Nortel IPTV Advancements Power Convergence of Entertainment, Communications

Las Vegas, Nevada (ots/PRNewswire) -

- IMS Integration and SIP-based Services Enable Anywhere, Anytime
Content and Features

Nortel(x) (NYSE: NT ; TSX: NT) is using its industry leadership in
SIP-based services and its breadth of solutions across IMS, broadband
and VoIP to develop new IPTV services and functionality that can
dramatically change the way people use their TVs for both
entertainment and communications.

"IPTV is more than simply delivering television services over an
IP network," said Walt Megura, general manager, Broadband Networks,
Nortel. "The real power of IPTV is in the merging of entertainment
and communications, the integration of telephone features into your
television experience, and the mobility of video services that follow
the user anywhere, anytime."

At its IPTV lab in Ottawa, Nortel is demonstrating the delivery of
IPTV services over Nortel's IMS infrastructure, the first step for
enabling telcos to create personalized IPTV services across wireline
and wireless networks that helps to provide long-term differentiation
from competitive offerings. Demonstrated services include
mobile-to-TV picture sharing, on-screen instant messaging and
presence, and click-to-call functionality.

"IPTV is a key investment area for Nortel, and the integration of
IPTV services within an IMS infrastructure is a fundamental part of
our IPTV strategy," said Megura. "We are also concentrating our
efforts on enabling new IPTV services that take full advantage of our
industry-leading SIP capabilities."

At the TelecomNEXT conference in Las Vegas from March 19-23,
Nortel is demonstrating some of these advanced SIP-based services
that can be offered by service providers as part of a Nortel-enabled
IPTV services bundle. Nortel will also be showcasing integrated voice
and text communications capabilities built using a new jointly
developed Application Interface (API) that enables the integration of
real-time IPTV services with Minerva's iTVManager software. Nortel is
using this jointly developed interface as a first step to bring
together Minerva's IPTV middleware platform with Nortel's IMS
solution to make content available to users anywhere, anytime, on any
device.

"Nortel is attacking the IPTV market with focus and
determination," said Megura. "A key part of that focus is in working
with our IPTV ecosystem vendors like Minerva to create new services
that can be an integral part of in IPTV bundle."
