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].

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 i...
