Max 8/16 and T1/E1 User’s Guide – Chapter 1
Page 1
1. Overview
Welcome
Congratulations on your purchase of the Max 8/16!
The Max 8/16 is a VoIP device that allows you to make multiple
outgoing calls over the Internet using a single Ethernet LAN
connection. The Max 8/16 works like a gateway to convert the analog
signal from your telephones 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.
System Features
The Max 8/16 is a rack-mountable device that connects directly to an
existing LAN through an RJ-45 port. It is capable of accommodating
up to sixteen (16) RJ-11 ports. These ports may be one of two
types: FXS or FXO. Your Max 8/16 may have only FXS ports, or only
FXO ports, or any combination of the two, and they may be installed
in any order.
A separate port with its own telephone line connection to the PBX (or
to an analog telephone) is required for each concurrent telephone
call (or conversation) desired. For example, if you need the capability
for five concurrent calls, then the Max must have at least five ports,
each connected to the PBX or to an analog telephone.
FXS ports are used to connect standard analog devices such as
corded and cordless telephones or fax machines. Optionally, they
may be connected to the analog trunk card on PBX, or KPS (Key
Phone System) systems. They are used to place outgoing calls over
the Internet and to receive incoming calls from other Net2Phone
devices.
FXO ports connect to the analog line card on a PBX, or KPS (Key
Phone System), or to an analog phone jack, to provide connectivity
to the Max from phones both inside and outside of the PBX system.
In addition to the FXS functions, FXO ports include IVR (Interactive
Voice Response) functionality, which includes multiple options for
caller greetings, passwords, and Internet call forwarding to remote
Max units and PSTN telephones worldwide, providing an extensive
range of economical communications options for enterprise users.
If you are unsure of which kinds of ports your unit has, refer to
Locating Your FXS and/or FXO Ports later in this chapter.

The Max 8/16 features several proprietary QoS (Quality of Service)
enhancements, including:
1. G.168 echo cancellation
2. Voice activity detection (VAD)
3. Comfort noise generation (CNG)
4. Dynamic jitter buffer control
New System Features
Version 1.5.10 of the Max 8/16 and T1/E1 provides the following new
features:
 T.38 Fax Protocol Supported – This version features
enhanced fax functionality, including built-in redundancy and
higher success rates.
IMPORTANT: Before upgrading to version 1.5.10 to
take advantage of the enhanced T.38 functionality,
please refer to the Upgrading the System Software
section on page 49 in this Guide.
 Leading Zero Area Codes Allowed – The Max 8/16 and
T1/E1 now accommodate area codes beginning with zero.
 Automatically Enabled for Fax Functionality – You no
longer need to select Fax-Only mode; the Max 8/16 and T1/E1 is
now programmed to switch to fax mode automatically.
About This Guide
This User’s Guide, as well as the other instructional literature that
accompanies the Max products, 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.
Hardware Setup
Hardware Requirements
To use the Max 8/16 and T1/E1, you will need:
1. A Max 8/16 and T1/E1 unit and power cord.
2. A Local Area Network (LAN) with a broadband connection,
which must not have proxy server caching.
3. If your LAN uses static addresses: an IP address, netmask,
and gateway address for the Max E1/T1.

Max 8/16 and T1/E1 User’s Guide – Chapter 1
Page 3
4. With FXS interfaces: a corded or cordless analog telephone,
and additional analog devices as desired for each port.
Optional: a PBX, APBX, or KPS with an analog trunk card
installed.
5. With FXO interfaces: a PBX, APBX, or KPS with an analog line
card installed.
6. A Net2Phone account number and PIN (available from your
reseller).
7. A separate port with its own telephone line connection to the
PBX, or to an analog telephone, is required for each
concurrent telephone call (or conversation) desired. For
example, if you need the capability for five concurrent calls,
then the Max must have at least five ports, each connected to
the PBX or to an analog telephone.
Additional Requirements
To configure and manage the unit, you will need:
 A PC or Mac workstation with any recent Web browser,
connected to the LAN.
 For a Max with FXO interfaces only (for initial LAN
configuration):
•HyperTerminal PC application (included in all Microsoft
operating systems), or an equivalent terminal-
emulator application.
•Standard serial cable (see Connecting to the Max
8/16 or T1/E1 Through a Serial Cable on page 13
in this Guide).
NOTE: On a Max 8/16 or T1/E1 without FXS ports
installed, the LAN settings must be configured using
a PC with a serial cable connection. For details, see
Connecting to the Max 8/16 or T1/E1 Through a
Serial Cable on page 11 in this Guide.
Hardware Setup Procedure
A Hardware Installation Guide that describes hardware installation,
cabling, and safety-related issues was provided along with your Max
8/16 or T1/E1 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.
To set up your Max 8/16 or T1/E1:
1. Determine what kind of ports your unit contains and their
locations (if you do not already know).

