| ADSL2/2+ Residential Gateways
Voice over IP (AT-RG634A/B and
AT-RG644A/B)
AT-RG644A/B)
The RG6x4 offer a choice of Voice over IP
signaling methods, namely H.323, SIP and
MGCP including NCS 1.0 profile. H.323
provides compatibility with existing H.323
services (e.g. Microsoft NetMeeting) whilst SIP
and MGCP are newer protocols, 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 are also available
comprising G.711 A-law, µ-law (64kbps), G.729
(8kbps),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.

The AT-RG634A/B allows the connection of
two standard analog phones, modems or faxes
through 2x FXS ports, or digital devices can
can be connected to the AT-RG644A/B through
1x ISDN BRI port. Class 5 services are
supported and the VoIP interoperability has
been certified versus major softswitch vendors.

Video Streaming
The RG6x4 offers unique features to optimize
the delivery of video contents to customers on
copper pair, namely VLAN, extended interleave
memory, IGMP snooping and proxying. It
supports full IGMP snooping capability (v1/v2)
and individual LAN ports can receive different
multicast transmissions e.g. different movies or
TV channels.The RG6x4 ‘snoops’ IGMP packets
in-transit, so it knows which port to forward
the particular multicast data to.This results in
high quality, high bandwidth video streaming
without affecting Internet browsing or IP
telephony on adjacent ports. Moreover, the
RG6x4 supports IGMP proxying to allow
forwarding of multicast packets at Layer 3 with
or without NAT.

Management and Configuration
The RG6x4 is designed for high volume ADSL
access network deployment; this is reflected in
the Zero Touch Configurator (ZTC), whereby
no user intervention is required when installing
a unit. ZTC is a distributed configuration system
based on the industry standard Lightweight
Directory Access Protocol (LDAP). ZTC
provides intelligent and automatic configuration
of remote RG units. It analyzes incoming status
information from each RG unit and dynamically
creates the appropriate configuration file or
operating system download as required, it then
selects the appropriate download mechanism
(e.g.TFTP, HTTP, HTTPS etc.) to complete the
process.The ZTC client in the RG initiates the
download process on power up, or on expiry
of its DHCP lease timer. ZTC provides secure
authentication of client devices, resilience
through distributed server operation and in-
built scalability for very large networks.
