Transcript Folie 1 - ENUM

|.Introduction
 Quality needs time in education as in science
–
–
–
–
to teach more about new technologies
to find new services in the IT-landscape
to develop new products and services
to find group of interests
… time is a factor for quality. So we are sorry to get
slowly access for the ENUM-Trial, to present to you.

Which possibilities could be realized about
ENUM ?
 Who can use ENUM ?
|.What is ENUM
 What means ENUM ?
 ENUM: electronic telephone number mapping
 telecommunication- and internetservices could be
connected about this protocol.
 ENUM gives instructions to build telephone-numbers
as a domain in RFC2916-Protocol of the ICANN
 the „ENUM“-Domain can provide different services by
using the DNS (for E-Mail, websites, Unified
messaging)
|.What is ENUM
 An "ENUM"-Domain can manage different
services of telecommunication like:






GPS
GPRS
Fax
Voice-communication
mobile communication
and can assign them to different enddevices
|.How is ENUM working
 Enter a number by an ENUM-supported telephone
 e.g.: +49(country) 361(area-code) 3914866(user)
 The phone changes the number into a Domain and a
DNS-Request is starting in an IP-Network (WAN).
 e.g.: 6.6.8.4.1.9.3.1.6.3.4.9.E164.arpa
 In the result of DNS-Query could be found some
resource records from registration and the handling of
incoming requests for e-mails, calls,…
 The called person can talk now through PC to the
PSTN, or redirect the call automatically to a mailbox or
an other configured service in DNS or PSTN
|.What is a NAPTR RR
 NAPTR is an entry in a Domain Name System
(DNS)
 NAPTR RR:
 Naming Authority Pointer Resource Record
 With NAPTR you can decide how to handle
with requests.
 You can switch calls with SIP (Session Initiation
protocol) to the configured address.
|.What is a NAPTR RR
 10 10 u E2U+tel !^.*$!tel:+493613914866!.
 ^ Type:
Name of Resource Record
|.What is a NAPTR RR
 10 10 u E2U+tel !^.*$!tel:+493613914866!.

^ Order:
If you have the some "Order"-number, the
preference will be call up at first.
|.What is a NAPTR RR
 10 10 u E2U+tel !^.*$!tel:+493613914866!.

^ Flags:
Controlling and transformation of the requestedsystem (e.g. phone) to an URI
|.What is a NAPTR RR
 10 10 u E2U+tel !^.*$!tel:+493613914866!.

^ Service:
protocol of requested service and
resulotionservice for SIP (DNS-DNS) and E164
(PSTN - DNS) to an URI
|.What is a NAPTR RR
 10 10 u E2U+tel !^.*$!tel:+493613914866!.

^ Regexp:
regulary term for transformation of the request
|.What is a NAPTR RR
 For 6.6.8.4.1.9.3.1.6.3.4.9.e164.arpa
|.Which numbers could be registered
 The DeNIC e.G. allows to register following
numbers which consist of allowed:
 geographical numbers (e.g.: +49, +43, +81, …)
+
 area code (e.g.: 69, 361, 341, …)
 code of networks for cellphones ( 15x, 16x, 17x)
+
 telephone number (3914866, …)
|.Which numbers could be registered
 The DeNIC e.G. allows also to register following
numbers:
 national freecall numbers (0800)
 national personality numbers (0700)
 other serviceline codes like 0180,… will be accept
in future of the pilot-project
|.What is an E.164 number
 It is a recommened type of international telephone
number
 An E.164 number consist of an uniform principle:




the fixed area code for countries (Germany is +49)
an area code in the country
the number of user of the PSTN
the E.164-number is a decimal type and is acceptet to an
maximum lenght of 11 numbers
 Area code + local code + max. 11 numbers
 ( +49
/
361
/
3914866
)
|.What is an E164.arpa Domain
 Arpa is a Top-Level Domain which can be reached
about all Root-Servers and is managed by RIPE
 E164.arpa is a Second-Level Domain for ENUM
 9.4.E164.arpa is the ENUM-Domain for Germany and
is controlled by DeNIC e.G in Frankfurt/Main
 Service-providers like T-Systems offers numbers for
customers, e.g.: 6.6.8.4.1.9.3.1.6.3.9.4.E164.arpa
|.Possibilities of ENUM
 Networkelements could be found about one number
 Services could be found with one number about DNS
> E-Mail, GPS, Voice-Communication, Fax, Mailbox,…
 The User can define the handling of requests, well
known of 0700-Services
 creating a solution to connect PSTN with persons who
uses Voice over IP
 with ENUM numbers also older phones can be
connected to users in Internet
|.Who can use ENUM
 private persons who would like to know more
about this.
 ISP's who want to make profit with this service.

|.How to get a ENUM-Domain.
 1. You must be owner of phone-number
 Mobile phone
 Service line
 2. Request an ENUM-Domain
 T-Systems Berkom GmbH, DeNIC, Mobilcom, noris network
GmbH
 There are more as 100 test operators
 3. Documents
 Bill with owner
 Driving-license with address or identity card
