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

FTTx enabling technologiesTopics 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)

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!

Broadband RADIO ACCESS
P614 is also addressingissues related to radioaccess
Advantages of radio access:• potentially low cost
• fast deployment
• progressive investments
Drawbacks• partial coverage
• spectrum availability
• lack of standardisation

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

• 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 ?

ANCIT WORKSHOPTorino 30-31 March 1998 14
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

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
