encryption. IPSec can
support large encryption networks (such as the Internet) by using
digital certificates for device authentication.

Hardware Installation
ADSL Connection
Connect your ADSL line to this port.
Fast Ethernet Connection
Connect a PC to the RJ-45 port on the VoIP Router with the provided
network cable. When inserting an RJ-45 plug, be sure the tab on the plug
clicks into position to ensure that it is properly seated.
The LAN port is dual-speed RJ-45 ports. It supports auto-negotiation, so
the optimum communication mode (half or full duplex) and data rate (10
Mbps or 100 Mbps) are selected automatically.
USB Connection
Using the USB port, connect to a secondary storage device or printer. This
port allows you to, for example, share your USB printer over the network
without needing to leave a host PC switched on.
FXS Connection
Connect a standard analog telephone set or fax machine to either of the
FXS ports on the rear panel. The FXS ports are like your local phone
service provider in that they can generate and provide a ring signal.
Note: When you have connected a device to the FXS port as you will
hear a dial tone provided by the FXS port once the handset is off-
hook.

ISP Settings
Please collect the following information from your ISP before setting up
the VoIP Router:
• ISP account user name and password
• Protocol, encapsulation and VPI/VCI circuit numbers
• DNS server address
• IP address, subnet mask and default gateway (for fixed IP users only)
Connect the System
The VoIP Router can be positioned at any convenient location in your
office or home. No special wiring or cooling requirements are needed. You
should, however, comply with the following guidelines:
• Keep the VoIP Router away from any heating devices.
• Do not place the VoIP Router in a dusty or wet environment.
You should also remember to turn off the power, remove the power cord
from the outlet, and keep your hands dry when you install the VoIP
Router.
Connect the ADSL Line
Run standard telephone cable from the wall jack providing ADSL service
to the RJ-11 (“ADSL”) port on your VoIP Router. When inserting an
ADSL RJ-11 plug, be sure the tab on the plug clicks into position to ensure
that it is properly seated. If you are using splitterless ADSL service, be sure
you add low-pass filters between the ADSL wall jack and your telephones.
(These filters pass voice signals through but filter data signals out.)
