1 Overview
1.1 System Features
Congratulations on purchasing the Max 410/420/430!
The Max 410/420/430 is a Voice over Internet Protocol
(VoIP) device that allows you to make multiple outgoing
calls over the Internet using a single Ethernet Local Area
Network (LAN) connection. The Max 410/420/430 works
like a gateway to convert the analog signal from your
telephones to Voice over Internet Protocol (VoIP). It then
uses the LAN’s broadband connection to send calls over
the Internet via ’s service platform. Since Net2Phone
calls bypass most of the Public Switched Telephone
Network (PSTN), the result is significant savings on
long-distance communications services.
The Max 410/420/430 is a stand-alone device that
connects directly into an existing LAN through an RJ-45
port. The Max 410 contains four FXO ports, Max 420
contains four FXS ports and Max 430 contains 3 FXS
ports and 1 FXO port.
FXS (Foreign EXchange Station) interfaces 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 a Public
Branch Exchange (PBX), Automatic Public Branch
Exchange (APBX), or Key Phone System (KPS)
systems. They are used to place outgoing calls over the
Internet and to receive incoming calls from other
devices.
FXO (Foreign EXchange Office) ports connect to the
analog line card on a PBX, APBX, or KPS, or to an

User’s Guide Section 1
2
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 provide
limited Interactive Voice Response (IVR) functionality,
which includes multiple options for caller greetings,
passwords, and Internet call forwarding. This allows the
Max 410 to assume many IVR functions when the PBX
does not provide them.
A separate port with its own telephone line connection to
the PBX, or to an analog telephone, is required for every
concurrent telephone call (or conversation). For
example, if capability for 3 concurrent calls is desired,
then the Max must have at least 3 ports connected to the
PBX or to analog telephones.
The Max 410/420/430 features several proprietary QoS
(Quality of Service) enhancements, including:
•G.168 echo cancellation
•Voice Activity Detection (VAD)
•Comfort Noise Generation (CNG)
•Dynamic jitter buffer control
1.2 About This Guide
This User’s Guide, as well as the other instructional
literature that accompanies the Max 410/420/430, 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’s Guide, the Max 410/420/430 is
shipped with three product manuals:
•A Quick Start Guide describing hardware
installation, cabling, and configuration for a basic,
uncomplicated installation.

Max 410/420/430

•A Hardware Installation Guide describing
hardware installation, cabling, and safety-related
issues.
•A Command Reference Guide describing
advanced configuration of the Max 410/420/430
through a serial connection.
1.3 Product Enhancements for Version 1.3.5
•Improved Call Quality – The Max 8/16 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
410/420/430 is now more reliable in retaining
calls in progress by re-establishing connections
to call controllers if an IP stream is lost. This
feature will greatly improve dropped call
problems for ADSL or Cable modem users as
well as LAN network users.
•Account Balance Announcement by Port –
The Max 410/420/430 has a Web configurable
toggle switch that enables the IVR to announce
the account balance or minutes remaining on
the port that the call is going over.
•New Greeting Message - A greeting message
will play prior to the dialed call being sent to the
call servers.
•Voice file changes – Newer, clearer voice files
have been added.
•New Password Functionality - When a user
selects Password mode or Acc/Pin/Password
mode and the password field is empty, an error

User’s Guide Section 1
4
message is displayed and the password value is
not saved in flash memory.
•Call Detail Record (CDR) Generation –
Administrators can select to have CDRs
generated and sent to the Max Automated
Billing System (ABS).
•RTF 2833 Enhancement for Disordered
Packets - The Max 410/420/430 now
automatically corrects the order sequence of
data packets if they are received out of order.
•TX/RX silence detection – the Max
410/420/430 detects both TX/RX silence on an
FXO port and then disconnects the call based
on the duration of call silence.
•Multiple Frames per Packet Support - Now
the Max 410/420/430 supports multiple frames
per packet on the G.732 codec.
•Upgraded Vocfiles – Updated vocfile included
with software upgrade.
•Fax Mode Support – Fax only mode feature
added in web configuration, which allows the
Max 410/420/430 to connect to a server that can
handle fax data transmission.

1.5Locating Your FXS and/or FXO Ports
You need to be able to identify the Max’s physical
port numbers before you can begin configuring its
LAN settings.
The RJ-11 sockets are visible on the Max’s rear
panel. Figure 1, below, shows the rear panel of a
Max with 4 ports.
1.5.1 Physical Port Numbering
Figure 1 illustrates the physical port numbering on
the Max 410/420/430’s rear panel for a unit with 4
ports installed. These numbers are referenced by
the Max Web Manager when identifying ports,
setting up the Max’s features and configuring calling
accounts.
Figure 1
Figure 2

User’s Guide Section 1
8
As the illustration shows, the ports are numbered
from left to right. The left-most port is port number 1
and the last one on the right is number 4.
Ports also have logical numbers, used by the
Routing Table, which are different from their physical
numbers. Logical port numbering is where the FXS
and FXO ports are counted separately, and the
count starts from zero instead of one (See Section
4.5, Routing Table, in this Guide).
1.6 Installing the Max 410/420/430 Unit
Proceed with installation as follows:
1. Install the unit in a well-ventilated area. If it is to
