The Multiservice Gateway
The iMG624 and iMG634 intelligent
Multiservice Gateways provide multiple IP-
based broadband services to the home o
ver a
high-speed, al
ways-on broadband connection.
The combined deliver
y 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 iMG634 series offers up to 2 FXS ports,
leveraging H.323, SIP and MGCP Voice over IP
(VoIP) protocols, with interoperability
established with major softswitch vendors.The
iMG634 suppor
ts the connection of modems
and fax
es to v
oice interfaces for business
applications in SoHo en
vironments.
V
oIP 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.
The iMG634W off
ers a backup lifeline POTS
ser
vice through an FXO port (European model
onl
y): in case of power failure or softswitch
inaccessibility
, the FXS port is physically
switched to the PSTN connection.
IP Television
The iMG600 family is optimiz
ed f
or IP Video
Streaming.
The iMG “snoops” IGMP packets in-
transit allowing simultaneous delivery of
different multicast transmissions such as
different mo
vies 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 ser
vices. 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 pro
