Nortel at Carrier Ethernet World Congress, Madrid, Spain: September 25 - 29, 2006

SEPTEMBER 25, 2006 - Nortel is taking part in the Carrier Ethernet World Congress, Madrid, Spain September 25 - 29 where participants will be able to find out more about how the Company is addressing the rapidly growing demand for Carrier Grade Ethernet services and products.

Nortel executives will deliver the following key sessions during the four-day conference:

* Introducing Provider Backbone Transport (PBT) - Mervyn Kelly, director Carrier Ethernet, Nortel: Tuesday, September 26 at 14:10
* Explaining the IEEE’s Next Generation Ethernet standards initiatives - John Hawkins, Senior Marketing Manager, Carrier Ethernet, Nortel: Friday, September 29 at 09:40

In the exhibition area Nortel will be showcasing its Carrier Ethernet portfolio, consisting of the Metro Ethernet Routing Switch 8600 and Metro Ethernet Services Unit 1800/1850. Nortel also plans to demonstrate live how video services can be protected and guaranteed through the network with innovative PBT technology - which applies new connection-oriented forwarding principles to Ethernet.

Carrier Ethernet Interoperability Showcase
In association with the Carrier Ethernet World Congress, Nortel was one of 16 vendors that recently participated in the Carrier Ethernet interoperability showcase organized by the European Advanced Networking Test Center (EANTC). Nortel took part in the aggregation network with the Metro Ethernet Routing Switch 8600 and Metro Ethernet Services Unit 1800/1850. Hot staging took place in Berlin September 11 - 15 where the live testing successfully demonstrated interoperability between the vendors. The test network resembles a next-generation end-to-end carrier infrastructure designed for business Ethernet and residential triple play (voice, video and data) services. This network will be demonstrated at the CEWC in Madrid September 25 - 29.

Nortel Carrier Ethernet Portfolio

The following solutions form Nortel’s Carrier Ethernet portfolio:

* PBT (Provider Backbone Transport), for the first time, delivers the carrier-grade connection management characteristics of SONET/ SDH, to traditionally connectionless Ethernet. PBT is a simple point-to-point Ethernet tunneling technology that enables operators to specify the paths that packets should take across their Ethernet metros. These paths reserve bandwidth, deliver hard QoS and offer 50 ms recovery - matching the benchmarks set by existing SONET/ SDH networks.
* As the main driving force behind Provider Backbone Bridging (IEEE 802.1ah or Mac-in-Mac), Nortel was the first Carrier Ethernet vendor to bring massive scalability (up to millions of service instances per metro) as well as clear delineation between customers’ and service providers’ networks for simpler operations and enhanced security over traditional enterprise-class Ethernet.
* Nortel is driving new Ethernet OAM standards (IEEE 802.1ag, ITU Y.1731) to dramatically enhance the manageability of Ethernet to assume the operational values of circuit-based networks - delivering comprehensive fault detection, notification, isolation and troubleshooting mechanisms, as well as standardized performance monitoring tools.
