The Multiservice Gateway

The iMG624 and iMG634 intelligent
Multiser vice Gateways provide multiple IP-
based broadband ser vices to the home over a
high-speed, always-on broadband connection.
The combined deliver y of IP Triple Play ser vices
- voice, data and video - benefits both ser vice
providers and their customers. Ser vice
providers can quickly deliver advanced ser vices
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 por ts,
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 faxes to voice interfaces for business
applications in SoHo environments.
VoIP QOS is assured through Type of Ser vice
bits (ToS), and IEEE 802.1p priority tagging. The
addition of silence suppression and local
generation of comfor t noise results in excellent
voice quality.

The iMG634W offers a backup lifeline POTS
ser vice through an FXO por t (European model
only): in case of power failure or softswitch
inaccessibility, the FXS por t is physically
switched to the PSTN connection.

IP Television

The iMG600 family is optimized for IP Video
Streaming. The iMG “snoops” IGMP packets in-
transit allowing simultaneous deliver y 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 ser vices. MPEG video
ser vice 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 suppor ts industr y leading
Quality of Ser vice (QoS) through ISO Layer 2
and 3 prioritization techniques including priority
tagging with IEEE 802.1p, Type of Ser vice and
DSCP fields. The extensive suppor t for per por t
rate-limiting in the iMG600 series enables
ser vice providers to deliver tiered data ser vices
for the wide spectrum of end customer profiles,
providing maximum flexibility in ser vice
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 Ser vice (DoS), Por t
Scanning and Web Spoofing. In addition, a
Smar t Card slot provides suppor t for future
enhancements as security cer tificates or
dedicated provisioning ID.

The iMG634W expands data deliver y options
with the addition of a built-in IEEE 802.11b/g
wireless interface. To provide data transmission
security, the wireless interface suppor ts industr y
standard security protocols such as WEP, TKIP,
WPA, 802.1x and AES.

Management & Deployment

The iMG600 series is designed to be easy to
deploy and manage. With the Zero Touch
Configurator (ZTC) software platform, the
iMG600 series can be remotely provisioned and