Max 8/16 and T1/E1 User’s Guide – Chapter 1
Page 4
2. Install the Max 8/16 or T1/E1 unit and connect the cabling.
3. Configure the LAN settings on the Max 8/16 or T1/E1 so that
it communicates with your LAN.
4. Log into the Max 8/16 or T1/E1 Web manager.
5. Finish configuring your FXS ports via the Web Manager.
6. Test your installation by making an Internet telephone call.
Locating Your FXS and FXO Ports
You need to be able to identify the Max’s ports before you can begin
configuring its LAN settings. After the LAN settings are configured,
the Max Web Manager will identify the Max’s ports. But before the
Web Manager is available, if you do not already know which ports are
present and where they are located, you can identify your ports by
physically inspecting the Max’s AVU (Analog Voice Unit) cards.
AVU cards are removable boards that contain the port interface cards
whose RJ-11 ports are visible on the Max’s rear panel. Figure 1,
below, shows the rear panel of a Max with two AVU cards installed,
each containing eight ports.
This section will explain how to remove the cards to conduct an
inspection, and how to differentiate between the port interface types.
Again, this process is only required once, before the Max’s LAN
settings are configured.
Physical Port Numbering
Figure 1 illustrates the physical port numbering on the Max’s rear
panel for a unit with 16 ports installed. (Your unit may only have
eight ports.) The Max Web Manager references these numbers when
identifying ports, setting up the Max’s features and configuring
Net2Phone calling accounts.

Figure 1 – Physical Port Numbers on the Max’s Rear Panel
As the illustration shows, the ports are numbered from upper left to
lower right. In the top row, the left-most port is port number 1 and

Max 8/16 and T1/E1 User’s Guide – Chapter 1
Page 5
the last is number 8. If you have 16 ports, the first port in the
bottom row is port number 9 and the last, at the lower right, is
number 16.
Ports also have logical numbers, used by the Routing Table, which
are different from their physical numbers. (See Routing Table
Configuration on page 36 in this Guide.)
Identifying FXS and FXO Ports
If you do not know which ports on your unit are FXS or FXO, you can
slide out the cards and read the labels on the individual port cards.
This section will explain that process.
CAUTION: The AVU boards can be damaged by static
discharge!
1. Before beginning, prepare a static-free surface on which to
place the cards when they are removed from the unit.
2. Employ an approved static-neutralizing wrist-strap and
ground wire to avoid damaging your unit with static
discharge.
REMOVING AN AVU CARD
To remove an AVU card:
1. Turn off the power to the Max unit and unplug the power
cord.
2. Place the unit on a desktop or other secure surface with the
ports facing you.
3. Turn the two thumbscrews on the top card counter-clockwise
until they are fully unscrewed (you feel springs pushing the
screws out).
4. Grasp the screws between your thumbs and forefingers and,
while pushing against the cabinet with the free fingers, pull
the card straight out of its slot. It should come free with
slight resistance.
CAUTION: DO NOT use tools to pry the card from its slot!
DO NOT remove individual ports from the AVU card!
FINDING THE PORT LABELS
 FXS port identification markings are visible on the right side
of the port card, as viewed with the AVU thumbscrews facing
you. The label can be seen at the arrow in Figure 2, below.

Max 8/16 and T1/E1 User’s Guide – Chapter 1

Figure 2 – FXS Ports
 FXO port identification markings are visible on the left side of
the port card, as viewed with the AVU thumbscrews facing
you. The label can be seen at the arrow in Figure 3, below.
Figure 3 – FXS Ports
APhysical and Logical Port Number Table, Appendix D in this Guide,
has been provided for you to write down the positions of your FXS
and FXO ports so that they are available for future reference.
REPLACING THE AVU CARD
To replace the AVU card in its slot:
1. Grasp the card securely by its two thumbscrews.
2. Slide the card into its socket. A slight resistance will be felt
as the card’s plug engages the receptacle inside the Max.
CAUTION: DO NOT force the card into its slot!
3. When the card’s bezel is flush with the rear panel of the Max,
push the two thumbscrews in and turn them clockwise to
engage their threads.

