Max™ Series Benefits
The benefits of the Max series include:
1) Reduced rates on calls to phones or faxes anywhere in the world
2) Even greater savings on calls from one Net2Phone device to another
3) Easily added to a corporate network and seamlessly interfaces with a current phone system
4) Provides a platform for value-added telephony services
5) Simple solution for end-user, who will not have to learn a complicated new phone system
6) Improved call quality versus standard VoIP calling
1) Reduced rates on calls to phones or faxes anywhere in the world
With the Max, low-cost calls can be placed to any phone or fax machine in the world. The caller and the
receiver of the call need not be on the same network or have the same hardware in order to realize
savings. Corporations can dramatically reduce their domestic and international communication costs,
saving up to 70%.
2) Even greater savings on calls from one Net2Phone device to another
Calls placed from any Max or Net2Phone IP Phone to another are billed at an extremely low per minute
rate. With this in mind, corporations with overseas or satellite offices can place a Max in each office, or an
IP Phone in a single-user office, to experience even greater savings. So, in addition to the cost-savings on
calls to any phone in the world, these products enable even greater savings for calls from one device to
another.
3) Easily added to a corporate network and seamlessly interfaces with a current phone system
Very simply, a business can reap the cost-saving benefits of the Max without upsetting their current
infrastructure. The Max connects seamlessly to an existing corporate LAN/Ethernet port and can be easily
integrated into a PBX system. By ensuring high-quality calling without additional investment in
infrastructure, corporations can easily measure and realize a fast return on investment. (Please see Max
Bandwidth Requirement chart on page 30 for more details on connectivity options).
10
Page 12
4) Provides a platform for value-added telephony services
In addition to low-cost calling, the Max provides a gateway to a host of value-added telephony services.
Current and future services include voice activated dialing, unified messaging, voice email retrieval, global
“800” numbers and remote dial-in.
5) Simple solution for end-user, who will not have to learn a complicated new phone system
Whether a user is calling from a standard phone connected to the Max or a phone on the PBX that is
integrated with the Max, their calling experience is seamless. Normally, users just need to dial a specific
digit to access the Max, much like they would normally dial a “9” to access the PBX. In this way,
productivity is not lost in the process of learning a complicated new phone system. The PBX can also be
programmed to route long distance calls automatically through the Max, making the dialing process
seamless to the end user.
6) Improved call quality versus standard VoIP calling
As calls are routed over Net2Phone’s private network and not just the public Internet, the quality of
service is greatly improved. The Max also features G.168 echo cancellation technology, further improving
the call quality.

To initially configure the Max, you can either:
a) Connect it to a PC by using a 9-pin RS-232C cable to connect the PC’s COM1 serial port to the Max console (pictured above) OR
b) Use a telephone connected to an FXS port to acquire an IP address. Then, you will need to use a PC for the initial account setup. This PC should be on the
same network but does not have to be connected directly to the Max.
4 AC Power Connection
Plug the Max into a power outlet.
Note: When only analog phones are connected, the FXS version of the Max does not support inbound PSTN calling, but
you can receive calls (via *72) from other Max units.

Connecting the Max™ to a PBX
By connecting the Max to a PBX, additional features such as inbound PSTN calling and remote calling can be supported.
Basically, an analog PBX would require an FXS or FXO version of the Max. The primary determinant between FXS and FXO is
the type of card and available ports present on the PBX. On the other hand, a digital PBX would require the Max T1/E1. To
better understand all of the terminology involved, below is a basic PBX overview as it relates to the Max.
PBX basics
As you know, a PBX (Private Branch Exchange) is a phone system that takes a number of telephone lines from the outside
world and makes them available throughout an office. Users on a PBX share a certain number of outside lines within the
company and have to dial a special number, such as “9”, to access an outside line. Theoretically, not everyone within the
company uses an outside line at the same time, so the number of outside lines on the PBX is usually equal to some number less
than the number of employees. In this way, utilizing a PBX is more cost effective than connecting an external telephone line to
every telephone within an organization. Here are a few key terms you should be familiar with:
Analog Line CardAn analog line card is a type of card featured on a PBX. The analog line card is used to connect an
FXO version of the Max. Another name for an analog line card is a SLIC/SLIB (Subscriber Line
Interface Card/Board).
