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

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.

You are now ready to finish setting up the Net2Phone MAX 4 using the MAX Web Manager.
Proceed to Section 3, Logging in to the MAX Web Manager.
2.1.2 Connecting to the MAX 4 through a Serial Cable
Although the serial connection allows you to set many of the Net2Phone MAX 4’s parameters, this
section will only explain how to connect to the MAX and obtain its DHCP IP address. The remaining
configuration tasks can then be completed more easily via the MAX Web Manager.
2.1.2.1 Using HyperTerminal
For this procedure you will need a standard serial cable (D-sub 9-pin, male-to-female, straight-
through connection) as shown in Figure 2, and a PC or Mac running the HyperTerminal terminal-
emulator program (or an equivalent), which is included in Microsoft operating systems. It is usually
found in the Programs menu, under Accessories.
Figure 2
1. With the power to the Net2Phone MAX 4 turned OFF, connect the cable from the unit’s
serial or console port to one of the PC’s serial ports. Note which of the PC’s serial ports you
are using.
2. Launch HyperTerminal and set up a new connection.
