ADSL2/2+ Annex B based intelligent Multiservice Gateway The Multiservice Gateway
The iMG664 intelligent Multiservice Gateway
provides multiple IP-based broadband services
to the home over a high-speed, always-on
broadband connection.The combined delivery
of IP Triple Play services - voice, data and video
- benefits both service providers and their
customers. Service providers can quickly
deliver advanced services such as fast Internet,
VoIP, IPTV and video on demand in a scalable
way with complete remote management. End
users benefit by having a unique device
interconnecting all peripherals, computers,
wireless devices, analogue and VoIP telephones
to a single broadband uplink.

Voice Over IP
The iMG664 series offers 2 FXS ports and 1
ISDN port, leveraging H.323, SIP and MGCP
Voice over IP (VoIP) protocols, with
interoperability established with major
softswitch vendors.The iMG664 supports the
connection of modems and faxes to voice
interfaces for business applications in SoHo
environments.VoIP QOS is assured through
Type of Service bits (ToS), and IEEE 802.1p
priority tagging.The addition of silence
suppression and local generation of comfort
noise results in excellent voice quality.

IP Television
The iMG600 family is optimized for IP Video
Streaming.The iMG “snoops” IGMP packets intransit
allowing simultaneous delivery of
different multicast transmissions such as
different movies or TV channels.This enables
multiple high-quality, high bit-rate video streams
without impacting data traffic or IP telephony
while delivering the fast channel change that
users expect from video services. MPEG video
service management and diagnosis is possible
through dedicated commands and video quality
can be monitored using Allied Telesis’ unique
MPEG stream monitoring tool.

Data Delivery and Security
The iMG600 family supports industry leading
Quality of Service (QoS) through ISO Layer 2
and 3 prioritization techniques including priority
tagging with IEEE 802.1p,Type of Service and
DSCP fields.The extensive support for per port
rate-limiting in the iMG600 series enables
service providers to deliver tiered data services
for the wide spectrum of end customer profiles,
providing maximum flexibility in service
differentiation.
Security is assured by an integral Stateful
Inspection Firewall with NAT and an Intrusion
Detection System (IDS) to protect end-users’
networks from Denial of Service (DoS), Port
Scanning and Web Spoofing. In addition, a
Smart Card slot provides support for future
enhancements as security certificates or
dedicated provisioning ID.
The iMG664W expands data delivery options
with the addition of a built-in IEEE 802.11b/g
wireless interface.To provide data transmission
security, the wireless interface supports industry
standard security protocols such as WEP,TKIP,
WPA, 802.1x and AES.
