The authorities involved ...

� Ministry of Traffic, Innovation and Technology + RTR– Act as an „enabler“ of ENUM– Apply for .3.4.e164.arpa at RIPE NCC and ITU-TSB

� RTR:– Become domain name holder of .3.4.e164.arpa– Create legal and technical framework– Define administrative processes on Tier 1 and 2 level– Act as a regulatory guide during the implementation phase– Participation in international fora– But: RTR not the driving force behind ENUM


The industry´s involvement ...(i.e. 1-0 to the incumbent)

� Fixed Telcos– Only incumbent Telekom Austria to play a (very !!) active role– No other providers stated interest so far to participate in trial

� Mobile Telcos– No interest stated so far to participate in trial

� Internet Service Providers– No interest stated so far to participate in trial

� Austrian Domain Registry (.at, co.at, or.at)– Strong interest, participation in trial + financial support

� Vendors– Supporting the interested players + working on innovative

solutions

Source: Policy Framework for the Austrian ENUM Trial – Version V 1.0


Major Issues of thePolicy Framework

� Competition– On ENUM Tier 2 (Registrar and Name Server Provider) it shall

be possible in any case to have fair competition on the basis ofa level playing field

� Integrity of E.164 numbering space– Integrity of E.164 numbering space and associated ENUM

domain space must be assured under any circumstances� Validation

– Necessary validations shall be possible for all players on theirrespective level (i.e. for ENUM SP, which are no TSP)

– Extent of validation to be investigated in dedicated sub-group


Validation is key ...(. . . at least for the regulator)

– To verify the identity of the ENUM subscriber– Already known (easy)– Not known (online, face-to-face, id-card, …)– Authentication (password, …)

– To verify that the ENUM subscriber is the assignee of anE.164 number

– Already known (easy)– Not known (last bill from TSP, letter of confirmation, …)

– To verify that this E.164 number is in operation with a TSP– Known, because of own customer (easy ?)– Not known (central database, directory, info from TSP, …)

– To verify that item 2 and 3 are still valid– Otherwise: cease ENUM delegation– Most problematic validation


Validation for the Trial(not suited for future commercial phase)

� Participation of subscribers already known only– later identification via billing address possible

� E.164 number shall be listed in public directory– data to be the same as in application for ENUM delegation

� Geographic and mobile numbers only– Other numbers after consultation with RTR possible

� Validation and de-validation with periodic check to bedone by ENUM service provider (registrar)

� Open issue: corporate ENUM subscribers� Evaluation of methods during trial

Summary

� Strong joint effort of industry and authority puts Austriaamongst the first to start an ENUM field trial

� RTR policy framework is intended to enable a first trialwithin a short timeframe not demanding all the problemsto be solved in advance

� Validation as well as competition are issues discussedcontroversially in the first months of the work

� Finally, we hope to see a Swiss ENUM Trial to take offsoon and would like to invite you to interwork with theAustrian ENUM Trial
