1. Overview

1.1 System Features

Congratulations on your purchase of the Net2Phone MAX 410/420/430!
The MAX 410/420/430 is a VoIP device that allows you to make multiple outgoing calls over the
Internet using a single Ethernet LAN connection. The MAX 410/420/430 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 410/420/430 is a stand-alone device that connects directly into an existing LAN through an
RJ-45 port. MAX 410 contains four FXO ports, MAX 420 contains four FXS ports and MAX 430
contains 3 FXS / 1 FXO ports .
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 PBX, APBX, 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 (Foreign Exchange Office) ports connect to the analog line card on a PBX, APBX, 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 provide limited
IVR (Interactive Voice Response) functionality, which includes multiple options for caller greetings,
passwords, and Internet call forwarding. This allows the MAX 410 to assume many IVR functions
when they are not provided by the PBX.
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 Net2Phone 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
