Middleware Platform, Interconnection With Nortel IMS Infrastructure

TelecomNEXT - Minerva Networks and Nortel(x) (NYSE: NT ; TSX: NT)
today announced the joint development and release of an 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.

Using Session Initiation Protocol (SIP), the new API gives
developers and service providers the tools needed to enable real-time
applications such as voice mail access and callback functionality
over the television set. This innovative development environment also
provides service providers with investment protection through support
for legacy non-SIP systems including Caller ID and instant messaging
as well as well providing a foundation for future IMS services.

"Minerva has over 65 customers around the world who are anxious to
introduce advanced communications services with their IPTV offerings.
The joint development of our new open API makes this a possibility,"
explained Matt Cuson, VP of Marketing for Minerva Networks. "We are
excited to be working with Nortel and other system integration
partners to make our open platform easily accessible for telcos
looking to offer innovative services."

"Nortel's collaboration with Minerva is a critical part of our
efforts to deliver IPTV services over a standards-based IMS
infrastructure," said Walt Megura, general manager, Broadband
Networks, Nortel. "Nortel is committed to providing advanced IMS
services that integrate with home entertainment networks and make the
television set a more personalized communications tool."

The robust API enables key communications features such as
click-to-call, network address book, buddy lists, mobile-to-TV text
and picture messaging and the ability to configure communications
services directly through the set-top box (STB). The Minerva
iTVManager platform has been enhanced to leverage a broad range of
capabilities in Nortel's standards compliant SIP solutions.

Roger Musick, CEO of Innovative Systems said, "We were one of the
early companies to integrate Caller ID services with the iTVManager
platform and we are pleased to see Minerva and Nortel promoting
standard IPTV APIs. Telcos need to deploy advanced communications
capabilities to differentiate their offerings. This new API and SIP
will help make it possible."

The iTVManager platform is targeted to support Nortel's SIP and
IMS (Internet Protocol Multimedia Subsystem) infrastructure. SIP,
used for establishing sessions in an IP network, makes a host of
on-screen services possible, including e-commerce, click-to-dial,
Instant Messaging and voice mail. IMS replaces the control
infrastructure of a traditional circuit- switched phone system and
decouples voice and other services from the underlying delivery
networks making new service deployments faster and easier.

statements and related events and that the previously filed financial
statements of Nortel and NNL and related audit reports should not be
relied upon; the negative impact on Nortel and NNL of their announced
restatement and delay in filing their financial statements and

EDC would refuse to issue additional support under the facility,
terminate its commitments under the facility or require NNL to cash

information guidelines of such regulatory authorities; (ii) risks and
uncertainties relating to Nortel's business including: yearly and
quarterly fluctuations of Nortel's operating results; reduced demand
and pricing pressures for its products due to global economic
conditions, significant competition, competitive pricing practice,

consolidation, rapidly changing technologies, evolving industry
standards, frequent new product introductions and short product life

telecommunications industry; any material and adverse affects on
Nortel's performance if its expectations regarding market demand for
particular products prove to be wrong or because of certain barriers