Analog Trunk CardAn analog trunk card (ATC) is another type of card featured on a PBX. The analog trunk card is
used to connect an FXS version of the Max. Another name for an analog trunk card is a COIC/COIB
(Central Office Interface Card/Board).
CO/CO Line/Trunk LineCO stands for Central Office, typically the location where the phone company stores their telco
equipment. CO lines are physically run from this location to a business or home. A CO line is a
line with a phone number (i.e. 973-412-4444) that carries calls into and out of a residence or
business. In a business environment, these lines are typically connected to a PBX, allowing phones
connected to the PBX to carry phone calls into and out of the building.
Extension LinesExtension lines refer to the individual telephone stations on a PBX that have a separate extension
number. An extension line is a line to the PBX, not an actual outside telephone line. Extension
lines can be connected to a multi-port extension card that is attached to the PBX. When one
extension is used to dial another, the PBX acts as a voice router to transport and carry the call to
the appropriate extension.
15
Page 17
Hunt GroupA hunt group refers to a group of related phones that can be set up to share particular lines. For
example, a hunt group can be established when connecting a Max FXO unit to a PBX. When
multiple FXO ports on the Max are connected to the PBX, the phones on the PBX can be
programmed to share these lines. Users would dial their hunt group code, such as “4000”, to have
access to any of the available lines. The PBX accomplishes this by handing off the calls to the next
available FXO port on the Max. The user would only receive a busy signal if all of the lines of the
hunt group were busy. Or, in this case, the PBX could be programmed to automatically hand the
call off to the traditional PSTN phone system. A hunt group can also be established for a Max FXS
unit connected to a PBX.
IVR IVR (Interactive Voice Response) refers to the voice message options that can greet a Max FXO
caller. For example, a Max connected to a PBX extension can be set to greet the caller with a
message such as “Welcome to Net2Phone”, can require a password prior to granting access, or be
set to simply provide a standard dial-tone once accessed. As mentioned above, only FXO ports
provide IVR access. Instructions for customizing the IVR, such as providing personalized voice
messages in another language, are included in the user documentation.
Key SystemA key system is a telephone system that, for our purposes, is similar to a PBX in most respects.
One of the major differences, however, is that each extension on the system has buttons to directly
reach an outside line. Users on a key system do not have to dial a special number, such as “9”, to
reach an outside line. Key systems are sometimes referred to as a KTS (Key Telephone System) or
a KPS (Key Phone System). The Max product line has the same connection requirements for a Key
System as a PBX.
RJ-11RJ-11 refers to the physical connection utilized in standard analog phones. An RJ-11 cord connects
an analog phone to a standard, home phone jack.

If your customer has an analog PBX with an available analog line card (SLIC/SLIB), the optimal Max solution is an FXO (Foreign
Exchange Operator) version. To connect an FXO version of the Max to an analog PBX, simply use RJ-11 cables to connect the
analog line card to the FXO ports on the Max. If only one FXO port on the Max is connected to the PBX, all of the users on the
PBX will be sharing this one line. If more lines are desired, simply connect multiple FXO ports to the PBX. Then, a hunt group
can be established so that the users are sharing multiple lines. The diagram below shows all the connections necessary to
operate an FXO version of the Max:

Analog PBXs (Max™ FXS solution)
If your customer has an analog PBX with an available analog trunk card (ATC, COIC/COIB), an FXS (Foreign Exchange Station)
version of the Max can be used. To connect an FXS version of the Max to an analog PBX, simply use RJ-11 cables to connect
the analog line card to the FXS ports on the Max. If only one FXS port on the Max is connected to the PBX, all of the users on

Digital PBXs (Max T1/E1™ solution)
T
T
Most new PBXs are digital. If your customer has a digital PBX, the optimal Max solution is the Max T1/E1. To connect the Max
T1/E1 to a digital PBX, simply use an RJ-48 cable to connect the T-1/E-1 port on the Max to the T-1/E-1 port on the PBX. With
a Max T1/E1, users on the PBX share either 24 (T-1 connection) or 30 (E-1 connection) virtual lines. For example, if there are
50 phones on the PBX and the Max is connected to an E-1, these 50 users will be sharing 30 lines. The diagram below shows
the basic connections of a Max T1/E1 in a digital PBX environment:

FAQs
1) What is the FXS functionality of the Max?
