Slide 1
Access to BandwidthThe Way Forward
Peter Walker Director, Technology
OFTEL
Slide 2
Responses to previous DSL TG Recommendations
Approval regime for DSL-lite• Not useful as RTTE-D overtakes us
RA testing of DSL equipment• We understand cooperative testing is
now planned
Slide 3
Responses to previous DSL TG Recommendations
Promoting standards and Interoperability• Oftel promotes and supports international
standards• Compatibility testing is a matter for industry
Application of RTTE Essential Requirements• Sympathetic to this• But may not be complete solution• Need to consider ERs under ONP Directives

Slide 10
Results of consultation
Over 60 responses from a wide variety of bodies
Preliminary conclusion is that there is unmet effective demand in the SME sector
Residential sector has promise of future effective demand, but faces ‘chicken & egg’ situation at present
Operators and Service Providers’ also had current unmet demand
Slide 11
Options for Action
Customers need access to services, not access options
Service Providers prefer wide accessibility as delivered by Option 4
Operators preferred more control over service delivery and timing, as in Option 2
Options 1, 3 and 5 received less support, though Option 5 is long term goal
Slide 12
Balancing risks
If no action is taken, effective demand in the SME sector may remain unmet or seriously delayed
Similarly, effective demand in the residential sector may not emerge
But risk that regulatory intervention can distort investment decisions
Or might deter competing solutions
Slide 13
Preferred Options
Main pointers from consultation is that Option 2 and Option 4 had greatest support
Need to analyse carefully these two Options
Slide 14
Pros and Cons of Option 2
Option 2 is a form of unbundling
Would give customers competing choices of higher bandwidth access
Each operator can take its own risk and investment decisions independently of BT
Likely to stimulate innovation in the range of services
Slide 15
Pros and Cons of Option 2 (2)
But: Option 2 unlikely to deliver early availability of ‘mass-market’ higher bandwidth access
Technical difficulties in spectral management
Co-location and process issues need detailed planning
Not all Operators want to supply telephony as well - could a split be practical?
Slide 16
Pros and Cons of Option 4
Substantial proportion of UK could be covered quite quickly
Thus attractive to many Service Providers
Minimises technical and operational problems
Customers can retain BT as telephone supplier
Slide 17
Pros and Cons of Option 4 (2)
Some effective demand my remain unmet for some time
No competition in the network upgrade
Choice of technology in the hands of BT
If pace and extent of roll-out left to BT:-
Slide 18
Pros and Cons of Option 4 (3)
OFTEL would have to substitute its assessment of economic viability for BT’s
Highly unattractive
If OFTEL were to determine extent of roll-out:-
Slide 19
OFTEL’s conclusions on consultative responses
The pros and cons of Options 2 and 4 tend to balance each other
A combination of Options 2 and 4 likely to best meet overall objectives
Stimulates competition in both Service Providers and Operator markets
Differing needs of residential and SME could be met
Slide 20
Market Developments
BT is expected to announce soon its plans to roll-out ADSL based services, similar to Option 4
BT would provide wholesale access to Service Providers
And wholesale interconnect to other Operators
BT must treat its own SPs as it treats others
Slide 21
BT’s concerns over Option 2
Believes ADSL service only viable with high volumes of customers
Believes that Option 2 would take away that high volume of SME customers
Believes that Option 2 would divert resources from roll-out of Option 4
Slide 22
Next Steps:OFTEL’s initial conclusions
Still believe that combination of Option 2 and Option 4 best meets needs
Not convinced of BT’s arguments
But will commission an independent assessment of ADSL viability
And progress work on Option 2
Slide 23
Option 2 studies The NICC will be asked to produce a Spectral
Management Plan to support Option 2
Focus Groups will be established to develop guidelines for the provision of:
• Co-location facilities• Operational processes for loops
Target for this work is June 2000
Could allow Option 2 by July 2001 if agreed
Slide 24
Further consultation
OFTEL seeks rapid reactions to our preliminary conclusions
Consultation runs to 30th September 1999
Expect to announce firm conclusions by end of October
