3. What is ENUM • ENUM is part of the convergence of Circuit Switched and Packet Networks • ENUM is defined by the Internet Engineering Task Force (IETF) and translates an E164 number into Internet Domain Names; RFC 2916- September 2000 • ENUM is about new service creation • Allows the use of a traditional telephone number in the context of different communication media, e.g., e-mail, VoIP, and therefore could facilitate the penetration of new applications into the mass market easily • Defines the use of Domain Name System (DNS) resource records to find optional : • E-mail addresses • Voice over IP SIP / H.323 servers • Voice Mail servers • Fax Machines Defined by US ENUM Forum

4. What is ENUM • ENUM works Email / SIP / URL • Enabled Applications • Voice over IP • Unified Messaging • Instant Messaging • IP Fax • Personal Web Pages Telephone Network Telephone No. ENUM No. INTERNET Mobile No. Fax No. ENUM DNS Server

5. What is ENUM • ENUM Usages Called B Caller A VoIP Network Internet Terminal (browser / outlook / VoIP Platform) VoIP Service Choose ENUM service PSTN IP Network WebSite / e-Mail Called B@xxx.co.kr www.xxx.co.kr 3 Mobile Network 4 Mobile Multi Service Terminal Mobile Handset Public Phone Service (PSTN or IP) Geographic E.164 E.164 Mobile No. 1 2 Home Phone E.164 No. Of Called B Service lists, related names and, preference Geographic E.164 ENUM DNS service Information of Called B

6. ENUM Benefits • Facilitates terminating calls to IP based networks • An important ingredient in the convergence of the PSTN, the Internet and other IP based networks • ENUM is a directory infrastructure - ENUM by itself has no value • Revenues will be driven by new value-added services and applications enabled by ENUM

7. ENUM Benefits • End User • Simplicity • One Number addressing eliminates need to remember multiple, complex addresses • Expand connectivity • Calls to non-PSTN (i.e., IP) devices can be completed • Service Provider • New services revenues • PSTN-IP Telephony • Strategic • Expand reach into the Internet

8. Current Standardization Activities • IETF • Update RFC 2916 to refer the DDD system(revision of RFC 2915) and advance • Considers various aspects of ENUM Administrative and • Current Internet Drafts • RFC 2916bis “The E.164 to URI DDDS Application” • Extensible Provisioning Protocol E.164 Number Mapping • ENUM Usage Scenarios • Registration for Enum Services of Group Messages • ITU (International Telecommunication Union) • ITU-T SG2 WP1/2 Numbering, Naming, Addressing • ITU-TSB(Telecommunication Standardization Bureau) Tier1 Delegation • ITU-T Supplement to REC. E.164 (“Operational and Administrative Issues associated with national implementations of ENUM functions”) Revised 11.2 draft • http://www.itu.int/osg/spu/enum/index.html

9. International Activities • US • US is not planning on any trial and will proceed with commercial implementation • US ENUM Forum submitted “ENUM Implementation requirements” to NTIA, DoC (Feb. 03) • Austria began national trial – 4th Quarter 02 • NIC.AT delegation of 43 cc number • VISIONng began 878-10 UPT ENUM Trial- 4th Quarter 2002 • VISIONng will perform ENUM demonstration in Apr. in US • UK • UK ENUM Group – Preliminary report • To begin UK national trial – 1st Quarter 03

16. Commercials in Korea • ’s Perspective • Customer Needs = ENUM service = Profit • Needs • Too many numbers and address to memorize • ENUM service • DNS resolution • PSTN – Internet convergence • E.164 number • Making Profit • Use its ONE-LIFE NUMBER Service (050x) as an Identifier for ENUM • Value added Service – MMS, Video Conferencing, etc.