FXS stands for “Foreign Exchange Station”. Very basically, you can plug standard analog phones into a
Max FXS unit. The FXS version of the Max does not support inbound PSTN calling, but you can receive
calls (via *72) from other Max units. It is possible to attach FXS lines to a PBX through an analog
trunk card (COIC/COIB).
2) What is the FXO functionality of the Max?
FXO stands for “Foreign Exchange Operator”. Basically, FXO allows you to connect the Max to a PBX
through an analog line card (SLIC/SLIB). With an FXO unit, inbound PSTN calls and remote calling are
supported.
3) What does T-1/E-1 mean?
T-1/E-1 is the standard digital interface for high capacity transmission of telephony and data
communications. North America uses the T-1 standard, which supports up to 24 simultaneous calls on
the Max, while Europe utilizes the E-1 standard, which supports up to 30 simultaneous calls. The T1/E-1 interface is a single port on the Max.
4) How do I connect a Max T1/E1 to a PBX?
Very simply, connect the T-1/E-1 port on the Max unit to the T-1/E-1 port on the PBX with an RJ-48
cable.
5) What bandwidth is required to use the Max?
The Max requires 17k bandwidth per line in order to maintain the Quality of Service (QoS).
6) How do I upgrade the Max?
Upgrading the Max unit is a relatively quick and easy process. Connect to the Web interface, click on
“upgrade” and follow the instructions. During the upgrade procedure, no calls should be made through
the Max. Upgrade times vary depending on available bandwidth, but normally take no longer than five
minutes.
22
Page 24
7) Can I call from one Max or IP Phone to another?
Yes. You can place calls from any one of the Max units to another. You can also call from the IP Phone
to a Max and vice versa.
8) How do I call from one Max to another?
To call from one Max unit to another, dial “*72” followed by the account number of the person you are
calling. If the device is connected to a PBX, the PBX can be programmed to allow for simpler dialing
conventions. For example, if the user calls a particular account number frequently (such as a Max in a
satellite office), the PBX can be programmed for speed dialing.
9) Can I call any number through the Max (i.e. 911)?
Please be aware that special emergency and informational numbers (i.e. 411, 611, 911, 0) cannot
normally be accessed through the Max. However, if you have a Max with at least one FXO port, it can
be configured so that these calls are routed through the PSTN.
10) What issues will the presence of a proxy raise?
If a proxy is present, the Max unit will not operate.
11) If I already have a Max and want to add more, what are the installation issues involved?
You would add additional Max units to a network just as you would add additional computers to a
network. Make sure there is enough bandwidth present and the appropriate IP addresses are
available.
12) What will happen if all of the lines from the Max are in use? Can I still place a call?
The PBX can be programmed so that if all of the Max lines are in use, calls will be routed through
the PSTN. If this happens frequently, it may be time to add an additional Max or additional ports in
the case of the Max 8/16.
13) Will the Max work with LCR (Least Cost Routing) systems?
FXS and T1/E1 versions of the Max will work in conjunction with PBXs that feature least cost routing.

Notes:
* Shading denotes most popular broadband services in the current market
* Bandwidth requirement for best voice quality is 17Kbps per IP call using 1 frame/packet. It is possible to make calls with less than 17Kpbs bandwidth, but call quality issues may result.
* Dial-up internet connections are not recommended to avoid possible call quality issues due to network congestion.
* The bandwidth is conserved less if silence compression is used when there is no voice traffic during the call.

VoIP Overview
Overview
Traditionally, phone calls have been made over a dedicated voice network. These calls are circuit switched in that
when a call is placed, a dedicated circuit is opened to transmit voice. On the other hand, a data network is one that
is packet switched. For example, when a call is placed, a source address sends data packets to a destination
address.
