ENUM Forum Document 6003_1_0 US Trial
FrameworkTrial Functional Roles

2
Rationale

• 6003_1_0 represents industry expectations to
• Test CC1 US ENUM infrastructure architecture
  components, EPP-based registration process and
  ENUM-based service concepts
• Explore experimental service concepts in a lab
  environment to help foster rational industry
  positions in various standards development
  efforts
• Industry has desire to implement ENUM but formal
  procurement process is expected to take time

3
Trial Principles

• The trials should
• Have a specific sunset date
• Preserve national sovereignty of each country
  sharing CC1 to determine if and how it chooses to
  participate in ENUM and the trial
• Operate in an open, neutral and transparent
  fashion
• Not confer a competitive advantage to potential
  Tier 1 (A or B) bidders in the actual procurement
  process
• Be limited to non-commercial activities defined
  by accepted test cases

4
Trial Policies

• US Trial participants will sign a MoU, between
  the LLC and each participant, agreeing to the
  criteria and final terms conditions for the
  trial.
• Trial is done on a best-effort basis using
  non-production services and facilities.
• There will be no external funding available for
  the trial. Each participant is expected to cover
  their own costs to participate.
• Tier 1B Registries
• Will make their services available to Registrars
  and Tier 2 Providers on the same terms and
  conditions.
• Will work with Registrars and Tier 2 providers
  based on trust agreement that applications for
  the delegation of an ENUM domain are valid.
• Registrars are not expected to accommodate an
  unlimited number of participants, but are
  encouraged to accommodate as many participants as
  possible.
• The activities and results of the trial will be
  made public, however proprietary activities of
  individual participants need not be included.

Trial Physical Architecture

• Trial Tier 1A
• Contains delegations for the NPAs delegated to
  the national trial Tier 1B Registries
• CC1 ENUM LLC has selected CIRA to operate
• Trial Tier 1B
• Name servers for each NPA used in the trial
  allows each nation to request delegation
  independently
• US trial would accommodate all participants
  wishing to play this role
• Trial Test Development Systems
• Trial Tier 2 providers to respond to test ENUM
  queries
• Trial Registrars to test Registry/Registrar
  interface
• ASPs to generate ENUM queries and test
  ENUM-enabled applications

Trial Activities

• Three phases to take approximately six months
• Phase 1 Registry Infrastructure
• Phase 2 Registry/Registrar Interface
• Phase 3 Application Testing
• Each phase would generate a report of results
  with suggestions for the CC1 ENUM LLC on the
  development of the various RFPs for commercial
  procurement.
• The activities of the phases are not strictly
  serial and may overlap.
• Desirable to include DNS security mechanisms
• Some have yet to be fully implemented and tested
  in commercial applications (e.g., DNS resolvers)

7
Trial Phase 1 Registry Infrastructure

• Delegation of CC1 from e164.arpa to Tier 1A
  (Note this activity is not part of US Trial, but
  an overall CC1 activity)
• Delegation of US NPAs from 1.e164.arpa to Tier
  1B(s)
• Validate national opt-in/opt-out procedure
• Delegation of some trial telephone numbers from
  ltnpagt.1.e164.arpa to Tier 2 name servers
• Load 1 or more NAPTR records for each trial
  telephone number for limited testing

8
Trial Phase 2 Registry/Registrar Interface

• Principal activity is to test automated
  Registry/Registrar interface using the Extended
  Provisioning Protocol as well as other
  standardized interfaces
• Add new registration
• Transfer existing registration to new Registrar
• Delete existing registration
• Add new NAPTR records to existing registration
• Modify existing registration NAPTR records
• Delete some NAPTR records from existing
  registration
• Study various procedures for validation and
  authentication using both external and internal
  sources of information
• Develop and test ContactInfo infrastructure as a
  replacement for Whois
• Conduct extended call/service setup and
  completion using ENUM-enabled applications

9
Trial Phase 3 Application Testing

• Service providers can validate service
  architectures
• Conducted on a non-commercial basis
• Call completion between end-points of different
  service providers should be encouraged
• Trial numbers come from official numbers
• Registrars could test automated Registrant
  interfaces

Roles

• ENUM Tier 1B Registry A Tier 1B Registry is the
  entity responsible for providing ENUM Registry
  services for US telephone numbers in full E.164
  format, including management of pointers to Tier
  2 Provider nameservers. A Tier 1B Registry does
  not handle NAPTR records but points at Tier 2
  Providers where NAPTR records associated with
  E.164 numbers are stored.
• ENUM Registrar A Registrar is an entity that
  provides registration services to Registrants.
  Registrars also are the operational contact with
  Registrants and they interface between the
  Registrant, the Tier 1B Registry and Tier 2
  Providers. A Registrar may also be a Tier 2
  Provider or may interface with other independent
  Tier 2 Providers.
• ENUM Tier 2 Name Server Provider A Tier 2
  Provider manages the ENUM fully qualified domain
  name associated with an E.164 number and acts as
  the Registrant's NAPTR records hosting company. A
  Tier 2 Provider maintains the actual NAPTR
  records that contain information for specific
  communication services.
• Authentication Agency Authentication Agencies
  are responsible for providing information that
  may be used by the Registrar in validating the
  assignment of ENUM end user E.164 numbers. An
  Authentication Agency can be a Telephony Service
  Provider or National Number Plan Administrator or
  any entity capable of providing the registrar
  with the data needed for authentication, such as
  a national hub provider or data clearinghouse.
  National hub providers and data clearinghouses
  have access to multiple data sources from
  telephony service providers and various other
  sources. The role of an Authentication Agency
  will be to provide information that may confirm
  to the Registrar that the Registrant is the
  rightful assignee of the E.164 telephone number
  that they wish to enter into the DNS.

Roles

• Telecommunications Service Provider The
  Telecommunication Service Provider (TSP) will
  become assignees for the numbering resources
  obtained under an FCC wavier by the LLC per the
  US government Terms and Conditions. As such the
  TSP will be the Blockholder(s) for allocated
  Thousands Blocks (NPA-NXX-Xs) assigned as
  numbering resources for the trial. In conjunction
  with the LLC, TSPs will
• Apply to the Pooling Administrator for thousands
  blocks
• Implement the assigned blocks in their network
  providing a point of interface for calls to trial
  numbers from the PSTN
• Manage trial number assignments from these blocks
  to other trial participants at the direction of
  the LLC and in conformance with the terms of the
  waiver under which the blocks were obtained.
• Be required to report to the LLC on the status of
  TN assignments to trial participants.
• Will, at the direction of the LLC, return all
  block assignments to the Pooling Administrator.
• Note US ENUM trial participants are responsible
  for making arrangements with TSPs to route trial
  numbers to their premises, gateways, or other
  interconnections as required in order to perform
  the trial role(s) they have chosen.
• Application Service Provider The Application
  Service Provider (ASP) will provide the
  applications directly to the ENUM end users in
  the context of the trial. The role of the ASP is
  to provide applications to the end user. The ASP
  is an entity which runs application servers that
  facilitate operation of the various data
  uploading and maintenance aspects of ENUM and/or
  the query/response/usage side of ENUM NAPTR
  records. For example, fully automated querying of
  a telephone number could be triggered by clicking
  the Send button of an end user device client in
  which the telephone number is entered as the
  address.
• ENUM Registrant/End-User Although the trial is
  not intended to be open for the general public to
  participate, it is expected that companies that
  may have ENUM-enabled applications can stand in
  for the registrant or end-user.
