BT to Switch Voice Calls to IP as 21st Century Network Takes Shape

First 1,000 customers to trial high quality voice services on new IP network


BT to trial limited wider use of optical fibre in access network

    NEW YORK, June 9 /PRNewswire-FirstCall/ -- BT's transformation of its
 network to deliver the next generation of communications services took a step
 forward today with the announcement of a pilot for the switch-over of voice
 calls to an end to end IP (Internet Protocol) based network.
     BT also announced trials of niche deployments of fibre to the premises,
 aimed at testing the technical and commercial issues involved.
     BT Wholesale chief executive Paul Reynolds said: "We've been talking about
 our vision for our 21st century network and today marks the start of the
 transition from planning stage to physical implementation.
     "The 21CN programme will deliver today's services at better cost by
 removing duplication in our networks and underpin the delivery of services
 customers will want in the future.  For customers, the end result will be a
 complete experience -- one based on convenience and ease of use of all
 communications services including mobility, video, data services and voice."
     As a precursor to large scale migration of voice and other PSTN based
 services from 2006, the first stage in the migration pilot will involve the
 bypass of the core PSTN network link between two major network nodes at
 Cambridge and Woolwich.  An extension is planned later to Faraday exchange in
     From October 2004, BT will divert voice calls between these network nodes
 to the 21CN specific IP network. Calls will be carried using IP packet
 technology rather than the circuit switched technology used on PSTN.  The
 switch-over will be seamless from the customer's perspective and service
 quality will be the same or better than on PSTN.
     The next stage of this pilot involves the installation of new equipment at
 18 exchanges in South East London, Kent and East Anglia -- which are connected
 to the network nodes in Cambridge and Woolwich. This equipment, known as multi
 service access nodes (MSANs), will carry voice and data services onto the core
 IP based network, initially for 1,000 customers by January 2005.
     Paul Reynolds added: "We want to be absolutely clear that using IP
 technology in our network for our premium quality voice services is a gulf
 apart from the new budget voice over the internet services being launched
 almost daily by a wide range of providers.
     "We believe we can provide these services over IP at the same or better
 than the high standards of quality and reliability people expect from the PSTN
 today.  These calls are not going over the internet.  They will be carried on
 our dedicated high capacity IP networks which also carry data and broadband
     "Adopting IP as the common transport method is both cost efficient and
 facilitates technology, systems, product and service convergence.  BT's vision
 is that voice will be one of many applications run over an IP network in our
 21st century network world."
     BT today also announced 21CN programme fibre to the premises trials at
 Martlesham Heath, Suffolk; at Kents Hill, the Bolbeck Park and Walnut Tree
 developments in Milton Keynes; and at the Waterfront Studios business centre,
 at Silvertown in London's Docklands.
     The trials will provide telephone and broadband services over fibre for up
 to 1,500 homes and businesses.  The first trialists will have their fibre
 lines installed and working in October 2004 and the trial will run until
 September 2005.
     Paul Reynolds said: "As part of our 21CN programme, BT is looking at the
 potential that fibre in the access network can deliver for our customers and
 the investment and operational requirements that go with it.  If the
 commercial case is proved, we could begin to consider the role that fibre may
 have further out in the network in the future.
     "We expect the real benefits of this trial to be in informing our thinking
 on the relative costs and benefits of deploying fibre, rather than copper, to
 homes and businesses in green-field sites or new-build developments."
     BT's 21CN programme aims to migrate the company's existing multiple,
 service specific networks to a single converged multi-service IP based
 network.  It includes work towards increasing the bandwidth of services
 provided over the copper access network as well as the trials of fibre
     Paul Reynolds added: "At this stage we don't envisage a widespread
 deployment of fibre to the premises or the cabinet in the near or medium term.
 While we believe the use of fibre can help deliver better operating costs in
 terms of maintenance, we need to balance this against the cost of installation
 and systems developments.  These trials will help to shape our thinking and
 help us make strategic investment decisions."

     PSTN to IP transformation trial
     The initial customers to use IP based networks for end-to-end services
 previously carried on the PSTN will largely be BT employees in the exchange
 areas below.  The deployment to these trialists will provide valuable
 information about the technicalities and practicalities of the future
 large-scale migration of services.  The pilot will be extended to 3,000
 customers in June 2005 prior to large-scale migration in 2006.

     BT has selected the following companies to support the PSTN to IP pilot:
      * Marconi is supplying core network Softswitches and multi-service access
        nodes (MSANs) for voice services.
      * Alcatel is providing IP ethernet switching equipment.
      * Siemens is supplying metro media gateways and Juniper core and edge
     Fibre to the premises trial
     The fibre to the premise trial will involve the installation of new fibre
 optic cables between a BT exchange and the property of those taking part.
 Telephone and broadband services provided will be on a second line in parallel
 to services currently provided over the BT network.  Optical network units at
 the exchanges and customer premises to manage the interface between the fibre
 and BT and customer equipment.
     ECI is supporting the fibre to the premises trials by supplying optical
 network units for use at customer premises and optical line termination
 equipment at the exchange.
     Supplier contracts
     BT is today formally launching the procurement process to select long term
 suppliers for 21CN, which may not necessarily be those involved in the trials
 and early implementation stages. Contracts for the main rollout phases will be
 awarded following a formal competitive tendering process that will be
 concluded by the end of 2004.