Very simply, VoIP enables the integration of voice and data on one existing network, transmitting voice utilizing
Internet Protocol. Voice is broken into pieces, encoded into individual data packets and then sent over a data
network. These data packets are then converted back from digital data to analog sound waves at the terminating
end.
VoIP primarily utilizes a private, managed network for its transmission, but can secondarily rely on the public
Internet for some transmission. Services that primarily use the public Internet are usually referred to as Internet
Telephony or Voice-over-the-Net (VON).
Advantages
As the transport costs are less expensive, VoIP can offer lower-cost calling than traditional voice networks. Lower
infrastructure costs for VoIP calling versus circuit switched calling can add to the savings.
VoIP can be seamlessly integrated into a current infrastructure and is access independent. Computers, standard
telephones, cellular phones, broadband connections, PDAs and home networking devices can all be used to access
VoIP calling.
In addition to voice, value-added telephony services can also be accessed to increase productivity. Services such as
voice activated dialing, unified messaging and voice email retrieval can all be accessed through VoIP technology.
Finally, VoIP has the advantage of sharing resources across an entire network. Thus, resources on a network are
not dedicated to a particular customer or product.

Glossary
Number(s)
10BaseT
10BaseT is a LAN transmission specification. The cable utilized with 10BaseT is an unshielded twisted pair, similar to a
telephone wire, and the transmission speed is 10 Mbps.
100BaseT
100BaseT is a LAN transmission specification. Sometimes referred to as “Fast Ethernet”, 100BaseT has a transmission speed of
100 Mbps and utilizes three different cabling variations.
A
Analog Line Card
An analog line card is a type of card featured on a PBX. The analog line card is used to connect an FXO version of the Max to a
PBX. Another name for an analog line card is a SLIC/SLIB (Subscriber Line Interface Card/Board).
Analog Trunk Card
An analog trunk card (ATC) is another type of card featured on a PBX. The analog trunk card is used to connect an FXS version
of the Max to a PBX. Another name for an analog trunk card is a COIC/COIB (Central Office Interface Card/Board).
B
Bandwidth
Bandwidth refers to the transmission capacity of an electronic line. In digital communications, bandwidth is measured in bits
per second (bps).
bps (Bits Per Second)
bps is a unit of measure for the speed of data transfer in a communications system.
C
Circuit Switching
Circuit switching is a networking technology used in the transmission of data. In circuit switching, a dedicated, albeit
temporary connection is established between two points, unlike packet switching.
33
Page 35
CO/CO Line/Trunk Line
CO stands for Central Office, typically the location where the phone company stores their telco equipment. CO lines are
physically run from this location to a business or home. A CO line is a line with a phone number (i.e. 973-412-4444) that
carries calls into and out of a residence or business. In a business environment, these lines are typically connected to a PBX,
allowing phones connected to the PBX to carry phone calls into and out of the building.
Codec
Codec is an acronym for Compression/Decompression. A codec is software or hardware that compresses digital data into a
smaller format to allow for faster transmission.
Compression
Compression is a manner of reducing the size of digital data to enable faster transmission.
D
DSL (Digital Subscriber Line)
DSL is a technology that greatly increases the digital capacity of normal telephone lines. DSL features “always-on” functionality
and is available in a variety of formats.
DNS (Domain Name System) Server
A DNS server stores IP addresses and their corresponding domain names.
DTMF (Dual Tone Multi Frequency)
DTMF refers to the audio signals generated through touch-tone dialing.
E
E-1
E-1 is the European standard digital interface for high capacity transmission of telephony and data communications. E-1
transmits at 2.048 Mbps and features two signaling channels and thirty voice channels.
Ethernet
Ethernet is the most widely used method to access a LAN. Ethernet is so common that general terms such as “LAN connection”
and “network card” usually imply an Ethernet connection. Different types of Ethernet include 10BaseT and 100BaseT.
