ANCIT WORKSHOP Torino March Access Network in EURESCOM Projects, and the P614 Project Umberto Ferrero CSELT (P614 Project Leader) Participants coming from 12 companies (EURESCOM Shareholders) Michalis Mavis P614 EURESCOM Project Supervisor

ANCIT WORKSHOP Torino March P614 is becoming increasingly popular as a reference source of independent broadband access network recommendations -WEB sites -request for reprints and documents from operators, -manufacturers, journalist and consultants all over the world Conferences, magazines, workshops Deliverables are public domain P614 as source of “access network” information

ANCIT WORKSHOP Torino March EURESCOM and the access network: managing the European diversity Shareholders -over 20 Telecom Operators (Telcos) -... with several service and network scenarios -no “one size fits all” approach Identification of areas of common interest Access network-related studies since Common results (EURESCOM P306 and P413) -Customer-specific customization FSAN ATM - PON

ANCIT WORKSHOP Torino March Access network in EURESCOM P306: Access network evolution and preparation for implementation P413: Optical networking in the local loop WOMAN WORKSHOP BAHN WORKSHOP P614: Implementation strategies for advanced access networks Outline of specifications for broadband access networks Migration paths towards B-ISDN access networks Exploration of broadband radio access FTTx enabling technologies FTTH architectures, services and technical issues Techno-economic evaluation and comparison of identified B- ISDN/ATM based network alternatives ANCIT WORKSHOP

ANCIT WORKSHOP Torino March P614 addresses several access network architectures

ANCIT WORKSHOP Torino March Access as a commodity? Satellite CATV network Powerlines PSTN (existing copper plant) Broadband overlay network Fixed radio access Mobile Several access infrastructures can be exploited in the same area USER

ANCIT WORKSHOP Torino March Target technologies for fixed access FSAN based PON solutions -identified as technology of choice by EURESCOM P306 (April 1994, “Guidelines for broadband access networks”) -full PON specification now available (ITU-T G.983) -approaching market availability Point to point systems... both complemented by a range of high speed copper access systems ATM common platform

ANCIT WORKSHOP Torino March FTTx enabling technologies Topics addressed by P614 Component technology -Maturity and cost Outside plant technology -Cabling, ducting, connectors, cabinets -Powering -Testing Transmission technology -Point to point links (access and drop) -Exploitation of WDM -Alternative drop technologies (CDSL, powerlines) RFI on Plastic Optical Fibres (POFs)

ANCIT WORKSHOP Torino March Down to earth... or under the ground: the importance of outside plant technologies -powering -cabinets -digging, ducting -cabling 70% of the access network costs is due to infrastructure: how this burden can be reduced? -Re-using copper wires -Adopting innovative installation techniques!

ANCIT WORKSHOP Torino March Optical cabling elements for FTTx

ANCIT WORKSHOP Torino March Broadband RADIO ACCESS P614 is also addressing issues related to radio access Advantages of radio access: potentially low cost fast deployment progressive investments Drawbacks partial coverage spectrum availability lack of standardisation UMTS Terrestrial solutions LMDS / MMDS GEO, LEO Satellites RLAN

ANCIT WORKSHOP Torino March Techno-economic evaluation Rationale Techno-economics is an on-going concern Advantages of comparison carried out by an independent body with the PNOs direct expertise Targets Update of former results Realistic price of equipment for new technologies Comparison of identified B-ISDN network alternatives Broadband radio evaluation Flexible adaptation of results to local needs

ANCIT WORKSHOP Torino March What is the cost of bandwidth ? Are ADSL and HDSL solutions attractive ? HFC technology is a cheap solution, or not ? What about the BPON architecture ? FTTx (but how close to the customer ?) x = ??? CAPACITY UPGRADE What is the cost to upgrade ? What is the financial risk ? Some techoeconomic considerations INITIAL INVESTMENT $ $ $ $

ANCIT WORKSHOP Torino March The challenge of the broadband access network implementation Time for real deployment -focus on practical issues End of a single architecture -access network as a combination of technologies, keeping a comprehensive overall network perspective Ability to support the changing needs of Operators -there is still opportunity for cooperation in a competitive environment -coordinated contribution to standardization bodies -techno-economic evaluations The three key messages

ANCIT WORKSHOP Torino March P614 Deliverables

ANCIT WORKSHOP Torino March WHAT AFTER P614 ? A number of advanced access networks are available Interoperability and field operation testing is needed Considering that... P614 proposes... The creation of a co-ordination platform for lab testing of broadband access equipment, broadband home network technologies, fixed-mobile broadband access network demonstrations co-ordinating these activities with the FSAN actions.... Proposals for WP-1999
