AT-RG 600 Residential Gateway – Software Reference Manual
Preface
Purpose of this Manual
This manual is the complete reference to the configuration, management and
operation of the AT-RG613, AT-RG623 and AT-RG656 Residential Gateway, and
includes detailed descriptions of all management commands.
AT-RG613, AT-RG623 and AT-RG656 are Customer Promise Equipment (CPE)
designed to provide data and VoIP access for multiple users in Small Office/Home
Office (SOHO), Small to Medium Enterprise (SME), Branch Offices or customer
residence, wanting very fast download combining broadband access with Internet
telephony services.
Using these intelligent equipment the customer can use broadband integrated
services for telephony, Internet and Internet Video.
The VoIP residential gateway, fitted with a number of ports for interconnection of
traditional domestic appliances (telephone, fax, personal computer), acts as an
adapter for the conversion and management of all the necessary protocols for using
advanced multimedia services:
• Low cost telephony using Internet protocol (VoIP)
• Fast Internet navigation
• Video on demand
• Interactive services
The main features of the device are listed below:
• one 10/100 BaseT Ethernet port for uplink (WAN port)
• three 10/100 BaseT Ethernet ports for connecting user equipment (pc, printer, etc.)
• two analog VoIP ports for connecting two analog telephones or faxes (AT-
RG613TX(J) models) plus one analogue FXO port for connecting to PBX or to
Local Exchange (AT-RG613TXJ model only)
• two digital VoIP ports for connecting up to 8 digital telephones or faxes (AT-
RG623TX model)
• Switching function using the same analogue terminal from VoIP to PSTN

AT-RG 600 Residential Gateway – Software Reference Manual xvii
• IEEE 802.1q tag based VLAN
• QoS packet prioritization support: per port, 802.1p and DiffServ based
• Programmable rate limiting, ingress port, egress port, per port basis.
• IGMP v1/v2 snooping for multicast packet filtering
• PPPOE
• DHCP Server and Relay
• DNS Relay
• Compliant with SIP protocol and H323 v2 protocol
• TFTP - Trivial File Transfer Protocol support
• NTP - Network Time Protocol support
Configuration and management of the device through:
• Serial interface (CLI)
• Telnet
• SNMP
• Zero Touch Configuration
Moreover AT-RG613, AT-RG623 and AT-RG656 integrate advanced router features
like:
• Firewall
• Dynamic Port Opening
• Attack Detection and Blocking
• Advanced Network Address Translation (NAT)
Intended Audience
This manual is intended for the system administrator, network manager or
communications technician who will configure and maintain AT-RG613, AT-RG623
and AT-RG656, or who manages a network of AT-RG613, AT-RG623 and AT-RG656
Residential Gateways.
It is assumed that the reader is familiar with:
• The topology of the network in which the Residential Gateway is to be used.
• Basic principles of computer networking, protocols and routing, and interfaces.
• Administration and operation of a computer network.
Most of the commands described in this manual require superuser privilege and can
only be entered from a terminal or port, which has been logged with superuser
privilege.
