BT to Use Nortel's PBT Technology

by CXOtoday Staff    Jan 16, 2007

British Telecom’s (BT) announcement that it would use Nortel’s Provider Backbone Transport (PBT) technology in Metro Ethernet for all its 21st century network projects has paved way for Nortel India to roll-out projects here.

Nortel has a five-year deal to supply BT with its 8600 Metro Ethernet Switch, which sits in carrier metro nodes, and 1850 Metro Ethernet Services Unit, which sits in customer premises or the basement of buildings.

The management was waiting for the BT announcement to disclose its plans for the telecom providers here.

Ravi Chauhan, MD, Nortel said that the deployment at BT demonstrates how Provider Backbone Transport (PBT) and Multi Protocol Label Swtiches (MPLS) can co-exist. PBT will be deployed in the metro core and interface back into BT’s MPLS backbone network. It is the most cost-effective transport solution in the market today. “Pilots and beta tests are already being carried out,” he noted.

The company is in talks with Tier-1 and Tier-2 telecom providers in India and has plans to roll-out Provider Backbone Bridging (PBB) and PBT technologies in 2007. It is already working with Reliance, Tata and others in various sectors.

Chauhan informed that the company was actually waiting for successful implementation of its PBB and PBT technologies at the BT, to formally announce concrete India plans or India clients.

It may be recalled that BT had invited tenders for IP MPLS for its ambitious 21st century networks project. However, the MPLS switches hit a road block, and the company recently called for another tender for Metro Ethernets.

Anup Changaroth, director- Asia, Wireline Networks informed that the Metro Ethernet combined optical and carrier networks. He pointed out that there are many Indian cities waiting to get broadband connections. Metro Ethernets will fill in that vacuum. “We have kick started road shows propagating Metro Ethernet in India, starting with Mumbai. We will next go to Delhi.”

On Nortel’s PBB and PBT, he said, “They run on the same kind of fabric over which sound of IPTV can be deployed. We are enhancing Sonnet and STH with the help of PBB and PBT. Metro Ethernet has taken it across boards by developing multilayer architecture. We are bringing this global technology expertise to India. PBB allows ethernet and broadband to be adopted in the domain of the service provider. It can scale it to the homes of millions of subscribers. It also allows demarcation between enterprise class solution and solutions for the service provider. PBT makes Ethernet much more carrier class.”

The move will enable the company raise the quality of service and reliability of networks among the carrier class, besides ensuring faster connectivity and data transfer. Metro Ethernet Networks (MEN) would focus on infrastructure and enable enterprise to do core business.

The company will focus on integrity, determinism and quality of service, carrier class operators, scalability and agility, and multi-service convergence in its efforts towards the transition.

Nortel explains PBT as a new and disruptive alternative to MPLS in the carrier transport world that has attracted attention because of its familiar, SDH-like provisioning and management attributes. Key to its allure are claims that it’s easier and more cost-effective to manage than MPLS.
