1. Overview
1.1 System Features
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.
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 in Section 1.5 of this guide.

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
1.2 New System Features
The new software version 1.4.30 of the Max 8/16 and T1/E1 provides the following new
features:
 Improved Call Quality – The Max 8/16 and T1/E1 is now compatible with more state-
of-the-art gateways, such as Nuera and Cisco (when available), which greatly improves
the quality of calls with reduced latency.
 Dropped Call Prevention – The Max 8/16 and T1/E1 is now more reliable in retaining
calls in progress by re-establishing connections to call controllers if TCP connection is
lost. This feature will greatly improve dropped call problems for ADSL or Cable modem
users, as well as LAN network users.
 Enhanced Long Silence Detection – The Max 8/16 and T1/E1 uses bi-directional
silence detection, which means the Max FXO port will detect silence in both directions
to initiate a hang up. The detection is bi-directional, meaning that it will recognize
silence for a pre-configured period of time for both incoming and outgoing connections.
It recognizes when there is silence for a pre-configured period of time on both ends,
initiating a hang-up, but also recognizes when one party is talking for an extended
period of time and does not initiate a hang-up. This allows the Max 8/16 and T1/E1 to
terminate calls more effectively, increasing customer call completion while decreasing
billing time for the customer.
 Multiple Call Completion (MCC) – When callers call into the Max 8/16 and T1/E1 to
place outgoing calls, after each call has been completed, they can simply press the #
key to initiate their next call instead of hanging up and re-entering their account number
and ID.
 New Minutes Announcement – The Max 8/16 and T1/E1 now support an
announcement of the minutes remaining, as well as an account balance.
 IVR Selection Enhancement – The Max 8/16 and T1/E1 no longer require the user to
press the #key to complete a selection or a function. The Max 8/16 and T1/E1 will now
automatically complete the user’s selection within three seconds.
 Outbound Call Allow List – Max administrators can now set a class list on a port. The
class list can restrict certain numbers from being dialed on that port. For example, by
setting port 1 as a Class A port, and then setting Class A to restrict all calls beginning

Max 8/16 and T1/E1 User’s Guide Section 1 – Overview
Page 3
with “011” (all configurable in the Web Configuration page), the administrator restricts
users from placing international calls from port 1.
 Inbound Port Allow List – Max administrators can now restrict an FXO port to receive
specific incoming caller ID numbers. For example, FXO port 1 can be set to only
receive calls from one telephone number (e.g., a call center’s help number, or the
administrator’s cell phone number).
 Dedicated Fax Port Selection – The Max 8/16 and T1/E1 now enables administrators
to select a dedicated port for faxing via the Web Configuration page.
 Updated Country List in ‘Local Dialing’ Web Configuration Page – There is a more
complete country list for setting up Local Dialing in the Web Configuration page.
 Call Detail Record (CDR) Generation – Administrators can select to have CDRs
generated and sent to the Max Automated Billing System (ABS).
 RFC 2833 DTMF Enhancement – The Max 8/16 and T1/E1 now automatically corrects
the order sequence of data packets when they are received.
 Direct Inward Dialing (DID) Hunt Group – The Max 8/16 and T1/E1 can now receive
multiple incoming calls using a single DID account.
1.3 About This Guide

Max 8/16 and T1/E1 User’s Guide Section 1 – Overview
Page 4
3. If your LAN uses static addresses: an IP address, netmask, and gateway
address for the Max E1/T1.
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.
1.4.2 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 Section 2.1.1, Connecting to the Max 8/16 or
T1/E1 Through a Serial Cable).
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 Section 2.1.1, Connecting to the Max
8/16 or T1/E1 Through a Serial Cable,in this Guide.
1.4.3 The Hardware Setup Procedure
1.4.3.1 The Hardware Installation Guide
A Hardware Installation Guide that describes hardware installation, cabling,
and safety-related issues was provided along with your Max 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.
1.4.3.2 Steps in the Hardware Setup Procedure
The steps you will follow to set up your Net2Phone Max 8/16 or T1/E1 are:
1. Determine what kind of ports your unit contains and their locations
(if you do not already know).
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

Page 5
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.
1.5 Locating Your FXS and/or 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.
1.5.1 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 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.

Max 8/16 and T1/E1 User’s Guide Section 1 – Overview
Page 6
Ports also have logical numbers, used by the Routing Table, which are different from
their physical numbers. (See Section 4.5, Routing Table Configuration.)
1.5.2 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.
1.5.2.1 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.
DO NOT USE TOOLS TO PRY THE CARD FROM ITS SLOT!
DO NOT REMOVE INDIVIDUAL PORTS FROM THE AVU CARD!
1.5.2.2 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.
Figure 2 – FXS Ports

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

 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.
1.5.2.3 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.
1.6 Installing the Max 8/16 or 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.
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 Section 1.5.2, Identifying FXS and
FXO Ports.)
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

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

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 four ways:
 via a touchtone keypad,
 through a serial connection via the HyperTerminal terminal-emulator application, or
 via the Web Management Tool (see Section 3, Logging Into the Max Web Manager, and
Section 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.
2.1 Connecting the Max 8/16 or T1/E1 to a DHCP LAN
Section 2.1 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 Section 2.2,
Connecting to a LAN with a Static IP Address.
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 in to the Max Web Manager.
3. Set the required configuration parameters in the Max Web Manager.
2.1.1 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.
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.