Extension Lines
Extension lines refer to the individual telephone stations on a PBX that have a separate extension number. An extension line is
a line to the PBX, not an actual outside telephone line. Extension lines can be connected to a multi-port extension card that is
attached to the PBX. When one extension is used to dial another, the PBX acts as a voice router to transport and carry the call
to the appropriate extension.
34
Page 36
F
Full-Duplex
In telephony and data communications, full-duplex refers to the ability for communicating parties to simultaneously send and
receive information without degrading the quality of the content.
FXO Interface
FXO stands for “Foreign Exchange Operator”. With regards to the Max series, FXO enables you to connect the Max to a PBX
through an analog line card (SLIC/SLIB). With an FXO Max unit, inbound PSTN calls and remote calling are supported.
FXS Interface
FXS stands for “Foreign Exchange Station”. With regard to the Max series, you can plug standard analog phones into a Max
FXS unit. The FXS version of the Max does not support inbound PSTN calling, but you can receive calls (via *72) from other
Max units. It is possible to attach FXS lines to a PBX through an analog trunk card (COIC/COIB).
G
Gateway
A gateway is an entrance and an exit for a communications network. For example, a gateway can bridge the PSTN (Public
Switched Telephone Network) with the Internet, or an Intranet. A gateway is the link which connects both communication
mediums and allows telephone-to-telephone calls via the Internet.
H
H.323
The H.323 specification, popular for IP Telephony, defines packet standards for voice and video conferencing over LANs and the
Internet. H.323 utilizes several audio codecs, including G.711 and G.723.1.
Half-Duplex
Unlike full-duplex communications, half-duplex does not allow for the simultaneous data transmission from two parties. An
example of half-duplex communications would be a walkie-talkie.
Hunt Group
A hunt group refers to a group of related phones that can be set up to share particular lines. For example, a hunt group can be
established when connecting a Max FXO unit to a PBX. When multiple FXO ports on the Max are connected to the PBX, the
phones on the PBX can be programmed to share these lines. Users would dial their hunt group code to have access to any of
the available lines. The PBX accomplishes this by handing off the calls to the next available FXO port on the Max. The user
would receive a busy signal if all of the lines of the hunt group were busy, or the PBX could be programmed to automatically
hand the call off to the traditional PSTN phone system. A hunt group can also be set up for a Max FXS unit connected to a PBX.

I
Internet
The Internet is the global public computer network, comprised of millions of computers throughout hundreds of countries.
Within the Internet, smaller ISPs connect to regional ISPs that tie into major backbones across the world.
Internet Telephony
Internet Telephony, sometimes referred to as IP Telephony, is the two-way transmission of audio over a packet-switched
(TCP/IP) network. While sometimes used interchangeably with the term VoIP, Internet Telephony normally refers to a
transmission made primarily over the public Internet while VoIP primarily utilizes a private network for transmission.
Intranet
The Intranet is a private network that serves employees of a corporation.
IP (Internet Protocol)
Part of the standard TCP/IP protocol, IP protocol is used to route a message to a different network.
IP Address
An IP address is the address of a computer on a TCP/IP network. Every client and server on the network must have a unique IP
address.
ISDN (Integrated Services Digital Network)
ISDN is an international telecommunications standard for providing digital service to the dial-up telephone network.
ISP (Internet Service Provider)
An ISP is an organization that provides subscriber-based access to the Internet.
IVR (Interactive Voice Response)
IVR is a technology that automates a telephone answering system and allows it to respond to a user with a voice menu. Users
can then make choices, entered through their telephone keypad, which can generate additional responses. IVR technology is
popular in environments such as call centers.
J
Jitter
Jitter refers to fluctuations in transmission delay time. In the case of voice data, conversations are packaged into packets and
transmitted. Individual packets can take different routes through the varied networks that comprise the Internet. When the
time interval for the arrival of the packets is not constant, the timing fluctuations that may occur are referred to as "jitter".
