Policy & Strategy
ENUM - a very simple idea!
• Take an E.164 number and create a fully qualified
domain name in a single highly defined and
structured domain

Technology Development
• ENUM Technical standards are maturing
IETF RFC 2916bis awaiting advance to draft standard
•
Internet Drafts
- The E.164 to URI DDDS Application (ENUM)
- ENUM Service Registration for H.323 URL
- enumservice Registration for SIP Addresses-of-Record
- Registration for enumservices of group messages
- Registration for enumservices web and ft
- ENUM registration for Presence Services
•
Within Europe
- ETSI TS 102 172: Minimum requirements for interoperability of ENUM Trials
Administration Aspects
• ITU-T ENUM Interim Assignment procedures in place
• RIPE NCC undertaking Tier ‘0’ role
• Within Europe
- ETSI TS 102 051: ENUM Administration in Europe
• 25 CC delegations made (8/3/2004)
ENUM - current state of play
• Many trials and plans for implementation
Recent ETSI ENUM Plugtests event included
presentations on activity in; France, Japan, UK,
Sweden, Poland, Ireland, Austria, Germany, Korea,
Netherlands, USA, Finland, Australia
• Lots of activity in the Enterprise/Infrastructure space
• Also developments in the mobile space (3GPP)
……and more
Some observations
• ENUM is viewed as a potential enabler for future
services
• Generally has regulatory support
- but also raises new issues
• There is no ‘killer application’ for initial launch but a
STRONG focus towards VoIP/SIP
• Approach towards implementation and interface
requirements varies
• Differing views on the potential role of incumbent
telco’s and their importance to ENUM
A Challenge for regulators?
• Approaches to ENUM regulation differ but…
“Whilst Regulatory issues are important they are not
THE key factor in the rollout of ENUM services”
“ENUM will succeed or fail regardless”
(Conclusions from ETSI ENUM Plugtests workshop Jan 94)
Developing ENUM Policy
• Dependent upon national approach
• Europe and US tend to favour ‘hands off’ approach
• UK has specifically excluded regulation of Internet
names and addresses from its interpretation of of the EU
Communications Directive
- The UK government cannot/will not be responsible for
developing ENUM policy
- Industry must undertake this role
- Compliance with EU Directives and over-riding national policies
remains mandatory

ENUM policy formation in the UK

Purpose of the Supervisory Board
• Facilitate an open, competitive environmenture
• Ensure the required degree of transparency
• Safeguard the integrity and rights of users
• To meet the needs of the ENUM Players
• Underpin commercial requirements through through the use
of effective contractual arrangements where deemed
necessary
• Oversee and ensure compliance with all EU and UK
regulatory requirements which impact the ENUM
environment
Some of the difficult issues
The UKEG has a work plan which includes:
• Transition arrangements to the new UK ENUM Committee
- drafting the ToRs
- establishing the legal framework for the body
- resolve financial considerations for start up and ongoing activities
- achieving the required participation
- develop and agree process
• UK Trial activities
- should it be extended?
- if so what elements should be the focus?
- how should the trial arrangements transition to commercial launch?
………..and some more!
• Tier 1 Registry arrangements
- draft ITT for Tier 1 Registry
- identify candidates for the adjudication panel
- appoint evaluation team
- set evaluation criteria
- post ITT
- evaluate response
- announce result
- complete contractual arrangements
Target date for completion is end October 04!
A few related issues that impact
ENUM, VoIP and convergent
services
Number ranges!
• ENUM should it have a separate number range?
• What number ranges for VoIP?
…..some of the issues
- geographic or non geographic?
- Publicly Available Telephony Service (PATS)?
- fixed, mobile or nomadic?
- tariffing?
- impact of multimedia?
The volume of numbers required are unknown!
Many different flavours of VoIP
• Carrier provided (PSTN replacement)
• Corporate (internal or outsourced)
• ISP VoIP (QoS, bandwidth, quality can be controlled)
• VoIP independent of the ISP (often sold on cost)
• Self provided (software download)
Regulatory obligations & concerns
• Should the same level of obligations apply?
- Universal Service Obligations
- access and interconnection
- access to emergency services is an issue
- Network resilience and QoS
- data protection
- lawful intercept
- ‘out of country’ provision
- need to ensure public awareness
‘that things may be different’
Views differ on VoIP provision
Examples:
The UK view - its PATS if:
- it’s a substitute for traditional public telephone service
or
- provides the customers sole means of access to the PSTN
In the US there are two classifications of services:
- Telecommunications - refers to transmission of information
without change in form or content
Information- capability for generating, acquiring, storing,
processing, utilising or making info available via telecomm’s
A snapshot of the future
• Network and service convergence will happen …...
…….with or without ENUM
• Transition to VoIP and other services will fuel market
competition ……………with or without ENUM
• Regulators will have to adopt a different approach if the
market is to realise its full potential…..ENUM could be the
catalyst for change
• ENUM will materialise in the commercial environment
…..…………starting in the enterprise/corporate sector
