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

Page 11: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 12: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 13: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 14: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 15: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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?

Page 16: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 17: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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:-

Page 18: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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:-

Page 19: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 20: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 21: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 22: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 23: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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

Page 24: Slide 1 Access to Bandwidth The Way Forward Peter Walker Director, Technology OFTEL pwalker@oftel.gov.uk.

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