36
Page 38
K
Key System
A key system is a telephone system that, for our purposes, is similar to a PBX in most respects. One of the major differences,
however, is that each extension on the system has buttons to directly reach an outside line. Users on a key system do not
have to dial a special number, such as “9”, to reach an outside line. Key systems are sometimes referred to as a KTS (Key
Telephone System) or a KPS (Key Phone System). The Max product line has the same connection requirements for a Key
System as for a PBX.
L
LAN (Local Area Network)
A LAN is a network in a confined geographical area, usually in a building or complex. A LAN consists of servers, workstations, a
network Operating System and a communications link.
P
Packet
A packet refers to a logically grouped unit of data. Packets contain a payload (the information being transmitted), originator,
destination and synchronizing information so that they can be transmitted over the most optimal route possible.
Packet Switching
Packet switching is a networking technology used in the transmission of data. Transmitted data is subdivided into individual
packets of data, each with its own unique identification and destination address. The packets can reach their destinations
through different routes, unlike circuit switching, and may also arrive in a different order than how they were sent.
PBX (Private Branch Exchange)
A PBX is a phone system that takes a number of telephone lines from the outside world and makes them available throughout
an office. Users on a PBX share a certain number of outside lines within the company and normally have to dial a special
number, such as “9”, to access an outside line. Theoretically, not everyone within the company uses an outside line at the
same time, so the number of outside lines on the PBX is usually equal to some number less than the number of employees. In
this way, utilizing a PBX is more cost effective than connecting an external telephone line to every telephone within an
organization.
POTS
POTS stands for Plain Old Telephone System.
PPP (Point-to-Point Protocol)
PPP is a communications protocol used to connect to the Internet through serial lines (i.e. POTS, ISDN).
37
Page 39
PSTN (Public Switched Telephone Network)
The PSTN is the worldwide telephone network.
Q
QoS (Quality of Service)
QoS is used to describe the level of service of a data communications system. As related to VoIP or IP Telephony, a QoS level
is normally compared to POTS quality.
R
Rack mounted
A rack mounted unit is one that is built into a cabinet with a standard panel width of 19 or 23 inches.
Real Time
Real time refers to communication where any perceptible delay is extremely minimal.
RJ-11 (Registered Jack-11)
RJ-11 refers to the physical connection utilized in standard analog phones. An RJ-11 connector holds either four or six wires
and connects an analog phone to a standard, home phone jack.
RJ-45 (Registered Jack-45)
RJ-45 is a telephone connector that holds up to eight wires and is commonly used in Ethernet devices.
RJ-48 (Registered Jack-48)
RJ-48 is a telephone connector with the same plug and socket as an RJ-45, but with different pin configurations. There are
different types of RJ-48 connectors. For example, the RJ-48C is commonly used with T-1 connections and the RJ-48S can be
utilized with 56 Kbps digital lines.
RTP/RTCP (Real time Transport Protocol/Real time Control Protocol)
RTP is an IP protocol that supports real time voice and video transmission, while RTCP is the companion protocol utilized to
maintain the QoS.
S
SLIP (Serial Line Internet Protocol)
SLIP is a communications protocol that was superseded by PPP.
38
Page 40
T
T-1
T-1 is the North American standard digital interface for high capacity transmission of telephony and data communications. T-1
transmits at 1.544 Mbps and features twenty-four voice channels.
TCP (Transmission Control Protocol)
Part of the TCP/IP networking protocol, TCP is a transport protocol that verifies correct data delivery between two systems. TCP
detects errors, or lost data, and triggers retransmission until the destination receives the correct data.
TCP/IP (Transmission Control Protocol/Internet Protocol)
TCP/IP is a networking protocol that provides communication across interconnected networks, between computers with diverse
hardware architectures, and between various operating systems.
U
UDP (User Datagram Protocol)
UDP is a transport protocol within TCP/IP that is utilized when TCP is not required. For example, UDP is used in real time voice
and video, where lost packets are ignored because there is no time to retransmit them.
V
Voice compression
Voice compression is the technology of encoding digital speech to take up less storage space for transmission.
VoIP (Voice over Internet Protocol)
VoIP refers to the two-way transmission of audio over a packet-switched IP network. (Please see page 31 for an overview of
VoIP).
