1. Overview
1.1 System Features
Congratulations on your purchase of the Net2Phone MAX 4!
The Net2Phone MAX 4 is a VoIP device that allows you to make multiple outgoing calls over the
Internet using a single Ethernet LAN connection. The Net2Phone MAX 4 works like a gateway to
convert the analog signal from your telephone to VoIP (Voice over Internet Protocol). It then uses the
LAN’s broadband connection to send calls over the Internet via Net2Phone’s service platform. Since
Net2Phone calls bypass most of the PSTN (Public Switched Telephone Network), the result is
significant savings on long-distance communications services.
The MAX 4 is a desktop device that connects directly into the existing LAN through an RJ-45 port. It
supports up to four analog telephones, each connected to the unit through an individual FXS port
(analog telephone port), and is intended for use by mid to large-sized groups.
The FXS port’s functionality includes placing outgoing calls and receiving incoming calls from other
Net2Phone devices. Optionally, FXS ports may be connected to the analog trunk card on PBX, APBX,
or KPS (Key Phone System) systems.
The Net2Phone MAX 4 features several proprietary QoS (Quality of Service) enhancements, including
ŸG.168 echo cancellation
ŸVoice activity detection (VAD)
ŸComfort noise generation (CNG)
ŸDynamic jitter buffer control
1.2 About This Guide
This User Guide, as well as the other instructional literature that accompanies the Net2Phone MAX 4, is
intended for people who have a moderate degree of experience installing networking equipment such
as routers, hubs, servers, and switches, and are familiar with basic wiring and cabling practices.
In addition to this User Guide, the MAX 4 is shipped with three product manuals:
ŸA Quick Start Guide that describes hardware installation, cabling, and configuration for a
basic, uncomplicated installation with FXS ports only.
ŸA Hardware Installation Guide that describes hardware installation, cabling, and safety-related
issues.
ŸA Command Reference Guide for advance configuration of the MAX 4 through a serial
connection.

1.3.3 The Hardware Setup Procedure
1.3.3.1 The Hardware Installation Guide
A Hardware Installation Guide that describes hardware installation, cabling, and safety-related
issues was provided along with your MAX 4 unit. Please read that manual in its entirety before
beginning your hardware installation. Make sure you completely understand the issues
discussed and, in particular, the safety warnings given.
1.3.3.2 Steps in the Hardware Setup Procedure
The steps you will follow to set up your Net2Phone MAX 4 are:
1. Install the MAX 4 unit in its location and connect the cabling.
2. Configure the LAN settings on the MAX 4 so that it communicates with your LAN.

1.4 Installing the MAX 4 Unit
Install the unit in a well-ventilated area. If it is to be placed on a surface be sure that all four rubber feet
are in place to allow for proper air circulation. Do not place objects in excess of 20 pounds on top of the
unit.
Please refer to the Net2Phone MAX 4 Hardware Installation Guide and observe the safety
precautions listed.
Figure 1
Proceed with installation as follows:
1. Connect the analog telephones to the RJ-11 ports.
2. Connect the RJ-45 LAN port to a hub or switch.
3. If your installation includes a PBX, connect it as illustrated in Figure 1.
4. Plug the Net2Phone MAX 4 into your power outlet and turn the unit on.

Your Net2Phone MAX 4 hardware setup is now complete. The next step is to connect the unit to your
LAN so that you can browse the MAX Web Manager.
2. Connecting Your Net2Phone MAX 4 to the LAN
Whether your LAN uses DHCP or static addresses, you can set the MAX 4’s LAN configuration in either
of two ways:
ŸVia a touch-tone keypad,or
ŸThrough the unit’s console (serial) port
Section 2 will explain how to set the MAX 4’s LAN configuration using either method.
2.1 Connecting the MAX 4 to a DHCP LAN
Section 2.1 explains how to connect your Web browser to the Net2Phone MAX 4 if your LAN uses
DHCP addressing. If your LAN uses static IP addresses, skip to Section 2.2, below.
The Net2Phone MAX 4’s default configuration is for DHCP (Dynamic Host Configuration Protocol).
Therefore, if your LAN is using DHCP, the Net2Phone MAX 4’s IP address parameters were configured
automatically when you connected it to the LAN. In this case, you only need to know the IP address that
was assigned to the unit by the LAN before you can browse the MAX Web Manager, MAX 4’s Web-
based configuration system. If your LAN is using DHCP, configuring the Net2Phone MAX 4 will entail
the following steps:
1. Obtain the MAX 4’s current IP address.
2. Log in to the MAX Web Manager.
3. Set the required configuration parameters in the MAX Web Manager.
2.1.1 Obtaining the Net2Phone MAX 4™s DHCP IP Address via a Telephone Keypad
For many users, the handiest way to query the MAX 4’s current IP address will be from a telephone
keypad. To use this procedure you will need a standard analog corded or cordless touch-tone
telephone.
1. Get a pencil and paper to write down the IP address.
2. Connect your telephone to any FXS (RJ-11) port on the Net2Phone MAX 4.
3. Pick up the telephone handset and dial ***1. The voice prompt responds, ”Your address is…”
and the IP address is announced.
4. 4. Write down the address and hang up the telephone. If you need to hear the address again,
hang up the telephone, then repeat step 3.
