Abstract

There are numerous applications where there is a need for interaction between the GSTN addressing and Internet addressing. This memo defines a full syntax for one specific case, where there is a need to represent GSTN addresses within Internet e-mail addresses. This full syntax is a superset of a minimal syntax which has been defined in [1].

1. Introduction

The possible elements composing a "Global Switched Telephone Network (GSTN) address in e-mail" (also known as the Public Switched Telephone Network - PSTN) can vary from a minimum number up to a really large and complex collection. As noted the minimal format and general address syntax have been defined in [1], along with the mechanism needed to define additional address elements. This memo uses this extension mechanism to complete the syntax for representing GSTN addresses within e-mail addresses and contains the IANA registrations for all newly defined elements.

In particular, the following additional address elements shall be defined:

- the detailed definition of GSTN number formats, in order to cover various alternative standard GSTN numbering schemes, (i.e. gstn- phone, sub-addr-spec and post-dial)

- the message originator and/or recipient specification (pstn- recipient)

GSTN addresses in e-mail MAY contain additional elements defined and registered in other specifications (see for example "T33S" element in [2]), but they MUST use definitions contained in this memo for those elements specified here.

In particular, "service-selector" names and "qualif-type1" elements MUST be registered with IANA, and published within the "ASSIGNED NUMBERS" document. This provides a standard mechanism for extending the element sets and should avoid unnecessary duplication. IANA Registration form templates for the purpouse of registering new elements are provided in Appendix B. In addition the IANA consideration section of this document defines the procedures required to proceed with new registrations.

A collection of forms for already defined "service-selector" and "qualif-type1" elements is listed in appendix C and appendix D respectively.

In particular, efforts have been made to maintain compatibility with elements defined in existing e-mail gateway services and standard specifications. For example, to the exten...
