I Introduction
Purpose of this manual
The Allied Telesis Gateway product set delivers multiple IP-based broadband services to home over high speed,
always-on broadband connection. This family of devices enables the delivery of voice, data, and video to cus-
tomer premises, offering benefits both to service providers and to final users. Service providers can quickly
deliver to their customers advanced services such as fast Internet, VoIP, and video on demand in a full scalable
way that is remotely manageable. End users get the benefit of a unique device interconnecting all peripherals,
computers, and telephones using a single uplink broadband connection.
This manual is the complete reference to the configuration, management, and operation of the AT-Gateway fam-
ily of devices. It includes detailed descriptions of all management commands.
It is assumed that the reader is familiar with:
The topology of the network in which the Intelligent Business Gateway is to be used.
Basic principles of computer networking, protocols and routing, and interfaces.
Administration and operation of a computer network.
II Intended audience
This manual is intended for the system administrator, network manager or communications technician who will
configure and maintain AT-iMG600 devices, or who manages a network of AT-iMG600 Gateways.
It is assumed that the reader is familiar with:
The topology of the network in which the intelligent Multiservice Gateway is to be used;
Basic principles of computer networking, protocols and routing, and interfaces;
Administration and operation of a computer network.

III How this Document is Organized
This preface provides an overview of the supported devices and the documentation sections that are relevant
to these devices. Using this preface, the customer should be able to see where the device fits within the ATI
iMG portfolio - and at a high level - how it is different from the other members of the family. This Preface has
four main subsections:
A description of the different types of devices, grouped by Network Interface Technology (ADSL, Active
Fiber, EPON, Modular).
A detailed list of the individual models supported - including the type of Network Interface, Number of
Ethernet LAN interfaces and the number and type of Telephony ports.
A list of functional groupings of devices that describes the unique traits of this set of devices - exclusive of
network interfaces.
A list of the different sections within the document and based on the above defined grouping - an indication
of which sections apply.
The intent of the functional groupings is to allow the customers to use the appropriate group to determine
which sections within the document apply to that set of devices, as well as identify what specific differences
there may be between the different groupings when discussing a specific topic - such as File System structure or
Switch functionality.

IV Allied Telesis Gateway Family Feature Summary
This family of devices supports IEEE 802.1Q tagged VLAN operation across its all switch ports. It therefore
offers a powerful combination of wirespeed Layer 2 switching between VLANs as well as high performance
Layer 3 routing between VLANs in one highly cost effective unit.
This family of devices integrates a Stateful Inspection Firewall with Network Address Translation (NAT) and
Denial of Service intrusion detection and blocking for protecting customer networks. Each VLAN can be
configured to be external, internal, or DMZ. With the Virtual Server features, a web or e-mail server can sit
beyond the NAT and appear like being on the public interface. The NAT implementation supports the most
popular protocols and applications including NetMeeting (H.323 and SIP), IPSec and PPPtp.
This family of devices offers the possibility to limit the egress and ingress bandwidth on each port. This feature
allows the Service Operator to offer differentiated services to each customer and protect its network from
malicious packet flooding.
his family of devices offer a choice of Voice over IP signaling methods, namely SIP and MGCP including NCS
1.0 profile. SIP and MGCP are optimized for operation over IP networks. This multiple protocol support
provides maximum flexibility for service providers, allowing them to provide an IP telephony service based on
cost and feature set, rather than being limited by the protocol used.
Similarly, a choice of different voice and data encoding algorithms is also available comprising G.711 A-law,
-law (64kbps),
G.729 (8kbps,) and T.38, so that maximum VoIP interworking is assured
with carrier class IP Gateways and network
switches. Quality of Service is provided through mechanisms such as the Type of Service (ToS) field in the IP packet, priority
tagging of voice traffic using IEEE 802.1p, as well as silence suppression and local generation of comfort noise – the result is
excellent voice quality.
Class 5 services are supported and the VoIP inter-operability has been certified versus major soft-switch
Video Streaming offers unique features to optimize the delivery of Video contents to customers, namely VLAN,
IGMP snooping, and proxying. This family of devices supports full IGMP snooping capability (v1/v2), and
individual LAN ports can receive different multicast transmissions e.g. different movies or TV channels. The
gateway ‘snoops’ IGMP packets in-transit, so it knows which port to forward the particular multicast data to.