Max 8/16 and T1/E1 User’s Guide – Chapter 1

Installing the Max 8/16 and T1/E1
1. Install the unit in a well-ventilated area. If it is to be placed
on a surface rather than in a rack, 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.
CAUTION: Please refer to the Net2Phone Max 8/16 and
T1/E1 Hardware Installation Guide and observe the safety
precautions listed.
2. Connect an analog telephone to any one of the FXS ports.
(Reminder: If you are not sure which port or ports are FXS
ports, refer to Identifying FXS and FXO Ports on page 5 of
this Guide.)
3. Connect the RJ-45 LAN port to a hub or switch.
4. Connect your FXS and/or FXO ports to your PBX as per the
illustrations in Figure 4 and 5, below.
NOTE: If no FXS ports are installed on the Max, initial LAN
configuration is done via a PC connected to the Max
through its serial port, using the HyperTerminal terminal-
emulator application (or equivalent), which is included
with all MicrosoftTM operating systems. (This is optional
when FXS ports are present.) This procedure is explained
in Connecting to the Max 8/16 or T1/E1 Using
HyperTerminal on page 11 of this Guide.

When you have finished connecting the Max’s FXS and FXO ports as
illustrated above, plug the unit into a power outlet and turn it on.
Your Net2Phone Max 8/16 and T1/E1 hardware setup is now
complete. The next step is to configure the unit to communicate
with your LAN so that you can browse the Max Web Manager.
Connecting the Max to a Fax Machine
Connecting your Max 8/16 to a fax machine is as simple as
connecting the fax machine’s RJ-11 cable to an FXS port on the Max
8/16. To place a fax call, just use the fax machine as usual: dial the
desired number and then send the fax.
If you are connecting the T1/E1 to a fax machine, you must connect
the fax’s RJ-11 cable to an analog line on the PBX. Contact Reseller
Support for more details.

2. Connecting the Max 8/16 or T1/E1 to a LAN
Whether your LAN uses DHCP or static addressing, you can set the
Max 8/16 or T1/E1 LAN configuration in three ways:
 via a touchtone keypad,
 through a serial connection via the HyperTerminal terminal-
emulator application, or
 via the Web Management Tool (see Chapter 3, Logging Into
the Max Web Manager, and Chapter 4, Using the Max
Web Manager).
This section explains how to set the Max 8/16 or T1/E1 LAN
configuration using each method.
NOTE: On the Max 8/16 or T1/E1, LAN settings must be
configured using a PC with a serial cable connection using
the HyperTerminal terminal-emulator application, which is
included with all MicrosoftTM operating systems.
Connecting the Max 8/16 or T1/E1 to a DHCP LAN
This section explains how to connect your Web browser to the Max
8/16 or T1/E1 if your LAN uses DHCP addressing. If your LAN uses
static IP addresses, skip to the next section, Connecting to a LAN
with Static IP Addresses, on page 13 in this Guide.
The Max 8/16 or T1/E1 default configuration is for DHCP (Dynamic
Host Configuration Protocol). Therefore, if your LAN is using DHCP,
the Max 8/16 or T1/E1’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’s Web-
based configuration system. If your LAN is using DHCP, configuring
the Max 8/16 or T1/E1 will entail the following steps:
1. Obtain the Max 8/16 or T1/E1’s current IP address.
2. Log into the Max Web Manager.
3. Set the required configuration parameters in the Max Web
Manager.
OBTAINING THE MAX 8/16’S DHCP IP ADDRESS VIA A TELEPHONE
KEYPAD
The handiest way to query the Max 8/16’s current IP address is
usually from a telephone keypad (if an FXS port is present). To use
this procedure you will need a standard analog corded or cordless
touch-tone telephone.

Max 8/16 and T1/E1 User’s Guide – Chapter 2
Page 12
1. Get a pencil and paper to write down the IP address.
2. Connect an analog telephone to any FXS port on the Max 8/16
or T1/E1.
3. Pick up the telephone handset and dial ***1 (***1 on the
keypad).
The voice prompt responds, “Your address is…” and the IP
address is announced.
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 Max 8/16 or T1/E1 using
the Max Web Manager. Proceed to Chapter 3, Logging Into the
Max Web Manager.
CONNECTING TO THE MAX 8/16 OR T1/E1 THROUGH A SERIAL CABLE
Although the serial connection allows you to set many of the Max
8/16 parameters, this section will only explain how to connect to the
Max 8/16 or T1/E1 and obtain its DHCP IP address. The remaining
configuration tasks can then be completed more easily via the Max
Web Manager.
NOTE: If your Max 8/16 or T1/E1does not have any FXS
ports installed, its LAN settings can only be configured
using this method.
Connecting to the Max 8/16 or T1/E1 Using HyperTerminal
For this procedure, you will need a standard serial cable (D-sub 9-
pin, male-to-female, straight-through connection) 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 6 – Console Cable for Max 8/16 or T1/E1
1. With the power to the Max 8/16 or T1/E1 turned off, connect
the cable from the unit’s serial 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.
3. In the dialog box, specify the appropriate PC serial port, and
set the serial communication parameters as follows:
